How to Dispute Amazon Vendor Central Shortage Claims & Chargebacks

The Reality of Amazon 1P Shortage Deductions

For suppliers selling first-party (1P) goods to Amazon via Vendor Central, receiving shortages represent one of the fastest-growing revenue leaks. Because Amazon Fulfillment Centers rely heavily on automated optical scanners and robotic sorting, carton and each-level discrepancies are commonplace.

Key Amazon Chargeback Categories

1. Inbound Receiving Shortages: Amazon claims the delivered quantity was less than the invoiced quantity.
2. Purchase Order Non-Compliance: Late delivery, missing ASNs, or failure to schedule dock appointments via CARP.
3. Carton & Pallet Labeling Defects: Scanners failing to read GS1-128 shipping container codes.

Building an Irrefutable Proof Pack

Amazon’s automated dispute review algorithms reject generic invoices. To win an Amazon shortage dispute, you must assemble:

• Certified Scale Weight Tickets: Proving the truck weighed exactly what the complete order weighed at departure.
• Carrier Proof of Delivery with Amazon FC Stamp: Stamped by the dock attendant upon trailer drop.
• EDI 856 ASN XML Confirmation: Showing full functional acknowledgment (EDI 997).

Step-by-Step Dispute Process in Vendor Central

1. Navigate to Vendor Central › Financial Operations › Invoices & Shortages.
2. Locate the impacted invoice and select Dispute Shortage.
3. Attach certified weight receipts and stamped POD documents.
4. Provide a clear, concise dispute narrative referencing specific ASINs and quantities.

Dispute review typically takes 30 to 60 days. Approved credits appear on upcoming remittance schedules.
