Amazon Owes You Money — You Just Have to Find It
Amazon processes millions of FBA shipments a year. At that scale, inventory errors are simply inevitable: units get lost in transit between fulfillment centers, damaged during handling, restocked incorrectly after a customer return, or charged the wrong fee due to a mismeasured box. Amazon’s own reimbursement policy exists to cover exactly these situations — but the burden of finding the discrepancy is entirely on the seller. Amazon doesn’t proactively surface most of what it owes you; it waits to see if you notice.
Most sellers don’t reconcile their FBA reports closely enough, on a tight enough schedule, to catch everything before the claim window closes — which is exactly why this category of recoverable revenue goes unclaimed so consistently.
The Four Reimbursement Categories
| Category | What It Covers |
| Lost inventory | Units that entered Amazon’s fulfillment network but never made it to a customer or back to you — including inter-warehouse transfer losses |
| Damaged inventory | Units damaged at a fulfillment center, in transit between FCs, or during customer handling and never made sellable again |
| Customer return discrepancies | A customer returns an item, but it’s never correctly restocked into your available inventory — or an item is refunded without ever being returned at all |
| Fee overcharges | Amazon miscalculates a fee based on incorrect product dimensions or weight, overcharging your storage or fulfillment fee |
A rarer but real fifth category: duplicate refunds, where Amazon refunds a customer twice for the same order, or issues a chargeback after already processing a refund. These are claimable if caught within the filing window.
What Changed in 2026 (and Why It Matters for Your Claim)
The Claim Window Got Much Shorter
Effective October 23, 2024, Amazon automated much of the reimbursement process — and cut the manual claim window from roughly 18 months down to 60 days for most lost/damaged inventory cases. Removal-order claims remain on a separate, longer window (around 90 days) in most current guidance. Given how frequently Amazon has adjusted these windows in the past two years, always verify the current deadline in Seller Central before assuming a specific number — but the clear trend has been toward shorter windows and more automation, which raises the cost of an infrequent, manual review process.
Reimbursements Are Now Based on Manufacturing Cost, Not Selling Price
This is the change that catches most sellers off guard. As of a policy shift around March 31, 2025, Amazon calculates many lost/damaged reimbursements based on your manufacturing cost, not your retail selling price. If you sell an item for $29.99 but Amazon estimates your manufacturing cost at $6, the reimbursement is closer to $6 — not the $29.99 you would have earned from the sale. This can cut payouts dramatically, especially on high-margin products.
The defense: keep accurate, submittable cost documentation for every SKU. When Amazon requests cost data — or when we file a claim on your behalf — having your actual manufacturing cost on record (rather than letting Amazon default to its own, often lower, estimate) is what protects the size of your reimbursement.
More Is Automated — But Automation Doesn’t Catch Everything
Amazon’s auto-reimbursement engine now resolves a meaningful share of lost/damaged cases without the seller lifting a finger. That’s genuinely good news — but automation is pattern-based, and it reliably misses fee overcharges, return-discrepancy cases, and edge cases that don’t match its standard triggers. A monthly manual audit alongside automation is still where most of the additional recovery comes from.
How We Find What Amazon Owes You
Step 1: Inventory Reconciliation Audit
We pull your FBA Inventory Adjustments Report and look specifically for negative adjustment codes without a matching reimbursement — E1 (damaged), E3 (damaged at fulfillment center), E7 (removed by customer), and M (missing/lost).
Step 2: Returns Reconciliation
We cross-reference your FBA Returns Report against what actually shows up back in your available inventory. A return Amazon processed but never restocked correctly is a common, easy-to-miss claim.
Step 3: Fee Audit
We check Fee Preview and Transaction View data against your products’ actual dimensions and weights to catch overcharges from mismeasured or misclassified items.
Step 4: Claim Filing With Full Documentation
Vague claims get denied. We file with specific order numbers, transaction IDs, timestamps, and — where the case requires it — supporting documentation like proof of delivery or signed bills of lading, written the way Amazon’s reimbursement reviewers actually expect to see it.
Step 5: Follow-Up and Escalation
Where a claim is denied without adequate explanation, we escalate rather than letting it drop — many legitimate claims are initially rejected on a technicality and succeed on a properly documented follow-up.
