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

Your Inventory Performance Dashboard displays your IPI score, along with key influencing factors. Be sure to check your IPI score regularly, a low score could lead to overage fees and limit your ability to send more inventory. See details ›
