Rate of Sale measures how quickly a product is selling over a given time period. It is calculated as the average number of units sold per day, week, or month. Monitoring ROS helps identify fast-moving versus slow-moving products, influencing replenishment and markdown strategies. High ROS indicates healthy demand and low inventory risk. Inventory optimization systems track ROS trends to determine stocking strategies, reduce dead stock, and improve cash flow. Real-time ROS insights can also help in forecasting during promotions or launches.
