Inventory loss prevention is an operational risk managemnt strategy to reduce the discrepancy between the inventory data and the actual stock. The goal is not to eliminate the loss but to reduce the amounts of preventable loss (shrinkage). There are several common causes behind inventory loss. Thefts and frauds are common, both by employees and people outside the businesses who access the inventory. Low product qualities can also cause shrinkage in inventory because the products are damaged or deteriorate. There are also cases of administrative error, mistakes in the inventory review process, or vendor fraud. Some customers may conduct return fraud, returning items to the sellers and claiming a refund despite the items not being qualified. Sometimes, the shrinkage is recorded as “unattributed losses” because the causes cannot be determined.
