Implementing a perpetual system earlier in the company’s inception enables staff to have a long-term record of the inventory and also keeps the business from growing out of a periodic system one day. A perpetual system can scale, so whether you have five products (today) or 200 products (tomorrow), a perpetual system can effectively manage inventory control. If your company has been progressively growing and regular inventory counts are becoming complex, you can use the perpetual inventory system to simplify inventory management. Because the perpetual inventory system does not allow for regular physical inventory counting, inventory levels may differ from real inventory in the warehouse. Using the average cost formula, beginning inventory and purchases are simply summed to calculate the weighted average unit cost.
- In the periodic inventory system, you start by recording your beginning inventory.
- The company then applies first-in, first-out (FIFO) method to compute the cost of ending inventory.
- For instance, an automobile showroom business will not need to conduct a physical count of vehicles regularly.
- As a result, the remaining stock is the inventory from the most recent acquisitions.
- To understand how the accounts might look in the periodic inventory approach, look at the table below.
A trading company has provided the following data about purchases and sales of a commodity made during the year 2016. The periodic inventory system is not inclined towards technology and automation. Most businesses do not use sophisticated technology for automation with this system. The cost of goods sold (COGS) is then calculated by using the figures of beginning inventory, adding new purchases, and deducting the ending inventory figures.
When to Use Periodic Inventory System
The periodic inventory system is becoming an old-fashioned method of tracking inventory, and for a good reason. The growing use of cloud accounting software has made inventory tracking incredibly easy and cheap to implement. As stock levels arise, and your company grows, the periodic inventory system becomes complex and difficult to manage. That’s why the approach isn’t suitable for every type of company, and the majority of businesses use perpetual inventory instead. More specifically, under a periodic inventory, the physical count of inventory and calculation of the inventory costs is done periodically, at regularly occurring intervals. A perpetual system is superior to a periodic system in many ways, especially for companies that are considering their longevity.
A periodic inventory system requires less bookkeeping, as there is no need to have separate accounting for raw materials, work in progress, and finished inventory. Then, you subtract the previously counted ending inventory from the total cost of goods available for sale, to compute the costs of goods sold. Merchandising businesses that deal with hundreds of transactions a day, such as grocery stores or pharmacies, can’t possibly maintain their inventory through a periodic inventory system. That’s why a periodic inventory system is only mainly used by small businesses with limited inventory and few financial transactions.

At a grocery store using the perpetual inventory system, when products with barcodes are swiped and paid for, the system automatically updates inventory levels in a database. Since the periodic inventory does not regularly update the main inventory account, it does not require subsets. However, a company may divide the main inventory account into a different subset of work in progress, beginning and ending inventories. The perpetual system can also help streamline different accounting tasks, like updating your general ledger, managing accounts receivable, and giving you a more accurate inventory valuation. You do a physical inventory count at the end of the period and compare it to the beginning inventory to determine the cost of goods sold (COGS). Under first-in, first-out (FIFO) method, the costs are chronologically charged to cost of goods sold (COGS) i.e., the first costs incurred are first costs charged to cost of goods sold (COGS).

In contrast, the perpetual inventory system gives you real-time inventory counts because it updates each time a unit moves in or out of your inventory. Under the periodic inventory system, all purchases made between physical inventory counts are recorded in a purchases account. When a physical inventory count is done, the balance in the purchases account is then shifted into the inventory account, which in turn is adjusted to match the cost of the ending inventory. Between the two accounting systems, there are differences in how you update the accounts and which accounts you need. In a perpetual system, the software is continuously updating the general ledger when there are changes to the inventory.
