The FBA Reimbursement Money Most Sellers Never Claim
Amazon owes more sellers more money than they realize — but the 2025 rule changes mean the old playbook no longer works. Here is what to do now.
Every month, Amazon absorbs money that belongs to sellers: units lost on the way into a fulfillment center, inventory damaged in the warehouse, customer returns that never make it back to sellable stock, and fee overcharges from wrong dimensions. Individually they're small. Over a year, they add up to real money.
But the rules changed dramatically in 2025, and most advice online is still describing the old system. If you're working from a guide written before 2025, you're working from a map that no longer matches the territory.
First, the claim window collapsed from 18 months to just 60 days (effective October 2024). Second, from March 2025, reimbursements for inventory lost or damaged before a customer order are based on your manufacturing cost, not the retail price — which can cut payouts by 50–75% on high-margin products.
The single most important thing to do right now
Upload your real manufacturing cost for every SKU. Under the new policy, if you don't provide your sourcing cost, Amazon estimates it — and that estimate is typically 20–30% below what you actually paid. For inventory lost before a customer order, that estimate is what you'll be reimbursed. Uploading accurate cost data is now the difference between fair recovery and leaving money on the table on every single claim.
Find the cost-of-goods upload in your reimbursement/inventory-defect settings and enter accurate per-unit manufacturing costs for all active SKUs. Keep supplier invoices on hand — documentation requirements are stricter now.
Where the money still hides
Amazon now auto-reimburses many warehouse lost-and-damaged cases without you filing anything. That's genuinely helpful — but it does not eliminate the need to audit. Auto-reimbursements can be missed, miscalculated, or based on Amazon's low cost estimate. And several categories still require you to file manually and on time.
| Claim type | How it works now | Window |
|---|---|---|
| Warehouse lost / damaged | Mostly auto-reimbursed; file manually if missed | 60 days |
| FBA customer returns | File manually — returned but not restocked | 45–105 days |
| Removal / disposal | Always filed manually | 15–75 days |
| Fee / dimension overcharges | Dispute with measurements | Ongoing |
A realistic monthly routine
Because the window is now 60 days, the old habit of an annual audit guarantees you miss claims. A monthly cadence catches issues before they expire:
- Confirm cost data is current
Check that every active SKU has an accurate manufacturing cost on file before anything else.
- Pull inventory adjustments
Filter for reason codes that indicate Amazon-side loss or damage, and cross-check against auto-reimbursements you actually received.
- Reconcile inbound shipments
Match units sent vs. units received; flag anything still short after the reconciliation window.
- Check returns
Cross-reference refunded orders against returned-to-sellable inventory.
- File within the window
Submit legitimate claims with supporting reports and invoices — before the 60 days lapse.
When a tool earns its cost
At low volume, the manual routine above is enough. Once you're moving meaningful inventory, the math shifts — a tighter window plus cost-based payouts means missed claims are both more likely and harder to recover. This is exactly the kind of rule-based, time-sensitive work software handles better than a human auditing at midnight.
Full suites like Helium 10 include reimbursement features alongside broader research tools, which makes sense if you'd use the rest anyway. Dedicated recovery services also exist, usually taking a percentage of what they recover — which aligns their incentives with yours. See our research-suite reviews to weigh the options.
Reimbursement money is real and it's yours — but the window is short and the payout now depends on your cost data. Build the monthly routine, upload your costs, and act before claims expire.
