About ResaleOS – Marketplace Connector
Start selling on all your favourite resale marketplaces from one place.
ResaleOS is the operating system for resellers: list once and it goes everywhere,
sell once and everywhere else updates. This extension is how you get started. Click
Connect in ResaleOS and it links the marketplace accounts you're already using in
this browser. No re-typing anything, no starting from scratch.
GET SET UP IN UNDER A MINUTE
1. Add the extension.
2. Open ResaleOS — it recognises you automatically.
3. Settings → Sales channels → Connect. That's it, you're live.
WHAT YOU GET
• Crosslist to every marketplace in one go, from one form
• Import the listings you already have, so you start with your whole inventory
• Keep prices, photos and details in sync everywhere
• Sold on one? It comes down on the others automatically
• See sales, fees and profit across every channel in one dashboard
BUILT FOR RESELLERS
Whether you run a closet, a booth, a consignment shop or a full storefront,
ResaleOS handles the busywork so you can get back to sourcing and selling.
PRIVACY, PLAINLY
The extension only ever connects the marketplaces you pick. It reads a marketplace
session when you click Connect, and afterwards only to keep that connection signed
in when the marketplace changes your login. It can't see your other tabs, your
browsing history, or the contents of any page you visit, and it never touches your
ResaleOS password. Full details:
