Amazon ShipStation Integration
Nventory connects Amazon Seller Central to ShipStation for merchant-fulfilled order management. MFN orders sync into Nventory, feed into ShipStation for batch label printing and carrier automation, and tracking pushes back to Amazon to maintain Valid Tracking Rate compliance.

Good to Know
Platform restrictions outside any integration tool's control
Fulfillment by Amazon orders are handled by Amazon's warehouses. This integration covers merchant-fulfilled (MFN/FBM) orders only.
Batch label creation happens in ShipStation. Nventory syncs order data and pushes tracking back to Amazon.
Orders route through ShipStation rather than Amazon Buy Shipping. VTR compliance is maintained through proper carrier code mapping in Nventory.
Things to Consider
Platform-specific details and how they affect this integration.
Amazon requires Valid Tracking Rate above 95% for MFN sellers. Tracking uploaded from third-party tools must use Amazon-recognized carrier codes.
Nventory maps ShipStation carrier information to Amazon-recognized carrier codes when pushing tracking numbers. This ensures every shipment counts toward your VTR metric even when labels are created outside of Amazon Buy Shipping.
