The term periodic inventory system refers to a method of inventory valuation for financial reporting purposes in which a physical count of the inventory is performed at specific intervals. 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). It is both easier to implement and cost-effective by companies that use it, which are usually small businesses.
As discussed above, both perpetual and periodic inventory systems have their pros and cons, and selecting between the two is contingent upon your business. Each time a company purchases new inventory, the company first updates the purchases account. Then, a physical count of inventory is required to confirm the inventory update.
In a perpetual system, digital technology is used to update the inventory as each sale occurs. These adjustments are made automatically, so decision-makers and managers always know the level of inventory on hand. Here, we’ll briefly discuss these additional closing entries and adjustments as they relate to the perpetual 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.
- For a perpetual inventory
system, the adjusting entry to show this difference follows.
- With this application, customers have payment flexibility, and businesses can make present decisions to positively affect growth.
- Inventory refers to any raw materials and finished goods that companies have on hand for production purposes or that are sold on the market to consumers.
- As mentioned on their site, they are manufacturers and distributors of FMCG products, based in Kigali, Rwanda.
- The advantages and disadvantages of a perpetual inventory system are outlined below.
This list makes it clear that the perpetual inventory system is vastly superior to the periodic inventory system. The primary case where a periodic system might make sense is when the amount of inventory is very small, and where you can visually review it without any particular need for more detailed inventory records. To determine your business’s profitability, you’ll need to know how much you spent to produce, ship, store, and manage the inventory you’ve sold. Perpetual inventory systems came about in the technological age as computers allowed for tighter tracking of inventory levels.
It encompasses the money invested in producing goods, along with labor and material costs. Thus, it can easily embed other systems such as cyclic accounting methods. Contrarily, the periodic system that does not update records regularly cannot embed support systems easily. The perpetual system is more inclined towards the automation and use of technology to maintain inventory records in real-time. Contrarily, the periodic system considers the physical count of inventory using manual tools for more accuracy. Second, perpetual inventory systems are often more expensive than periodic systems.
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 types of merchandise. 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. This means that perpetual inventory and periodic inventory are counting the same way to arrive at gross margin. Still, the perpetual inventory method is more accurate and more reflective of day-to-day reality.
After researching in great depth, I finally found the case study of Sulfo Rwanda Industries. It’s an excellent example of the practical applications of the perpetual inventory method. In the perpetual inventory system, purchases and returns are also recorded automatically in the inventory count. It’s always about time; time plays a vital role in today’s world you lose time, you lose money. The business owners and warehouse managers soon identified this, and therefore they wanted an inventory management method that helped them make instantaneous changes in their inventory levels. Contrarily, the periodic system relies on the physical count of inventory.
The LIFO method is a great way to show higher COGS expenses and lower net income. One day you get an order for a woolen coat that has been very rarely asked, and it’s a summer season. Once the COGS balance has been established, an adjustment is
made to Merchandise Inventory and COGS, and COGS is closed to
prepare for the next period. Once the COGS balance has been established, an adjustment is made to Merchandise Inventory and COGS, and COGS is closed to prepare for the next period.

What Is Perpetual Inventory?
It also isn’t as updated as a perpetual system, as it is done at periodic intervals rather than continuously. One of the main differences between these two types full disclosure definition 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.
- A periodic inventory system requires counting items at various intervals—i.e., weekly, monthly, quarterly, or annually.
- Thus, it can easily embed other systems such as cyclic accounting methods.
- If the company utilizes a perpetual inventory system, COGS is available on a continuous basis.
- At any point in time, company officials do have access to the amounts spent for each of the individual costs (such as transportation and assembly) for monitoring purposes.
- The choice between perpetual and periodic inventory systems depends on the size, complexity, and nature of your small business.
The perpetual inventory system updates the cost of goods sold and subsequently the inventory account regularly. In a perpetual inventory system, we always update our COGS account with every transaction. Our COGS and Inventory under the perpetual method are determined by the journal entries already made. While the perpetual inventory method provides a close picture of the true inventory information, it is a good idea for companies using a perpetual inventory system to do a physical inventory periodically. Periodic inventory is when information about amount and availability of a product is updated only periodically. Physical inventories are conducted at set time intervals; both cost of goods sold and the inventory are adjusted at the time of the physical inventory.
Understanding Perpetual Inventory 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. Changes in inventory are accurate (as long as there is no theft or damage to any goods) and can be easily accessed immediately.
This makes it ideal for larger operations where multiple locations are being managed. Periodic inventories can be done once a week, monthly, at the end of every quarter, or annually based on the size of the items in stock. This inventory type is usually conducted manually using a physical or computer-based spreadsheet. Cost flow assumptions are used to find out the ending inventory and COGS that will ultimately determine the efficiency of your inventory management techniques and skills. According to waspbarcode’s small business report, there are around 46% of small businesses in the United States that don’t track their inventory or use a manual method.

Comparing Inventory Systems
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.
Adjusting and Closing Entries for a Perpetual Inventory
General Ledger account Inventory is not updated whenever the purchases of goods to be resold are made. For this, a temporary account is considered that begins each year with a zero balance. And the ending balance is removed to another account at the end of the year.
What exactly is the Periodic Inventory Method and How it Works
In our illustration, let’s use sample data from a fictitious company called FitTees. Businesses can choose to use either a perpetual period periodic inventory system to calculate their cost of goods sold (COGS). A periodic inventory system calculates the COGS following a physical inventory count at period-end, whereas a perpetual inventory system calculates the COGS after each sale. A periodic inventory system updates and records
the inventory account at certain, scheduled times at the end of an
