Amazon FBA Reimbursement Guide: How to Recover Money Amazon Owes You

Why Amazon Owes FBA Sellers Money

Amazon's FBA fulfillment network processes hundreds of millions of shipments per year. Across that scale, errors are inevitable:

• Units get lost in Amazon's warehouse system
• Damaged inventory is disposed of without reimbursement
• Customers return items in unsellable condition that Amazon accepts
• Amazon incorrectly measures product dimensions and charges higher storage fees
• Inbound shipments are received short (fewer units than you shipped)

By Amazon's own policies, sellers are entitled to reimbursement for all of these errors. The problem: Amazon's systems do not automatically detect and pay all valid claims. Sellers who don't actively audit their accounts leave an estimated 1-3% of their FBA revenue on the table.

For a seller doing $500,000/year in FBA revenue, that's $5,000-$15,000 in unrecovered reimbursements annually.

Types of FBA Reimbursements

1. Lost Inventory

Amazon loses units in their fulfillment network. These can disappear during:

• Receiving inbound shipments
• Internal warehouse transfers
• Customer returns processing
• Disposal or destruction

2. Damaged Inventory

Amazon's warehouse staff damage units during picking, packing, or receiving. Amazon is liable for these damages.

3. Customer Returns — Unfulfillable

When customers return a product, Amazon grades it as:

• Sellable (returned to available inventory)
• Unfulfillable (damaged beyond resale — should trigger reimbursement if Amazon is at fault)
• Customer damage (usually not Amazon's liability)

4. Destroyed Without Permission

Amazon occasionally destroys inventory without your authorization. This triggers an automatic reimbursement, but the amount is often undervalued using Amazon's own calculation methodology.

5. Inbound Shipment Discrepancies

You ship 500 units; Amazon receives 480. The 20-unit discrepancy should be investigated.

6. Fee Overcharges

Amazon calculates FBA fees based on product dimensions and weight. If Amazon's measurements are incorrect (products get incorrectly measured), you may be paying higher storage fees, fulfillment fees, or referral fees than you should.

7. Order Errors

Amazon occasionally fulfills orders with wrong quantities, wrong products, or sends damaged items to customers. Amazon covers these.

How to File FBA Reimbursement Claims

Step 1: Gather Evidence

For each claim type:

• Lost inventory: Screenshot from Inventory Adjustments showing the lost quantity and date
• Inbound discrepancies: Your shipping carrier proof of delivery showing units shipped
• Damaged units: Inventory Adjustment report entry
• Fee overcharges: Product dimensions from your supplier or measured in-house

Step 2: Open a Seller Central Case

Go to Seller Central → Help → Contact Seller Support → Select the appropriate issue category.

• "FBA Issue — Missing Inventory"
• "FBA Issue — Customer Returns Reimbursement"
• "FBA Issue — Inbound Shipment Discrepancy"

Be specific: provide the ASIN, shipment ID, transaction ID, and date range. Vague tickets get generic responses.

Step 3: Follow Up

Amazon's first response is often automated and may deny the claim incorrectly. Escalate by:

1. Replying with additional evidence
2. Asking the case to be escalated to the FBA Investigation team
3. Submitting a second case with different framing if the first is wrongly denied

Success rates improve significantly with persistence and specific documentation.

Automation Options

Manual auditing takes time proportional to account size. For FBA sellers doing over $100K/year in revenue, automation tools pay for themselves quickly.

• Run your own reports and file claims manually using a spreadsheet template
• Time-consuming but no recurring fees

• GETIDA, Helium 10 Refund Genie, Refunds Manager
• Charge 20-25% of recovered funds as their fee
• No upfront cost — fee only on success
• Best for sellers who don't want to manage the process themselves

• Catalayer Claim Pilot — guides you through building the evidence package and drafting case submissions
• Reduces time per claim while keeping you in control of the filing

• Some agencies handle everything including communication with Amazon
• Higher fees but truly hands-off

How Much Should You Expect to Recover?

Industry benchmarks:

• New audit (first 18 months): 0.5-2% of FBA revenue in the audit period
• Ongoing monthly audit: 0.1-0.5% of monthly FBA revenue

These vary significantly by:

• Category (high-velocity, small items have more discrepancies)
• Warehouse distribution (more geographies = more transfers = more discrepancy opportunities)
• Account history (newer accounts tend to have more unclaimed refunds)

Preventing FBA Losses

Recovery is valuable, but prevention is better:

1. Label everything correctly — Unstickered or mislabeled inventory gets misrouted
2. Take photos before shipment — Proof of what you shipped in case of inbound disputes
3. Use Amazon prep services for fragile items — Amazon is liable for prep damage
4. Set up email notifications — Enable all FBA inventory notification types in your account
5. Reconcile every inbound shipment within 60 days — Amazon's investigation window shrinks over time
6. Check dimensions quarterly — Amazon remeasures products periodically; incorrect measurements can quietly inflate your fees
