What a Wix sale writes
One invoice per order, and a count that follows the shop.
When a Wix order lands, we write it into QuickBooks as its own invoice, a line per item with the number sold and the price paid, tied to whichever QuickBooks item shares the SKU. The quantity on hand moves with it, so the books’ count follows what actually sold rather than being typed in at quarter-end.
The quantity in QuickBooks is a bookkeeping figure no shopper ever sees. When you’re reconciling, Wix holds what the shop shows and QuickBooks holds what the books say, and we correct the second from the first.
