You type a prompt over breakfast, pick the image you like best, and have it on a listing by lunchtime. A week later a stranger in another country orders it as a print for her hallway. You have never met her, and your picture is on her wall.
That feels good when the rest of life feels stuck. Maybe your design job got squeezed by the same AI tools you are now using. Maybe the bills arrive faster than the paycheck, and your friends seem to be pulling ahead with side incomes you keep meaning to start.
Platforms are tightening fast. Every month there are more AI designs fighting for the same searches, and the rules on ownership and disclosure keep shifting. The sellers who learn those rules now and build a focused catalogue stand out while the bulk uploaders get filtered away. Waiting puts you behind a wall of copies.
Etsy charges you 0.20 US dollars to list, keeps the listing live for four months, then takes 6.5% when someone buys. A print listed at 15.99 US dollars can bring a royalty of 0.96 US dollars, so the volume has to be there before the money is. Starting costs nothing if you already have a generator, and under 100 US dollars covers it if you pay for one. Two to six weeks is a fair wait before your first steady sales, with 300 US dollars a month the low end of what a working catalogue brings in.
Tonight, open the terms of the generator you use and find the sentence about who owns your outputs. That answer shapes every listing you make after it.
The mechanics are simple. You generate images with a text-to-image model. You upload them to a print-on-demand supplier or marketplace. When a customer orders, the supplier prints your design onto a poster, a mug, a t-shirt or a phone case, ships it, and pays you the difference between the retail price and their base cost. You never touch inventory. Making one more design costs you close to nothing.
That last sentence cuts both ways for you. It is why getting in is so easy, and it is why getting in is just as easy for everyone else.
This page walks you through what you can and cannot legally claim to own, what each platform's published policy actually says, what the base costs and margins really are using figures from the suppliers' own pages, why the saturation problem is built into the model and will stay, where the trademark landmines are, and what you have to disclose and to whom. Where I could not confirm a number from a primary source, I say so.
There are three distinct models, and each has its own economics and its own way of failing you.
Almost everyone starts with the first or second model. Almost all the failure happens there too, for reasons the rest of this page lays out.
Your honest starting goal is small. If a handful of posters and mugs leaves you $300 after production and selling costs over thirty days, your phone plan gets paid without dipping into the grocery money, from designs you shaped and checked yourself. Which bill in your house would that $300 cover first? Pick one niche you understand and make your first ten listings there.
In January 2025 the United States Copyright Office published Part 2 of its report on copyright and artificial intelligence, which deals specifically with whether AI outputs can be copyrighted. Its conclusions are stated plainly in the executive summary:
Read the Office's reasoning on prompts closely, because it shuts the door on the workaround most people try first. The report says: "Prompts essentially function as instructions that convey unprotectible ideas. While highly detailed prompts could contain the user's desired expressive elements, at present they do not control how the AI system processes them in generating the output."
A longer prompt will not help you. A 400-word prompt will not help you either. The Office considered exactly that argument and rejected it, drawing on joint-authorship case law: "The provision of detailed directions, without influence over how those directions are executed, is insufficient."
Two months later, on 18 March 2025, the D.C. Circuit confirmed the human authorship requirement as a matter of statutory law in Thaler v. Perlmutter, holding that "the Copyright Act of 1976 requires all eligible work to be authored in the first instance by a human being." That case was about a machine listed as the author, a narrower question than yours, but it ended any argument that the Copyright Office is inventing a requirement Congress never imposed.
What this means for you in practice: if your listing image is an unmodified model output, you have no copyright in it at all. Zero.
Think about your best-selling idea for a moment. If a stranger copied it tomorrow and undercut you by a dollar, what would you actually be able to do? The next few sections answer that, and the honest answer shapes how you should build this.
The report leaves some doors open. It names three routes to protection, and each one has a specific shape.
Look at what that note does for you. It protects your drawing. The rendering, lighting, shading and texture the model added stay unprotected. If a competitor copies your finished image, you can only assert rights in the human parts anyone can see.
The counter-example in the same report is Suryast. A photographer supplied his own photograph and told an AI system to apply the style of Van Gogh's The Starry Night. The Review Board refused registration because the applicant "exerted insufficient creative control" and, unlike Rose Enigma, the output did not clearly show the copyrightable input work.
The report also says that tools which "enable the user to control the selection and placement of individual creative elements" sit in a different category from prompting alone, with copyright decided case by case under the Feist originality standard.
Where on that ladder does your current workflow sit? If you already draw or take photographs, the bottom rung is within your reach, and it is the only rung that gives you something to defend.
If you do decide to register something, the Copyright Office's registration guidance (Copyright Registration Guidance: Works Containing Material Generated by Artificial Intelligence, published at 88 Fed. Reg. 16190, 16 March 2023) puts a positive duty on you. In its words: "applicants have a duty to disclose the inclusion of AI-generated content in a work submitted for registration and to provide a brief explanation of the human author's contributions to the work."
In practice, you must use the Standard Application (the Single Application is closed to you here), describe your human contribution in the "Author Created" field, and exclude AI-generated content that is "more than de minimis" in the "Limitation of the Claim" section under "Material Excluded". You are told not to list the AI tool or its vendor as an author.
