What are Amazon Vendor Central Chargebacks & Shortage Claims?▼
Vendor Central deductions occur when Amazon automatically deducts funds from invoice payouts due to unreceived inventory (Shortages), ASN/pallet errors (Logistics penalties), or packaging/labeling non-compliance (Prep chargebacks).
Why do FC Shortage Claims happen in Vendor Central?▼
Shortage claims occur when Amazon FC receiving scanners log fewer units than listed on your invoice. Up to 70%+ of shortage claims are incorrect receiving errors and can be disputed successfully with Proof of Delivery (POD) documents.

Vendors can submit dispute claims in Vendor Central under Payments > Financial Disputes within the eligible 30-day to 9-month window, providing signed Bills of Lading (BOL), PODs, and carrier tracking logs.
What is a standard deduction percentage for Amazon 1P Vendors?▼
Average Amazon 1P deduction rates range from 3% to 8%+ of annual gross invoiced revenue. High-performing vendors maintain deduction rates below 2% by implementing automated dispute recovery workflows.
What are common preparation and packaging chargeback triggers?▼
Common prep chargebacks include missing scannable barcodes (FNSKU/UPC), loose master carton packaging, uncertified SIOC/FFP packaging, and improper pallet height or wrap compliance.
