What is an inbound shortage claim, and why was one example won?

An inbound shortage claim involves a discrepancy between the quantity of inventory you shipped to Amazon and what they received. In the won example, the seller had detailed packing slips, carrier proof of delivery, and a clear audit trail showing the shipment was intact upon delivery. This evidence convinced Amazon to reimburse the missing units.

Can you explain a lost FBA claim due to return fraud?

In a lost return fraud case, a customer claimed to return an item but sent back a different, lower-value product or an empty box. The seller lost the claim because they lacked photographic evidence of the original item's condition before shipment and failed to provide serial numbers or unique identifiers. Amazon sided with the customer due to insufficient seller documentation.

How does invoice verification impact FBA reimbursement claims?

Invoice verification is critical for proving the cost and authenticity of your inventory. In a won example, the seller provided valid invoices from a verified supplier that matched the ASINs and quantities in dispute. This allowed Amazon to confirm the items were legitimate and eligible for reimbursement. In a lost example, the seller submitted invoices with mismatched dates or supplier details, leading to denial.

What common mistakes cause sellers to lose FBA reimbursement disputes?

Common mistakes include failing to keep detailed shipping records, not photographing inventory before sending to Amazon, using generic or unverifiable invoices, and missing the 18-month claim window. Sellers also lose when they cannot prove the item was in sellable condition or when they rely on Amazon's internal data without independent evidence.

How can sellers improve their chances of winning FBA claims based on these examples?

Sellers should maintain meticulous records: save packing lists, carrier receipts, and photos of inventory. Use unique identifiers like serial numbers or FNSKU labels. Always obtain valid, itemized invoices from suppliers. File claims promptly within Amazon's deadlines, and cross-reference your own data with Amazon's reports to catch discrepancies early.

3 Real FBA Claim Examples: Why They Were Won (Or Lost) in Sell...

Learn from real cases. Check out these 3 fba claim examples detailing won and lost disputes, and learn how to structure your evidence to secure reimbursements.

Introduction: Learning from Real FBA Disputes

Filing reimbursement claims inside Seller Central is often a trial-and-error process for sellers. FBA policies are complex, and subtle formatting errors or missing fields on invoices can result in immediate denials. One of the best ways to improve your claim success rate is to study real cases that other sellers have resolved.

This guide analyzes three real FBA claim examples: an inbound pallet shortage, an Alibaba invoice denial, and a customer return serial swap. We cover the evidence submitted, why the claims were approved or rejected, and the lessons you can apply to your own store.

When preparing dispute documentation, sellers can utilize our free browser tools: extract high-resolution proof screenshots using the PDF to Image Converter, audit lost revenue with the Amazon FBA Fee Calculator, and verify package scan barcodes using the Amazon Barcode Scanner.

1. Case Study 1: The Inbound Pallet Shortage (Result: WON)

Scenario: A seller shipped 3 pallets of inventory using an Amazon Partnered Carrier. Upon arrival, the fulfillment center logged a shortage of 150 units for a popular product.

Initial Filing: The seller submitted a case with a basic manufacturer packing slip. Support denied the claim, stating the items were missing from physical scans.
The Appeal Evidence: The seller retrieved the signed Bill of Lading (BOL) from their carrier portal. The BOL showed the Amazon receiving stamp and carrier driver's signature with a pallet count of 3.
The Resolution: The seller reopened the case and uploaded the signed BOL alongside the supplier invoice. Amazon verified the receiving stamp and approved a reimbursement of $4,500.

2. Case Study 2: The Denied Alibaba Invoice (Result: LOST, then WON on appeal)

Scenario: A seller filed a claim for 50 lost units inside the warehouse. They submitted an Alibaba Transaction Screenshot as proof of sourcing.

The Rejection: Amazon support rejected the document, stating they could not verify the transaction and that the screenshot lacked supplier business tax registrations.
The Corrective Action: The seller contacted their supplier and requested a formal commercial tax invoice containing the supplier's registration number, LLC address, and the buyer's storefront details.
The Appeal Resolution: The seller resubmitted the formal invoice and highlighted the matching payment details. Amazon verified the document and issued the reimbursement.

3. Case Study 3: The Customer Return Serial Swap (Result: WON)

Scenario: A customer returned a high-value smartwatch and received a full refund. The seller created a removal order to inspect the returned item and found it was an older model.

The Evidence: The seller photographed the smartwatch serial number next to the carrier shipping label and the white LPN return label. The photo showed that the returned serial number did not match the original listing details.
The Support Case: The seller opened a customer return discrepancy case, uploaded the photos, and provided the removal order tracking information.
The Payout: Amazon verified the serial mismatch and reimbursed the seller for the retail value of the smartwatch.

Q: What if the partnered carrier lost an entire pallet? Open a case immediately with Seller Central, select 'Transit Loss', and provide the signed BOL showing the driver accepted the pallet.
Q: How long does a shipping claim review take? Standard reviews take 5 to 10 business days depending on case complexity.