The consequences of skipping this are spelled out. The guidance says applicants who fail to update the record "risk losing the benefits of the registration," that the Office may cancel a registration where essential information "has been omitted entirely from the application or is questionable," and that "a court may disregard a registration in an infringement action pursuant to section 411(b) of the Copyright Act if it concludes that the applicant knowingly provided the Office with inaccurate information, and the accurate information would have resulted in the refusal of the registration."
That last point is the sharp one. If you quietly register AI output as your own painting, you gain no protection. You create a document that can be used against you, and you sign a statement to a federal agency.
Registration fees, from the Copyright Office fee schedule: 45 US dollars for a single application (one work, one author, not made for hire, filed electronically), 65 US dollars for the Standard Application, 125 US dollars on paper. Since AI-assisted works need the Standard Application, budget 65 US dollars per registration, and remember the fee is charged per work. A whole portfolio only goes on one application if it is a genuine collection.
Where you and your buyers live matters here more than in almost any other online income idea, because you may be selling into countries whose law differs from yours.
On paper that is kinder to you than the US position. In practice nobody has tested it: the UK Intellectual Property Office's 2022 consultation outcome found no case law applying the provision to AI, concluded that "it is unclear whether removing [protection for computer-generated works] would either promote or discourage innovation," and left the law alone. A further UK consultation on copyright and AI opened in December 2024. Do not build your business on the assumption that section 9(3) definitely covers a Midjourney output; nobody has litigated it.
Hong Kong (Copyright Ordinance section 11(3)), India (Copyright Act 1957 section 2(d)(vi)) and New Zealand (Copyright Act 1994 section 5(2)(a)) have similar computer-generated works provisions, with the same lack of any ruling on how they apply to generative models.
If you sell globally (and print-on-demand marketplaces are global by default), you are working under several of these regimes at once. Take local advice before you claim ownership anywhere you do not live.
Every major generator says something comforting in its terms. Read the qualifier.
Midjourney's Terms of Service say: "You own all Assets You create with the Services to the fullest extent possible under applicable law." In the United States, applicable law is what the Copyright Office and the D.C. Circuit have just described to you. The clause hands over whatever Midjourney has; it cannot create a copyright the law withholds.
Midjourney's published plan prices are 10, 30, 60 and 120 US dollars per month for Basic, Standard, Pro and Mega, with a 20% discount if you pay a year upfront (96, 288, 576 and 1,152 US dollars per year). Unlimited generations in Relax Mode start at the Standard plan. Stealth Mode starts at Pro, which is 60 US dollars a month or 48 US dollars a month billed annually.
For you as a seller, that distinction maps exactly onto the two risks: indemnity protects you on defence, and copyright would have protected you on attack. You can only have the first.
This is where the copyright position lands on your shop.
Under 17 U.S.C. section 411(a), "no civil action for infringement of the copyright in any United States work shall be instituted until preregistration or registration of the copyright claim has been made in accordance with this title." You cannot sue without a registration. You cannot get a registration for purely AI-generated material. So you cannot sue anyone in a US federal court for copying it.
Under 17 U.S.C. section 412, even where a registration exists, you get no statutory damages or attorney's fees for infringement that began before registration, unless you registered within three months of first publication. Statutory damages under 17 U.S.C. section 504(c) run from 750 to 30,000 US dollars per work, rising to 150,000 US dollars for wilful infringement and falling to 200 US dollars for innocent infringement. Without registration you are limited to actual damages and the copier's profits, and for a poster listing that sold four copies, that sum will not even pay for a lawyer's first phone call.
That is the picture when you try to act. The picture when someone acts against you is worse, because the same design you cannot protect can be copied by somebody else and listed on the same marketplace within an hour, with no legal consequence for them. How would you feel watching that happen to your best design in your first month? Plan your catalogue so that one stolen design is a shrug.
What about DMCA takedowns? A notice under 17 U.S.C. section 512(c)(3) requires a statement, under penalty of perjury, that you are the copyright owner or authorised to act for them, and a good-faith belief that the use is unauthorised. Filing takedowns against copies of material you hold no copyright in exposes you to liability under section 512(f) for knowing material misrepresentation. Marketplaces also count bad notices against your account. This constraint is real, and it is why experienced sellers in this niche do not bother filing.
Redbubble's own help centre is candid about how far platform enforcement goes. Its article on why similar works stay live explains that content is removed when "identified as infringing in a legally valid takedown notice," and that "we generally don't go looking for similar works to remove from the marketplace." Platforms respond to valid notices. Policing lookalikes for you is outside what they do.
What is left for you? Three things, all weaker than copyright.
- Trade dress and brand. A consistent shop identity, a registered word mark, a recognisable product line. Trademark protects source identifiers and leaves the pictures themselves alone, but it is the one right in this business you can actually own and register.
- Contract and platform terms. Marketplaces will act on duplicate-listing and account-abuse policies where the copying is wholesale, though enforcement is patchy and you cannot appeal it.
- Speed. Being first, and being cheapest to reprice. This is an operating habit with no legal force behind it, and it works only until someone with more upload capacity spots your listing.
If your business plan needs a design to stay exclusive to you, this tactic cannot give you that.
