Ruit is a multichannel listing and inventory platform built for second-hand businesses. Professional resellers, vintage shops and small warehouses sell the same stock across several marketplaces at once, and they lose most of their time to the same three chores: retyping every listing on every platform, keeping stock in sync so nothing sells twice, and answering buyers scattered across half a dozen inboxes. Ruit removes all three.

You upload your catalog once. From a single product sheet, Ruit publishes to Wallapop, Vinted, eBay, Shopify, WooCommerce, PrestaShop and TodoColeccion, adapting titles, categories and attributes to what each marketplace expects. Publishing can be done in bulk or scheduled, so a whole batch of items goes live at the hour your buyers are actually browsing.

Once an item is live, Ruit keeps it that way. Stock syncs in real time across every connected channel, so a sale on Vinted removes the item from eBay before a second buyer can reach it. Listings are renewed automatically to stay near the top of marketplace search results, and items can be withdrawn and republished on a schedule without any manual work. Every message and offer from Wallapop, Vinted and eBay arrives in one unified inbox, so a seller answers buyers from a single screen instead of juggling three apps and a browser full of tabs.

Ruit also handles the parts of resale that usually happen in a spreadsheet. AI-assisted photo editing cleans up product images. Analytics show what sells, where and at what margin. A built-in price comparator and full price history let sellers research what similar items actually sold for before deciding what to charge, and instant alerts flag opportunities as they appear. Transaction history keeps sales from every channel in one ledger. Ruit works on the web, as a Chrome extension, and as native apps for iOS and Android. It is available in eight languages: Spanish, English, French, Italian, Portuguese, German, Polish and Dutch.
