Inventory Days Of Supply (IDOS) is a key performance indicator used to measure inventory management success. It reflects the average number of days it takes for an item in inventory to be sold or consumed. To calculate IDOS, you simply divide the amount of inventory on hand by the average daily rate of sales or consumption over a given period. As a business owner, tracking your IDOS is essential for monitoring your inventory levels and understanding how long it takes to turn items into cash. With this information in hand, you can then make strategic decisions regarding when to restock and shift purchasing strategies accordingly. Investing in smarter inventory management means better profitability for your business!