Copyright law sets the floor. The shops you sell through write their own rules on top of it, and those are the rules that close your account.
The three biggest venues publish materially different rules, and the differences sit in places most people do not expect.
Etsy
Etsy allows AI-generated art and has a specific published disclosure rule. Etsy's Creativity Standards state that sellers "must disclose within their listing description if an item is created with the use of AI," and its help documentation repeats that "seller-prompted AI creations must disclose the use of AI." Etsy's seller handbook describes its stance as allowing "AI-generated art where a seller utilizes their unique creative lens and abilities, in addition to being transparent about their process."
Etsy sorts listings into categories, and your AI-assisted work belongs under "Designed by a seller", which Etsy's own materials describe as "Original designs by a seller (or seller-prompted AI art) offered as a digital download or produced/printed by a third-party". It does not go under "Made by a seller." If you use a print-on-demand supplier, that supplier is a production partner, and Etsy requires you to disclose it separately: "Sellers must disclose that an item is made by a production partner, and provide accurate information about where the item will ship from."
So an Etsy print-on-demand listing built on generated art carries two disclosure duties for you: the AI disclosure in the description, and the production partner disclosure in the listing's production partner field. Etsy publishes no fixed penalty schedule for a missed disclosure. Removing the listing and acting against your account are both within its stated discretion.
Note also that Etsy blocks automated access to its own policy pages, so the exact wording can change without any easy way for you to compare versions. Check the live Creativity Standards page before you rely on the wording quoted here.
Etsy's fee structure, taken from Etsy's 2025 annual report on Form 10-K, filed 19 February 2026, the most reliable primary source because it is a filing made under securities law:
- Listing fee: a fixed 0.20 US dollars per item listed, recognised over a four-month listing period, non-refundable.
- Transaction fee: 6.5% per completed transaction, "inclusive of shipping fees charged."
- Offsite Ads: a further transaction fee of "12% or 15% of the value of a sale based on the seller's volume of sales" where the sale came from an Etsy-placed advertisement on a third-party platform. Etsy's help documentation states the Offsite Ads fee "for any individual order will never exceed $100 USD."
- Payments processing fees are charged separately and vary by country.
I could not confirm the exact per-country payment processing rate from Etsy's own fee page, because Etsy returns HTTP 403 to automated requests. Check the rate for your country in Etsy's Fees and Payments Policy before you model your margins.
Amazon Merch on Demand
You have to apply to get into Amazon Merch. You submit a request and, in Amazon's words, "we will provide you with an expected timeframe for a decision and we will notify you of the decision via email." Approval is never automatic and the queue is not published. The programme is non-exclusive: Amazon confirms you may put the same design up elsewhere.
Amazon Merch has no published AI disclosure requirement. Its Content Policies page prohibits illegal or infringing content, offensive or controversial content, and a list of other categories, and says nothing at all about disclosing generative tools. That is a real difference from Etsy that you can check yourself, and it matters when you choose where to list. Silence on AI still leaves every IP warranty fully in force against you.
What the Content Policies do say, and it bears directly on you, is that Amazon prohibits "content incorporating intellectual property (such as trademarks, copyrights, or the name or likeness of others) that you do not have the right to use," and that this "may include text, visual representations of designs, patterns, products or other objects (for example, certain car models), or photographs." Amazon then links to the trademark registers for each of its marketplaces (USPTO for the US, UKIPO, EUIPO and TMDN for the UK, DPMA for Germany, J-Plat Pat for Japan), an unusually direct instruction to search before you upload.
The same document tells you what happens if you get it wrong: Amazon "may take corrective actions, such as immediately suspending or terminating Content Creator privileges, removing listings, terminating the business relationship, or permanently withholding payments."
Royalty structure. As Amazon's own Royalties page sets out, your royalty is your product's offer price less applicable tax and less Amazon's costs, with a multiplier based on your royalty group. In the US store there are three groups:
- Creator: standard rates.
- Plus: for creators who "actively drive at least 15% of unit sales with non-organic traffic," paying 2x the Creator rate.
- Premium: for those driving at least 35% of unit sales with non-organic traffic, paying 2.16x the Creator rate.
To qualify for Plus and Premium you must sell at least 10 units per month in the US store. Groups update monthly on a trailing two-month average. Amazon states that "royalty rates for sales outside of the US store remain unchanged," and that accounts with no sale in over a year may be moved to inactive status.
The Creator rates for a standard t-shirt in the US store, from Amazon's published examples:
- 15.99 US dollars list, 0.96 US dollars royalty
- 17.99 US dollars list, 1.70 US dollars royalty
- 19.99 US dollars list, 2.44 US dollars royalty
- 21.99 US dollars list, 3.18 US dollars royalty
- 23.99 US dollars list, 3.92 US dollars royalty
- 25.99 US dollars list, 4.66 US dollars royalty
Two things fall out of that table for you. First, at the popular 19.99 US dollars price point your royalty is 12.2% of the list price. Second, every 1 US dollar you add to the price adds 37 cents to your royalty. Amazon keeps 63 cents of every extra dollar. So raising your price is a weak lever unless your sales hold up, and at higher prices they usually fall.
