The fastest way to be everywhere at once.
Cross-posting the same item to five marketplaces by hand — then racing to delist it when it sells — is where resellers lose their evenings. ResaleOS does it in one click, adapts each listing with AI, and keeps everything in sync automatically.
List it once and it goes everywhere.
Pick the products, tick the channels, hit publish. eBay, Etsy, Shopify, Poshmark, Depop, Facebook and the rest are handled in the background, each getting a listing shaped the way that platform wants it.

ChairishQueuedSelect the products, tick the channels, hit publish. Everything after that happens in the background.
Your category is mapped to each marketplace’s own taxonomy, and the required fields are answered from the product.
Rewritten to each platform’s length limit, in the words buyers on that platform actually search for.
Anything that does not take is retried, and whatever is still wrong is written on the product in plain words.
Nobody gets to buy it twice.
The moment the last one sells — at your counter or on any channel — the listing comes down everywhere else. Refund it and the listings that were pulled go back up on their own.

eBaywhere it soldLiveEtsyLiveShopifyLivePoshmarkLiveStorefrontLiveThe moment the last one sells, the listing comes down on every other channel it was live on.
Restock a returned item and the listings that were pulled go back up automatically.
eBay, Etsy, Shopify, Square, Wix, WooCommerce and Kashew tell us the moment an order lands; the rest are checked on a schedule.
If a channel suddenly claims half your catalog has vanished, we do not believe it and nothing is delisted.
Marketplace orders land as real sales.
Line items, tax, shipping and the platform’s cut arrive in your books as a sale you can report on — with the stock deducted once and the seller’s share worked out the same moment.

Line items, tax, shipping and the platform’s cut land in your books as a sale you can report on.
If the item was on consignment, the share is calculated and the balance moves the same moment.
Deducted at the location it sold from, and matched to the order so the same sale can never count twice.
The order is waiting to be picked, labelled and shipped alongside everything else you owe a buyer.
Rates, labels, and the things that need two people.
Compare USPS, UPS and FedEx side by side on the real weight and dimensions, buy the label, and quote a two-person crew for the pieces that were never going in a box.
No rate selected
Pick a service to continue
Every service priced off the weight and dimensions on the product, cheapest and fastest called out.
Buy the label, print it, and the tracking is on the sale — with batch printing for a whole day of orders.
Furniture and oversized pieces quoted by crews who carry them inside, with a date picked before anyone pays.
Scans flow back onto the order, so you know it moved without opening the carrier’s website.
One system. No add-ons. No per-channel fees.
From the sales counter to the shipping label, the tools you actually use every day are built in — not bolted on.
