Why FBA sellers keep leaving
reimbursements on the table.
Amazon's 60-day claim window changed the math
Amazon compressed the reimbursement window from 18 months to 60 days across most FBA categories. You can't afford to audit once a quarter anymore — issues you don't catch within 60 days are gone for good.
The sourcing cost problem no one talks about
Since late 2024, Amazon calculates reimbursements based on your sourcing cost — not the sale price. If you haven't entered accurate sourcing costs, Amazon uses its own estimate. That estimate is typically lower than your actual cost.
Thousands of rows, no clear signal
Reimbursement reports can contain hundreds of rows per month. Without a structured audit, you're either reviewing everything manually — or not reviewing at all. Most sellers choose the second option.
Types of FBA Reimbursements
Amazon Sellers Miss
Amazon handles millions of units daily. Errors are inevitable — and they add up. Here are the six most common reimbursement categories that go unclaimed.
Lost & Misplaced Inventory
Items disappear during warehouse transfers, receiving, or internal moves between fulfillment centers. Amazon may not flag these automatically, and the reimbursement — if issued — may not reflect your actual cost.
Damaged Inventory in Fulfillment Centers
Products damaged by Amazon warehouse staff or equipment are eligible for reimbursement. But the payout is calculated using Amazon's estimate of your item's value, which is often lower than your sourcing cost.
Customer Return Issues
A customer receives a refund but never returns the product — or returns it damaged beyond resale. Amazon is supposed to reimburse you, but these cases frequently slip through the cracks.
FBA Fee Overcharges
Incorrect product dimensions or weight in Amazon's catalog can result in higher pick-and-pack fees, storage fees, or fulfillment fees. These overcharges accumulate silently across thousands of units.
Inbound Shipment Shortages
You ship 500 units to Amazon but only 480 are checked in. The 20-unit discrepancy is your loss unless you file a claim — and the claim window is now just 60 days.
Destroyed Without Authorization
Amazon may dispose of inventory it deems unsellable without notifying you or issuing a proper reimbursement. If you didn't authorize the destruction, you're owed compensation.
Amazon's 2025 Reimbursement Policy Changes — Why Your Amazon Reimbursement Tool Matters More Than Ever
Amazon made three major changes to its FBA reimbursement policy in early 2025. Together, they fundamentally shift the economics of reimbursement recovery.
Cost-Based Reimbursement Is Now the Default
Effective March 31, 2025, Amazon no longer reimburses lost or damaged inventory based on the selling price. Instead, reimbursement is calculated using the manufacturing or sourcing cost of the item.
For most sellers, this means reimbursement payouts have dropped 60–75% compared to the previous formula. And if you haven't uploaded accurate sourcing costs to Seller Central, Amazon uses its own estimate — which is typically even lower.
This is exactly why ReimburseOps includes a missing_cost detection rule. If a reimbursement record has no matching sourcing cost, you have no way to verify whether Amazon's payout is fair. That's a flag worth investigating.
The New IDR Portal
In January 2025, Amazon launched the Inventory Defect and Reimbursement (IDR) portal — a centralized dashboard inside Seller Central that consolidates data from five different reports. It shows defects across three statuses: eligible for claim, in progress, and resolved.
The IDR portal is a step forward in transparency, but it doesn't audit your payouts. It tells you what was reimbursed — not whether the amount was correct. That's where a dedicated amazon reimbursement tool like ReimburseOps comes in: it cross-references your sourcing costs against Amazon's payouts to find gaps the IDR portal doesn't surface.
The 60-Day Claim Window Changes Everything
Amazon compressed the reimbursement claim window from 18 months to 60 days for most FBA claim types. This means sellers who audit quarterly — or not at all — are permanently losing money every month.
A monthly audit cycle is no longer optional. It's the minimum. ReimburseOps delivers results in under 60 seconds per upload, making weekly or bi-weekly audits practical even for solo sellers.
Three steps from CSV to clarity.
Upload your CSVs
Export your FBA Reimbursements report from Seller Central. Optionally upload a sourcing cost sheet with your unit costs by FNSKU or ASIN. ReimburseOps auto-detects column names — no reformatting needed.
Confirm field mapping
We suggest column mappings automatically based on your CSV headers. Review and adjust if needed — typically takes under a minute. We handle common Seller Central export formats out of the box.
Review every flag, ranked by severity
See every suspicious record with its detection rule, severity level, and the data behind the flag. Sort by severity, filter by rule type, and export a prioritized action list to share with your VA or claims service.

Missing Cost Record
A reimbursement exists but no sourcing cost can be matched by FNSKU or ASIN. Without a cost record, Amazon uses its own valuation estimate — and you have no way to verify if the payout is fair.
Under-Reimbursed Payout
Amazon paid less than 90% of your sourcing cost × quantity. The payout doesn't cover your actual unit loss. These are your highest-value claims — especially for products with meaningful sourcing costs.
Inconsistent Valuation
Amazon paid very different amounts for the same FNSKU and event type. A max/min payout ratio above 1.25 within the same group indicates inconsistent or arbitrary valuation — a strong signal that at least one payout is wrong.
Cost Definition Warning
Your sourcing cost record appears to include shipping, freight, customs, or handling — indicating a landed cost entry. Amazon's reimbursement baseline is sourcing cost only. A landed cost entry will overstate your comparison and may produce false positives in other rules.

