How FBA Reimbursements Work
When Amazon loses or damages your inventory in a fulfillment center, you are entitled to a reimbursement. Under the policy Amazon rolled out in 2025, losses that happen before a customer order are reimbursed at your product's sourcing cost: the price you paid to manufacture or acquire the unit, excluding shipping, duties, and your margin. Amazon estimates that cost for you, and sellers with documentation can contest low estimates.
Two things make this a finance problem, not just an ops chore. First, the claim windows are short: most fulfillment center claims must be filed within 60 days, so an annual cleanup misses money that is already unrecoverable. Second, even a successful claim only returns your cost. The margin you would have earned on those units is gone, and if your books carry the inventory at landed cost while the reimbursement pays bare sourcing cost, the difference quietly distorts your P&L.
The sellers who recover the most treat reimbursements as a monthly reconciliation: compare what you shipped in, what Amazon says it holds, what was destroyed or returned, and what was paid out, then file on every gap with invoices attached.
FBA Reimbursement FAQs
Since Amazon's 2025 policy update, inventory that is lost or damaged in a fulfillment center before a customer orders it is reimbursed based on your product's sourcing cost (what you paid to manufacture or acquire it), not its expected sale price. Amazon estimates that cost automatically, and you can submit documentation to correct the estimate if it is too low.
Claim windows tightened in late 2024. Most claims for inventory lost or damaged in fulfillment center operations must now be filed within 60 days of the event being reported. Customer-return claims have their own window tied to the refund date. Waiting until quarter-end to audit is often too late.
Sometimes. Amazon auto-reimburses many warehouse losses, but auto-reimbursements routinely use Amazon's own estimate of your sourcing cost, and plenty of eligible cases are never flagged at all: inbound shipment discrepancies, destroyed returns, and units damaged during removal orders are common misses. A monthly manual audit against your inventory ledger usually finds money.
Because sourcing cost excludes your margin. If a unit cost you $8 to make and sold for $30 with roughly $9 of Amazon fees, a lost unit reimbursed at $8 leaves about $13 of gross profit unrecovered. That gap is a real write-off and belongs in your books, which is exactly why lost inventory hurts more than the reimbursement report suggests.
Supplier invoices or manufacturing cost documentation, inbound shipment records (what you shipped versus what Amazon received), and your inventory ledger reports. If Amazon's sourcing-cost estimate is below your documented cost, submitting invoices gets the reimbursement corrected.
Lost Inventory Should NeverBe Lost Money
Futureproof books every Amazon reimbursement into your ledger as income and nets the clawbacks against it, so a recovery never hides inside sales and your margin per SKU stays honest.
