Buy and Sell Digital Products in One Marketplace

Digital products are the one category of goods where a single copy can be sold a hundred times without a warehouse, a courier or a stock order. That is why the phrase buy and sell digital products covers so much ground: it includes the person buying a two-dollar prompt to finish a client job this afternoon, and the person listing their first ebook hoping it earns while they sleep.

This page covers both sides of that transaction as they actually work on PromptBase.art. What counts as a digital product here, how a listing is judged before anyone pays for it, how the economics look once the platform takes its share, how and when money is paid out, and the legal reality around reselling somebody else’s file — which is where most beginners get into trouble.

The short version: you can start selling today with no inventory and no listing fee, the payout threshold is fifty dollars, and the platform pays seventy percent of every sale to the creator. The longer version — pricing, licences, what buyers actually check before paying — is below.

What counts as a digital product on this marketplace

There are three product types here, and each is published through its own upload flow. AI prompts cover image, video, text and system prompts for tools such as Midjourney, ChatGPT, Claude, Sora, Veo, Kling and Runway; they are bought with credits, where one hundred credits equals one US dollar. Ebooks are complete PDF guides priced in dollars, and every one of them can be previewed free before purchase. Apps are Android builds sold with a source archive and screenshots, priced by the seller.

The catalogue today holds ninety-nine published prompts, twenty-four published ebooks and five published app listings. Prompts run from free to two hundred and fifty credits, ebooks from seven to nine dollars, and apps between five and seventeen dollars. Nothing on the marketplace is a subscription, so a buyer pays once and keeps the file.

How buying works, and what to check before you pay

Buying is deliberately short: open the listing, read the samples, pay by card or crypto, and the file unlocks in your account. Prompts unlock their full text on the page, ebooks download as a PDF, and app listings expose the screenshots, the version and the archive the seller uploaded. Purchases stay in your account, so re-downloading something bought months ago does not require an email to support.

The check that matters before you pay is the sample. On a prompt listing, look for several outputs that share lighting, framing and palette — that consistency is what separates a prompt with real structure from one that got lucky once. On an ebook, use the free preview pages to judge the actual writing and the layout rather than the cover. On an app, read the version number and the feature list and confirm the platform matches your phone.

Selling: what a listing needs to go live

Listing is free and there is no application review queue to wait in for prompts. A prompt listing needs the prompt text, the model it was written for, a category, a price in credits and samples generated from that exact prompt. An ebook listing needs a text-layer PDF, a cover image, a title, a description and a price. An app listing needs the build, its source archive, screenshots and the licence terms you are selling under.

Ebooks and apps are reviewed by a human before they appear in the store, which is deliberate: the store’s value depends on a buyer being able to trust that a listing is what it says. Prompts are checked for real samples, a named model and a matching category, and duplicate or near-identical listings are removed rather than left to age.

The economics: 70% to the creator, with the arithmetic shown

Every sale pays seventy percent to the creator, with no sliding scale and no penalty for being new. A two-dollar prompt pays one dollar forty. A nine-dollar ebook pays six dollars thirty. A fifteen-dollar app pays ten dollars fifty. Because there is no listing fee and no monthly plan, the only thing a failed listing costs you is the afternoon you spent writing it.

That share is unusually high for a marketplace that also handles checkout, delivery, refunds and support. Amazon pays seventy percent on ebooks only inside a narrow price band and thirty-five percent outside it; template marketplaces typically keep a similar or larger cut and charge for the privilege of being listed. Here the trade is simple: the platform takes thirty percent and does not charge you to be present.

Getting paid: $50 threshold, PayPal or USDT

Earnings accumulate per listing in the creator dashboard, so you can see which products convert and which get views without sales. When the balance reaches the fifty-dollar minimum you request a payout and choose the method: PayPal, or USDT on the BEP20 network. The request shows in your dashboard with its status until it is settled.

Two honest notes. First, the threshold means a marketplace cannot send five dollars across international borders profitably — accumulate, then withdraw. Second, payment details have to match the account holder; a payout sent to somebody else’s PayPal is the most common reason a settlement stalls, and it is not something support can override on request.

Can you resell someone else’s digital product?

