Amazon and BigCommerce sync questions

How does syncing Amazon and BigCommerce work?

ZapInventory connects both accounts and keeps one stock figure per product. A sale on Amazon or BigCommerce updates the other within seconds, so the same unit is never sold twice.

What happens if an item sells on Amazon and BigCommerce at the same time?

Conflict resolution favours the most recent confirmed order and writes the new quantity to both channels, so stock never goes negative.

Do my Amazon and BigCommerce products need matching SKUs?

Matching SKUs make setup instant, but ZapInventory can also map products manually, so mismatched Amazon and BigCommerce catalogues still sync correctly.

How often does Amazon and BigCommerce sync?

Continuously. ZapInventory polls both channels and writes stock changes in real time rather than on a fixed schedule, so availability is always current.