Some product lines are far worse. Amazon's published example for the Comfort Colors Adult Sweatshirt in the US store shows a 35.99 US dollars list price returning a 0.29 US dollars Creator royalty: under 1% of the list price. The same product at 39.99 US dollars returns 1.69 US dollars. If you list on Merch without reading the royalty table for the specific garment, you can spend an afternoon making listings that can never pay you. How many t-shirts at 2.44 US dollars each would you need to sell to cover your generator subscription this month? Do that sum before you open the upload page.
Amazon also requires 300 dpi PNG files sized to the 15 by 18 inch printable area, and states in the Services Agreement that it is the seller of record with "sole discretion to determine price, availability, distribution channels, and terms of sale."
Redbubble
Redbubble publishes no dedicated AI-generated content policy article in its help centre. A search of its help centre in August 2026 for "artificial intelligence" returned a single unrelated match. Silence still gives you no permission; Redbubble's intellectual property policy still requires you to hold the rights to what you upload, and its help centre states plainly that "the Redbubble marketplace is a place to display and sell your original artwork."
What Redbubble does publish, and what matters far more to you as an AI-art seller, is how it classifies accounts. Redbubble's help article on account classification (updated 8 July 2026) lists among its considerations:
- "Origin of the artwork (i.e., uploading high volumes of low-effort or repetitive designs and using unmodified vector packs, clip art, or royalty-free images)"
- File quality
- Consumer appeal
- Tag spamming or inaccurate information in titles and descriptions
That first bullet describes the standard AI print-on-demand workflow almost word for word. Redbubble allows AI art; it charges you more for behaving like a bulk uploader.
The fee consequence. Redbubble's account tiers decide the platform fee taken from your gross earnings each payment period (help article updated 31 July 2026):
| Artist tier | Platform fee |
|---|
| Standard | 50% on monthly earnings |
| Premium | 20% |
| Pro | no platform fee |
Fees for Standard and Premium artists are capped at 150 US dollars, 150 euros or 150 pounds per payment period. Separately, an excess markup fee applies: Redbubble says no fees apply to product markups at or below 20%, and that a 50% fee comes off gross earnings made above that threshold for Standard and Premium artists. Pro artists pay neither.
Redbubble's default artist margin is 20% of the base price; its own worked example says that "20% of the $20 base price means you earn an artist margin of $4.00 (before account fees)." On a Standard account that 4.00 US dollars becomes 2.00 US dollars after the 50% platform fee. On a Premium account it becomes 3.20 US dollars. On Pro it stays at 4.00 US dollars.
The payment threshold dropped on 1 July 2026 from 20 to 10 US dollars, pounds or euros. Below that, your earnings roll over.
Printful, Printify and the other white-label suppliers
These are suppliers, and they bring you no customers. Their published pricing, checked 5 August 2026:
Printful. Free plan at 0 US dollars per month with access to its catalogue and integrations. Printful Growth at 24.99 US dollars per month, waived once you reach 12,000 US dollars per year in sales, giving "up to 33% off product pricing," 9% off product branding and 25% off sample orders. Sample base prices:
- Enhanced Matte Paper Poster: from 6.25 US dollars at the smallest size; 10.25 US dollars at 12 by 18 inches; 11.50 US dollars at 18 by 24 inches; 15.95 US dollars at 24 by 36 inches
- Unisex Staple T-Shirt (Bella + Canvas 3001): from 10.75 US dollars
Add-on costs Printful publishes: printed inside apparel labels 0.99 US dollars each, printed outside labels 2.49 US dollars each, premium images from Getty 1 US dollar per image per placement per item sold, embroidery digitisation 2.95 to 6.50 US dollars one-off per design, extra embroidery placements 2.95 US dollars.
Shipping is charged separately on every order and varies by destination and category. Printful's rate table shows the rates for the visitor's own region, so I could not capture the US domestic poster rate here; the rate shown for a single shirt to Malaysia was 11.99 US dollars with 6.00 US dollars per additional product. Pull your own region's figures from Printful's shipping page or its downloadable CSV before you price anything.
Printify. Free plan with 5 stores. Premium from 39 US dollars per month billed monthly, or from 24.99 US dollars per month billed annually, giving "up to 20% discount on all products" and up to 33% on new products. Printify's own profit calculator on the pricing page shows a fulfilment cost of 8.77 US dollars for a Unisex Jersey Short Sleeve Tee, excluding shipping and taxes. Printify works through 90-plus print providers, so the base cost of the same product changes depending on which provider you route to. That is the single biggest variable you control in Printify's economics.
Both suppliers charge you the moment the order is placed, on your stored payment method. On every order, you are out of pocket until the marketplace pays you.
The unit economics, with real base costs
That covers the legal and platform ground. Next comes the money question: what one sale actually leaves in your hand.
A worked poster example on Etsy
Say you sell an 18 by 24 inch matte poster to a US buyer at 42.00 US dollars with shipping built into the price, fulfilled by Printful, listed on Etsy.
- Retail price: 42.00 US dollars
- Printful base cost, 18 by 24 inch Enhanced Matte Paper Poster: 11.50 US dollars (confirmed)
- Printful shipping, US domestic, posters: estimated at 10.00 US dollars. This could not be confirmed: Printful's rate table geolocates to the visitor's region. Verify for your own selling region.
