Since inventory counts happen at the end of an accounting period, you must rely on estimates to understand COGS during intervals. When ending inventory is determined, you use it to adjust estimates to reflect actual counts. Out of the two methods, a periodic inventory system is the simpler option, requiring less time, costs, and resources to implement.
The net method allows you to track discounts lost, which then gives you a direct read on how much profit you are losing to what is essentially a finance charge. Before we dive into the COGS details for the periodic system, begin to familiarize yourself with this chart. This is a quick way to compare the differences between how the two methods record the details involved with inventory.
- The cost of goods sold, inventory, and gross margin shown in Figure 10.7 were determined from the previously-stated data, particular to FIFO costing.
- A periodic inventory system is a method of inventory valuation where a physical count of items is conducted at specific intervals, such as the end of the year or accounting period.
- Since the specific identification method, identifies exactly which cost the purchase comes from it does not change under perpetual or periodic.
- It also isn’t as updated as a perpetual system, as it is done at periodic intervals rather than continuously.
- As an accounting method, periodic inventory takes inventory at the beginning of a period, adds new inventory purchases during the period, and deducts ending inventory to derive the cost of goods sold (COGS).
The basic difference between a return and an allowance is that we usually don’t return the goods if they are damaged or unsatisfactory in some way. The vendor issues a Credit Memo anyway and we remove the items from inventory and dispose of them. In the accounting department, you have matched up the receiving documents sent with this invoice and it is now ready to be paid.
Inventory Write-Down: Strategies and Factors to Consider
Note that for a periodic inventory system, the end of the period adjustments require an update to COGS. To determine the value of Cost of Goods Sold, the business will have to look at the beginning inventory balance, purchases, purchase returns and allowances, discounts, and the ending inventory balance. Since businesses often carry products in the thousands, performing a physical count can be difficult and time-consuming. Imagine owning an office supply store and trying to count and record every ballpoint pen in stock. This is why many companies perform a physical count only once a quarter or even once a year.
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. In a periodic inventory system, you use regularly scheduled physical inventory counts to measure the cost of goods sold and see how much product you have available.

Periodic inventory can be too simplistic, especially for businesses experiencing growth or expanding to new locations. Business owners subtract the cost of goods sold from total revenue to get their gross profit, which is a measurement of the business’s profitability. We hope our guide was helpful in understanding the basics of the periodic inventory system. Because there’s no constant inventory tracking, it can be difficult for a firm to be aware of which goods are running low on stock, or if there’s an excess supply for a type of inventory.
In contrast to highly complex processes, the periodic inventory system is easy to implement and costs significantly less. So there’s no longer a need for businesses to manually count their merchandise, or write down journal entries by hand. The periodic inventory approach is primarily used by small businesses that deal with very few transactions, or companies that only have a limited number of inventory. That’s why businesses with high sales volume and multiple sales channels use a perpetual inventory system, instead. 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.
Paying for Inventory Purchased on Credit
There are some key differences between perpetual and periodic inventory systems. When a company uses the perpetual inventory system and makes a purchase, they will automatically update the Merchandise Inventory account. https://www.wave-accounting.net/, Purchases will be updated, while Merchandise Inventory will remain unchanged until the company counts and verifies its inventory balance.
A perpetual inventory system is a method that records each sale or purchase of inventory in real-time, through automated software. The perpetual system may be better suited for businesses that have larger, more complex levels of inventory and those with higher sales volumes. For instance, grocery stores or pharmacies tend to use perpetual inventory systems. One of the main differences between these two types of inventory systems involves the companies that use them. Smaller businesses and those with low sales volumes may be better off using the periodic system. In these cases, inventories are small enough that they are easy to manage using manual counts.
To illustrate the periodic inventory method journal entries, assume that Hanlon Food Store made two purchases of merchandise from Smith Company. While each inventory system has its own advantages and disadvantages, the more popular system is the perpetual inventory system. The ability to have real-time data to make decisions, the constant update to inventory, and the integration to point-of-sale systems, outweigh the cost and time investments needed to maintain the system. You take the beginning inventory costs for a period, add the cost of inventory purchases during the interval and subtract the cost of your remaining inventory after you’ve gathered your ending count. Doing a physical count of all your on-hand inventory items increases the likelihood of human error.
Practice Question: Purchases Under a Periodic System
When a buyer receives a reduction in the price of goods shipped but does not return the merchandise, a purchase allowance results. Inventory management systems affect every aspect of operations, from warehouse and overhead costs to order fulfillment and generating revenue. Inventory shrinkage refers to the difference between how many items should be remaining (based on sales) and how many actually are. These discrepancies can happen as a result of employee theft, shoplifting, or vendor mistakes. Each of these methods can be used to help you calculate the value of your beginning inventory and ending inventory.
Its counterpart, last-in, first-out (LIFO), assumes the opposite and calculates ending inventory using the first items purchased. At the end of every period, the purchases account total is added to the beginning inventory. By spending less time on inventory tracking, businesses can focus on other growth areas such as sales, marketing, vertical analysis definition and customer service. However, more advanced inventory management systems can add costs and complexity to your operations. For small businesses and entrepreneurs, it’s important to know when to choose simplicity over the latest tech. When a business sells merchandise, only one journal entry is made to recognize the sale.

Both are accounting methods that businesses use to track the number of products they have available. Periodic inventory is one that involves a physical count at various periods of time while perpetual inventory is computerized, using point-of-sale and enterprise asset management systems. The former is more cost-efficient while the latter takes more time and money to execute. On the other hand, perpetual inventory systems utilize accounting software to keep track of inventory in real-time. A barcode scanner or point-of-sale system records whenever an item is purchased, sold, or returned.
There is not a corresponding and immediate decline in the inventory balance at the same time, because the periodic inventory system only adjusts the inventory balance at the end of the accounting period. Thus, there is not a direct linkage between sales and inventory in a periodic inventory system. A sales allowance and sales discount follow the same recording formats for either perpetual or periodic inventory systems. A perpetual inventory system automatically updates and records the inventory account every time a sale, or purchase of inventory, occurs.
