For when a periodic inventory system is used instance, it may not provide real-time visibility into inventory levels, leading to potential stock-outs or overstocking situations. This additionally means that the COGS figure may not be as precise as in a perpetual inventory system which constantly updates inventory levels. As a result, the periodic inventory system may require additional internal controls to minimise errors and discrepancies during the physical counting process. Each business should carefully evaluate its needs and requirements to determine the most suitable inventory management approach. On the other hand, perpetual inventory systems utilize accounting software to keep track of inventory in real-time.

Of course, some of that inventory can become” Finished Goods” and be sold during the period, but your accountant doesn’t need to worry about that. 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. A periodic Inventory System is defined as an inventory valuation method in which inventories are physically counted at the end of a specific period to determine the cost of goods sold. That means ending inventory balance is updated only at the end of the period instead of a perpetual inventory system where inventories are counted frequently.
- With the perpetual inventory method, the weighted average cost is recalculated after each new purchase order.

Advantages of the periodic inventory system
Periodic inventory allows a business to track its beginning inventory and ending inventory within an accounting period for their financial statements. Even if you have simple stock and it’s likely to stay that way, modern inventory software has matured a lot in the past years. Many providers offer easy-to-use, fully cloud-based solutions that significantly enhance your inventory management and tracking at very affordable prices. Implementing an automated inventory management system is much easier when the company is still relatively small, reducing the need for complex change management later. Periodic inventory systems are still widely used today, usually by smaller companies with limited inventories and low trade volumes. They are often used within spreadsheets, simple standalone inventory software, or paper-based inventory management systems.

Workflow and productivity can be affected by this disruption, particularly in companies with high inventory turnover rates or those engaged in seasonal demand changes. Order fulfillment delays, potential customer dissatisfaction, and revenue loss can result from operational disturbance. This list makes it clear that the perpetual inventory system is vastly superior to the periodic inventory system.
