Inventory systems are tools used by businesses to track and manage their stock of products. These systems help ensure that the right amount of inventory is available at the right time, reducing the risk of overstocking or running out of items. They can be manual or automated, with software solutions often providing real-time data on inventory levels. Effective inventory systems can improve efficiency and reduce costs. They allow businesses to monitor sales trends, forecast demand, and streamline ordering processes. Common types of inventory systems include just-in-time (JIT), ABC analysis, and perpetual inventory systems, each serving different operational needs.
