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 understanding deferred revenue vs accrued expense may not have correct inventory stock and could make financial decisions based on incorrect data.

Point-of-Sale Systems

An effective inventory system can reduce the bullwhip effect, where small fluctuations in demand at the retail level cause progressively larger fluctuations up the supply chain. By providing accurate, real-time data, a perpetual inventory system can help companies respond more quickly to changes in demand, thereby minimizing this phenomenon. Small- and medium-sized companies or companies with small physical inventories continue to use the periodic inventory system, though many are opting for low-cost perpetual inventory systems. The differences between perpetual and periodic inventory systems go beyond how the two systems function, although that is the main point of distinction.

  4. A perpetual inventory system uses point-of-sale terminals, scanners, and software to record all transactions in real time and maintain an estimate of inventory on a continuous basis.
  5. The perpetual inventory system is an accurate system that does not rely on manual and physical inventory count very often.

Perpetual Vs. Periodic Inventory System – Key Differences

At the end of the period, a perpetual inventory system will have the Merchandise Inventory account up-to-date; the only thing left to do is to compare a physical count of inventory to what is on the books. 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. Differences could occur due to mismanagement, shrinkage, damage, or outdated merchandise. Shrinkage is a term used when inventory or other assets disappear without an identifiable reason, such as theft. For a perpetual inventory system, the adjusting entry to show this difference follows. This example assumes that the merchandise inventory is overstated in the accounting records and needs to be adjusted downward to reflect the actual value on hand.

What Is Perpetual Inventory?

But this can change as companies grow, which means they may end up using the perpetual inventory system when their labor pool expands. Periodic inventory is normally used by small companies that don’t necessarily have the manpower to conduct regular inventory counts. These companies often don’t need accounting software to do the counts, which means inventory is counted by hand. As such, the system is commonly used by companies that sell small quantities of inventory, including art and auto dealers. On the other hand, the periodic system uses the manual and physical inventory count.

2 Compare and Contrast Perpetual versus Periodic Inventory Systems

Let’s first go over the periodic method journal entries then segue into the perpetual inventory system afterward. In our illustration, let’s use sample data from a fictitious company called FitTees. Note that for a periodic inventory system, the end of the periodadjustments require an update to COGS.

There are two ways in which a company may account for their inventory. Let us consider some key areas in inventory management concerning perpetual and periodic systems. Under the perpetual system, managers are able to make the appropriate timing of purchases with a clear knowledge of the number of goods on hand at various locations. Having more accurate tracking of inventory levels also provides a better way of monitoring problems such as theft.

When to Use a Perpetual Inventory System

Since the inventory account is updated with each transaction, the automation tools become a prerequisite for this system. For all other businesses, we recommend using inventory management software to implement a perpetual inventory management system. It can be cumbersome and time-consuming, as it requires you to manually count and record your inventory. And because this is a physical count, there is a higher chance of error. It also isn’t as up to date as a perpetual system, as it is done at periodic intervals rather than continuously.

A periodic system is cheaper to operate because no attempt is made to monitor inventory balances (in total or individually) until financial statements are to be prepared. A periodic system does allow a company to control costs by keeping track of the individual inventory costs as they are incurred. The biggest disadvantages of using the perpetual inventorysystems arise from the resource constraints for cost and time. Thismay prohibit smaller or less established companies from investingin the required technologies. The time commitment to train andretrain staff to update inventory is considerable.

Even if you’re a small business, that doesn’t mean that the perpetual inventory system isn’t beneficial to you. In choosing an inventory system, you have to weigh the costs and benefits. As long as the benefits exceed the cost, you can use any of the two inventory systems. In the following section, we’ll illustrate the difference between the periodic inventory system and perpetual inventory system by showing the journal entries while using the FIFO cost flow assumption.

Some companies don’t wait until the end of an accounting period to track inventory. Inventory is tracked instantaneously when purchased or when sales are made. Here, we’ll briefly discuss these additional closing entries and adjustments as they relate to the perpetual inventory system. A sales allowance and sales discount follow the same recording formats for either perpetual or periodic inventory systems.
