Shopify and Amazon sync questions
How does syncing Shopify and Amazon work?
ZapInventory connects both accounts and keeps one stock figure per product. A sale on Shopify or Amazon updates the other within seconds, so the same unit is never sold twice.
What happens if an item sells on Shopify and Amazon 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 Shopify and Amazon products need matching SKUs?
Matching SKUs make setup instant, but ZapInventory can also map products manually, so mismatched Shopify and Amazon catalogues still sync correctly.
How often does Shopify and Amazon sync?
Continuously. ZapInventory polls both channels and writes stock changes in real time rather than on a fixed schedule, so availability is always current.
