What Is Amazon FBA Inventory Credit? How It Works

An Amazon FBA inventory credit is the line Amazon posts to your account when it settles a claim over FBA stock it lost, damaged, destroyed or never returned to you. It is a credit, not a sale. And it does not always arrive as money: Amazon can settle the same claim with cash, with replacement units inside FBA, or with a mix of the two. That is why the amount in your financials almost never matches the number of units you lost.

This is the whole mechanism, column by column, with the reports that prove each figure.

What an FBA inventory credit is, in Amazon's own data

Every settled claim lands in one place first: the FBA Reimbursements report. In the Selling Partner API it is the report type GET_FBA_REIMBURSEMENTS_DATA, and Amazon's developer documentation describes it as itemized details of a seller's inventory reimbursements, including the reason for the reimbursement, with content updated daily.

The report has 18 columns. Three of them decide what you were actually paid:

• quantity-reimbursed-cash: units Amazon settled in money.
• quantity-reimbursed-inventory: units Amazon replaced in kind, as sellable FBA stock.
• quantity-reimbursed-total: the sum of the two.

That third column is the one most sellers read, and it is the one that tells you least. A claim for 12 units can close with 12 in quantity-reimbursed-total and 5 in quantity-reimbursed-cash. Seven units came back as inventory. No money moved for them.

Two more columns matter: amount-per-unit and amount-total, which carry the cash side, and original-reimbursement-id with original-reimbursement-type, which exist because a credit can be undone. If Amazon finds the units later, the credit is reversed and linked back to the original record.

Where the FBA inventory credit appears in your accounts

The credit shows up three times, in three different shapes, and the names do not match. That is the single biggest source of confusion around this term.

1. In the FBA Reimbursements report, itemized per SKU with its reason and case-id.
2. In the settlement report. The Flat File V2 Settlement Report condenses every charge into amount-type, amount-description and amount, alongside transaction-type and adjustment-id. A reimbursement is an adjustment, not an order, so it carries an adjustment-id and no order line.
3. In the summary and date range views, where it is grouped with other non sales credits. Sellers on the Amazon Seller Forums reconciling the monthly transaction file report that these credits land in the generic other column rather than in product sales, which is why the figure never ties to a sales report.

If your bookkeeping treats that credit as revenue, your sales number is wrong and your reimbursement number is wrong at the same time.

How Amazon values a unit it lost

This is the part to confirm against your own policy page before you build a number on it. Amazon's announcements posted on the Seller Central forums state that reimbursements for warehouse losses are calculated on the sourcing cost of the item, which is what you paid to buy or make it, and that shipping, handling and customs duties are excluded. The same announcements say you can view and override that figure on the Manage Your Sourcing Cost page in the Inventory Defect and Reimbursement portal.

The windows quoted in those announcements are specific: a fulfillment center claim for an item lost or damaged in the warehouse must be filed no later than 60 days after the item was reported lost or damaged; an FBA customer returns claim goes in between 60 and 120 days after the refund or replacement date; a removal claim for items lost in transit runs from 15 to 75 days after the shipment creation date, and all other removal claims within 60 days of delivery back to you.

Treat those day counts as what Amazon announced to sellers, not as a figure read from a policy page. The policy hub does not open without a Seller Central session, so verify them inside your account before you plan a claim around them.

Paid in units or paid in cash?

A worked example, end to end

Say a fulfillment center reports 12 units of one SKU as lost. Your approved sourcing cost on that SKU is 9.40 US dollars. Your selling price is 29.99 US dollars.

Amazon settles the claim like this:

• 5 units in cash. amount-per-unit 9.40, amount-total 47.00.
• 7 units in inventory. Seven replacement units become sellable again in FBA.
• quantity-reimbursed-total: 12.

What that means in practice:

• Your financials gain 47.00 dollars of credit, not 359.88 dollars of lost retail value, and not 112.80 dollars either. Only the cash units are paid.
• The 7 inventory units are not profit. They are stock you now have to sell again, and they start paying storage again from the day they land.
• If Amazon later finds the 5 cash units, expect a reversal row carrying original-reimbursement-id.

The useful number is therefore not amount-total on its own. It is amount-total divided by quantity-reimbursed-total, compared against your sourcing cost. Anything well below your sourcing cost means part of the claim closed in units, not money.

How to reconcile it without guessing

The reimbursement report tells you what Amazon paid. It does not tell you what left the warehouse. For that, Amazon publishes the Inventory Ledger Report, detailed view, report type GET_LEDGER_DETAIL_VIEW_DATA, which holds 18 months of movements and accepts an eventType filter with the value Adjustments. The summary view carries the columns that close the loop: Found, Lost, Damaged, Disposed, Warehouse Transfer In/Out and Unknown Events.

The reconciliation is one subtraction. Units adjusted out in the ledger, minus units in quantity-reimbursed-total, equals units Amazon has not settled yet. That gap, not the credit, is where the money is.

One operational detail: a generated SP-API report is retained for 90 days by default, per Amazon's report type reference. After that you request it again. If you are reconciling a quarter, download it while it exists.

What it means for your margin

An FBA inventory credit is a partial refund of cost, never a recovery of margin. On the example above, a 12 unit loss at a 29.99 dollar price point removes the gross margin on all 12 and returns the cost of 5. The loss is real even when the claim closes as approved.

So the decision this changes is a reporting decision, not a claims decision: stop reading the credit as money recovered, and start reading the two quantity columns separately. One is cash. The other is inventory you have to sell twice.

For the wider mechanics of claims, deadlines and which report proves what, see our guide to Amazon FBA reimbursements. If a credit you already banked disappeared from your account, the reversal path is covered in why Amazon reverses an FBA credit. And for keeping the ledger clean before any of this happens, see Amazon FBA inventory management.
