AI Marketplace Listing
Your master catalog adapted into ready-to-publish listings for the third-party marketplaces you sell on.
Selling on several marketplaces means rewriting the same product data again and again, each time in a different format with different rules. This build takes your master catalog and adapts it into listings that match each marketplace's own field structure and category rules. Every listing is approved before it is published, so your products appear correctly everywhere you sell.
- Master catalog adapted into marketplace-ready listings
- Each marketplace's fields and category rules followed
- Every listing approved before it is published

What it is
AI Marketplace Listing adapts your master product catalog into listings for the marketplaces you sell on. These include Walmart, eBay, Etsy, TikTok Shop and Amazon. Each listing follows that marketplace's own fields and category rules. Output goes to the one destination you choose. You approve every listing before publishing.
Why businesses buy it
Marketplaces can open up large new audiences, but poorly formatted listings get suppressed, rejected or simply ignored. Reformatting by hand for each channel is slow and error-prone, which holds back expansion. This build turns one master catalog into listings that fit each marketplace properly, so you can sell in more places without more admin. The written scope sets out the marketplaces covered, the approval step and the output destination before you order.
Problems this solves
The same product text gets pasted into every marketplace
AI Marketplace Listing adapts your master catalog into listings shaped for each marketplace you sell on. It matches each one's field structure and category rules.
Listings get rejected for breaking marketplace category rules
Each listing is formatted to the marketplace's own fields and category rules before you see it. That can mean fewer listings bounced back for fixes after you submit them.
Keeping listings in line with the master catalog is tedious
Listings start from your master catalog, in your brand voice from up to 20 reference examples. Output goes to one destination, and you approve every listing before publishing.
A good fit if
You sell the same products across more than one marketplace and currently reformat each listing by hand.
Different marketplaces reject or bury your listings because the category, field structure or title format does not match what they expect.
You maintain one master catalog as the source of truth and want marketplace listings generated from it, not edited separately.
You want a reviewable batch of adapted listings delivered to one destination, not a live tool you configure per marketplace yourself.
Not the right fit if
You sell mainly on Amazon and want listings tuned to Amazon's own search and style rules alone. See AI Amazon Listing Optimization, built for Amazon only. This product treats Amazon as one format among several.
You are not adapting for other marketplaces yet, and just need better descriptions on your own store first. See AI Product Description Engine built for first-draft catalog copy.
Your listings read fine but do not rank inside your own store's search. See AI Product SEO, which optimizes titles, meta and schema for on-site and organic search.
You need more than 3 output formats or more than one destination system, for example separate feeds to five marketplaces at once. Add a note at checkout for a Change Quote, or start from our Custom AI enquiry form.
How it works
- You hand over your brand guidelines, the product or topic list to start with, and access to the destination for the finished listings.
- The engine reads your master catalog and maps each product's fields against the category and field structure of the marketplaces you named.
- It drafts listings in up to 3 output formats, matched to your 10 to 20 reference examples so tone stays consistent across every marketplace.
- 25 sample outputs are reviewed and approved by you before the full run, so formatting issues are caught early, not after publishing.
- Approved listings are delivered to the single destination you chose, ready for your team to publish or feed into your marketplace channel.
- Anything that does not map cleanly to a marketplace's category structure is flagged rather than force-fit into the wrong place.
What you provide within 72 hours
Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.
- Your brand guidelines and tone-of-voice examples, so listings still sound like your store across every marketplace.
- Ten to twenty reference examples of listings you already like, from your store or another marketplace.
- Access to the destination for the finished listings, whether that is your store, a CMS or a shared drive.
- The product or topic list you want adapted first, plus which marketplaces they are going to.
- The name of the person who reviews and approves the sample outputs before the full run.
- Admin access and API keys for every connected system, shared by adding our team as a user or creating a key you control, never by email.
- Your business information (company basics, hours and brand voice), shared during intake.
- One decision-maker on your side who can sign off during the build.
- An API key for your own AI model account (for example OpenAI or Google Gemini), created for this build with a spending limit.
The 72-hour rule. Send everything on your checklist, including access, within 72 hours of ordering so your build starts on time.

Expected benefits and how to measure them
- Can make it quicker to list products on a new marketplace.
- Helps listings follow each marketplace's rules from the start.
- Time to list a product on a marketplace
- Time a sample of listings before launch and a sample after.
- Rejected or suppressed listings
- Count them in each marketplace's seller dashboard for the month before and the month after.
- Marketplace sales per listing
- Compare sales in each marketplace's reports for adapted listings over the two months before and after.
Before you start: Record how long listing a product takes and how many listings were rejected last month. Note which marketplaces you sell on.
These are things to track, not promised results. Outcomes depend on your data, your team and your market.
Running costs
The build price is one-time. Running the engine is billed to your own accounts, mostly AI model usage: typically $20 to $150 a month, depending on how many listings you generate.
AI usage during the build and test phase is billed the same way, so your AI provider relationship stays in your own name throughout.

How maintenance worksHow this compares
| Do it yourself with a SaaS tool | Hire a custom agency | Upmark Labs | |
|---|---|---|---|
| Price | A multichannel listing tool charges a monthly fee per connected marketplace | A listings agency quotes per marketplace, per catalog | Ours is one fixed price, shown before you buy |
| Scope | A listing tool syncs the same text everywhere, formatting issues included | An agency agrees scope during the project | Ours is written on the Scope Card before purchase |
| Field mapping | Most tools push raw fields without adapting to each marketplace's rules | An agency build depends on what was agreed | Ours maps each product to the target marketplace's own structure |
| Delivery | A listing tool connects in a day but formatting stays generic | An agency usually takes several weeks, set per project | Ours has a fixed delivery time shown before you buy, with faster options |
| Review step | Most tools publish immediately with no sample stage | An agency build depends on what was agreed | Ours reviews 25 sample outputs with you before the full batch |
Questions about this product
What does AI Marketplace Listing cost?
Each delivery speed has one fixed price. The price panel shows standard, express and rush side by side before you pay, and the cart confirms your delivery date. Running costs of roughly $20 to $150 a month are separate and paid to your own providers.
What does AI Marketplace Listing cost to run each month?
Typically $20 to $150 a month in AI model usage, depending on how many listings you generate in a given month. There is no separate platform fee from us. Optional monthly maintenance for ongoing format changes is priced on this page.
Does it push listings directly to the marketplace?
It delivers finished, marketplace-formatted listings to the single destination you choose, such as your store, a CMS or a shared drive. Publishing to the marketplace itself happens through your own marketplace account, so you control exactly what goes live and when.
Which marketplaces can it adapt listings for?
Any marketplace with a documented listing structure, such as Walmart, eBay, Etsy, TikTok Shop, Google Shopping or Amazon. You choose up to three formats during the build. If Amazon is your main channel, AI Amazon Listing Optimization goes deeper on Amazon's own search rules and is the better fit.
Will the tone stay consistent across different marketplaces?
Yes. The engine learns from the 10 to 20 reference examples you approve before the full run, and 25 sample outputs are reviewed with you first, so listings read like your brand on every marketplace rather than drifting between formats.
What happens once AI Marketplace Listing's 30 days of support end?
You can move to monthly maintenance, which includes monitoring, fixes and a monthly allowance of change hours. It is optional, bills monthly and can be cancelled in any month. Without it, the pipeline keeps running; you simply lose included changes.
Do I own the adapted listings it produces?
Yes. Every listing delivered to your destination is yours outright, to edit, publish or reuse on any marketplace you choose, this run or a later one. Nothing about ongoing use depends on us staying involved after the 30 days of included support end.
