Amazon loses & damages inventory constantly and owes you money. Estimate it, beat the 180-day clock, and file it.
Estimate only. Amazon pays by your sales history + the ASIN's price/sales history, so the real payout can be more or less. Anything past 180 days is gone — run this at least every 6 months.
How to file it (do this monthly)
Shipment problems: Inventory → Manage FBA Shipments → "problems with your shipment" → Resolve → Submit Investigation.
Lost/damaged audit: Reports → Fulfillment → Inventory → Inventory Adjustments → last 180 days → Generate report.
Check what they already paid: Reports → Fulfillment → Payments → Show More → Reimbursements.
File a case: Help → Contact Us → Fulfillment by Amazon → Other FBA issue → attach ≤5 files per case (more looks bot-like and gets denied).
Be polite — rude = "deny, deny". Use the message below.
Paste-ready case message
Subject: Reimbursement request — damaged/lost inventory
Hello, please review the attached files for ASINs where inventory was lost or damaged by Amazon and not yet reimbursed. If your records show the same, please reimburse our account. Thank you for your time and attention to this matter.
