Amazon FBA Inventory Reimbursement: Seller Guide

Amazon sellers rely on Fulfillment by Amazon (FBA) to store inventory, process orders, and deliver products to customers. While the service allows businesses to streamline their operations, it also places a significant portion of inventory management in Amazon's hands.

What happens when Amazon loses your inventory, damages your products, or refuses to reimburse you for missing merchandise?

For sellers, these problems can result in substantial financial losses, particularly when hundreds or thousands of units are involved. Fortunately, Amazon maintains an FBA inventory reimbursement policy that allows eligible sellers to recover certain losses.

However, reimbursement is not automatic in every situation. Sellers must understand Amazon's eligibility requirements, filing deadlines, and dispute resolution procedures to protect their businesses.

What Is Amazon FBA Inventory Reimbursement?

Amazon FBA inventory reimbursement is the process through which eligible sellers receive compensation or replacement inventory when products are lost or damaged under circumstances covered by Amazon's policies.

Under Amazon's FBA Inventory Reimbursement Policy, Amazon may replace eligible lost or damaged inventory with the same product or provide financial reimbursement.

For example, a seller may ship 500 units to an Amazon fulfillment center, only to discover that Amazon recorded 450 units as received. Another seller may discover that products previously recorded in their inventory were damaged during fulfillment center operations.

These situations may qualify for reimbursement, but eligibility depends on the circumstances of the loss and the applicable Amazon policy.

Amazon has also introduced automatic reimbursements for certain inventory losses. Nevertheless, sellers should continue monitoring their accounts because some discrepancies require manual investigation and claims.

When Does Amazon Reimburse Sellers for Lost or Damaged Inventory?

Amazon distinguishes between different types of inventory losses depending on when and where the problem occurs.

Inventory Lost During Shipment to Amazon

When sellers send inventory to an Amazon fulfillment center, discrepancies may arise between the number of units shipped and the number Amazon records as received.

For example, a seller may ship 200 units but discover that only 180 were accounted for after the shipment was processed.

If the discrepancy qualifies for investigation, the seller may be able to submit a reimbursement claim through Seller Central.

Amazon's Shipment to Amazon Claims Policy explains the procedures for investigating inbound shipment discrepancies.

Inventory Lost or Damaged at an Amazon Fulfillment Center

Inventory can also go missing or become damaged after Amazon has received it.

This may occur during storage, internal movement, or other fulfillment center operations.

Amazon tracks certain losses through its Inventory Defect and Reimbursement portal and Inventory Ledger report. If an eligible loss is not automatically reimbursed, the seller may need to submit a manual claim.

The applicable requirements are explained in Amazon's Fulfillment Center Operations Claims Policy.

Customer Return Discrepancies

Customer returns can create additional inventory complications.

A customer may fail to return a refunded product, return an incorrect item, or send back merchandise that is damaged or incomplete.

However, not every unsellable return qualifies for reimbursement. Eligibility depends on the circumstances, including whether the loss falls within Amazon's reimbursement policy.

Sellers should examine return records, product condition information, and any available supporting evidence before submitting a claim.

Removal Order Discrepancies

Sellers may request the removal of inventory from Amazon's fulfillment network when products are no longer needed, cannot be sold, or require inspection.

If products are lost, damaged, or incorrectly processed during removal, the seller may have grounds to request reimbursement.

Because removal order claims are subject to separate procedures, sellers should review the applicable requirements before submitting a request.

How Do You Recover Lost Inventory From Amazon FBA?

Recovering lost Amazon FBA inventory begins with identifying the discrepancy and determining whether Amazon has already taken corrective action.

Step 1: Review Your Inventory Reports

Sellers should regularly examine their Seller Central inventory records to identify discrepancies.

Depending on the situation, relevant records may include the Inventory Ledger, shipment reconciliation information, inventory adjustments, reimbursement transactions, and customer return reports.

These records can help determine whether inventory was received, misplaced, damaged, reimbursed, or otherwise adjusted.

Sellers should compare Amazon's records against their own shipping documentation and inventory management systems.

