Amazon FedEx Integration
Nventory bridges Amazon FBM orders and FedEx by importing orders into a central dashboard, syncing product data for shipping workflows, and pushing FedEx tracking numbers back to Seller Central to protect your seller health score.

Good to Know
Platform restrictions outside any integration tool's control
Label generation must be done through FedEx Ship Manager, Amazon Buy Shipping, or a dedicated shipping label solution. Nventory syncs order data and tracking info but does not create labels directly.
Rate calculation requires direct integration with FedEx APIs or Amazon Buy Shipping. Nventory focuses on order and product data sync rather than rate computation.
Orders fulfilled by Amazon (FBA) are shipped from Amazon warehouses using Amazon's own carrier network. This integration only applies to Fulfilled by Merchant (FBM) orders.
Amazon Buy Shipping offers its own negotiated carrier rates. You can choose between Buy Shipping rates and your own FedEx account rates, but A-to-Z Guarantee protection may vary.
Things to Consider
Platform-specific details and how they affect this integration.
Using Amazon's Buy Shipping API provides A-to-Z Guarantee protection on shipping claims. Labels generated outside Buy Shipping may not receive this protection.
Nventory does not generate labels directly. It imports FBM orders and syncs tracking back to Amazon. Label creation through Buy Shipping or your own FedEx account is handled by your preferred shipping solution.

Frequently Asked Questions
No. Nventory does not generate labels directly. It imports Amazon FBM orders, syncs product data, and pushes FedEx tracking numbers back to Seller Central. Label creation is handled through FedEx Ship Manager, Amazon Buy Shipping, or your preferred shipping solution.
Nventory syncs FedEx tracking numbers back to Amazon Seller Central after shipments are created, helping maintain your Valid Tracking Rate. It also imports orders with ship-by deadlines visible for prioritization.
Yes. Nventory imports orders from Amazon, Shopify, and other channels into a unified dashboard, giving you visibility into all orders and their FedEx tracking status.
Nventory imports orders with ship-by dates visible in the dashboard, helping you prioritize fulfillment. The actual label creation and shipment confirmation happen through your shipping tool.
After a shipment is created in FedEx, Nventory picks up the tracking number and pushes it to the corresponding Amazon FBM order in Seller Central. This confirms the shipment and protects your Valid Tracking Rate. For FedEx SmartPost shipments that hand off to USPS for final delivery, Amazon receives the FedEx tracking number, though scan events may become less granular after the USPS handoff.
No. Nventory does not perform rate shopping or compare carrier services. To compare FedEx Ground, FedEx Home Delivery, and FedEx SmartPost rates for Amazon orders, use Amazon Buy Shipping or a multi-carrier shipping tool. Nventory ensures accurate product weights and dimensions are synced so whichever rate tool you use has correct data for service-level comparisons.
First verify that the carrier name submitted to Amazon matches their accepted carrier list exactly — Amazon requires 'FedEx' rather than variations like 'Federal Express' or 'FEDEX'. Confirm that the tracking number format is valid for the FedEx service used, as Amazon validates tracking numbers and rejects malformed ones. Also check whether you are using Amazon's Buy Shipping API, which has stricter requirements for carrier and tracking data than manual tracking uploads.
