Reimbursements and fee forensics: the money Amazon owes you
- You know the claim types Amazon reimburses — and the evidence that carries them.
- You know why a maintained cost value in your account decides the size of your reimbursement.
- You audit dimensions and weight as a source of error in its own right, not as a detail.
- You have a monthly audit run that finds claims before deadlines kill them.
FBA is a warehouse with millions of movements a day. In any system that size, things get lost, damaged, miscounted or mismeasured. Amazon reimburses such cases — but only part of them automatically, and only while deadlines run. This lesson turns chance finds into a process. It is the logical continuation of lesson 6: that one was about what you pay, this one about what you overpaid.
Reimbursements are a legitimate claim, not a bag of tricks. Inventing claims, filing the same case repeatedly or firing off automated bulk requests risks your account — Amazon treats that as abuse. A clean process is entirely sufficient: in a well-run account the genuine cases are numerous enough.
1The claim types
| Case | What happened | Where you see it |
|---|---|---|
| Lost in the warehouse | Units vanished from inventory without being sold | Inventory ledger: receipts minus outbound do not reconcile |
| Damaged in the warehouse | Amazon rendered stock unusable or booked it as damaged | Inventory adjustments with a matching reason |
| Receiving discrepancy | Fewer units booked than delivered | Shipment reconciliation: shipped versus received |
| Refunded but never returned | The customer got their money; the goods never reached the warehouse | Returns report against the inventory ledger |
| Returned but booked unsellable | Stock came back and was graded defective without customer damage | Returns report, condition column |
| Wrong dimensions or weight | The stored size tier does not match reality | Fee preview against your own measurement |
| Removal order lost | Removal requested, goods never arrived | Removal order report against your own goods-in |
Imagine handing your stock to an enormous warehouse someone else runs. At month end you get a receipt. Almost nobody checks it — and that is exactly where the errors sit. This is not about suspecting the warehouse: with millions of movements, errors are normal. What is unusual is how few customers do the arithmetic.
2The valuation rule: manufacturing cost, not selling price
For losses occurring before a customer order, Amazon has since a policy change in spring 2025 reimbursed the manufacturing cost value — your bare purchase or production price, without freight, duty, handling or margin (evidence level: practice; the policy sits in Seller Central behind the login). Previously the selling price was the usual basis.
From that follows the single most important action in this lesson: maintain your cost values in the account. Without stored costs Amazon estimates — and estimates rarely fall in your favour. Concretely:
- Enter a cost value per SKU and update it with every new purchase price.
- Only include costs that match the definition. Folding in freight and duty invites queries that stall the whole claim.
- Keep evidence to hand: the supplier invoice per batch. Without it, every figure is an assertion.
Fourteen units of the AURELO set vanish in the warehouse. With no cost value stored, Amazon reimburses on its own estimate — €3.10 per unit in this example. With a stored cost value of €4.50 (the actual supplier invoice, excluding freight) it is €63 instead of €43.40. The €20 difference sounds small; extrapolated across a year with a shade under one percent shrinkage over the whole range it becomes a three- to four-figure amount — for an entry made once per SKU.
3Dimensions and weight: the silent permanent overpayment
The fulfilment fee follows Amazon's own measurement of the ready-to-ship unit (lesson 6). If that measurement differs from reality you pay the difference on every single sale — permanently and without warning. That makes this the most rewarding case of all: one corrected value applies to every future order.
- Measure yourself, properly. Packed and sealed: length, width, height, weight. Several units from different batches, and note the worst value.
- Compare with the stored values. The fee preview shows which size tier Amazon is using.
- Request a re-measurement on any discrepancy. With photos: product against a tape measure, scale with the reading visible, both in the same frame as the label.
- Always check after packaging changes. New packaging does not automatically mean a new measurement — otherwise the old tier stays.
4Deadlines: the point where claims die
Deadlines differ by claim type, and the publicly circulating figures contradict each other: 60 days from the loss or damage notice for warehouse cases, markedly longer periods for other claim types and 90 days for removal orders are all cited (evidence level: disputed — what counts is the figure in your account). For practice that means two things, both independent of the exact number:
- A monthly audit run beats any deadline debate. Check every month and you are never in the position of having to invoke a deadline.
- Plan against the shortest circulating deadline. The same logic as the conservative corridor in Listing L16: work to the strictest figure and you lose nothing if a more generous one applies.
“Tidying up” once a year and discovering half the cases have expired. Reimbursements are not an annual project but a 30-minute monthly routine. The second most common mistake is the opposite: filing the same matter repeatedly because the first answer was unsatisfying. Duplicate claims count as abuse — you follow up WITHIN the existing case, with new evidence.
