This chargeback occurs when you ship more units than Amazon originally ordered in the PO.
2 What triggers it & how to prevent it Final composition for this type
overage units100% COGS
✕ What triggers it
Paid quantity is greater than the submitted (ordered) quantity
Submitted, ASN, and invoiced quantities do not match, and paid quantity > submitted quantity
Shipping and invoicing without confirming the PO — since 2025-06-09 this is treated as 100% overage
How can Amazon pay more than it ordered? Amazon Accounts Payable pays the vendor invoice (EDI 810) first; this chargeback is how Amazon then recovers 100% of the cost for the units above the ordered quantity.
How it is calculated : Difference between submitted (ordered) and invoice-paid quantities.
✓ How to prevent it
Confirm and ship the quantity submitted in your PO
If using EDI 855, send confirmations before the ASN, confirming only what you intend to ship
Ensure ASN (EDI 856) quantities match exactly what you confirmed and will ship
Submit one accurate invoice per PO-ASIN (EDI 810 or Vendor Central) — duplicates cause payment delays and chargebacks
Never ship more than the submitted quantity
Returns continue to follow the negotiated vendor returns terms stated in the Vendor Terms and Conditions; Amazon may reach out to negotiate returns on overstock inventory on a case-by-case basis.
