This accounting method requires a physical count of inventory at specific times, such as at the end of the quarter or fiscal year. This means that a company using this system tracks the inventory on hand at the beginning and end of that specific accounting period. The inventory isn’t tracked on a regular basis or when sales are executed. The periodic inventory system also allows companies to determine the cost of goods sold. The perpetual inventory system is generally more effective than the periodic inventory system.
The perpetual inventory system is expensive because you need different types of technical equipment and trained employees. When I worked at a restaurant in high school, key items were counted every single night. The scanner communicated with a computer in the office, where the accountants reconciled the count with their spreadsheets and worked on the balance sheet for the quarter.
When goods are purchased, they are accounted for in a purchases account, which shows the sum of all purchases during the period. The term inventory refers to the raw materials or finished goods that companies have on hand and available for sale. Inventory is commonly held by a business during the normal course of business. It is among the most valuable assets that a company has because it is one of the primary sources of revenue. Which is used in a perpetual inventory system depending on business policies and preferences.
Disadvantages of periodic inventory system:
Perpetual systems also keep accurate records about the cost of goods sold (COGS) and purchases. However, there are also some disadvantages to using a periodic inventory system. This is because inventory counts are only taken at specific intervals, so there is a greater chance of errors occurring. This is because inventory levels are not tracked continuously, so it can be difficult to identify trends and patterns in inventory usage.
Adjusting and Closing Entries for a Perpetual Inventory System
Shrinkage is a term used when inventory or other assets disappear without an identifiable reason, such as theft. A periodic inventory system is a simplified system for calculating the value of an ending inventory. It only updates the ending inventory balance in the general ledger when a physical inventory count is conducted. Since physical inventory counts are consistency meaning time-consuming, few companies do them more than once a quarter or year. In the meantime, the inventory account in the accounting system continues to show the cost of the inventory that was recorded as of the last physical inventory count. This means that the inventory valuation in the accounting records will be inaccurate, except when a physical count is performed.
- EOQ is a formula that managers use to decide when to purchase inventory based on the cost to hold inventory as well as the firm’s cost to order inventory.
- The ability to estimate COGS continuously also provides a company using a perpetual inventory system the ability to estimate gross profit continuously.
- The main advantage of a perpetual inventory system is that it provides real-time visibility into inventory levels, allowing businesses to make more informed decisions about inventory management.
- Periodic inventory is normally used by small companies that don’t necessarily have the manpower to conduct regular inventory counts.
- The primary difference between periodic and perpetual inventory systems is the way in which inventory levels are tracked and updated.

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. The advantage of a perpetual system in providing a rolling estimate of COGS is clear. A company knows, after each transaction, how much it costs to produce products sold at that point.
Key Differences
The biggest disadvantages of using the perpetual inventory systems arise from the resource constraints for cost and time. This may prohibit smaller or less established companies from investing in the required technologies. The time commitment to train and retrain staff to update inventory is considerable. In addition, since there are fewer physical counts of inventory, the figures recorded in the system may be drastically different from inventory levels in the actual warehouse. A company may not how to use xero accounting for free have correct inventory stock and could make financial decisions based on incorrect data. A physical inventory count requires companies to do a manual “stock-check” of inventory to make sure what they have recorded on the books matches what they physically have in stock.
Because with the advent of cloud computing and manufacturing SaaS providers, this changed radically. Modern manufacturing software with integrated inventory management modules is affordable even to the smaller players. And even though implementing one does require a united effort, it is nowhere near as time and resource-consuming as it was ten years ago.
