TL;DRFBA reimbursement for lost inventory is Amazon's obligation to compensate a seller when units are confirmed lost or destroyed inside the Amazon fulfilment network – a category that includes warehouse misplacements, inbound shipment shortfalls, and disposal errors. On Amazon DE, the mechanics are largely the same as on other EU surfaces, but German-language documentation requirements, EU consumer-law context, and Amazon's evolving automated reconciliation tools mean the procedural path has specific friction points. Sellers who understand what the reimbursement claim process actually requires – and where it tends to stall – are in a materially better position than those who wait for Amazon to act first.

FBA reimbursement for lost inventory: what changed and what to do

A seller wakes up to a reconciliation report showing a gap between units shipped and units available. The inventory is gone – not sold, not returned, just absent. Amazon's automated system may have already flagged a credit. Or it may not have. Either way, the clock on the reconciliation window is running, and the balance sitting in the seller's disbursement queue is wrong.

That situation has become more common, not less, as fulfilment volume on Amazon DE has grown. And the process for recovering what is owed has grown more layered at the same time. This briefing explains what FBA reimbursement for lost inventory actually covers on Amazon DE, how the procedural path works in practice, and where sellers typically lose ground – either by waiting too long, filing on the wrong evidence, or accepting an automated calculation without checking it.

What FBA reimbursement for lost inventory actually covers

An FBA reimbursement for lost inventory covers units that Amazon receives into its network but that disappear before the transaction that would normally close the loop – sale, return, or removal order.

In practice, the categories that generate the most claims on Amazon DE are: inbound shipment discrepancies (units shown as received short of what was shipped); warehouse loses (units that vanish after check-in and never appear in available, reserved, or unfulfillable inventory); and disposal or destruction errors (units that Amazon disposed of or destroyed without the seller's instruction, or in excess of what was authorized). A fourth category – units lost between a customer return and the warehouse return queue – overlaps with the FBA reimbursement process for damaged inventory and follows slightly different documentation logic.

What the reimbursement does not cover is equally important to understand. Units that were sold and then subject to an A-to-z Guarantee claim already have a separate credit path. Units that a seller voluntarily removed and then reported missing sit in a different queue. The distinction matters because filing under the wrong category is one of the most common reasons a claim is rejected at the first automated review stage.

On Amazon DE specifically, the reimbursement value is calculated in euros, using a formula Amazon applies to the product's average sales price. Sellers frequently dispute that formula because it can undervalue items that are priced higher than their historical average or items with thin inventory history on the DE surface. That dispute is part of the claim, not a separate process – which is why understanding the calculation basis before filing saves significant back-and-forth later.

How Amazon's reconciliation process changed – and what that means for sellers

Amazon has progressively moved FBA reimbursement calculations toward automated reconciliation, shifting the burden of identifying discrepancies partly back onto sellers.

For several years, third-party audit tools identified discrepancies and sellers filed claims manually. Amazon then announced changes to its reimbursement policy that narrowed the look-back window for manual claims and altered the evidence required to support them. The direction of travel – shorter windows, greater reliance on Amazon's own data, and less automatic crediting for discrepancies a seller identifies late – has continued.

For Amazon DE sellers, this creates two practical problems. First, if the seller's internal inventory tracking is not reconciled against Amazon's reports on a regular basis, the window to file a valid claim may close before the discrepancy is even noticed. Second, where Amazon's automated system has already issued a reimbursement, sellers sometimes assume the matter is closed – without verifying that the automated credit covered the full discrepancy or used the correct valuation.

In matters we handle, a recurring pattern is a seller who received a partial automated reimbursement, accepted it as final, and only discovered months later – during an account-level audit ahead of a deactivation or a disbursement hold – that a significant portion of the original discrepancy was never credited. At that point, the look-back window may have expired, which is why early and regular reconciliation is not optional.

