What Amazon owes youand won't pay unasked.

Inventory in Amazon's fulfilment centres can be lost or damaged in receiving, storage or transfers. Customers can be refunded for a return that never comes back, or comes back to a different condition. Most are reimbursed automatically. The remainder only gets paid when you open a case.

From Seller Central, download for the same period:

• Inventory Ledger (detailed view): every adjustment per FNSKU, including lost, damaged and found units.
• Reimbursements: what Amazon already paid, per FNSKU and reason, with the amount per unit.
• FBA Customer Returns: which refunded orders actually came back, and in what condition.
• Transactions (date range report): refunds per order.

Per FNSKU: units lost or damaged, minus units later found, minus units already reimbursed. What remains is still owed. Value it with Amazon's own reimbursement amount per unit from the same report.

Per order: refunds older than the return window with no matching customer return are candidates for a refund-related reimbursement.

Open cases in Seller Central with the FNSKU, the dates and the ledger lines. Amazon has changed its claim windows over time, so check the current rules on Seller Central and start with the oldest items.

Silentleak runs this check and the others like it on redacted exports, recovers what is owed in your name after you approve each claim, and charges only on money that reaches your account. Start a free scan of your own exports, or an estimate from four numbers.
