The most complete crosslisting platform
Most crosslisting tools cover a handful of marketplaces and leave you to reconcile stock by hand. ResaleOS connects to 29+ marketplaces and e-commerce platforms from one catalog — then keeps every listing and every unit of inventory in sync so a sale anywhere ends the listing everywhere.
ResaleOS is a single system for listing, inventory, and sales across 29+ channels. You add a product once, pick where it should go, and hit publish. AI adapts each listing to the destination, ResaleOS publishes it — through an official API where one exists, or a secure browser session where one does not — and inventory stays synced so you never sell the same item twice.
Every place you sell, in one place

E-commerce Platform
One workflow, no matter the channel
The hard part of selling on many marketplaces is not the first listing — it is everything after: keeping titles and prices adapted to each platform, remembering where an item is live, and pulling it down the instant it sells so you do not sell it twice. ResaleOS handles all of it from a single catalog.
Publish once
Add a product, pick your channels, hit publish. AI writes each listing to fit the destination's title limits, category tree, and required fields.
Stay in sync
Edit once and push changes everywhere. Inventory is tracked centrally, so stock counts stay accurate across every channel and in-person sales.
Never oversell
When an item sells anywhere, ResaleOS records the sale and delists it from every other channel automatically — no double-sales, no manual cleanup.

Frequently asked questions
How many marketplaces does ResaleOS crosslist to?
ResaleOS connects to 29+ selling destinations — general marketplaces (eBay, Etsy, Mercari, Bonanza), fashion and luxury resale (Poshmark, Depop, Vinted, Vestiaire Collective, The RealReal), sneakers and streetwear (StockX, GOAT), refurbished electronics (Back Market, Reebelo), home and furniture (Chairish, Ruby Lane, Houzz), local marketplaces (Facebook Marketplace, Craigslist), plus e-commerce platforms (Shopify, WooCommerce, Wix, Squarespace) and social commerce (Pinterest, Google, Meta Shops). New integrations are added continuously.
What does crosslisting actually do?
Crosslisting lets you list one product to many marketplaces at once from a single catalog. ResaleOS adapts each listing to the destination — titles, descriptions, categories, item specifics, and pricing — publishes it, and keeps inventory in sync so that when an item sells anywhere, it is automatically delisted everywhere else. You never re-type a listing and never oversell.
Does it connect through official APIs or browser automation?
Both. Where a marketplace offers an official API (eBay, Etsy, Shopify, Mercari, Vinted Pro, StockX, Back Market, Vestiaire Collective, Houzz and more) ResaleOS uses it. Where a marketplace has no API (Poshmark, Depop, Facebook Marketplace, Craigslist, Whatnot, Chairish, Ruby Lane) ResaleOS publishes through a secure, signed-in browser session — so you get one consistent workflow across every channel.
How does inventory stay in sync across all those channels?
ResaleOS is the single source of truth for your stock. When an item sells on any connected channel — or in person through Point of Sale — the sale is recorded, stock is decremented, and the listing is ended on every other channel automatically. That is what prevents double-sales when you list the same item in a dozen places.
Do I need a separate tool for each marketplace?
No — that is the point. Instead of juggling a listing tool per marketplace plus a spreadsheet for stock, ResaleOS is one catalog, one publish button, and one inventory system covering every channel, plus AI listing generation, shipping labels, a pricing engine, and Point of Sale in the same place.
