In the retail industry, velocity typically refers to the speed at which products move through the supply chain or off the shelves and into the hands of consumers. It is a key performance indicator used to measure the efficiency of inventory turnover. High velocity indicates that products are selling quickly, which is often desirable for retailers to prevent overstocking and ensure a steady cash flow. Monitoring velocity helps retailers optimize inventory levels, identify popular products, and streamline supply chain processes to meet customer demand effectively.
