Periodic inventory system: what it is + how to calculate

One of the main disadvantages is that they do not provide real-time updates on inventory levels, which can lead to stockouts or overstocking. A periodic inventory system is a method of inventory control that involves tracking inventory levels at specific intervals rather than continuously. A periodic inventory system—which involves updating inventory records at scheduled intervals rather than in real time—could save you time, money, and headaches. Overall, this system is favored by businesses that don’t require instant stock updates and can manage with periodic counts to keep things simple and cost-effective. So, instead of knowing inventory levels in real-time, businesses using the periodic system only get updates when they perform those counts. It’s a straightforward way to manage inventory, but it also means stock numbers are only accurate right after the count is completed.

Best Practices for Accuracy and Efficiency
A Perpetual Inventory System tracks inventory in real-time, updating stock levels automatically whenever a sale or purchase occurs. This system relies on barcode scanners, RFID technology, and inventory management software to ensure accuracy. A POS system tracks your sales, providing insight into inventory usage between counts. Even though a periodic inventory system doesn’t update stock in real time, POS systems clearly show which products are selling quickly. Deciding between periodic and perpetual inventory tracking depends on how often your stock moves and how much control you need.

Instead, a “purchase account” will be created in a periodic system for each bought inventory, which is an ‘asset.’ All the inventory purchases are stored in this account.
