How to Get Amazon FBA Reimbursed for Lost or Damaged Inventory

Amazon's vast fulfilment network handles an enormous, constant volume of inventory movement every single day, and across that scale, individual units genuinely do get lost, damaged, or mishandled somewhere along the way — more often than most sellers assume, and more often than gets automatically caught and reimbursed. The money involved is real: SKUs with meaningful volume can accumulate hundreds or thousands of pounds in unclaimed reimbursements over the course of a single year, sitting just a straightforward, repeatable audit and claim process away from actually being recovered.

If you haven't audited your FBA reimbursements recently, message me directly on WhatsApp — I help sellers set up inventory auditing and reimbursement processes that recover real, meaningful money that's often just sitting unclaimed in Amazon's own transaction records, waiting to be found.

Where lost and damaged inventory actually happens

• Within a fulfilment centre — a unit is misplaced, damaged during handling, or lost during a warehouse transfer, and Amazon's inventory count no longer matches what was actually sent in.
• In transit between fulfilment centres, when Amazon redistributes stock across its network — inventory lost during this internal movement is a legitimate reimbursement category, distinct from anything the seller did.
• Customer returns processed incorrectly — Amazon refunds the customer, but the returned item is never actually received back into inventory, or is received in a damaged, unsellable condition without the seller being properly notified or reimbursed for the loss.
• Removal or disposal errors — a unit intended for return to the seller or for disposal is handled incorrectly, resulting in an inventory loss that doesn't match what was actually requested.

None of these specific scenarios are the seller's own fault, which is precisely why Amazon's formal reimbursement policy exists in the first place — but the policy generally requires the seller to identify and, in some cases, actively claim the discrepancy, rather than guaranteeing every single case is caught and resolved automatically.

Why automatic reimbursement doesn't catch everything

Amazon's systems do automatically reimburse a real share of confirmed lost and damaged inventory cases. But gaps happen for a few understandable reasons: a discrepancy that falls just outside Amazon's automated detection logic, a reconciliation timing issue between different internal systems, or a case that technically qualifies but simply wasn't flagged by the automated process for reasons that aren't always visible to the seller. This is the gap an active audit process is specifically designed to catch — not because Amazon is deliberately withholding money, but because a fully automated system across an operation this large inevitably misses some genuine cases.

Where to actually find discrepancies

• Inventory Adjustments report — shows adjustments Amazon has made to your recorded inventory, including for damage, loss, or found inventory, and is a direct source for identifying cases that may already be resolved versus ones that still need a claim.
• Reimbursements report — shows reimbursements Amazon has already issued, useful for confirming what's been covered automatically so you're not duplicating a claim.
• Inventory Ledger — a detailed, transaction-level record of every inventory movement, which is the most thorough source for manually reconciling units received against units sold, returned, and currently in stock to find unexplained gaps.

Comparing these three sources against each other, for a given SKU and time period, is how a genuine, unreimbursed discrepancy gets identified — a gap that shows up in the Inventory Ledger but doesn't appear in the Reimbursements report is a strong candidate worth investigating further.

The reimbursement categories sellers most commonly miss

Some discrepancy types are more likely to go unclaimed than others, simply because they're less obvious to spot without specifically looking:

• Customer returns marked as received but never actually restocked — Amazon processes the customer's refund, and the inventory system shows the unit as returned, but it never re-enters sellable (or even unsellable/disposed) inventory in a way that matches what was expected. This gap sits specifically at the intersection of the Returns report and the Inventory Ledger, and is easy to miss if only one of the two is checked.
• Warehouse damage during the "removal" or disposal process itself — a unit a seller requested to have removed or disposed of can be damaged or lost during that specific handling step, which is a distinct discrepancy from ordinary in-warehouse damage and is worth checking for separately if you've made removal or disposal requests.
• Inbound shipment discrepancies — a shipment sent to Amazon where the received quantity doesn't match what was actually shipped, which can be a warehouse receiving error rather than a later in-warehouse loss, and is checked through shipment reconciliation reports rather than the general Inventory Ledger alone.
• Long-term storage fee errors — while not strictly a "lost or damaged" reimbursement, incorrect long-term storage fee charges (for inventory that shouldn't have qualified, or calculated against an inaccurate age) are a related category of Amazon billing error worth checking during the same audit process, since the same report-reconciliation habit catches both.

Building a checklist covering all of these categories, rather than only the most obvious "lost in warehouse" case, is what separates a thorough audit from one that recovers only the easiest, most visible discrepancies while leaving quieter ones unclaimed.

A practical auditing process

1. Pull the Inventory Ledger for the period you want to audit — a rolling quarterly review is a reasonable cadence for most sellers, though higher-volume sellers may benefit from checking more frequently.
2. Reconcile units received, sold, returned, and currently in stock for each SKU, looking for gaps that don't have an obvious, already-explained cause.
3. Cross-check any gaps against the Reimbursements report, to confirm whether Amazon has already automatically covered that specific discrepancy.
4. For genuine, unreimbursed gaps, file a claim through Seller Central's support case process, referencing the specific discrepancy with supporting data pulled directly from Amazon's own reports.
5. Track claim outcomes, so you have a clear record of what's been claimed, resolved, and paid — both for your own accounting and in case a claim needs to be followed up or escalated.

