Perpetual Inventory System: Definition & Examples for Business

At all other times, the inventory records under a periodic inventory system will not reflect the amount of inventory that is actually on hand. 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. Clearly, periodic inventory systems are used by quite small businesses that operate with relatively primitive paper-based systems. Organizations with larger inventory counts or more valuable inventory, and especially those with sophisticated materials management systems, will need to use a perpetual inventory system. Unlike periodic inventory systems, which update inventory counts at specific intervals, perpetual systems provide a constant, up-to-date view of inventory, including sales, purchases, and adjustments.

It is far more sophisticated than the periodic system of inventory management. Huge businesses have difficulty performing the cycle counts that are necessary for a periodic system.

Can Perpetual Inventory be integrated with other business software?

A perpetual inventory system differs from a periodic inventory system, a method in which a company maintains records of its inventory by regularly scheduled physical counts.

This high level of accuracy is essential in preventing stockouts or overstocking, which can lead to lost sales or unnecessary carrying costs. A perpetual inventory system is a record-keeping accounting system that logs https://www.adprun.net/ each and every sale and purchase automatically, continually maintaining accurate reflections of inventory numbers. This, in essence, prevents companies from having to do physical stock counts each time they need to know how much inventory is left on hand.