Step 2: Determine Whether Amazon Has Issued a Reimbursement

Before filing a manual claim, sellers should determine whether Amazon has already reimbursed the affected inventory.

Amazon provides automatic reimbursements for certain qualifying losses, particularly those identified during fulfillment center operations.

Sellers can review reimbursement activity through the relevant Seller Central reports.

If the discrepancy remains unresolved, the next step is to determine which claim process applies.

Step 3: Gather Supporting Documentation

A successful reimbursement claim depends on accurate documentation.

Depending on the circumstances, sellers may need to provide supplier invoices, proof of purchase, shipment tracking records, delivery confirmations, packing information, product photographs, and correspondence with Amazon.

For inbound shipment discrepancies, documentation demonstrating the quantity shipped and delivered may be especially important.

For returned merchandise, photographs of the received product, packaging, shipping labels, and identifying information may help establish whether the correct item was returned.

The evidence should directly address the discrepancy Amazon is investigating.

Step 4: Submit the Appropriate Reimbursement Claim

Once the seller has identified the loss and gathered supporting documentation, they can submit a claim through the applicable Seller Central workflow.

The submission should clearly identify the affected inventory, explain the discrepancy, and provide evidence supporting the requested reimbursement.

Different claim categories have different requirements. A claim involving inventory lost during inbound shipment processing may not follow the same procedure as a claim involving damage at a fulfillment center.

Sellers should confirm that they are using the correct process before submitting their claim.

Step 5: Monitor Amazon's Response

After submitting the claim, sellers should monitor Seller Central for updates, requests for additional documentation, or a reimbursement decision.

Amazon may approve the claim, request further evidence, or deny reimbursement based on its investigation.

If the claim is denied, sellers should review the explanation carefully to determine whether additional review is available.

How Long Do Amazon Sellers Have to File FBA Reimbursement Claims?

Amazon establishes different filing deadlines depending on the type of inventory loss.

Understanding these deadlines is important because missing an applicable claim window may prevent a seller from obtaining reimbursement.

Shipment to Amazon Claims: Up to Nine Months

Under Amazon's Shipment to Amazon Claims Policy, sellers may file a claim once the shipment is marked as eligible for investigation in the shipping workflow.

The claim must be submitted no later than nine months after the verified delivery date to an Amazon fulfillment center or a third-party facility operated on Amazon's behalf.

For example, if a shipment was verified as delivered on January 15, the nine-month deadline would generally fall on October 15 of the same year.

However, sellers should not assume that they must wait until the end of that period. The claim can be submitted once Amazon identifies the shipment as eligible for investigation.

For more information, review Amazon's official Shipment to Amazon Claims Policy.

Fulfillment Center Operations Claims: 60 Days

When inventory is lost or damaged after being received into Amazon's fulfillment network, a different deadline applies.

Amazon's Fulfillment Center Operations Claims Policy requires sellers to submit eligible manual claims within 60 days after the item is reported lost or damaged in the Inventory Defect and Reimbursement portal or Inventory Ledger report.

This deadline is distinct from the nine-month period applicable to qualifying inbound shipment claims.

Sellers should regularly review their inventory reports so they can identify discrepancies before the applicable claim window closes.

For additional details, consult Amazon's Fulfillment Center Operations Claims Policy.

Customer Returns and Removal Order Claims

Customer returns and removal order disputes are subject to their own filing windows.

The applicable deadline may depend on the customer refund date, removal shipment creation date, delivery date, or another event identified in Amazon's policy.

Because these requirements differ from inbound shipment and fulfillment center claims, sellers should consult the relevant category-specific provisions of Amazon's FBA Inventory Reimbursement Policy before filing.

Maintaining accurate records and reviewing inventory discrepancies regularly can help sellers avoid missing important deadlines.

How Does Amazon Calculate FBA Inventory Reimbursements?

Recovering lost inventory is only one part of the reimbursement process. Sellers must also understand how Amazon calculates the amount they may receive.

In March 2025, Amazon changed its reimbursement methodology for certain inventory lost or damaged before a customer order.

Under the revised policy, reimbursement for qualifying pre-order inventory losses is generally calculated using the product's sourcing cost rather than its retail selling price.

