Why Did Amazon Reverse My FBA Credit?

A credit arrives for units Amazon lost. Weeks or months later it is taken back, with nothing new in your stock and no explanation attached to the debit. Why did Amazon reverse my FBA credit is a question the policy does answer, and the answer sets a condition that is easy to check and often is not met.

What the policy actually says

Amazon's FBA inventory reimbursement policy states it directly: "If a reimbursed item is later found and returned to your inventory, we reserve the right to reverse the reimbursement credit that was applied to your account."

Read the two halves separately. Found and returned to your inventory. A reversal with no corresponding inventory event does not match the clause it is being justified by.

Amazon staff have described the same two grounds in the Seller Forums: a reimbursement can be reversed if it was made in error, or if the item was later found and returned. In that thread, the recommendation is to dispute through Seller Support within 60 days if you believe the reversal was wrong.

Since March 10, 2025, reimbursement value is based on sourcing cost rather than sale price, with a cap of 5,000 dollars per unit. If you have not submitted your own figures, Amazon uses its own estimate, which is why setting your sourcing cost yourself changes what both the credit and the reversal are worth.

Prove it in the Inventory Ledger

This is the whole procedure, and it takes about fifteen minutes per case.

1. Open the Reimbursements report in Seller Central and filter to the reversal. Record the date, the MSKU, the quantity and the amount taken back. A reversal appears as a negative amount tied to the original reimbursement ID.
2. Pull the Inventory Ledger, detailed view, for that MSKU. Set the date range from before the original loss event through today. Do not use a short range; the matching event can post months later.
3. Look for the Found event. You are looking for a positive adjustment with the same quantity as the reversal, dated on or before the reversal. If the ledger shows the units coming back, the reversal is correct and the case ends there.
4. If there is no matching Found event, you have your evidence. Export both reports. The pair of them is the argument: money out, no units in.
5. File the case within 60 days of the reimbursement. Name the reimbursement ID, the reversal date and the ledger range you checked, and state that no corresponding inventory adjustment exists. A general complaint about reversals gets a policy link back; a ledger range with nothing in it gets a human.

Is your FBA credit unfairly reversed?

What sellers report, and what is not confirmed

Two patterns come up repeatedly in the forums. Neither is confirmed by Amazon, and both should be treated as what other sellers observe rather than as established behaviour.

• Reversals larger than the original credit. In one thread, a seller documents a unit reimbursed at a sourcing cost of 10.34 dollars and reversed at 14.78, and Amazon's reply confirms only that the case was under investigation by another team.
• Units removed from old shipments instead of added back. Another seller asks others to check their reversed reimbursements after finding that the ledger deducted units from a shipment 17 months old rather than recording a find.

If either matches what your ledger shows, say so in the case with the exact rows. Do not present it as a known Amazon practice, because it is not documented as one.

Keep the clock from running out

The 60-day window is the part that quietly costs money. Reversals are not announced, they do not generate a notification, and they land in a report nobody opens in Q4. By the time a quarterly reconciliation catches one, the window is usually closed.

• Reconcile reimbursements monthly and look specifically at negative lines.
• Keep the Inventory Ledger range wide. A find posted five months after the loss is normal.
• Treat it like any other claim window with a hard edge, the same way the SAFE-T filing window or a shipment closing with units missing does.

SellerKey surfaces reimbursements and reversals against the inventory movements for the same SKU, so a debit without a matching find is visible without exporting anything. It reports what your account shows; it does not file claims for you.
