Improve Inventory Turns, or IIT (pronounced eye-eye-tee), is a procurement concept that refers to the frequency in which inventory is purchased, used, and reordered. In other words, it’s a measure of how quickly turnover happens with inventory storage and sales. The goal is to minimize the amount of dead stock—or products that get stuck in the warehouse and don’t move—by finding ways to purchase the right amount of items at the right time. With proper planning, IIT helps businesses manage their supply chain more efficiently and maximize profits while reducing unnecessary costs.
