Amazon UPS Integration
Nventory bridges Amazon FBM orders and UPS by importing orders into a central dashboard, syncing product data for shipping workflows, and pushing UPS tracking numbers back to Seller Central to protect your seller health score.
Sync Matrix
4 data entities in the sync matrix — 1 bidirectional, 3 one-way. Tap any row for details.
Good to Know
Platform restrictions outside any integration tool's control
Label generation must be done through UPS WorldShip, 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 UPS APIs or Amazon Buy Shipping. Nventory focuses on order and product data sync rather than rate computation.
This integration applies only to Fulfilled by Merchant (FBM) orders. FBA shipments are managed entirely by Amazon.
SurePost is not available on all UPS accounts. You must have an active SurePost agreement before the service is available in your shipping workflow.
Things to Consider
Platform-specific details and how they affect this integration.
Amazon Buy Shipping may offer competitive rates and includes A-to-Z Guarantee protection. Your own UPS negotiated rates may be cheaper at high volume but lack this protection.
Nventory does not manage rate selection or label creation. It imports FBM orders and syncs tracking back to Amazon. The choice between Buy Shipping and your own UPS account is made in your shipping solution.
Who Uses Amazon UPS Integration
Common scenarios for connecting Amazon and UPS.
How It Works
Nventory sits between your platforms and keeps everything in sync.
FBM Order Sync
Amazon FBM orders import to Nventory with ship-by deadlines, promised delivery dates, and customer addresses for centralized management.
Fulfillment Management
Review and prioritize FBM orders by ship-by deadline in Nventory's dashboard. Product data including weights and dimensions is available for your shipping workflow.
Ship via UPS
Create shipments and labels through UPS WorldShip, Amazon Buy Shipping, or your preferred shipping tool using the accurate product data synced by Nventory.
Tracking Upload to Amazon
UPS tracking numbers sync back through Nventory to Amazon Seller Central, confirming on-time delivery and preserving your seller performance rating.
Frequently Asked Questions
No. Nventory does not generate labels directly. It imports Amazon FBM orders, syncs product data, and pushes UPS tracking numbers back to Seller Central. Label creation is handled through UPS WorldShip, Amazon Buy Shipping, or your preferred shipping solution.
Nventory syncs UPS 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 UPS tracking status.
No. Rate calculation is handled by UPS APIs or Amazon Buy Shipping. Nventory focuses on order import, product data sync, and tracking sync rather than rate computation.
After a shipment is created in UPS, Nventory pushes the tracking number to the corresponding Amazon FBM order in Seller Central, confirming shipment and protecting your Valid Tracking Rate. For UPS SurePost shipments that hand off to USPS for last-mile delivery, Amazon still receives the UPS tracking number, though tracking visibility may decrease after the USPS handoff.
No. Nventory does not compare carrier rates or generate labels. Amazon Buy Shipping offers pre-negotiated rates with A-to-Z Guarantee protection, while your own UPS account may offer better pricing at high volume through negotiated UPS Ground or UPS SurePost rates. Nventory ensures accurate product data is synced so whichever rate tool you use has correct weights and dimensions.
Status mismatches often occur because Amazon and UPS use different status code taxonomies — for example, UPS may show 'Out for Delivery' while Amazon still displays 'Shipped.' For multi-package shipments, verify that all tracking numbers in the order are updating, as Amazon may only display the status of the primary tracking number. Also check for delivery confirmation discrepancies where UPS shows 'Delivered' but Amazon hasn't updated, which can happen when UPS delivery scans are delayed or when the recipient address doesn't match Amazon's expected format.