Might Owe You
Industry data shows that Amazon FBA sellers lose 1–3% of annual revenue to fulfillment errors. Most of this goes unrecovered.
| Your Annual FBA Revenue | Estimated Annual Loss (1–3%) | Monthly Revenue at Risk (60-day window) |
|---|---|---|
| $100,000 | $1,000 – $3,000 | ~$167 per month |
| $500,000 | $5,000 – $15,000 | ~$833 per month |
| $1,000,000+ | $10,000 – $30,000 | ~$1,667 per month |
These are industry averages, not guarantees. Your actual recovery depends on your product categories, fulfillment volume, and how recently you last audited. Upload your reimbursement CSV to see your real numbers — not estimates.
Self-service audit vs. managed service — which is right for you?
Managed amazon reimbursement services file claims on your behalf. ReimburseOps tells you exactly what to claim — so you stay in control of the process and the economics.
| R ReimburseOps | Managed Services (Helium 10, GETIDA, etc.) | |
|---|---|---|
| Fee structure | $0 free / $19 mo Pro | 15–25% of recovered funds |
| You see why each record was flagged | ✓ Full rule transparency | Rarely — black-box audit |
| Sourcing cost vs. landed cost check | ✓ Built-in warning rule | Not addressed |
| Claims filed for you | ✗ You file (or delegate to VA) | ✓ Fully managed |
| Works alongside managed services | ✓ Use your audit list to guide them | — |
| Audit results in <60 seconds | ✓ Immediate on upload | Hours to days for initial report |

Frequently asked questions.
Is ReimburseOps compliant with Amazon's Terms of Service?
Yes. ReimburseOps is a read-only audit tool that works with CSV files you export from Seller Central. We never connect to your account directly and never submit claims on your behalf. All actions remain in your control. We never take a commission on recovered funds.
What CSV files do I need to upload?
You need your FBA Reimbursements report from Seller Central (Reports → Fulfillment → Reimbursements). Optionally, upload a sourcing cost sheet with your unit costs by FNSKU or ASIN. Without sourcing costs, the missing_cost and under_reimbursed rules have limited data to work with.
What is the difference between sourcing cost and landed cost?
Sourcing cost is the unit purchase price of the product itself — what you paid the supplier per unit. Landed cost includes shipping, freight, customs, and handling. Amazon's reimbursement system uses sourcing cost as the baseline. Entering landed cost as sourcing cost will overstate your comparison baseline and may produce false positives in the under_reimbursed check. The cost_definition_warning rule is designed to catch this.
How quickly can I see results?
Most audits complete in under 60 seconds after you confirm your field mapping. Results are displayed immediately with severity rankings. You can sort, filter by rule type, and drill into each record's detail view to understand exactly why it was flagged.
Can I use ReimburseOps alongside a managed reimbursement service?
Yes — and many sellers do. ReimburseOps tells you exactly which records have issues and why, ranked by severity. You can pass that prioritized export to a managed amazon reimbursement service or VA, rather than paying a 15–25% commission on everything they discover independently. You stay informed; they handle the filing.
What types of FBA reimbursement issues does ReimburseOps detect?
ReimburseOps runs four detection rules on every audit: missing sourcing cost records, under-reimbursed payouts, inconsistent valuations across the same FNSKU, and cost definition warnings for landed-cost entries. These rules cover the most common FBA reimbursement categories — including lost inventory, damaged goods, customer return gaps, fee overcharges, shipment shortages, and unauthorized destruction.
How does Amazon's 2025 cost-based reimbursement policy affect me?
Since March 31, 2025, Amazon calculates reimbursements based on your manufacturing or sourcing cost — not the sale price. If you haven't uploaded accurate sourcing costs to Seller Central, Amazon uses its own estimate, which is typically lower than your real cost. ReimburseOps's missing_cost rule flags every reimbursement record where no sourcing cost is available, so you can identify where Amazon may be using an understated estimate.
What is the Amazon IDR Portal and how does ReimburseOps work with it?
The Inventory Defect and Reimbursement (IDR) portal is Amazon's official dashboard for tracking inventory defects and their resolution status. It consolidates data from five reports into one view. However, the IDR portal shows what was reimbursed — not whether the amount was correct. ReimburseOps fills that gap by comparing Amazon's payouts against your sourcing costs to find records where you were underpaid.
How much can I expect to recover from an FBA reimbursement audit?
Recovery amounts vary by seller, but industry data suggests that Amazon FBA sellers lose 1–3% of annual revenue to fulfillment errors. Factors that affect your recovery include your product categories, fulfillment volume, how recently you last audited, and whether you've uploaded accurate sourcing costs.