- Etsy listing fee: 0.20 US dollars (confirmed; this is per listing per four months, so it is 0.20 US dollars only if the listing sells exactly once in that window)
- Etsy transaction fee at 6.5% of 42.00 US dollars: 2.73 US dollars (confirmed rate)
- Etsy payment processing: estimated at 1.51 US dollars. Etsy's per-country rate could not be confirmed from its own page.
Total costs: 25.94 US dollars. Gross margin: 16.06 US dollars, or 38% of the retail price.
Now add one variable that catches new sellers out. If Etsy attributes that sale to Offsite Ads, it charges 15% of the total order amount for sellers below its volume threshold. That is a further 6.30 US dollars, taking your margin to 9.76 US dollars, or 23%. Sellers above the volume threshold pay 12% and cannot opt out.
Then take off the cost of your design tool, any advertising you ran yourself, the sample you should have ordered, and income tax. A 42 US dollar poster leaves you far less than a 42 US dollar business.
A worked Amazon Merch example
A standard t-shirt at 19.99 US dollars in the US store, Creator group: 2.44 US dollars royalty per sale, confirmed from Amazon's published table. You pay no listing fee, no monthly fee, no fulfilment cost, and no advertising unless you choose to buy it.
To reach the Plus group you must drive at least 15% of unit sales through non-organic traffic and sell at least 10 units a month, at which point the same shirt pays you 4.88 US dollars. Premium, at 35% non-organic and the same minimum volume, pays 5.27 US dollars.
Notice how that scheme is built. Amazon pays you roughly double for bringing your own traffic. If you can bring traffic, you are already most of the way to running your own storefront, where you would keep far more than 5.27 US dollars on a 19.99 US dollar shirt. If you cannot, you are on 2.44 US dollars and fighting on Amazon's search results page against everyone else who also cannot. So which are you today: someone with an audience, or someone hoping to borrow Amazon's? Your answer tells you which of these three examples to model first.
A worked Redbubble example
A product with a 20 US dollar base price and the default 20% markup gives you a 4.00 US dollar artist margin, per Redbubble's own example. After account fees:
| Tier | Amount |
|---|
| Pro | 4.00 US dollars |
| Premium | 3.20 US dollars |
| Standard | 2.00 US dollars |
New accounts are classified after first-time setup, and the criteria explicitly count against high-volume, low-effort, repetitive uploads. A bulk AI portfolio is the profile most likely to land on Standard, the tier that pays you half. Raising your markup above 20% to make up for it triggers the 50% excess markup fee on earnings above the threshold, which is exactly why that fee exists.
At roughly 16 dollars left per poster sale on Etsy in the example, the maths gets concrete fast. A few dozen sales a month, if you can hold them and your own costs hold too, is the birthday dinner for your sister where you order without scanning the prices, paid for by prints hanging in strangers' hallways. Model your margin per product before you upload another design.
There is a different reward too. The first time someone tells you your print made their tiny flat feel like home, you remember why you liked making pictures in the first place. Keep that feeling close when the numbers look small.
The saturation problem, quantified
People usually talk about saturation vaguely. You can put numbers on it.
From Etsy's 2025 Form 10-K: as of 31 December 2025 the Etsy marketplace had 5.6 million active sellers, 86.5 million active buyers, and "more than 100 million items for sale." Etsy marketplace gross merchandise sales for 2025 were 10,460.7 million US dollars.
Divide GMS by active sellers and you get roughly 1,868 US dollars of gross merchandise sales per active seller per year. That is about 156 US dollars a month, before Etsy's fees and before the cost of goods. The figure is a mean, and it misleads you in both directions, which is exactly why I give it with its caveats and keep it well away from any claim about average income.
It understates in one way: Etsy defines an active seller as "a seller who has had a charge or sale in the last 12 months." A charge counts. Someone who listed four items, paid 0.80 US dollars in listing fees and sold nothing is an active seller in that count. So the denominator is padded with people who never ran a business.
It overstates in a more important way: marketplace revenue is extremely lopsided. A small number of shops take a large share of GMS, which drags the mean far above the median. Etsy does not publish how GMS is spread across sellers, so the median cannot be worked out from public filings. Anyone quoting you a "typical Etsy seller income" is either using this mean without telling you, or making it up.
The structural point behind the arithmetic: there are more than 100 million items listed and 86.5 million buyers. Item count is growing faster than buyer count, and generative tools are the reason. When a new design costs almost nothing to make, supply keeps growing until the last listing added earns roughly nothing. That is the resting point this technology produces, and it will outlast any trend.
Every platform has answered with a friction mechanism, and once you see them that way, they make sense:
- Etsy's 0.20 US dollar listing fee, charged per item per four months, is a tax on spray-and-pray. Ten thousand listings cost you 2,000 US dollars every four months whether they sell or not.
- Redbubble's account tiers charge bulk uploaders 50% where careful sellers pay nothing.
