Meaning
Continuous tracking of stock levels through automated updates ensures that the system shows the actual quantity of goods on hand at any given moment. A system of perpetual inventory records every transaction, from the receipt of raw materials to the shipment of finished products. It governs the real-time visibility of warehouse and production floor assets.
The method ceases to provide value if physical cycle counts are not performed to reconcile digital records with actual stock.
Operational Visibility
Management gains the ability to make informed decisions about procurement and production scheduling based on current data. Implementing perpetual inventory reduces the need for large safety stocks by providing a clearer picture of material availability. This efficiency lowers the cost of holding goods.
Transaction Processing
Scanners and sensors automatically update the database whenever a part moves within the facility. Accurate perpetual inventory relies on the discipline of the workforce to document every movement correctly. Lapses in reporting lead to phantom stock or stockouts.
Cycle Counting
Small batches of items are counted regularly to verify the accuracy of the digital record. Effective perpetual inventory uses these checks to identify and correct discrepancies without shutting down operations for a full physical count. This practice maintains data integrity over time.
