Amazon FBA Reimbursement Tool 2026: Free Lost & Damaged Inventory Analyzer

An Amazon reimbursement tool analyzes your Seller Central reports to find cases where Amazon owes you money — typically for lost inventory, damaged goods, customer returns that were never returned, or other FBA errors. Instead of manually digging through thousands of rows, the tool does the heavy lifting and shows you exactly what to claim.

Because Amazon’s warehouses process millions of items daily, and mistakes happen constantly. Studies suggest Amazon loses or damages 1-3% of FBA inventory. For a seller moving $100,000/year through FBA, that’s $1,000-$3,000 in potential claims. Most sellers never file because they simply don’t know the money is there. A reimbursement tool finds it for you.

Yes, completely free. No trial period, no credit card required, no “freemium” upsells. We built this tool to help Amazon sellers and drive traffic to our FBA prep services. The tool itself costs you nothing.

Paid services typically charge 15-25% of recovered funds and require access to your Seller Central account. Our tool is free, processes data locally (we never see your information), and gives you the same analysis. The only difference is you file the cases yourself instead of them doing it — which takes about 5 minutes per case.

You’ll need at minimum two reports: the Inventory Ledger (found under Reports → Fulfillment → Inventory) and the Reimbursements Report (under Reports → Fulfillment → Payments). For better analysis, also grab your FBA Customer Returns report and FBA Inventory snapshot. We provide step-by-step instructions for downloading each one.

Amazon’s reimbursement policy typically covers the last 18 months. We recommend downloading reports for the full 18-month period to catch everything you’re eligible to claim.

Yes. Our FBA reimbursement tool supports Amazon USA, UK, Canada, Germany, France, Italy, Spain, Netherlands, India, Japan, Australia, Mexico, UAE, and more. Simply select your marketplace and upload your reports.

Usually under 60 seconds. The processing happens entirely in your browser, so speed depends on your computer and report size. Most sellers see results within 30 seconds.

Absolutely. Your reports are processed 100% locally in your browser. Nothing is uploaded to our servers. We literally never see your data. Once you close the page, the data is gone.

Lost inventory refers to units that Amazon cannot account for. These are items that entered FBA warehouses but have no record of being sold, returned, removed, or currently in stock. Amazon should reimburse you for these — but often doesn’t unless you file a case.

Lost inventory is missing with no explanation — it simply vanished from Amazon’s system. Damaged inventory was physically damaged by Amazon’s warehouse operations (not by customers). Both are eligible for reimbursement, but they’re tracked separately because the claim process differs slightly.

A reversal happens when Amazon initially pays you a reimbursement, then later takes the money back. Sometimes this is legitimate (they found the inventory), but often it’s an error. Our tool flags all reversals so you can review them and dispute any that seem incorrect.

We calculate values based on prices found in your reports — either from your FBA Inventory snapshot or from previous reimbursement amounts. These are estimates. Amazon may value items differently when you file a case, but our numbers give you a solid starting point.

We assign High, Medium, or Low priority based on the dollar value at stake. High priority items (typically $100+) should be addressed first. This helps you focus your time on the cases that matter most.

The tool identifies what you’re owed — you then file cases with Amazon Seller Support. Go to Seller Central → Help → Contact Us, select “Fulfillment by Amazon” → “FBA Issue,” and submit your claim with the ASIN, FNSKU, quantity, and dates from our report. Most cases are resolved within 5-7 days.

Yes. Click “Download CSV Report” to get a spreadsheet with all findings. This makes it easy to track your cases and reference specific details when filing with Amazon.

Amazon doesn’t publish official limits, but we recommend filing 5-10 cases per day to avoid triggering any automated flags. Start with your highest-value items.

It happens. If you believe the denial is incorrect, you can escalate by asking for a supervisor review or filing a new case with additional documentation. Having the detailed data from our tool often helps in escalation.

The Inventory Ledger is the most comprehensive record of every inventory movement in your FBA account — receipts, shipments, adjustments, returns, removals, and more. It’s the foundation for identifying discrepancies. The old “Inventory Adjustments” report was merged into this.

Yes. We’ve tested with reports containing over 50,000 rows. Large files may take a bit longer to process (up to 2 minutes), but the tool handles them fine. Just be patient while the progress bar completes.

No installation required. The tool runs entirely in your web browser. Just visit the page and start uploading.

Any modern browser works — Chrome, Firefox, Safari, Edge. We recommend keeping your browser updated for best performance.

Technically yes, but we recommend using a desktop or laptop. Downloading reports from Seller Central and uploading CSV files is much easier on a computer.

Amazon sellers recover an average of $2,000-$5,000 in their first analysis. It takes 5 minutes. It’s completely free. Your data stays private.