- Amazon Merch gates entry by application: you request an account and wait for a decision, and Amazon publishes no approval criteria. Amazon is also widely reported to cap how many designs a new account may keep live, expanding that allowance as you sell. That upload-cap system could not be confirmed from any Amazon-published page: it is missing from the Royalties page, the Content Policies, the Services Agreement and the public FAQs, and every specific tier figure in circulation traces back to third-party blogs. Treat any number you read for it as unverified.
So "generate a thousand designs" will not work for you. Every platform has already priced that in. If you could only list fifty designs this year, which fifty would you choose, and why those? That question is closer to the business that works.
The flood of low effort designs grows every week, and the platforms keep raising the bar to filter it out. A focused, careful catalogue built now has time to earn reviews before the next round of restrictions. Starting later means meeting tighter rules with no track record behind you.
Trademark risk lives in your prompts
Copyright is the protection you cannot use. Trademark is the risk that can actually cost you money, and generative models walk straight into it.
Here is how it happens. Ask a model for a design in the style of a well-known franchise, or featuring a recognisable character, mascot, logo, catchphrase, car silhouette or celebrity likeness, and it will give you something close enough to get you sued. The model knows nothing about the trademark register. You are expected to.
Registered trademark exposure. Under 15 U.S.C. section 1117(a) a successful plaintiff may recover your profits, their damages and costs, and a court "may enter judgment... for any sum above the amount found as actual damages, not exceeding three times such amount," with attorney fees available in exceptional cases. Where counterfeit marks are involved, section 1117(c) lets the plaintiff choose statutory damages of "not less than $1,000 or more than $200,000 per counterfeit mark per type of goods or services," rising to "not more than $2,000,000 per counterfeit mark per type of goods or services" for wilful use. Those amounts are counted per mark per goods type, however many sales you made.
Copyright exposure from someone else's characters. This is a separate question from whether you own your own output. If your generated image reproduces protected expression from a copyrighted character or artwork, statutory damages under 17 U.S.C. section 504(c) run from 750 to 30,000 US dollars per work infringed, up to 150,000 US dollars if wilful.
Right of publicity. Putting a real person's name or likeness on merchandise engages state-law publicity rights in the United States, which vary a lot between states in scope, duration and cover after death, and separate regimes in other countries. There is no single national rule. Check the law of the state or country where you sell.
The subtler trap: ordinary phrases. Trademark registers are full of short, generic-sounding phrases registered for clothing in International Class 25. A slogan that seems obviously free for anyone may be registered by somebody who will send you a takedown. Amazon's Content Policies link straight to the searchable registers: USPTO for the United States, UKIPO, EUIPO and the TMDN common register for Europe and the UK, DPMA for Germany, J-Plat Pat for Japan. The habit to build is searching every phrase in the relevant class before you upload. It takes about ninety seconds, and they are the best-spent ninety seconds in your whole workflow. What is the funniest slogan you were planning to print? Search it tonight, before you fall in love with it.
Registering your own mark. If you want to build a brand that outlasts this business, USPTO fees under the January 2025 fee structure are a base application fee of 350 US dollars per class of goods or services, plus a 100 US dollar per class surcharge for insufficient information, plus a 200 US dollar per class surcharge for using the free-form text box instead of the Trademark ID Manual, plus 200 US dollars per additional 1,000 characters in that box. Intent-to-use applications add 150 US dollars per class for a statement of use and 125 US dollars per class for an extension. Maintenance is 325 US dollars per class for the five-year declaration and 650 US dollars per class for the combined ten-year renewal. Fees differ in every other country.
Three separate disclosure regimes
People mix these up. Each stands on its own, and you can satisfy one while breaking another.
Platform disclosure. Etsy requires you to disclose AI use in the listing description and, separately, your production partner. Amazon Merch's published content policies require neither. Redbubble publishes no dedicated AI disclosure rule. These are contractual rules, enforced by removing listings and acting against accounts, and they change without warning.
Copyright Office disclosure. As set out above, you have a duty to disclose AI-generated content on any registration application, with cancellation and section 411(b) consequences if you do not. It only applies if you register, and if you do, it applies in full.
EU AI Act transparency obligations. Article 50 of the AI Act became applicable on 2 August 2026. Two provisions matter here, and they land on different parties.
Article 50(2) requires providers of AI systems that generate synthetic audio, image, video or text to "ensure that the outputs of the AI system are marked in a machine-readable format and detectable as artificially generated or manipulated." That duty sits with the model provider (OpenAI, Midjourney, Adobe). What it means for you as a seller is that your generated files may carry provenance metadata that platforms can read.
Article 50(4) requires deployers of AI systems that generate or manipulate image, audio or video content constituting a deep fake to disclose that the content has been artificially generated or manipulated. It has a carve-out: "Where the content forms part of an evidently artistic, creative, satirical, fictional or analogous work or programme, the transparency obligations set out in this paragraph are limited to disclosure of the existence of such generated or manipulated content in an appropriate manner that does not hamper the display or enjoyment of the work."
A decorative abstract poster falls outside any sensible idea of a deep fake, and Article 50(4) does not obviously bite on it. A design showing a real, identifiable person in an invented scene plausibly counts, and the artistic carve-out shrinks the duty while leaving some of it in place. This provision is new and untested; if you sell into the EU and your designs show real people, take advice before relying on this paragraph.
