Refunzo runs a comprehensive scan across 21 checkpoints spanning shipments, inventory, payments, fees, and refunds.
You get a detailed report with a substantiated estimate of what Amazon owes, broken out by checkpoint.
File the claims
Authenticate a card. It's charged nothing at this point, it's only held on file.
Refunzo logs a support case with Amazon per checkpoint, substantiates it with the retrieved evidence, and tracks it individually.
Refunzo follows up until Amazon resolves the case, appealing denials where the evidence supports it.
Amazon credits your bank directly. Only then are you charged 15% of that payout, capped at $5,000 per account.
What Does Refunzo Check in Your Amazon Account?
Refunzo runs an AI-assisted Amazon FBA reimbursement audit across shipments, inventory, payments, fees and refunds. It checks for missing inbound units, lost or damaged inventory, reimbursement underpayments, fee overcharges, missing returns and reimbursement reversals.

|---|---|
| Shipments | Missing units, receiving shortages, lost inbound shipments, proof-of-delivery mismatches |
| Inventory | Lost units, warehouse damage, removal-order issues, inventory adjustments |
| Payments | Underpaid reimbursements, reversals, unpaid cases |
| Fees & overcharges | Dimension errors, storage fee errors, referral fee issues, surcharges |
| Refunds & returns | Missing returns, damaged returns, condition downgrades |
The 21 checkpoints
Every checkpoint Refunzo runs against your account, with what Amazon does wrong and what gets recovered.
What Should Amazon FBA Sellers Know About Reimbursements in 2027?
Amazon reimburses most lost or damaged inventory at what the product costs you, not what you sell it for. Add your real costs in Seller Central, or Amazon will use its own lower estimate. Then file quickly, because many claim windows are as short as 60 days.
How Does Amazon Calculate FBA Reimbursements?
If Amazon loses or damages your inventory in its warehouse, it owes you a reimbursement. Since March 2025, Amazon calculates that amount from your product’s manufacturing cost, not its retail selling price.
How Long Do Sellers Have to File an Amazon FBA Reimbursement Claim?
Most lost or damaged inventory claims must be filed within 60 days. Other claim types have different windows: customer-return claims can generally be filed between 45 and 105 days, and some removal-order claims allow longer.
Does Amazon Automatically Reimburse Every FBA Loss?
No. Amazon automatically reimburses some straightforward fulfillment-center losses, but not every discrepancy. More complex issues, such as inventory mismatches, returns, removals, fee errors and reimbursement reversals, may still need review or a manual claim.
Proof of delivery retrieval
Most inbound-shipment claims get denied for missing documentation, not because the loss isn't real. Refunzo retrieves proof of delivery directly from the carrier so the evidence is already attached when the case is filed.
