Inventory control methods are used to ensure businesses maintain the right amount of products needed to meet customer demand. There are two main types of inventory control methods: periodic and perpetual. Periodic inventory control methods involve counting all inventory at certain set intervals, such as weekly or monthly, while perpetual inventory control methods involve monitoring and adjusting stock levels in real-time. With proper implementation, these methods can help minimize losses from theft and spoilage, reduce costs associated with overstocking or understocking, and improve efficiency and accuracy when it comes to stocking inventories.
