Introduction
You’re shipping thousands of units, managing dozens of SKUs, and watching your revenue scale but your profit isn’t keeping match. One often-overlooked reason: Amazon owes you money you’ve never claimed.
Inventory gets lost in fulfilment centres. Returns get processed incorrectly. FBA fees get calculated on the wrong dimensions. Amazon’s systems don’t automatically catch all of these, and they certainly don’t automatically pay you back. That’s the job of Amazon reimbursement services — and for high-volume sellers, it’s not an optional admin task.
This blog breaks down where FBA reimbursements come from, why they’re so frequently left unrecovered, how Amazon’s 2025 policy change affects what you’re owed, and how automated reimbursement tools help sellers recover lost revenue with accuracy.
Key takeaway:
- Inventory losses, fulfillment mistakes, and fee overcharges happen regularly inside Amazon’s network and the responsibility for claiming that money back falls on sellers, not Amazon.
- High-volume FBA sellers face the greatest exposure because errors scale proportionally with order and shipment volume.
- Amazon’s March 2025 reimbursement policy change shifted payouts from selling price to manufacturing cost, reducing the value of many claims.
- Manual reimbursement tracking across multiple Amazon reports doesn’t scale and leads to missed deadlines.
- Automated Amazon reimbursement services identify, document, and file claims on your behalf — recovering revenue that would otherwise vanish quietly from your P&L.
How Amazon FBA Errors Create Unrecovered Revenue for Sellers
Every time Amazon receives, stores, transfers, or ships your inventory, there’s a chance something goes wrong. Each error represents a potential reimbursement claim that Amazon won’t raise on your behalf.
Lost and Damaged Inventory
Units go missing during inbound shipments, bin transfers, or simply disappear from stock counts. Warehouse damage happens at receiving, during storage, and at pick-and-pack. Amazon is supposed to reimburse these losses — but the claim doesn’t file itself.
Overcharged FBA Fees
Amazon calculates fulfilment fees based on recorded product dimensions and weight. When those measurements are wrong, you overpay every single month. A slightly inflated dimension that pushes a product into the next fee tier compounds silently over time.
Customer Return Errors and Refund Discrepancies
Amazon often issues customer refunds before the item is returned. If it never comes back — or arrives damaged — the seller absorbs the loss. Return-related discrepancies are among the most common and most underclaimed categories in FBA reimbursements.
Why Amazon Doesn't Automatically Reimburse Every Eligible Claim
Many sellers assume that if Amazon makes an error, Amazon will fix it. That assumption is wrong.
Amazon operates at huge scale. Their systems do catch some errors automatically, and automatic reimbursements do appear in your payments ledger from time to time. But a significant portion of eligible claims require action from the seller. You can read more about how Amazon reimbursements work in our detailed breakdown.
Here’s what falls on you:
- Identify the discrepancy — Amazon won’t flag most errors on your behalf. You need to spot them first.
- Gather documentation — Lost inventory claims require cross-referencing shipment records against received quantities. Fee overcharges require auditing product measurements against Amazon’s recorded data.
- Reconcile multiple reports — These aren’t quick checks. They involve pulling and matching several report types from Seller Central.
- Meet hard deadlines — Most FBA reimbursement claims must be filed within 60–90 days of the event. Miss the window and the claim is gone permanently, regardless of how clear the error was.
Amazon’s 2025 Reimbursement Policy Change — What Sellers Need to Know
In March 2025, Amazon shifted reimbursements for lost and damaged FBA inventory from estimated selling price to manufacturing cost. For sellers with healthy margins, this means significantly lower payouts per claim.
Accurate COGS documentation is now critical. Without it, Amazon may apply a default valuation that underestimates your actual cost. Sellers using an Amazon reimbursement service that integrates with P&L data are better positioned to defend their cost basis.
Why High-Volume Sellers Are Most Exposed
High-volume selling creates high-volume exposure: more SKUs, more shipments, more returns, and more inventory movements mean more opportunities for errors — and more opportunities for those errors to go unnoticed.
Example:
- A seller processing 750 orders a month has a very different reimbursement footprint than one processing 10,000. At scale, even a 1–2% leakage rate on revenue through unrecovered FBA claims represents a material amount of money that simply never shows up on your P&L.
- Consider a seller doing $1000,000 in annual revenue. A conservative 1.5% in unrecovered reimbursements amounts to $15,000 a year. Most high-volume sellers have no idea this money exists, because it doesn’t appear as a line item anywhere — it just quietly doesn’t arrive.
Manual oversight becomes practically impossible beyond a certain volume. There’s no spreadsheet workflow that efficiently tracks every shipment discrepancy, fee overcharge, and return error across a growing catalogue without someone spending hours every week on it.
The Real Cost of Managing Reimbursements Manually
The appeal of doing it yourself is understandable — you want control and you want to avoid fees. The problem is the operational cost of doing it well.
The Reports You Need to Cross-Reference
Accurate FBA reimbursement management requires pulling and reconciling at least three separate Amazon report types:
- Inventory Adjustments Report — tracks unit-level discrepancies across your FBA stock
- Reimbursements Report — shows what Amazon has already paid out automatically
- Payments / Ledger Reports — records all financial transactions against your account
Each report uses different data structures, different time windows, and different identifiers. For sellers with multiple ASINs and active inbound shipments, a single manual reconciliation cycle can take four to six hours.
The 60-Day Window Problem
Amazon’s claim deadlines are strict — and easy to miss:
- Most lost inventory claims must be filed within 60 days of the event
- Return-related claims have their own separate timelines
- Fee overcharge claims follow yet another schedule
In practice, many sellers only check for reimbursements when something looks obviously wrong. By then, several windows may already have closed — and that revenue is gone permanently.
What Amazon Reimbursement Services Do — And How to Evaluate One
A quality Amazon reimbursement service automates the entire workflow. Here’s what that covers:

What Amazon Reimbursement Services Do — And How to Evaluate One
A quality Amazon reimbursement service automates the entire workflow. Here’s what that covers:
- Scanning your account data continuously for discrepancies
- Identifying claimable events across all major error categories
- Preparing supporting documentation for each claim
- Submitting claims through Amazon’s systems
- Tracking them through to resolution
The best services run continuously, not as a one-time audit. New errors occur every month, and claims need to be filed before windows close.
What to Look for in an Amazon Reimbursement Service
Not all reimbursement tools are built equally. Here’s what matters when evaluating one:
- Coverage breadth — Does the service identify all major error categories: lost inventory, damaged inventory, overcharged fees, and return discrepancies? Narrow tools miss significant claim volume.
- Amazon policy compliance — Amazon has updated its reimbursement policies multiple times, including significant changes in 2025. The service should be current and file claims in line with Amazon’s seller policies.
- Pricing model — Commission-only models align incentives correctly — you pay only when money is recovered. Flat monthly fees apply regardless of results.
- Reporting visibility — Can you see what was identified, filed, and recovered? Transparency matters for trust and for connecting reimbursements to your broader P&L.
- Profitability integration — Recovered reimbursements are revenue. A service that connects to your Amazon profit tracking dashboard gives you a complete picture, not just a separate claim report.

Conclusion
Reimbursements aren’t a bonus. They’re revenue you’ve already earned — quietly subtracted by fulfilment errors, fee miscalculations, and return mistakes.
For high-volume sellers, the exposure grows with every shipment. Manual tracking doesn’t scale, and Amazon’s 2025 policy changes have made accurate documentation more critical than ever.
Amazon reimbursement services exist to close that gap — finding the errors, filing the claims, and making sure recovered money shows up where it belongs in your profit.