The change to look-back periods is a [VOLATILE] area – Amazon has adjusted it more than once, and the period in force for any given seller's claim depends on when the loss occurred and what the policy said at that time. We check the applicable policy window as a first step before advising on whether a claim is still open.

The realistic procedural path on Amazon DE

The procedural path for an FBA reimbursement claim on Amazon DE runs through Seller Central, requires specific documentation at each stage, and escalates if the automated response is inadequate.

The sequence, in practice, looks like this. A seller identifies a discrepancy by reconciling their inventory report against shipment confirmations, removal confirmations, and sales data. They open a case in Seller Central, citing the specific FNSKU or shipment ID at issue, and providing the reconciliation evidence. Amazon's automated or first-tier response either credits the full discrepancy, credits a partial amount, or denies the claim.

If the response is a partial credit or denial, the seller escalates by providing additional documentation – typically a shipping confirmation from the carrier, a signed proof of delivery to the Amazon fulfilment centre, or an Amazon Partnered Carrier report if the inbound was done through Amazon's own carrier program. For Amazon DE inbounds, this may mean German-language carrier documentation, and the case handler may not always engage fluently with documents not in English – a friction point we see regularly in our practice.

If escalation within Seller Central does not resolve the claim, the seller's next options are a formal dispute through the mechanism available under the Business Solutions Agreement (BSA) applicable to their account, or a complaint via the internal complaint-handling mechanism that Amazon is required to maintain under the Platform-to-Business (P2B) Regulation for EU sellers. The P2B Regulation gives sellers a right to a statement of reasons for adverse decisions and a functioning internal complaint path – which is relevant here because an unjustified reimbursement denial is an adverse commercial decision that should attract that right.

Where claims most often go wrong

The most common failure mode is filing too late or on incomplete evidence – and then accepting the denial without escalating.

Sellers on Amazon DE who rely entirely on Amazon's automated reimbursement system without cross-checking against their own records will, over time, leave money unclaimed. Amazon's system is not designed to catch every discrepancy, and its valuation of units it does credit is not always conservative in the seller's favor.

A second failure mode is filing on the right discrepancy but the wrong evidence category. A unit lost after inbound check-in requires different documentation than a unit lost during a removal order. Using the wrong supporting document – or providing a document that covers a shipment globally rather than the specific FNSKU in question – results in a denial that looks final but is actually re-fileable with the correct paperwork.

A third issue specific to Amazon DE is the valuation dispute. Where a seller believes Amazon's automated credit undervalues the lost unit – because the pricing formula uses a historical average that does not reflect the item's actual market price on DE at the time of loss – the seller can and should challenge the valuation as part of the claim. This requires presenting a price history or comparable listing data, and it takes a second escalation that most sellers do not pursue.

The seller who handled this situation well – a mid-size electronics accessories distributor on Amazon DE (fall 2025) – had maintained a monthly reconciliation spreadsheet that tracked each FNSKU against the Amazon inventory ledger. When they came to us after a partial automated credit, we identified three separate discrepancy categories in the same reporting period that had been collapsed into one claim and partially denied. We separated the claim streams, filed the correct evidence for each category, and pressed the valuation dispute on the highest-value SKUs. The recoverable balance was materially larger than the initial automated credit had suggested.

The seller's decision points and trade-offs

The core decision is whether to pursue the full discrepancy actively or accept what Amazon's automated system has already offered.

That is not always an obvious call. If the discrepancy is small and the documentation gaps are large, the cost of escalation – in time and, if legal help is involved, fees – may exceed the recovery. If the discrepancy is significant or if there is a pattern of underreimbursement across multiple periods, escalation almost always pays.

The second decision is timing. Waiting to accumulate multiple discrepancies before filing a consolidated claim can work if the look-back window permits, but it also increases the risk that older discrepancies fall outside the recoverable period. Filing on a rolling basis as discrepancies are identified is the more defensible approach, even if the per-claim amounts are smaller.