A worked example of an audit finding real, unclaimed money

A home and garden seller with a moderate-sized catalogue (around 40 active SKUs) ran a first-time reimbursement audit after not having checked systematically in over a year. Reconciling the Inventory Ledger against units actually received and sold revealed a cluster of discrepancies concentrated in a handful of SKUs that had gone through a fulfilment centre transfer several months earlier — units that had never been reimbursed automatically, despite the loss clearly showing in Amazon's own transaction records.

After filing claims for each identified discrepancy, referencing the specific ledger entries as supporting evidence, the seller recovered just over £1,100 across the affected SKUs — money that had been sitting unclaimed simply because no one had specifically gone looking for it. The seller subsequently moved to a quarterly audit cadence, which has since caught smaller discrepancies before they accumulated to a similar scale.

Comparing manual auditing against a dedicated reimbursement tool

Approach	Best suited to	Trade-off
Manual audit (Seller Central reports)	Smaller catalogues, lower order volume	No additional cost, but genuinely time-consuming as scale grows
Third-party reimbursement auditing service	Larger catalogues, higher order volume	Typically charges a percentage of recovered funds, but scales far better with size
Hybrid — periodic manual spot-checks plus occasional deeper audit	Most growing sellers	A reasonable middle ground before committing to a dedicated tool

There's no universally correct choice — the right approach scales with catalogue size and order volume, and it's reasonable to start manual and move to a dedicated tool once the time cost of manual reconciliation clearly outweighs a service fee on recovered funds.

Common mistakes in claiming FBA reimbursements

• Never auditing at all, on the assumption that Amazon's automatic system catches everything — it catches a meaningful share, not all of it.
• Auditing once and never again, rather than treating this as an ongoing, recurring process — new discrepancies happen continuously as inventory keeps moving through the network.
• Missing the claim filing window by discovering a discrepancy too late, which is a strong argument for a regular audit cadence rather than an occasional, irregular one.
• Filing claims without specific supporting data, which slows down or weakens a claim compared to one that references exact ledger entries and dates.
• Not tracking claim outcomes, losing visibility into which claims were resolved, denied, or need follow-up.

What to do if a claim is denied

A denied claim isn't necessarily the end of the process — if you believe the supporting evidence genuinely supports the discrepancy, following up with additional detail or escalating through Seller Support is a reasonable next step, rather than assuming a first denial is final. Keeping thorough documentation from the outset makes this follow-up considerably more straightforward than trying to reconstruct evidence after the fact, and a specific, data-backed follow-up is generally treated more seriously than a repeated, generic request to "please reconsider."

Why reimbursement policy is worth checking directly rather than relying on old information

Amazon has adjusted its reimbursement policies — including claim windows, eligible categories, and the specific process for filing — more than once over time, which means guidance that was accurate a year or two ago may no longer fully reflect current policy. Before relying on a specific claim window or eligibility rule, it's worth confirming the current version directly in Seller Central's help documentation rather than working from memory or outdated general advice, including anything in this guide beyond the general categories and process described above.

Building reimbursement auditing into normal operations

The sellers who consistently recover the most unclaimed reimbursement money treat this as a standing part of financial operations, not a one-off exercise done occasionally when someone remembers to check. A durable approach typically includes:

• A fixed audit schedule (quarterly is a reasonable default for most catalogue sizes), calendared in advance rather than left to whenever there's spare time.
• A consistent method for cross-referencing the three main reports (Inventory Ledger, Inventory Adjustments, Reimbursements) each time, so the process doesn't need to be reinvented from scratch on every audit.
• A simple log of claims filed and their outcomes, both for financial record-keeping and to build a pattern of evidence useful if a dispute or escalation is ever needed.
• A clear decision point for when catalogue size or order volume justifies moving from manual audits to a dedicated third-party reimbursement service, rather than continuing manual audits well past the point they're the most efficient approach.

Treated this way, reimbursement auditing becomes a small, predictable, recurring task rather than an occasional scramble — and for most sellers with meaningful order volume, it reliably recovers more than enough to justify the time or cost involved.

Where this fits into broader inventory and account management

Reimbursement auditing isn't an isolated task — it connects directly to the same underlying inventory accuracy that also affects account health metrics like Pre-fulfilment Cancel Rate (see the full Account Health guide for how inventory accuracy and account performance are linked) and, for sellers running multiple channels from one stock pool, the same inventory sync discipline that prevents overselling. A seller who's genuinely on top of their inventory data — accurate counts, regular reconciliation, clear records — tends to find reimbursement auditing considerably faster and more thorough than one approaching it as a standalone, occasional exercise, simply because the underlying data discipline is already in place day to day, rather than needing to be hurriedly assembled specifically for the audit itself.
