You detect retail returns fraud by looking for mismatches and repeat patterns. You start with a few basic checks that catch the most problems:
- Match the returned item to what went out of your warehouse by checking the outbound item detailsLi
- Check serial numbers for electronics and other serial-tracked products
- Confirm accessories for kits and high-value items (chargers, cables, inserts)
- Flag common patterns: empty box, swapped item, used item returned as new
- Track repeat behavior across accounts, addresses, or order patterns
