2. Read the results
Claim these
Per FNSKU: units lost (reason M) minus units found again (reason F) minus units reimbursed, plus units damaged in Amazon's warehouse or by its carrier and not reimbursed.
Lost & damaged detail
The full calculation per FNSKU, including recent losses that are still within the grace period.
Events
The ledger lines behind each number: date, reference ID and fulfilment centre. This is your evidence.
Reimbursements received
What Amazon has already paid, by reason.
3. What to do next
- In Seller Central open Help → Get support → Selling on Amazon → Fulfilment by Amazon → Investigate lost / damaged inventory.
- Give the FNSKU, the units, and the reference IDs and dates from the Events tab. One case per FNSKU works best.
- Track the case. If it's closed without payment, reply with the ledger lines and ask for re-review.
4. Good to know
- •Use a long ledger range: lost units are often "found" weeks later, which cancels the claim.
- •Amazon has a time limit for claims on older losses. File as soon as the grace period passes.
- •The value per unit comes from your past reimbursements for that FNSKU when available; otherwise type it in.
5. FAQ
Why do I see damaged units when Amazon already disposed of them?
Units moved into "warehouse damaged" or "carrier damaged" are counted once, when Amazon damaged them. If they were reimbursed under a "Damaged" reason, they drop out of the claim list.
Does it cover customer returns that never came back?
Not yet. Those need the FBA customer returns report plus refunds; it's on our list.
It says a column is missing. What now?
You probably uploaded a different report, or Amazon renamed a column. Download the report exactly as in step 1. If it still fails, tell us the report name and we'll add support.