This is the question behind most of the search volume for buy and sell digital products, and the answer is almost always no. Buying an ebook, a prompt or an app gives you a licence to use the file — not the right to redistribute it as your own product. Reselling a copy you did not create is copyright infringement, and on this marketplace duplicate uploads are compared at file level and rejected.

What you can legitimately do is resell a product you own the rights to, or sell something you built using a purchased product as an ingredient, where the licence allows it. A prompt pack bought here can be used to produce client work; the prompt text itself cannot be republished as your own listing. If you want the full margin, the honest path is to create the product — which is exactly what the next page covers.

What actually sells, and what sits unread

Products sell when they answer a job the buyer does repeatedly. A prompt for weekly product photography, an ebook on a specific regulatory or technical problem, an app that removes one recurring annoyance — those convert because the buyer already knows they need the outcome. Generic inspiration rarely sells, because the buyer has no deadline attached to it.

Narrow also wins on discovery. “A cinematic film still” competes with thousands of free alternatives; “matte ceramic product shot on a warm studio sweep, three aspect ratios” is what somebody types when they have that exact shoot tomorrow. Write the listing title in the buyer’s words, put the deliverable in the first line of the description, and put the evidence in the samples.

Starting today, in the right order

Pick one product type — do not launch an ebook, a prompt pack and an app in the same week. Create one item you can defend, price it in the lower half of the range while you have no reviews, and publish it with the samples that show it working. Then watch the dashboard for views: a listing with traffic and no sales is a sample or description problem, not a pricing problem, and it is fixable in an afternoon.

Once one listing converts, add two or three products in the same niche rather than one product in three niches. A buyer who liked your first item is the warmest audience you will ever have, and each new listing is another entrance from search. That is the whole growth model here, and it does not require advertising spend.

Step-by-step

1. Choose the product type: Prompts for credits-based buyers, ebooks for readers who want a complete guide, apps for buyers who want a working tool. Pick the one you can actually produce this week.
2. Create the deliverable: Write the prompt text, finish the PDF, or package the app build with its source archive. The deliverable is the product — samples only demonstrate it.
3. Produce real samples: For prompts, generate several outputs from the exact text being sold. For ebooks, use the first pages as the preview. For apps, capture real screenshots of the shipped build.
4. List it free: Publish from the Sell page (prompts), the ebook upload page or the app upload page. There is no listing fee and no subscription.
5. Price against reuse: Set the price in credits for prompts (100 credits = $1) or in dollars for ebooks and apps. Price what the buyer will use it for, not how long it took you.
6. Withdraw from $50: Earnings accumulate per listing in the dashboard. At fifty dollars, request a payout to PayPal or USDT (BEP20); payouts below the threshold stay as balance.

Frequently asked questions

What digital products can I sell here?

Three types: AI prompts (image, video, text, system, Shorts scripts), complete ebooks as PDF, and Android apps with their source archive. Each has its own upload page and its own pricing unit.

Does it cost anything to list a product?

No. Listing is free across all three stores, there is no seller subscription and no minimum catalogue size. The platform earns only when you sell, by keeping 30% of the sale.

How much do I keep per sale?

Seventy percent. A $2 prompt pays $1.40, a $9 ebook pays $6.30, a $15 app pays $10.50. No price-band rules and no sliding scale.

When and how do I get paid?

Earnings appear per listing in the creator dashboard. At the $50 minimum you request a payout and choose PayPal or USDT on BEP20; the request shows its status until settled.

Can I resell a digital product I bought?

No. A purchase gives you a licence to use the file, not to redistribute it. Reselling a copy you did not create is infringement, and duplicate uploads are rejected at file level.

Do buyers need an account?

An account is what stores the purchase and its download, so yes for buying — but nothing is gated behind a subscription. Sellers log in to publish and to see earnings.

How are payments taken from buyers?

Card (Visa and Mastercard) or cryptocurrency at checkout, one product at a time at its listed price. Prompts can also be bought with credits, where 100 credits equals one dollar.

What is the fastest product to create for a first sale?

A single well-documented prompt in a category you already work in, with four consistent samples. It is one afternoon of work, it lists instantly, and it tells you whether your niche converts before you invest in a book or an app.
