Your products, listed right on every marketplace.

Keylist takes your supplier data and turns it into complete listings for eMAG, Trendyol and Europe's marketplaces. It keeps an eye on stock, prices, ads and invoices, and you just review and approve.

Launching soon. Our first sellers work with us directly.

Create listings for the products in the new supplier file.

All the work between supplier and marketplace

The things you do today by hand, in spreadsheets or one platform at a time.

Complete listings from incomplete data

Start from a product name, a code or a supplier file. Keylist fills in the title, description and the attributes each category requires.

Listing tools

Imports and feeds without spreadsheets

CSV and Excel files and XML feeds, converted to each platform's format, with no more matching columns by hand.

Import tools

Stock and prices in sync

Spot out-of-stock offers, misaligned prices and lost buy boxes before they cost you orders.

Stock and price tools

Orders, shipping labels and invoices

Late orders, shipping labels prepared from order data, and invoices issued and attached automatically.

Order tools

Campaigns and reconciliation

The right products for each campaign, simulated against your margin, and marketplace payouts matched to your orders.

Campaign tools

Analytics and ROAS

See what every channel really earns

Revenue, ad spend, ROAS and net margin for all your marketplaces in one place. Keylist tells you which campaigns pay off and which ones eat your margin.

Up and running in three steps

No developer, and no change to the way you work.

  1. Connect your sources

    Supplier files and feeds, plus your marketplace and invoicing accounts.

  2. Ask for what you need

    In plain words: “create the listings”, “which offers are out of stock”, “which orders have no invoice”.

  3. Review and approve

    See every change before it's applied. Nothing goes to a marketplace without your say-so.

You stay in control

Keylist proposes, you decide. Every action that changes something in your accounts waits for your approval and is kept in the log.

How we protect your accounts
  • Approval before any changePrices, stock, listings, invoices: you see exactly what will change before you approve.
  • Protection rulesSet limits such as minimum margin or maximum price drop. Anything beyond them is blocked automatically.
  • Full activity logEvery action is recorded: who asked for it, what changed and when.
  • Encrypted keysYour marketplace credentials are encrypted and never sent to the AI model.

Your activity log

Always know what was checked and what was changed.

“I run 5 companies selling on eMAG, Trendyol and marketplaces across Europe. I built Keylist because I was tired of doing the same manual work every single day.”

Founder of KeylistMarketplace seller

Built by a seller, for sellers

Keylist wasn't dreamed up in an office. It comes from day-to-day work on marketplaces, through every stage:

  • Manual publishing
  • Product feeds
  • CSV imports
  • Price comparison sites
  • BaseLinker and easySales
  • Invoice reconciliation
  • AI assistants

Frequently asked questions

When does Keylist launch?

Keylist is in development, and we're working with a small group of sellers ahead of the public launch. Sign up for early access and you'll hear from us first.

How much does it cost?

Pricing will be announced before launch. Sellers on the early access list will be the first to know.

Can Keylist change anything without my approval?

No. Every change to your accounts (price, stock, listing, invoice) is shown to you first and applied only after you approve it. You can also set rules that automatically block changes that are too large.

Why does Keylist need my marketplace API keys?

To read your offers and orders and, once you approve, to send the changes. Keys are stored encrypted, never reach the AI model, and you can delete them at any time.

Do I need a developer?

No. You connect your accounts from the interface and write your requests in plain language, like a conversation.

Can I use it alongside BaseLinker or easySales?

Yes, that's the idea. Keylist prepares, checks and fixes your data, and your integrator can stay the one that publishes, if you prefer.

What happens to my data if I leave?

You can ask us to delete your account and all your data, including your access keys. The details are in our privacy policy.
