Overview

Amazon occasionally reverses reimbursements that were previously issued to FBA sellers. This happens in two main scenarios: when replacement inventory is returned to your account instead of a cash payout, or when the original fulfillment defect that triggered the reimbursement gets resolved. Understanding how these reversals work is essential for maintaining accurate financial records and avoiding confusion when unexpected charges appear on your reports.

Key Points / What Sellers Need to Know

• Two types of reversals exist — Amazon reverses reimbursements either by returning replacement inventory to your account or by fixing the underlying defect that caused the original payout.
• Reversals appear on your Reimbursements report — Look for entries with a "Reversed Reimbursement" reason code to identify these transactions.
• Negative quantities signal a reversal — When you see negative values in the cash reimbursed column, that indicates money being clawed back from a prior payout.
• Historical data matters — You may need to expand your search period to the full 18 months to locate the original reimbursement transaction linked to a reversal.
• Replacement SKUs may look unfamiliar — Inventory returned through reversals sometimes carries a new merchant SKU prefix because original labeling was lost during fulfillment.

How Replacement Inventory Reversals Work

When Amazon locates or re-identifies inventory that was previously lost or mislabeled in the fulfillment network, they return the physical units to your account rather than keeping the cash reimbursement in place. In these cases, the reversed transaction on your Reimbursements report will show a negative number in the cash reimbursed column and a corresponding positive number in the inventory quantity column. The net effect is zero — you are giving back the cash but receiving the equivalent product units. These replacement units contain the same products as your original listings, but they may appear under a different merchant SKU because the original labeling that linked them to your existing listings was lost during the inbound process. This commonly occurs when items were mislabeled during shipping and could not be matched to your seller account at the time they were received.
