FBA Reimbursements in 2026: How to Recover the Money Amazon Owes You

When you send inventory into Fulfillment by Amazon, you hand Amazon responsibility for storing, picking, packing, and shipping your units. Things go wrong at scale: boxes go missing in the warehouse, units get crushed on a conveyor, a customer return is never restocked, or an FBA fee is billed on the wrong measured weight. When the error is Amazon's, you are typically owed money back. That money is an FBA reimbursement — a credit Amazon issues for inventory or fees it lost, damaged, or over-charged.

Historically, reimbursements were one of the most overlooked line items in an FBA business. Amazon does surface some of them automatically, but plenty of discrepancies slipped through unless a seller went looking. What changed the calculus is a set of policy updates Amazon rolled out across 2024 and 2025 that reshaped both how much you get back and how long you have to ask.

Two shifts matter most, as of 2026. First, effective March 31, 2025, Amazon updated its FBA inventory reimbursement policy to reimburse warehouse-lost-or-damaged inventory based on the product's manufacturing (sourcing) cost rather than its selling price — you can accept Amazon's estimated cost or submit your own cost data. Second, the manual claim windows were tightened: reporting on the policy changes that took effect around October 23, 2024 in the US indicates that many FBA claim types dropped from roughly 18 months to about 60 days from the date of the issue. Both figures should be confirmed for your account and marketplace in Seller Central, since Amazon can revise terms at any time.

"Reimbursements used to be the money you found in an old coat pocket — nice, but easy to ignore. After the 2024 to 2025 policy changes, the window to claim is short and the payout math changed. Now it is an operating discipline, not an afterthought."

The upside for sellers is that the process is now more automated than it used to be. Reporting on the same 2024 updates indicates Amazon proactively reimburses many warehouse-lost-and-damaged items without a manual request. The catch: auto-reimbursement does not catch everything, and when it misses, the shorter claim window means a slow-moving seller can simply run out of time. That gap — between what Amazon pays automatically and what you are actually owed — is exactly what reimbursement tools and services exist to close.

Not every loss is claimable, and the basis for the payout depends on when and how the problem happened. The table below groups the most common reimbursable discrepancies and how they are generally handled as of 2026. Treat it as a directional guide — exact claim windows, documentation rules, and payout basis are set by Amazon and can differ by marketplace, so confirm the current terms for your account in Seller Central.

You do not need software to file reimbursements. Every seller can pull the reports, reconcile the numbers, and open cases directly in Seller Central at no cost beyond their own time. For a small catalog with clean inbound records, doing it yourself can be entirely reasonable — especially now that Amazon auto-reimburses more warehouse losses than it used to.

The trade-off is time and coverage. Auditing an FBA account thoroughly means cross-referencing several reports every month, matching them against inbound records and invoices, and re-checking within a claim window that is now much shorter than it once was. Reimbursement tools and services automate the audit: they scan your account for discrepancies, assemble the supporting documentation, and either surface the claims for you to file or file them on your behalf through Seller Support. Most operate on a contingency model — a commission taken only from money they successfully recover — which industry coverage in 2026 generally puts somewhere in the range of roughly 10 to 25 percent, with no upfront fee. Confirm the current rate and terms directly with any provider before you sign up.

If you are weighing a tool or service, three things are worth checking as of 2026:

• Audit coverage. Which discrepancy types does it actually check — warehouse loss and damage only, or also fee and dimension errors, returns, and inbound shortages?
• Success or commission model. Contingency pricing aligns incentives, but the percentage varies. Ask what happens if Amazon later reclaims a reimbursement — some providers reverse their commission if that occurs.
• Amazon TOS compliance. Amazon has clear rules about how third parties may access your account and file cases. Favor providers that describe how they stay within Amazon's terms and that never ask you to hand over full login credentials outside of Amazon's approved access methods.

One pitfall to avoid regardless of approach: do not double-file. If a service or your own manual claim requests a reimbursement that Amazon has already auto-issued, you can create duplicate cases, and repeatedly filing invalid or duplicate claims can put your account standing at risk. A good process — or a good tool — reconciles what has already been paid before it opens anything new.

Because the claim windows are shorter than they used to be, the whole game is catching discrepancies quickly and filing before they expire. Here is a practical monthly sequence that works whether you do it by hand or let a tool run it for you.

The recurring theme is documentation and timing. Reimbursements are a legitimate part of running an FBA business — you are recovering money for Amazon's own operational errors — but the burden of proof and the clock are both on you. Whether you keep it in-house or hand it to a specialist, the goal is the same: a repeatable monthly audit that no longer lets valid claims quietly expire.
