Amazon FBA reimbursement: the complete claims guide.

Every quarter Amazon loses, damages, or mis-charges on inventory inside its fulfillment network, and most sellers leave 1-3% of revenue sitting in unclaimed reimbursements. Here's the exact playbook we use to audit, document, and recover what you're owed.

The problem

Most sellers are leaving real money inside Amazon's warehouses.

FBA reimbursements are the closest thing to free margin on Amazon, money you've already earned, sitting in a queue waiting to be claimed. But the system is designed to be missed. Auto-reimbursements undercount. Claim windows expire. Reports don't reconcile cleanly. And Seller Support will reject any claim that isn't bulletproof on the first attempt.

  • Inbound shipments where Amazon receives fewer units than you shipped, and you never reconcile the discrepancy
  • Warehouse-lost units that auto-reimburse at the wrong cost basis, often below your actual landed cost
  • Customer returns that never make it back to inventory, no reimbursement, no restock
  • Damaged units written off by Amazon without notification, no claim ever filed
  • Removal orders where units go missing in transit, with no follow-up after the 30-day window
  • FBA fee overcharges from incorrect dimensional or weight measurements that no one audits
Our approach

Audit monthly. Document obsessively. File on time.

Reimbursement recovery isn't complicated, it's a discipline. The brands that recover the most run the same audit every 30 days, attach the same evidence on every claim, and never let a Shipment ID age past its claim window. Here's the process.

01

Monthly reconciliation audit

Pull Inventory Adjustments, Received Inventory, Reimbursements, and FBA Customer Returns reports. Reconcile against shipment manifests and removal orders to surface every discrepancy older than 30 days.

02

Evidence-first claim filing

Every case opened with Seller Support references a specific Shipment ID, FNSKU, order ID, or removal order ID, plus the exact unit count and the exact dollar amount owed. Vague claims get rejected.

03

Reopen and escalate

Roughly 30-40% of first-pass claims get denied with boilerplate. The recovery comes from reopening with additional evidence, escalating to a senior Seller Support rep, and citing the specific policy section. Persistence is the strategy.

What you get

The 6 reimbursement categories worth auditing.

  • Lost inbound shipments, units shipped but never marked received at the fulfillment center
  • Warehouse-lost inventory, units that disappeared after being received and stowed
  • Warehouse-damaged inventory, units damaged inside Amazon's network, not by the customer
  • Customer return discrepancies, units refunded to the customer but never returned to your inventory
  • Destroyed or disposed inventory, units removed from your account without a corresponding reimbursement
  • FBA fee overcharges, incorrect dimensional or weight measurements inflating your per-unit fees
How we work

How to file an FBA reimbursement claim, step by step.

Step 1

Pull the reports

Seller Central → Reports → Fulfillment. Export the last 18 months of Inventory Adjustments, Received Inventory, Reimbursements, FBA Customer Returns, and Removal Order Detail reports.

  • Filter Inventory Adjustments for reason codes A through Q (Amazon-fault adjustments)
  • Cross-reference against the Reimbursements report to find adjustments without a matching credit
  • Flag every Shipment ID with a received-quantity variance > 0
  • Pull customer return data for orders 60-105 days old, the closing window for return reimbursement claims
Step 2

Build the evidence packet

For each discrepancy, assemble the exact data Seller Support requires. Missing fields are the #1 reason claims are denied on first review.

  • Shipment ID and creation date
  • FNSKU or ASIN and SKU
  • Units shipped vs. units received (or refunded vs. returned)
  • Date range of the discrepancy
  • Calculated reimbursement amount based on your average per-unit landed cost or sale price (whichever the claim type uses)
Step 3

Open the case

Seller Central → Help → Get Support → Selling on Amazon → Fulfillment by Amazon → Inventory issues. Pick the matching subcategory (lost inbound, lost inventory, damaged, destroyed, customer return, fee overcharge).

  • One claim per Shipment ID or per FNSKU, never bundle unrelated SKUs into a single case
  • Reference the specific report and date range in the case description
  • Attach the inventory adjustment screenshot or report excerpt
  • Request a reimbursement amount, don't leave it open-ended
Step 4

Track and reopen

Amazon typically responds in 3-7 days. Roughly a third of first-pass claims get denied with boilerplate, that's not the end, it's the beginning.

  • Log every case ID in a tracker with status and dollar amount
  • Reopen denied cases with additional evidence within 7 days
  • Escalate persistent denials to a Brand Specialist or Account Health rep
  • Cite Amazon's own policy language (FBA Lost and Damaged Inventory Reimbursement Policy) when pushing back
Ongoing

Run the audit every 30 days

The single biggest driver of recovery isn't the claim quality, it's never missing a claim window. Build the audit into a monthly close.

  • Last business day of each month: pull all reports and reconcile
  • Flag any Shipment ID older than 15 months for priority filing (the 18-month window closes fast)
  • Track recovery rate by claim type to identify which categories are leaking the most
  • Quarterly review of FBA fee charges against current Amazon rate cards
FAQ

Questions buyers actually ask.

What is an Amazon FBA reimbursement?+

When Amazon loses, damages, destroys, or disposes of your inventory inside its fulfillment network, or makes a fee or customer-return error in your favor, you're owed money back. Reimbursements are the formal claims process for recovering that money through Seller Central.

How far back can I file FBA reimbursement claims?+

Most claim types have an 18-month window from the date of the discrepancy. Lost-inventory and warehouse-damaged claims fall under this window. Customer-return reimbursement claims typically need to be filed within 60 days after the 45-day return window closes, so roughly 105 days from the original ship date.

Does Amazon auto-reimburse for lost or damaged inventory?+

Sometimes. Amazon auto-reimburses certain warehouse-lost and warehouse-damaged units, but the credits are easy to miss and frequently undercount the actual loss. You still need to audit FBA inventory reports against shipment, removal, and reimbursement reports to catch the gap.

What reports do I need to file a reimbursement claim?+

At minimum: the Inventory Adjustments report, Received Inventory report, Reimbursements report, FBA Customer Returns report, and the shipment summary (Shipment ID, FNSKU, units shipped, units received). Amazon will reject claims that don't reference specific Shipment IDs, FNSKUs, or order IDs.

What's the difference between lost, damaged, destroyed, and disposed?+

Lost: Amazon can't locate the units inside a fulfillment center. Damaged: units were damaged by Amazon (warehouse or carrier), not the customer. Destroyed: Amazon destroyed the units, usually after a removal order or quality flag. Disposed: Amazon disposed of units at your request or under their unfulfillable inventory policy. Each has its own claim flow.

Can I use a third-party reimbursement service?+

Yes, and many sellers do, they typically take 15-25% of recovered funds. The trade-off: speed and coverage vs. margin. Mid-size brands doing $1M-$10M on Amazon usually recover more by combining a monthly internal audit with a paid service for the long-tail edge cases.
