However, like any system, perpetual inventory comes with its set of advantages and disadvantages, each impacting businesses in various ways. A physical inventory count is usually taken once each year, although in some cases it may be done quarterly or even more frequently. Therefore, an actual physical inventory count should be performed at specified intervals, usually once a year. As inventory is sold, the Merchandise Inventory account is credited, and Cost of Goods Sold is debited for the cost of the inventory sold. Similarly, every package that is dispatched is scanned by barcode and loaded onto a vehicle. The journal entries used when bookkeeping in the perpetual inventory system are different compared to the ones used in a periodic system.

Consider a perpetual inventory system that is used in a post office warehouse, which ships and receives packages each day. Rather than asking employees to perform constant record-keeping, firms had more productive tasks for their workers.

What Is the Weighted Average Cost Perpetual Inventory Method?

It means that the COGS is calculated based on the cost of the most recent inventory items, while the ending inventory is based on the cost of the oldest inventory items. Let’s assume that a firm has started its year with a beginning inventory of pens costing $10,000. The process of accounting for perpetual inventories is shown in the following example. This involves computing the cost of goods sold during the period and the appropriate cost of the ending inventory. Large companies or those with complex inventories are well suited to a perpetual system.

The calculations for perpetual inventory are typically done as you go versus waiting until the end of the accounting period, like with periodic inventory. Businesses that use POS systems and sell high-value items (e.g., car dealerships) usually use perpetual inventory systems to frequently count inventory. There are many factors that can affect the accuracy of your business’s inventory levels. You may forget to record a transaction or experience employee theft at your business.

Often, this means employees use barcode scanners to record sales, purchases or returns at the moment they happen. Employees feed this information into a continually adjusted database that tracks each change. The automatic, or perpetual, updating of the inventory is what gives the system its name and differentiates it from the periodic approach. System errors can lead to inaccurate perpetual inventory definition inventory records, which can cause a host of problems, from stockouts and overstock situations to inaccurate financial reporting.

Further, an organisation with several retail locations may find it is easier to control inventory when there’s a regularly updated database of products. Take, for example, a tool retailer that has a customer looking for a specific type of wrench, one that is rarely requested and sold. Using a perpetual system, it has real-time information about which site may have one in stock so the customer can go get his wrench quickly instead of driving from store to store looking for it. Inventory management software and processes allow for real-time updating of the inventory count.

Perpetual vs. periodic inventory

The difference between the methods is the timing of when the inventory cost is recognized, and the cost of inventory sold is posted to the cost of sales expense account. Because perpetual inventory systems lack the ability to account for loss, breakage, or theft, a periodic (physical) inventory can still be necessary. Optimizing inventory management processes is essential for businesses to operate efficiently, reduce costs, and improve customer satisfaction. One method that has gained popularity for its real-time tracking and accurate inventory control is the Perpetual Inventory System.
