A Perpetual Inventory System is a stock tracking system that uses real-time data to provide instant visibility of inventory levels. This type of inventory management system utilizes data from point-of-sale (POS) systems and barcode scanners to keep track of product movement. By having up-to-date information about inventory, the perpetual system allows for efficient and accurate decisions regarding restocking needs, purchasing trends, and more. Utilizing a perpetual inventory system can help businesses maximize profitability, optimize resources, and maintain customer satisfaction.