5The monthly audit run in 30 minutes
- Pull the inventory ledger (previous month) and reconcile per SKU: opening stock plus receipts minus sales minus returns received = closing stock. Every discrepancy is a candidate.
- Put the reimbursements report beside it. Amazon reimburses many warehouse cases automatically today (evidence level: practice) — anything already listed there is settled and is not filed again.
- Check returns against inventory receipts: which refunded order has no return into the warehouse?
- Reconcile open shipments: shipped versus received, per shipment.
- Spot-check the fee preview against your own measurements — two or three SKUs a month give rolling coverage.
- Open cases: one per matter, with a report extract, period, SKU, unit count and amount. Bundled claims across several matters get a blanket answer.
March's audit run shows a gap of 9 units on the AURELO set. The reimbursements report already contains 5 of them automatically — 4 remain. For those 4 the inventory ledger supplies date, reason and quantity. The case is opened with exactly those four lines, not with the sentence “units are missing”. Processing time: eleven minutes. Result: €18 — unexciting on its own, but it is one of an average five cases a month, and the routine behind it costs nothing extra.
6Service providers: when a percentage model pays
Providers exist who run the reconciliation automatically and keep a share of the reimbursement. The sober assessment:
- In favour: completeness on large ranges. With 300 SKUs you will never find everything by hand.
- Against: access to your account and responsibility for the claims. In an abuse case your account is liable, not the provider.
- The line sits, practically, where your own audit run takes more than an hour a month. Below that, doing it yourself is cheaper and more instructive — you see problems no reimbursement report shows.
- Cost value per SKU stored in the account and updated with every purchase.
- Supplier invoices per batch filed within reach.
- Monthly audit run as a fixed calendar task.
- Automatically reimbursed cases reconciled before every claim.
- One case per matter, with a report extract rather than a description.
- Dimensions and weight checked on a rolling basis, immediately after any packaging change.
- No duplicate claims, no automated bulk filing.
7Expert insight: the chain of evidence that makes a case undeniable
The difference between “rejected” and “reimbursed” almost never lies in the facts but in the form. A claim an agent can follow in two minutes gets processed; one that raises questions gets closed. A solid chain of evidence has four links:
| Link | What it proves | Where it comes from |
|---|---|---|
| 1. The goods existed | They were delivered and booked | Shipment closure with received quantity |
| 2. They were not sold | No outbound through an order | Sales report for the period |
| 3. They are gone anyway | Inventory adjustment with reason and date | Inventory ledger |
| 4. They were not already reimbursed | No entry in the reimbursements report | Reimbursements report for the same period |
Evidence all four links with lines from Amazon's own reports and you are not making a claim, you are presenting an invoice. Link 4 is the one most people omit — and it is the most common rejection reason: “already reimbursed”. A claim that proves for itself that it is not a duplicate takes the easiest rejection out of the agent's hands.
Three subtleties separate a good process from a very good one:
- Pick generous periods and precise numbers. A loss is sometimes booked weeks after the event. Pull reports across two months but name exact lines in the claim — the wide window finds the case, the tight figures make it checkable.
- Keep your own numbering. Every case gets an identifier in your own sheet, with date, amount, case number and outcome. Without that sheet you will eventually file a duplicate — and that is the one way a legitimate routine turns into an account risk.
- Analyse rejections rather than filing them away. When the same reason comes back three times, your claim is missing a link. That is process information, not a run of bad luck.
And one thought beyond reimbursement: forensics is also an early warning system. If damage clusters on one SKU, the warehouse is rarely at fault — the packaging is. If receiving discrepancies cluster with one supplier, Amazon is rarely at fault — the count at packing is. Recover only the money and miss the pattern, and you recover the same money every month instead of fixing the cause once.
Tools that file claims automatically produce exactly the bulk patterns Amazon reads as abuse — especially when they refile cases that were already reimbursed automatically. Automating DETECTION is entirely safe: a script that reconciles inventory and hands you a list is pure legwork. Filing stays a human with a spreadsheet.

Frequently asked
How much does a clean audit run typically recover?
That depends entirely on range size and stock movement — a general percentage would be invented. What is reliable is the structure: the amounts per case are small, the annual total is not, and the real gain is often not the money but the pattern the audit makes visible.
What do I do when a case is rejected?
Follow up in the EXISTING case, never open a new one. And take the reason seriously: if a link in the chain of evidence is missing, supply exactly that — with lines from Amazon's own reports. If the same reason comes back three times, it is your claim format, not bad luck.
Do I have to audit dimensions for every product individually?
Not all at once. Two or three SKUs a month give full coverage across a year and keep the effort small. Immediate checks are needed on only two triggers: after a packaging change, and when the fee per unit rises with no visible reason.