Advertising and consumer law. This one is separate again, and the one most likely to cause you trouble in practice. Describing an AI-generated poster as "hand-painted," "original watercolour" or "drawn by me" misdescribes the product, and that is actionable under general consumer protection law in every country on this page, whatever the AI-specific rules say. The safe wording is plain and factual: say the artwork was created using AI tools, say what you contributed, and stop.
The rules differ a lot by country. Check where you live; what follows is a starting map, and you should treat it as orientation only.
United States. Payment platforms report on Form 1099-K. The IRS's current guidance describes the threshold as payments for goods or services that exceed 20,000 US dollars in more than 200 transactions. That threshold has moved several times in recent years, so confirm the figure for the tax year you are filing. Most importantly, the reporting threshold has never decided whether your income is taxable. It only decides whether a form is issued. You must report income from the first dollar. Net earnings from self-employment above 400 US dollars generally trigger self-employment tax as well as income tax. On marketplace sales, the marketplace usually collects and pays sales tax under state marketplace facilitator laws; on your own storefront, that job is yours.
United Kingdom. The trading allowance is "a tax exemption of up to £1,000 a year for individuals with trading income." Above 1,000 pounds of gross trading income you must register for Self Assessment, by 5 October after the end of the tax year. Separately, under the digital platform reporting rules, platforms report seller details to HMRC every year by 31 January; your details are not reported if you make fewer than 30 sales of goods in a calendar year and receive less than 2,000 euros (about 1,700 pounds) for them. As HMRC puts it, "platform reporting your details to HMRC does not automatically mean you owe tax". But if you are trading, you owe tax whether or not anyone reports you.
Canada, Australia and the EU. Each has its own registration thresholds, GST or VAT rules and platform reporting regimes, and EU member states differ from one another on VAT registration and on cross-border digital sales. If you sell from or into any of them, get local advice before your first year-end.
One point applies everywhere: your income is the margin you keep, and the gross sales figure overstates it. Marketplace payouts arrive with some fees already taken off and others still to come, and supplier charges hit a different account. Reconcile every month or you will misreport.
Payment risk, chargebacks and account termination
People usually find this category of risk after they have built something.
Refund and chargeback offsets. Amazon's Merch Services Agreement says that if a royalty has been paid and Amazon later issues a refund or credit or receives a chargeback, "we may offset the amount of the Royalty we previously paid you against future Royalties or other amounts that would otherwise be payable to you," or require you to pay it back. It also says that "Amazon may, in its sole discretion, choose to liquidate returned merchandise, in which case no Royalties will be payable."
Limitation period. The same agreement says that "you may not maintain any action or proceeding against us with respect to any report or payment unless you commence that action or suit within 6 months after the date the report or payment was due." Six months is short. If you are not checking your royalty reports, the window can close before you spot a mistake.
Termination. Amazon's agreement is explicit: "We are entitled to terminate this Agreement and access to your Program account at our discretion with or without advance notice to you," and it may suspend you "at our discretion with or without notice." The indemnity provisions survive termination.
Indemnity. Under that agreement you "will indemnify, defend and hold us... harmless from and against any loss, claim, liability, damage, action or cause of action (including reasonable attorneys' fees) that arises from any claim relating to any Content." Add Midjourney's indemnity running the same way, and you end up here: the generator is protected, the marketplace is protected, and you carry the infringement risk for an image neither of you can fully explain.
Working capital. With Printful or Printify you pay for production and shipping when the order comes in and get the marketplace payout later. In a growing month you are financing someone else's fulfilment. That is easy at small scale and turns into a real cash-flow problem right when things start working.
Platform concentration. Every piece of this business sits inside someone else's account: the generator subscription, the marketplace listing, the fulfilment partner, the payout method. One policy change, one suspension or one mistaken IP complaint can wipe out your income with no notice period and, in Amazon's case, no contractual duty to warn you at all. If one of those accounts closed tomorrow, which one would hurt you most? Build your backup there first.
What separates an operation that works from one that doesn't
You now know what the margins look like and what can get you shut down. This next part decides whether you end up with a catalogue that sells or a folder of listings nobody finds.
Given everything above, the version of this tactic that lasts looks specific.
Your human authorship becomes the product. The sellers who survive are the ones whose work cannot be copied by someone typing the same prompt. That means the model is one step in your process, alongside your own drawing, photography, typography, colour work or composition. I say this for practical reasons: it is the only route to a design a competitor cannot regenerate in ninety seconds, and the only route to anything you can register.
Product and niche choice matter more than how many designs you make. The base cost tables above show why. A poster at 11.50 US dollars base and 42 US dollars retail behaves completely differently from a sweatshirt paying a 0.29 US dollar royalty at 35.99 US dollars. Pick the product line first, then design for it.
Technical skill is a real barrier and a real advantage for you. The right resolution for the printable area, the right colour profile, the right bleed and safe margins, files that hold up at 24 by 36 inches instead of only looking fine as a thumbnail. Redbubble lists file quality among its account classification criteria for a reason. Most bulk AI portfolios fail here, so getting this right genuinely sets you apart.
Order samples. Amazon explicitly recommends it. Colour on a screen and colour on matte paper look different, and the reviews you collect from skipping this stay forever.