Sourcing cost refers to the amount paid to obtain or manufacture the product. Under Amazon's policy, this generally excludes expenses such as shipping, handling, and customs duties.

For example, a product may retail for $50 but cost the seller $15 to purchase from a supplier. Under the applicable sourcing-cost methodology, the reimbursement may be based on the $15 acquisition cost rather than the $50 retail price.

Amazon may use its own estimated sourcing cost or consider documentation provided by the seller.

Sellers should review their recorded costs and maintain supplier invoices or other acceptable proof-of-value documentation to support the amount claimed.

Amazon distinguishes these pre-order losses from certain post-order losses, which may be valued using the original sales price minus applicable fees.

For more information, review Amazon's FBA Inventory Reimbursement Policy.

What Happens if Amazon Denies Your FBA Reimbursement Claim?

A denied reimbursement claim can create additional frustration for sellers who believe their inventory was lost or damaged while under Amazon's control.

However, a denial does not necessarily mean that every available option has been exhausted.

Sellers should begin by reviewing Amazon's stated reason for rejecting the claim.

For example, Amazon may determine that the inventory was not eligible for reimbursement, that the documentation was insufficient, or that the claim was submitted outside the applicable filing window.

If Amazon permits further review, sellers should address the specific reasons for the denial and provide additional evidence where appropriate.

Repeatedly submitting the same information without addressing Amazon's findings may not resolve the underlying issue.

In cases involving substantial inventory losses, sellers may also benefit from evaluating whether the dispute raises contractual issues beyond the ordinary reimbursement process.

Can Amazon Sellers Pursue Arbitration for Unresolved Inventory Disputes?

When an inventory reimbursement dispute remains unresolved, sellers may consider whether formal dispute resolution is appropriate.

Amazon's Business Solutions Agreement governs many aspects of the contractual relationship between Amazon and third-party sellers, including the resolution of certain disputes.

Depending on the applicable agreement and the circumstances, arbitration may be an available or required method of resolving a contractual disagreement.

Arbitration is a formal legal proceeding in which an independent arbitrator considers the evidence and arguments presented by the parties.

Unlike a standard Seller Central reimbursement request, arbitration requires sellers to identify a legal or contractual basis for their claim.

For sellers experiencing significant financial losses, repeated reimbursement denials, or unresolved contractual disputes, legal counsel can help evaluate whether arbitration is appropriate.

Sellers considering formal proceedings can also review our guide on How to File Arbitration Against Amazon.

Not every reimbursement dispute warrants arbitration. Sellers should consider the amount in dispute, the available evidence, the governing agreement, and the potential costs before pursuing formal legal action.

Are Amazon FBA Inventory Violations the Same as Reimbursement Disputes?

Although inventory reimbursement disputes and inventory-related policy violations can both affect Amazon sellers, they are not necessarily the same issue.

A reimbursement dispute generally concerns compensation for inventory that has been lost, damaged, or improperly accounted for.

An inventory-related policy violation may instead involve allegations concerning product authenticity, restricted products, preparation requirements, or other compliance obligations.

These violations can potentially result in listing restrictions, inventory removal, or account enforcement measures.

The appropriate response depends on the circumstances.

A seller seeking reimbursement for missing inventory may need to provide shipment records and evidence of loss. A seller facing an inventory-related policy violation may need to address Amazon's compliance concerns through the appropriate appeals process.

Understanding the distinction can help sellers determine which procedures apply to their situation.

How Can Amazon Sellers Protect Their Businesses Against Inventory Losses?

While sellers cannot prevent every inventory discrepancy, maintaining accurate records can reduce the risk of unresolved losses.

Businesses should establish procedures for reconciling inbound shipments, reviewing inventory adjustments, monitoring reimbursement transactions, and preserving supplier documentation.

Regularly reviewing Seller Central reports can also help identify discrepancies before applicable filing deadlines expire.

For sellers managing large inventories, relatively small discrepancies can accumulate into substantial losses over time.

Consistent monitoring and organized documentation can make it easier to identify potential reimbursement claims and respond when Amazon requests additional information.