How We’re Priced
Commission-only, no recovery, no fee. We’re paid a percentage of what we actually recover for you — never a flat audit fee regardless of outcome. This is the standard model across the reimbursement-recovery industry, and it aligns our incentive with yours: we only make money when you do.
For a live catalogue with meaningful FBA volume, an initial audit alone typically surfaces enough unclaimed reimbursements to make the exercise worthwhile even before considering ongoing monthly recovery.
Frequently Asked Questions
Q: How much money can I actually recover?
A: It varies by account size and history, but industry data suggests the typical unaudited FBA seller is leaving roughly $1,500-$3,000 per year unclaimed. Larger catalogues with more shipment volume often recover meaningfully more.
Q: How long do I have to file an FBA reimbursement claim?
A: As of the October 2024 policy update, most lost/damaged inventory claims must be filed within 60 days, down from a much longer prior window. Removal-order claims currently have a separate, longer window of around 90 days. Always confirm the current deadline for your specific case in Seller Central, since Amazon has adjusted these windows more than once.
Q: Why is my reimbursement so much lower than what I expected?
A: Amazon shifted to calculating many lost/damaged reimbursements based on manufacturing cost rather than your selling price, effective around March 2025. High-margin products are affected the most, since the gap between manufacturing cost and selling price is largest for them.
Q: Does Amazon automatically reimburse me, or do I have to file manually?
A: Amazon’s automated system now resolves a meaningful share of straightforward lost/damaged cases without a manual claim. However, automation is pattern-based and consistently misses fee overcharges, return discrepancies, and edge cases — which is where a manual audit adds the most value.
Q: What documentation do I need for a claim?
A: Typically transaction IDs, order numbers, and timestamps at minimum. Certain claim types also require proof of delivery, a signed bill of lading, or packing slips as supporting evidence.
Q: What’s the difference between lost inventory and damaged inventory claims?
A: Lost inventory covers units that entered Amazon’s network but never reached a customer or came back to you. Damaged inventory covers units that were physically damaged at a fulfillment center, in transit between centers, or during handling, and were never restored to sellable condition.
Q: Can I get reimbursed for a customer return that was never actually returned?
A: Yes — if a customer is refunded but the item never makes it back into your inventory (or arrives and isn’t correctly restocked), that discrepancy is claimable as a return-value case.
Q: What are those adjustment codes (E1, E3, E7, M) I see in my inventory report?
A: These are Amazon’s internal codes for specific inventory-loss reasons: E1 is damaged, E3 is damaged specifically at a fulfillment center, E7 means removed by the customer, and M means missing/lost. A negative adjustment with one of these codes and no matching reimbursement is a claim candidate.
Q: How do you get paid?
A: Commission-only, based on what we actually recover — there’s no flat audit fee and no charge if a case doesn’t result in a successful claim.
Q: Can fee overcharges really add up to meaningful money?
A: Yes — a single mismeasured or misclassified product can silently overcharge you on every unit shipped for months before anyone notices, since it shows up as a slightly-too-high per-unit fee rather than an obvious one-time error.
Q: Is there a risk to my account from filing reimbursement claims?
A: No — filing accurate, well-documented reimbursement claims is a normal, expected part of using FBA and carries no account-health risk. The risk profile only changes if claims are vague, exaggerated, or not genuinely supportable, which is why documentation quality matters.
Q: Should I still audit my account if Amazon’s automated system is handling reimbursements now?
A: Yes. Automation catches straightforward lost/damaged patterns but consistently misses fee overcharges, incorrectly restocked returns, and other edge cases — a periodic manual audit still finds meaningful additional recovery.
Q: How often should I audit my FBA account for reimbursements?
A: Monthly is ideal, given the compressed 60-day claim window — waiting a full quarter risks losing eligibility on cases from the earlier part of that period.
Q: Do I need Brand Registry or a Professional account to file reimbursement claims?
A: A Professional Seller account is required to access FBA services generally, but Brand Registry enrollment isn’t a specific requirement for filing standard reimbursement claims.
Q: What happens if my claim gets denied?
A: Many legitimate claims are initially denied on a documentation technicality rather than a genuine ineligibility. A well-documented follow-up or escalation frequently succeeds where the first submission didn’t.