Make trademark screening a fixed step. Search every phrase, every character reference and every brand-adjacent element in the register for the relevant class before you upload. It is the cheapest risk reduction you have.
Own something. A brand name you have registered, an email list, a storefront. Everything else in this stack is rented.
Owning something is the part that lasts: a registered brand, an email list, a storefront in your own name. If that owned base carries your sales toward the upper half of this range with a margin left over, it is the school trip deposit and new trainers before term starts, from a shop that would survive one marketplace changing its mind. Who are the first twenty people you could invite to that list? Start the email list this week.
A realistic cost and time model
Your startup costs really are low. That is the honest part of the pitch.
- Generation tool: 0 to 60 US dollars a month. Midjourney Basic is 10 US dollars a month; Stealth Mode needs Pro at 60 US dollars a month, or 48 US dollars a month paid annually. Adobe's Firefly-bearing plans differ in price and in whether indemnification applies.
- Fulfilment partner: 0 US dollars on Printful Free or Printify Free. Printful Growth is 24.99 US dollars a month; Printify Premium is 39 US dollars monthly or from 24.99 US dollars monthly billed annually. Neither upgrade is worth buying until the discount you get is bigger than the fee.
- Marketplace: 0.20 US dollars per Etsy listing per four months. Nothing on Amazon Merch or Redbubble.
- Samples: one per product line you plan to sell, at base cost plus shipping.
- Optional and later: 65 US dollars per Copyright Office Standard Application where you have genuine human authorship to register; 350 US dollars per class at the USPTO for a word mark.
So a realistic outlay for your first three months is roughly 100 to 400 US dollars, depending on your tool subscriptions and how many samples you order. That total is my estimate, though every piece of it is sourced above.
Time to first revenue is the number nobody can honestly give you, because it depends entirely on demand in the niche you pick, and because the platforms do not publish how outcomes are spread. Here is what the sourced figures do tell you: on Amazon Merch's Creator rates you need nine sales of a 19.99 US dollar shirt to clear 20 US dollars in royalties. On Redbubble's Standard tier at the default markup you need five sales of a 20 US dollar base product to clear the 10 US dollar payment threshold. On Etsy, at the poster margin modelled above, you would clear roughly 16 US dollars per sale before tax, against a listing fee you pay whether or not anything sells.
Waiting spends the one advantage a small seller has: time for listings to collect views and reviews. Pick one niche you genuinely care about, design five careful pieces this week, and list the best of them. The first sale tells you more than another month of research.
Who should skip this
I will say it plainly, because the sections above make the list obvious.
You, if you need your designs to stay exclusive. You have no copyright in purely AI-generated output in the United States, you cannot register it, you cannot sue over it, and the platforms will not police lookalikes for you. If exclusivity holds up your whole plan, choose a different tactic.
You, if you plan to build a licensing business on top. Licensing needs something to license. You cannot grant a licence over rights you do not hold, and doing it in a written agreement misleads a commercial counterparty.
You, if you intend to describe the work as hand-made or hand-drawn. Etsy requires the opposite disclosure. Consumer protection law requires the opposite in every country listed here. The marketing angle that would make this business easiest is the one closed to you.
You, if bulk uploading is what draws you in. Every platform has already priced bulk uploading in: Etsy through per-listing fees, Redbubble through account tiers that charge high-volume low-effort accounts 50%, Amazon through application gating and upload caps. Volume is the exact strategy the platforms have engineered against.
You, if you cannot absorb an indemnity claim. You have indemnified Amazon. You have indemnified Midjourney. Statutory damages for counterfeit marks start at 1,000 US dollars per mark per goods type and reach 2,000,000 US dollars for wilful use. The chance is low for generic decorative art and rises sharply the moment a prompt names a brand, a character or a person.
You, if you need predictable income within a set period. Platform earnings in this category are extremely lopsided, the platforms do not publish how earnings are spread, and the mean figures you can work out from public filings, around 1,868 US dollars of Etsy GMS per active seller per year before fees and cost of goods, tell you nothing about the median. Please do not treat them as what you should expect.
You, if you have not checked where your own country stands. The US, UK, EU, China, Korea and Canada give materially different answers to the same question. Sections 9(3) and 12(7) of the UK's CDPA appear to offer you more than US law does, but no court has ever applied them to generative AI.
Questions to answer before you spend anything
Nothing you have read so far has cost you money. Settle these before that changes.
- What exactly are you contributing to each design, and would the Copyright Office call it more than prompting? If the answer is no, accept that the work cannot be protected and plan around that instead of hoping.
- Have you read the royalty or margin table for the specific product you plan to sell, at the specific price you plan to charge, in the specific store? Merch's Comfort Colors sweatshirt at 0.29 US dollars sits in the same table as its standard tee at 2.44 US dollars.
- Have you pulled your own region's shipping rates from the fulfilment partner, instead of the ones the site happened to show you?
- Have you searched every phrase and reference in your design against the relevant trademark register, in the relevant class?
- Do you know which disclosures each platform requires, and have you written them into your listing template so you never have to rely on memory?
- If your account were closed tomorrow with no notice (which both Amazon's and Etsy's terms allow), what would you still have?
