How does Square crosslisting work?
One Square connection syncs your catalog and inventory and powers in-person checkout. ResaleOS keeps Square and your online channels in lockstep so stock is always accurate, online and in store.
ResaleOS connects to Square through a direct API integration. You build each product once in ResaleOS, publish it to Square and every other channel from one catalog, and inventory stays in sync so a sale anywhere ends the listing everywhere.
How Square crosslisting works, step by step
Add your product once in ResaleOS
Create the product in your ResaleOS catalog — photos, price, condition, and details. This is the single source of truth for every channel.
Choose Square (and any other channels)
Select Square as a destination. AI adapts the listing to Square's title limits, category tree, and required fields automatically.
Publish
Hit publish and ResaleOS creates the listing through the API. Edit once in ResaleOS and changes push everywhere.
Sell once, delist everywhere
When the item sells on Square or any other channel, ResaleOS records the sale, decrements stock, and ends the listing everywhere else — so you never oversell.
