Perpetual Inventory
Perpetual inventory is a method of keeping track of goods and products in real-time. Unlike traditional systems where companies count items periodically, this approach updates stock levels instantly whenever items are bought, sold, or moved. Think of it like a digital checkbook that updates immediately with every transaction. Most modern businesses use special software to maintain perpetual inventory, which helps them know exactly what they have in stock at any moment. This is especially important for retail stores, warehouses, and manufacturing companies that need to manage their products efficiently.
