Companies that don’t meet those criteria now but anticipate growth in the future may want to consider such a system as well. Thus we are left with a sales figure of $1,500 that can be matched against an expense – cost of goods sold – of $1,000, to give us $500 gross profit. A periodic inventory system does not account for individual or unit counts for inventory, such as raw material or work in progress accounts.

On February 28, 2009, Best Buy reported inventory totaling $4.753 billion. However, the company also needs specific information as to the quantity, type, and location of all televisions, cameras, computers, and the like that make up this sum. That is the significance of a perpetual system; it provides the ability to keep track of the various purchase order number vs purchase order item number types of merchandise. The nature and type of business you have will factor into the kind of inventory you use. It may make sense to use the periodic system if you have a small business with an easy-to-manage inventory. If you have a larger company with more complex inventory levels, you may want to consider implementing a perpetual system.

Any discrepancies or shortages of inventory due to theft can be adjusted with the following accounting entry. The perpetual inventory system is the process of keeping inventory records in real-time. The company updates its inventory account as and when it makes new inventory purchases. But a company using a periodic inventory system will not know the amount for its accounting records until the physical count is completed. In perpetual inventory, inventory is updated per sale, and the COGS account is too. In periodic inventory, the COGS account entry is done as a lump sum adjustment and isn’t created until inventory is counted.
The Ins and Outs of Perpetual Inventory
A periodic system does allow a company to control costs by keeping track of the individual inventory costs as they are incurred. A purchase return or allowance under perpetual inventory systems
updates Merchandise Inventory for any decreased cost. Under
periodic inventory systems, a temporary account, Purchase Returns
and Allowances, is updated. Purchase Returns and Allowances is a
contra account and is used to reduce Purchases. There are several ways that companies can account for their inventory.
Periodic vs Perpetual Inventory System
Under periodic inventory systems, only the sales return is recognized, but not the inventory condition entry. A periodic inventory system updates and records the inventory account at certain, scheduled times at the end of an operating cycle. The update and recognition could occur at the end of the month, quarter, and year.
Definition of Periodic Inventory System
Inventory shrinkage happens when there is a discrepancy between the actual stock and the inventory list. Shrinkage isn’t necessarily evident in the periodic inventory system. That’s because it takes the inventory at the beginning of the reporting period and at the end unlike the perpetual system, which takes regular inventory counts. So if there is any theft, damage, or unknown causes of loss, it isn’t automatically evident.

There is a gap between the sale or purchase of inventory and when the inventory activity is recognized. A periodic inventory system updates and records the inventory account at certain, scheduled times at the end of an operating cycle. A perpetual inventory system automatically updates and records the inventory account every time a sale, or purchase of inventory, occurs. You can consider this “recording as you go.” The recognition of each sale or purchase happens immediately upon sale or purchase.
When you use perpetual inventory, the POS system automatically makes changes to your inventory levels. You can access your inventory reports online anytime, making it easier to manage or purchase inventory. Contrarily, the periodic system relies on the physical count of inventory. Hence, the chances of errors with inventory count are smaller in this system. On the other hand, the periodic system uses the manual and physical inventory count. Disadvantages could include fewer inventory counts with opportunity for mismanagement of inventory.
