Despite their inherent inaccuracy, periodic inventory systems can be useful in situations where the inventory value is low and a company does not have much of it. In these situations, a simple manual scan of the inventory may be sufficient to verify whether there is any inventory on hand.

A perpetual inventory system is a computerized system that continuously records inventory changes in real-time, thereby reducing or eliminating the need for physical inventory checks. Relying on data provided by electronic point-of-sale technology, it provides a highly detailed view of changes in business drivers inventory and immediate reporting on the amount of inventory in stock.

Proponents of perpetual inventory systems don’t always go out of their way to point out the downsides of these systems, the chief of which is the lack of accounting for loss, breakage, or theft. Perpetual inventory systems track sales constantly and immediately with computerized point-of-sale technology. Periodic inventory systems only track sales when a physical count is ordered and require a point-in-time count. Because perpetual inventory systems lack the ability to account for loss, breakage, or theft, a periodic (physical) inventory can still be necessary. System software provides real-time updates to inventory through the use of barcode scanners or other computerized records of product acquisition, sales, and returns as they occur. A perpetual inventory does not need to be adjusted manually by the company’s accountants, except to the extent that it deviates from the physical inventory count due to loss, breakage, or theft.
