The difference between the periodic and perpetual inventory systems

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.

Shrinkage is a termused when inventory or other assets disappear without anidentifiable reason, such as theft. For a perpetual inventorysystem, the adjusting entry to show this difference follows. Thisexample assumes that the merchandise inventory is overstated in theaccounting records and needs to be adjusted downward to reflect theactual value on hand. There are some key differences between perpetual and periodicinventory systems.

The perpetual inventory system gives real-time updates and keeps a constant flow of inventory information available for decision-makers. With advancements in point-of-sale technologies, inventory is updated automatically and transferred into the company’s accounting system. This allows managers to make decisions as it relates to inventory purchases, stocking, and sales. The information can be more robust, with exact purchase costs, sales prices, and dates known. Although a periodic physical count of inventory is still required, a perpetual inventory system may reduce the number of times physical counts are needed. While both the periodic and perpetual inventory systems requirea physical count of inventory, periodic inventorying requires morephysical counts to be conducted.

It makes sense when we look at the formula, the beginning balance plus new purchase less ending must result as the sold item. This formula only uses to make assumptions and calculate the quantity of inventory being sold. To calculate the valuation of goods sold, it will be a problem when the cost we spend changes over time. We will use the valuation methods such as FIFO, LIFO, and Weighted average. Businesses that account for inventory periodically likely use the FIFO method to sell older units first.

Advantages and Disadvantages of the Perpetual Inventory

1If the net method is applied by Rider Inc. the initial purchase entry is recorded as $245. Because these costs result from the acquisition of an asset that eventually becomes an expense when sold, they follow the same debit and credit rules as those accounts. Disadvantages could include fewer inventory counts with opportunity for mismanagement of inventory. https://www.kelleysbookkeeping.com/is-an-invoice-the-same-as-a-bill/ If inventory is central to your business, it must be managed, and to do that it, must be measured. It also wouldn’t make sense for small businesses that sell their inventory as a side project to use perpetual inventory. An appliance repair company selling two or three used refrigerators per month has no need to invest in an expensive point-of-sale system.

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.

1. When a sales return occurs, perpetual inventory systems require recognition of the inventory’s condition.
2. However, the need for frequent physical counts of inventory can suspend business operations each time this is done.
3. Note that for a periodic inventory system, the end of the period adjustments require an update to COGS.
4. Having more accurate tracking of inventory levels also provides a better way of monitoring problems such as theft.

If you don’t need that sort of timeliness and can take the time each month to count inventory, go with periodic. Cost of goods sold is calculated using the FIFO method, and inventory is decreased by that amount. The 10 units from June 1 and four of the June 5 units are included ((10 x $10) + (4 x $10.12)). Keep a budget of expected gross margin each period to compare with the actual margin. Shrinkage will automatically be included in the cost of goods sold, so if the numbers vary by a large amount, it’s time to investigate. Purchases during the quarter amounted to $18,000, and at the end of the quarter, inventory was counted at $42,000.

Sales Discounts, Sales Returns and Allowances, and Cost of GoodsSold will close with the temporary debit balance accounts to IncomeSummary. Sales Discounts, Sales Returns and Allowances, and Cost of Goods Sold will close with the temporary debit balance capital budgeting accounts to Income Summary. Visual inspection can alert the employees as to the quantity of inventory on hand. Perpetual inventory is the system in which company keeps track of each inventory item level since it was purchase and sold to the customer.

Perpetual Inventory

Table6.1 There are severaldifferences in account recognition between the perpetual andperiodic inventory systems. Here, we’ll briefly discussthese additional closing entries and adjustments as they relate tothe perpetual inventory system. However, the need for frequent physical counts of inventory can suspend business operations each time this is done. There are more chances for shrinkage, damaged, or obsolete merchandise because inventory is not constantly monitored.

Since there is no constant monitoring, it may be more difficult to make in-the-moment business decisions about inventory needs. Regardless of the system, Rider holds one piece of inventory with a cost of $260. The decision as to whether to utilize a perpetual or periodic system is based on the added cost of the perpetual system and the difference in the information generated for use by company officials. The company’s inventory is not physically affected by the method selected. Its journal entries for the acquisition of the Model XY-7 bicycle are as follows. The overall cost of the inventory item is not readily available and the quantity (except by visual inspection) is unknown.

Advantages and Disadvantages of the Periodic Inventory

Sales will closewith the temporary credit balance accounts to Income Summary. This list makes it clear that the perpetual inventory system is vastly superior to the periodic inventory system. When new inventory is purchased, it goes directly into the inventory account, and there is no closing entry. Cost of goods sold is increased, and inventory is decreased the instant that inventory is sold. Using proper internal controls, for each purchase, an employee will enter a purchase order into the accounting software that is then approved by a manager. When the inventory is received, along with the invoice from the vendor, payment is approved, and the cash and inventory accounts are updated accordingly.

Perpetual Inventory System

One advantage of the periodic inventory system is that counting inventory allows you to identify shrinkage (inventory that is lost, stolen, or damaged). Inventory that is only managed on the cloud can more easily disappear and end up being sold out of the back of a truck somewhere. As a child, one of my favorite days of the year was when I would go to work with my dad on a Saturday to count inventory. He managed a box plant, and the massive rolls of paper that would later become boxes needed to be counted for that period’s inventory accounting.
