When sending inventory to Amazon FBA, one of the most common concerns sellers face is a shipment discrepancy. This happens when the number of units Amazon receives does not match what was originally recorded in the shipment plan.
It can be a small issue—or something that temporarily affects your stock levels and sales.
What is a shipment discrepancy?
A shipment discrepancy occurs when Amazon finds a difference between:
- What you said you sent (shipment plan)
- What Amazon actually received and scanned
This can be a shortage (fewer units received) or an overage (more units received than expected).
What Amazon does when a discrepancy is found
When Amazon detects a mismatch, they follow a verification process before making adjustments:
- The shipment is placed under review in their system
- Units are re-counted and re-scanned where needed
- Items are checked against barcode labels and carton contents
- The inventory record is updated once the investigation is complete
In many cases, discrepancies are resolved automatically after reconciliation. However, this process can take time depending on warehouse workload and shipment size.
What causes shortages or overages?
Common reasons include:
- Packing errors during preparation
- Miscounted inventory before shipping
- Mixed SKUs in cartons
- Scanning issues at the fulfilment centre
- Damaged or unscannable labels
Even small preparation mistakes can lead to mismatches.
Why this matters for sellers
A discrepancy can temporarily affect:
- Available stock on Amazon
- Listing visibility if inventory shows as low or unavailable
- Cash flow if units are not correctly received
This is why accurate prep and clear carton labelling are critical before sending stock.
How to reduce shipment issues
To minimise discrepancies, sellers often:
- Double-check unit counts before dispatch
- Use proper labelling and barcode placement
- Separate SKUs clearly in cartons
- Work with experienced prep services
This is where a reliable fba prep australia 3pl service australia provider becomes valuable, ensuring shipments are prepared correctly before they reach Amazon.
