Just-in-Time Inventory (JIT) Inventory is an approach to inventory management that seeks to reduce the amount of inventory held by a business by only ordering and receiving goods when they are needed. This system is designed to reduce the costs associated with storing and managing inventory, as well as to improve the efficiency of the supply chain. JIT inventory is based on the principle of ordering and receiving goods only when they are needed, rather than stocking up on inventory and holding high quantities. This system requires close coordination between suppliers and customers, as well as accurate forecasting of demand. JIT inventory is often used in combination with other inventory management systems, such as Kanban, to ensure that the right amount of inventory is available when needed.
