Amazon FBA Reimbursements: The Claims Process for Lost and Damaged Inventory

Amazon FBA reimbursements compensate eligible sellers when inventory is lost or damaged while under Amazon’s control. But reimbursement isn’t guaranteed simply because inventory disappears.

While Amazon handles many fulfillment-center reimbursements automatically, brands are still responsible to monitor inventory, confirm reimbursements, and file manual claims when needed.

The key is identifying where and when the inventory discrepancy occurred. An inbound shipment shortage follows a different process from inventory lost inside an Amazon fulfillment center. Each also comes with its own filing window.

For operators, this makes reimbursement management less of a claims task and more of an inventory-control process.

What Counts as Lost or Damaged FBA Inventory?

Not every missing unit falls into the same reimbursement category.

Two of the most common situations are:

• Inventory shipped to Amazon but not fully received
• Inventory lost or damaged after being received into an Amazon fulfillment center

That distinction matters because Amazon uses different workflows, eligibility rules, and deadlines for each.

An inbound shipment may show fewer received units than your shipping records indicate. Before you can file a claim, Amazon generally needs time to receive and reconcile the shipment.

A fulfillment-center issue happens later. Amazon has already received the inventory, but the unit is subsequently reported lost or damaged during fulfillment-center operations.

Customer returns and removal orders have separate reimbursement rules. Those cases should be tracked separately rather than grouped into the same process.

The operational mistake is treating every missing unit as one generic Amazon reimbursement problem. First identify the inventory event. Then determine which policy and claim window apply.

Automatic Reimbursements vs. Manual FBA Claims

Amazon has expanded proactive reimbursement for many inventory losses and damages inside its fulfillment network.

In practical terms, Amazon may identify an eligible event and issue reimbursement without requiring the seller to open a manual case.

That reduces administrative work, but it doesn’t eliminate the need for oversight.

Brands should reconcile reported losses against actual reimbursements. If Amazon identifies three units as lost, the process shouldn’t end until you can confirm whether those three units were reimbursed, recovered, or otherwise resolved.

A manual FBA reimbursement claim may still be necessary when:

• Amazon reports inventory as lost or damaged but no reimbursement follows
• An inbound shipment discrepancy becomes eligible for investigation
• Amazon requests additional documentation
• The original reimbursement decision doesn’t match the documented inventory event

Automation changes how claims are processed. It doesn’t change the need to verify the outcome.

The Amazon FBA Reimbursement Claims Process

A consistent claims process reduces missed deadlines and duplicate work.

1. Identify the inventory discrepancy

Start with the underlying inventory event.

Review shipment records, inventory adjustments, defect records, and reimbursement transactions. Identify the affected FNSKU, quantity, shipment, or fulfillment-center adjustment.

Then confirm Amazon hasn’t already reimbursed the inventory.

This prevents teams from opening cases for events that Amazon has already resolved automatically.

2. Determine the correct claim type

Classify the issue before filing anything.

Common categories include:

• Shipment-to-Amazon discrepancy
• Fulfillment-center lost inventory
• Fulfillment-center damaged inventory
• Customer-return or removal-order issue

Correct classification determines the workflow, documentation requirements, and deadline.

3. Confirm the filing window

Amazon’s reimbursement deadlines are category-specific.

For fulfillment-center inventory reported lost or damaged, manual claims must generally be filed within 60 days of the reported event.

Shipment-to-Amazon claims have a longer window. Amazon currently states that these claims must be submitted within nine months after verified delivery.

If you disagree with Amazon’s initial claim decision, its October 2025 policy update established a 90-day window from the initial claim for re-evaluation requests.

Those differences make a single generic “reimbursement deadline” unreliable. The claim category needs to be established first.

4. Gather the supporting records

The documentation required depends on the event.

Useful records may include the affected FNSKU, unit quantity, shipment ID, transaction records, inventory adjustments, and prior reimbursement activity.

Amazon may also request sourcing-cost documentation.

For qualifying less-than-truckload or full-truckload inbound shipment investigations, proof of delivery may also be required.

The goal is to build enough documentation to connect the physical inventory movement to the discrepancy being claimed.

5. Submit and track the claim

Use the applicable Seller Central reimbursement or shipment reconciliation workflow.

Once submitted, track more than the case number. Record the quantity claimed, filing date, Amazon’s decision, reimbursement amount, and any later adjustment or reversal.

If Amazon’s determination conflicts with your records, use the applicable re-evaluation process before the deadline expires.

A claim isn’t fully resolved when it’s submitted. It’s resolved when the financial and inventory records agree.

Because these windows differ, reimbursement audits should happen frequently enough to catch issues before eligibility expires.

How Amazon Calculates FBA Reimbursements

One of the most important changes to FBA reimbursement policy is how Amazon values inventory.

A reimbursement doesn’t necessarily equal the product’s retail selling price.

For qualifying shipment-to-Amazon, removal, and fulfillment-center operations claims occurring before customer fulfillment, Amazon’s current policy uses the seller’s sourcing cost.

The updated valuation policy took effect on March 31, 2025.

Sourcing cost reflects what the brand paid to acquire or manufacture the product, not the revenue it expected to generate from selling it.

That distinction can materially affect reimbursement amounts.

Amazon also provides a Manage Your Sourcing Cost function within its Inventory Defect and Reimbursement portal. Brands should maintain those costs before a discrepancy occurs rather than trying to reconstruct them during a claim.

Current policy also caps reimbursement at $5,000 per eligible FBA unit.

For brands selling high-value inventory, that cap creates another reason to evaluate how much financial exposure sits inside Amazon’s fulfillment network.

Why FBA Reimbursements Should Be an Inventory-Control Process

The bigger operational risk is allowing unresolved inventory discrepancies to accumulate without a repeatable review process.

A 60-day filing window leaves limited room for brands that only examine FBA adjustments during quarterly financial reviews. By the time someone investigates an old discrepancy, the claim window may already be closed.

Reimbursement management should connect several records in one recurring process:

• Shipment receipts
• Inventory adjustments
• Reported defects
• Automatic reimbursements
• Sourcing costs
• Open cases
• Claim and re-evaluation deadlines

Someone also needs clear ownership. When responsibility is divided between operations, finance, agencies, and marketplace managers, unresolved cases can sit untouched because everyone assumes someone else is handling them.

A stronger process reviews inventory defects on a defined cadence, reconciles automatic reimbursements, and maintains sourcing-cost records by SKU.

The objective is to identify legitimate losses, recover eligible inventory value, and keep marketplace financial reporting accurate.

Treat Reimbursements as Part of FBA Operations

Amazon FBA reimbursement management works best when it’s built into normal inventory operations.

Identify what happened. Match the event to the correct claim type. Confirm the filing deadline. Maintain the documentation Amazon may require. Then reconcile the final reimbursement against the underlying inventory event.

That process matters even as Amazon automates more reimbursements.

Automation can initiate the reimbursement. It can’t replace the brand’s responsibility to verify that inventory and financial records ultimately match.

For operators managing meaningful FBA volume, that discipline turns reimbursements from a reactive Seller Central task into a repeatable inventory control.
