Thousands of SKUs, synced across every channel.
Drop shipping is a data problem: prices and stock change constantly, and getting it wrong means cancellations, bad reviews, and suspensions. ResaleOS keeps every listing on every marketplace in sync with your supplier feed 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.

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.
Reprice the catalog, not the products.
Filter to the supplier, the brand or the category, change price, tags or channels across the lot, and push it all out in one run.

Narrow to a brand, a category, a location or an intake, and act on the whole set at once.
Take 20% off, round to the nearest dollar, or set a flat price across everything you selected.
Category, tags, condition, location, status and channel selection, all editable in one pass.
Whatever you changed syncs to the channels those products are live on.
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.

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.
