What is IPI?

Your inventory performance index, or IPI score, combines three months of historical sales, inventory levels, and costs into a single metric. This metric helps you identify how well your inventory is performing in FBA, areas to improve, and determines if you are eligible for unlimited storage.

Measuring your performance
