01 · Stock

Change a number. Every shop follows.

Set stock once, in Inventory. Every shop that sells the item gets the same number, and only Stockonce sets it.

Stock sync is off until you turn it on. Free sends stock at most once a minute. Live sends it the moment it changes.

04 · Orders

Orders come in. Stock keeps up.

A sold item comes off your stock count when its order is pulled in. A cancellation or full refund puts it back. Pulling the same order again never counts it twice.

Orders are pulled from eBay and WooCommerce on a schedule. Try a sale, then a cancellation or full refund in the demo.
