Understanding Inventory Discrepancies

Inventory discrepancies occur when the stock levels shown in your Seller Central account don't match what Amazon's fulfilment centres have recorded. This can happen during receiving, transfers between warehouses, or through various operational processes. The key is systematic investigation and resolution.

Receiving discrepancies can be frustrating, but learning from each other makes us all stronger. We want to hear from you:

• What's your biggest challenge with receiving discrepancies—missing units, damaged items, or something else?
• Have you discovered a prep or labelling technique that's eliminated discrepancies for your shipments?
• What documentation practices have helped you successfully resolve cases with Seller Support?

Your Investigation Toolkit

Start with Your Reports: Check your Inventory Adjustments report in Seller Central to identify when and where discrepancies occurred. Look for adjustment codes that indicate warehouse lost (M), warehouse damaged (D), or customer return issues (C-Ret). These codes tell you what type of discrepancy you're dealing with.

Review Your Shipment History: Compare what you sent against what was received. Check the "Reconcile" tab for each shipment to see if there are receiving discrepancies. Sometimes items are still in the receiving process and will appear as "in transit" rather than available.

Monitor Transfer Records: If you use multiple fulfilment centres, verify that inter-warehouse transfers completed properly. Ensure transfer IDs are closed and inventory moved correctly between locations.

Resolution Tactics That Work

For Missing Inventory: If items show as received but aren't appearing in your available inventory, check if they're stuck in "pending" status. This can happen when there are data synchronisation issues between systems. Allow 24-48 hours for processing, as some adjustments take time to reflect.

For Overage Situations: When you have more inventory than expected, verify whether this resulted from a previous reimbursement. Check your Reimbursements report to ensure you're not double-counting units that were already compensated.

For Damaged or Lost Units: Amazon automatically investigates and reimburses for warehouse-caused damage or loss. You can track these through the Inventory Ledger report. If you believe you're owed a reimbursement that hasn't been processed, you can open a case with Seller Support, but ensure you have supporting documentation.

Best Practices for Prevention

Accurate Shipment Creation: Ensure your shipment plans match exactly what you're sending. Include accurate box counts, weights, and contents. Proper labelling prevents receiving errors that lead to discrepancies.

Regular Reconciliation: Review your inventory reports weekly rather than waiting for problems to escalate. The Inventory Age report and Manage FBA Inventory page help you spot issues early.

Maintain Documentation: Keep records of what you ship, including box contents, weights, and carrier tracking. This documentation is invaluable when investigating discrepancies.

When to Escalate

If you've investigated thoroughly and still can't resolve a discrepancy, contact Seller Support with specific details: the FNSKU, quantity affected, shipment ID, and timeline of events. The more precise information you provide, the faster they can investigate
