FBA inventory moves through several events before and after a customer order. When sellers review only the final inventory total, losses, adjustments, return differences, and unresolved shipment movements can remain hidden inside separate reports.
The Direct Answer
Discrepancies are commonly missed where records must be reconciled across stages rather than read from one dashboard. Important areas include inbound shipment receiving, fulfilment-centre transfers, warehouse damage, customer returns, removals, disposal activity, and reimbursements that were issued, reversed, or valued differently than expected. Eligibility always depends on Amazon’s current policy and the evidence available for the event.
When the Answer Changes
- An inbound shortage requires different evidence from a warehouse-damaged unit.
- A customer-return discrepancy must be separated from a normal refund or unsellable return.
- A reimbursement already issued may require a valuation check rather than a duplicate claim.
- Automated reimbursements can reduce manual work, but they do not remove the need for reconciliation.
Practical Diagnostic Checklist
- Reconcile shipped quantities against received quantities for closed inbound shipments.
- Review inventory adjustments by reason code and event date.
- Match lost or damaged events against reimbursements already posted.
- Check customer refunds against returned and restocked units.
- Review removal and disposal orders for completed, cancelled, and missing units.
- Confirm each potential claim remains within current eligibility and submission requirements.
- Store invoices, shipment records, tracking, and case communication in one audit trail.
Screenshot or Account Evidence
Add an anonymized reconciliation sheet that traces one SKU through shipped, received, adjusted, reimbursed, and unresolved quantities. Use a verified closed case and remove seller, shipment, SKU, and financial identifiers.
Decision Table
| Situation | What it usually means | Recommended action |
|---|---|---|
| Shipment received short | Inbound units may be missing or under investigation | Confirm shipment status and required documentation before filing |
| Damaged event without a matching credit | A reimbursement may not have posted or may be ineligible | Match event and reimbursement identifiers, then check policy |
| Refund without a returned unit | The return may still be in transit or unresolved | Review return status and applicable timing before action |
| Credit posted and later reversed | Amazon may have found or reclassified inventory | Trace both entries before opening another claim |
Mistakes We Commonly Find
- Submitting a claim before checking whether Amazon already reimbursed the event.
- Treating every inventory adjustment as reimbursable.
- Using a single report without matching event and reimbursement records.
- Opening duplicate cases for the same discrepancy.
- Waiting so long that records and supporting documents become difficult to retrieve.
Recommended Action
Create a repeatable monthly reconciliation process rather than relying on occasional claim searches. Match events across shipment, inventory, return, removal, and reimbursement records. Document why each discrepancy appears eligible, confirm it has not already been resolved, and submit only supported cases under the current marketplace policy.
Frequently Asked Questions
Does every missing FBA unit qualify for reimbursement?
No. Eligibility depends on the event, responsibility, supporting records, current policy, and whether Amazon has already resolved the discrepancy.
Can reimbursement software find every case?
Automation can identify patterns and candidates, but complex movements, reversals, and evidence requirements may still need review.
Why can a reimbursement differ from the selling price?
Amazon applies its reimbursement valuation rules rather than simply paying the current retail price.
How often should FBA accounts be reconciled?
A consistent monthly review is practical for many sellers, with more frequent checks for high-volume or high-value inventory.