The third decision is route. A seller who has been denied twice within Seller Central is facing a choice between the BSA dispute path and the P2B complaint path. Those are not mutually exclusive, but they have different audiences and different timelines. The BSA path – which may involve a Notice of Dispute and, depending on the account's BSA version, a pre-arbitration demand – is appropriate where the amount is substantial and the documentary case is strong. The P2B path is appropriate where the seller needs a formal statement of reasons and intends to use that document as the basis for a further challenge or a regulatory complaint to a national authority.

If a prior attempt to claim or escalate has already been denied, it is worth having the file reviewed before assuming the matter is closed. We regularly see denial letters that are, on close reading, non-final or procedurally incorrect – which opens the claim back up. For more on what to do after a reimbursement denial, the page on FBA reimbursement denial: what changed and what to do covers the escalation options in detail.

A second situation that illustrates the trade-off decision well: a household goods brand selling across Amazon EU surfaces (including DE) in spring 2026 received a disbursement that was lower than expected. An internal audit identified a combination of undervalued reimbursements across two quarters and a reserve held without a clear posted reason. We mapped every held balance and reserve, separated the reimbursement claims by category and period, and pressed the disbursement and reimbursement claims through the applicable dispute paths. The disbursement resumed on the standard cycle, and the reimbursement amounts were adjusted upward after the valuation evidence was presented.

What is still uncertain

Amazon's automated reimbursement policy – specifically the look-back window and the valuation formula – is a volatile area that has changed more than once and may change again.

Sellers should not assume that the policy that applied when they first sold on Amazon DE is still in force for claims they are filing now. The BSA version applicable to a given seller's account may also affect what dispute paths are available. We check the applicable policy version as a first step in any reimbursement review.

The P2B Regulation's internal complaint pathway is also evolving in practice. Amazon has updated its processes for EU sellers several times, and the quality and speed of the statement-of-reasons process varies. A seller who filed a P2B complaint a year ago and received no substantive response may find that a current filing, properly framed, generates a different result – particularly where the Digital Services Act's transparency obligations add procedural weight.

Whether the BSA's dispute-resolution mechanism available to a given Amazon DE seller requires informal resolution before escalation, and what that informal resolution period looks like in practice, depends on the BSA version that applies to the account. We check that first before advising on which dispute path is the right tool.

The honest answer to "what is uncertain" is: the exact look-back window, the valuation methodology Amazon will apply to a given claim, and the dispute path that will be most efficient for a given seller's account and discrepancy amount. Those are the variables we assess first in any new matter.

Frequently asked questions

How long does resolving FBA reimbursement for lost inventory usually take on Amazon DE?

Timeline varies significantly depending on the complexity of the discrepancy, the quality of the documentation, and whether escalation beyond the first Seller Central response is needed. A straightforward single-shipment claim with clean carrier documentation can close in a matter of weeks. A multi-period claim involving valuation disputes and a P2B complaint may take several months. The most reliable way to shorten the timeline is to file on correct, complete evidence the first time – because re-filing after an unnecessary denial adds weeks at minimum.

What are the main risks if I handle FBA reimbursement for lost inventory alone?

The main risks are filing outside the look-back window, filing under the wrong evidence category, and accepting an automated credit without verifying that it covers the full discrepancy at the correct valuation. A partial credit accepted as final is very difficult to reopen later. Sellers who handle claims alone also frequently miss the valuation dispute step entirely, leaving money on the table even in cases where the unit count is agreed. The P2B and BSA escalation paths are also procedurally specific, and a misstep at those stages can close options that were otherwise open.

Do I need a lawyer for FBA reimbursement for lost inventory?

For small, isolated discrepancies with clean documentation, a seller with good internal records can often file and recover without legal help. Attorney involvement becomes more valuable – and the cost typically justifies itself – where the claim involves multiple SKUs or periods, a valuation dispute, a denial that needs to be challenged, or a dispute that has reached the BSA or P2B escalation stage. In our practice, the matters where a lawyer adds the most is not at the initial filing but at the escalation stage, where procedural errors are hardest to recover from.
