As of July 28, 2026, Amazon lets sellers link their own carrier accounts, USPS, UPS Roadie, UPS Mail Innovations, OnTrac, and DHL eCommerce, directly into Buy Shipping, keeping negotiated rates and Amazon delivery protections at the same time.
What Linking a Carrier Account to Buy Shipping Actually Does
Linking applies your own negotiated rate when you purchase a label through Amazon Buy Shipping instead of Amazon standard published rate. You are still charged by the carrier directly. Five carriers are supported: USPS, UPS Roadie, UPS Mail Innovations, OnTrac, and DHL eCommerce.
The Protections You Gain That Direct Carrier Booking Does Not Offer
Buying labels directly from a carrier website has always meant giving up Amazon Buy Shipping protections: on-time delivery rate protection and refunds for delivery-related claims. Linking now gets your negotiated rate the same protections.
How Linking Actually Works, Step by Step
Go to Manage your carrier accounts to link. You need your existing carrier credentials and rate agreement already in place. You can link multiple accounts and assign different accounts to different ship-from locations. Labels purchased count toward your existing minimum volume commitment with that carrier.
Where You Access Buy Shipping Once Linked
Purchase labels through Manage Orders, the Shipping API, Veeqo, or other multi-channel integrators, the same tools you likely already use.
Who Should Actually Make the Switch
Most valuable for self-ship sellers with an existing negotiated rate who have been buying labels outside Amazon specifically to preserve it. Confirm with your carrier representative that volume commitment tracking works as described.
Explore our Amazon Fee Calculator to model how a negotiated rate changes your net margin.
A Worked Example: What This Could Mean for Your Numbers
The actual savings depend on your specific negotiated rate versus Amazon standard rate. Suppose you ship 500 packages a month through USPS at a negotiated rate 12 percent below Amazon standard Buy Shipping rate. If your average label cost at standard rate is $6.50, your negotiated rate lands around $5.72. Across 500 monthly shipments, that gap is roughly $390 a month, or close to $4,700 annually, previously only capturable by buying labels outside Amazon and forfeiting Buy Shipping protections.
The more important number is what this does to per-unit contribution margin. A few hundred dollars a month in shipping savings, applied across a catalog running thin margins, can be the difference between a marginally profitable SKU and one not worth carrying. Run your own numbers using your actual negotiated rate before assuming the update is or is not worth the setup time.
Before committing full shipment volume, a reasonable test: link the account, run a subset of shipments through the linked rate, and confirm the charge on your carrier invoice matches what you expected before scaling to your entire operation.
What This Signals About Amazon Fulfillment Strategy
This update makes self-fulfillment through Buy Shipping more competitive with independent carrier relationships rather than pushing sellers toward FBA.
