Conducting a physical inventory of goods/products on a scheduled basis Show
What is the Periodic Inventory System?The periodic inventory system refers to conducting a physical inventory count of goods/products on a scheduled basis. Maintaining physical inventories can be costly because the process eats up time and manpower. Thus, many companies only conduct physical inventory counts periodically. A periodic inventory system is a commonly used alternative to a perpetual inventory system. How a Periodic Inventory System WorksBecause the physical accounting for all goods and products in stock is so time-consuming, most companies conduct them intermittently, which often means once a year, or maybe up to three or four times per year. In a periodic system, all transactions conducted are listed in a purchase account for the company, which monitors inventory based on deduction of the cost of goods sold (COGS). It doesn’t, however, account for broken, damaged, or lost goods and also doesn’t typically reflect returned items. It is why physical inventories are necessary, to accurately reflect how many tangible goods are in a store or storage area. After a periodic inventory count, the purchase account records are changed to reflect the accurate monetary accounting of goods based on the number of goods that are physically present. Calculations in the Periodic Inventory SystemAs discussed above, calculating the value of an inventory between one physical inventory count to the next, is done by starting with opening balances and adjusting for any accounting additions or subtractions to the account. The calculation is fairly simple: Starting inventory (based on the last physical inventory) plus the total number of purchases made within the period between the previous physical inventory and the next physical inventory is equal to the total amount of the goods that are available to be sold. The total inventory value is the cost (or total price) of goods that are able to be sold – minus the total number of goods sold between physical inventories. The physical inventory count is then completed, and compared to the value calculated. Any differences are then expensed to the cost of goods sold account. The periodic inventory system is an integral part of a company’s operations and is the most common type of inventory process followed because, again, physical inventories involve substantial amounts of time which, ultimately, cost money. While discrepancies are more likely to occur the more time passes between inventories, maintaining at least periodic updates to a company’s goods available for sale typically prevents any major issues in terms of lost goods or lost opportunities for profit.

Connect With a Fulfillment Expert Today.Get Started There are many inventory valuation methods available for businesses to use, and picking the right valuation method can have long-lasting effects. One of the more common and simplistic valuation methods is a periodic inventory system. Periodic inventory systems are commonly used by startups and small businesses, and you might be wondering if it’s the right method for you. In this article, we’ll take a look at what periodic inventory is, how to implement it, and how it can benefit your business. What is periodic inventory?Periodic inventory is a system of inventory valuation where the business’s inventory and cost of goods sold (COGS) are not updated in the accounting records after each sale and/or inventory purchase. Instead, the income statement is updated after a designated accounting period has passed. How does periodic inventory work?In a periodic system, businesses don’t keep a continuous record of each sale or purchase; inventory balance updates are only recorded in a purchases account over a specified period of time (e.g., each month, quarter, or year). At the end of the accounting period, the final inventory balance and COGS is determined through a physical inventory count. What is the difference between the periodic inventory and perpetual inventory systems?A periodic inventory system measures the level of inventory and cost of goods sold through occasional physical counts. In contrast, the perpetual inventory system is a method that continuously monitors a business’s inventory balance by automatically updating inventory records after each sale or purchase. The periodic inventory system is ideal for smaller inventories and order volumes, whereas fast-growing or midsize to large businesses usually resort to a perpetual system for more accurate and real-time records. How do you calculate periodic inventory?It’s straightforward to calculate the cost of goods sold using the periodic inventory system. First, we’ll walk through the elements needed and then an example.
Periodic inventory formulaAs periodic inventory is an accounting method rather than a calculation itself, there is no formula. However, we will use the formulas for calculating cost of goods sold and cost of goods available. To calculate the cost of goods available, add the account total for purchases to the inventory’s initial balance.
Then, at the end of an accounting period, take a physical count of each item. This will be your ending inventory balance. Finally, subtract the ending inventory balance (or closing inventory) from the cost of goods available to determine the COGS.
A periodic inventory exampleNow we’ll take a look at how you’d practically apply periodic inventory to your business. Let’s say you run an ecommerce store and:
As mentioned, we need to calculate the cost of goods sold using this formula:
Plugging the values in, we get:
Using the periodic inventory method, the total cost of goods sold for the period comes to $350,000. What are the advantages of using a periodic inventory system?Periodic inventory allows a business to track its beginning inventory and ending inventory within an accounting period for their financial statements. Here are some of the ways it can benefit your business. 1. Easy to implementPeriodic inventory systems are relatively simple to implement as it requires fewer records than other valuation methods. The calculations are easy too. 2. Great option for small businessA periodic inventory system is best suited for smaller businesses that don’t keep too much stock in their inventory. For such businesses, it’s easy to perform a physical inventory count. It’s also far simpler to estimate the cost of goods sold over designated periods of time. That means companies with a high inventory turnover rate, large SKU count, multichannel inventory management needs, or that need real-time data are better suited for alternative methods. 3. Requires minimal informationWhile a perpetual system requires comprehensive information about each sale and purchase, periodic systems don’t need to monitor each transaction. Periodic inventory systems are very simple in the world of ecommerce bookkeeping and can compute the cost of goods sold and available for small inventories using a few data points. What are the drawbacks of using a periodic inventory system?The periodic inventory system can be risky for many businesses as stock levels are not up to date, leading to delays in issues being identified, inventory write-offs, and major challenges with inventory forecasting as you don’t always have exact figures on finished goods inventory, or the total stock available for customers to purchase. Periodic inventory can also be more prone to human error as it relies on physical inventory audits rather than a more automated system that’s tracked digitally. By the time a physical count is completed, there may be inventory reconciliations needed to address stock discrepancies. Recordkeeping in a periodic inventory system may also become more time-consuming as your business grows and you add more inventory items. You might want to consider ecommerce accounting software and automated methods, such as the perpetual inventory system, if your business is growing fast.

Periodic inventory FAQsHere are some common questions that business owners have about periodic inventory systems with answers to give you some guidance. What is a periodic inventory system? A periodic inventory system is a method of inventory valuation where the account is periodically updated. In other words, the factor that determines changes to recorded inventory balance is not triggered by each new order but rather an overall time period. How are periodic and perpetual inventory systems different?A periodic inventory system measures the inventory levels periodically through physical counts. The perpetual method continuously updates inventory records after each sale or purchase, monitoring the inventory balance. Small business owners with less inventory benefit more from periodic systems than larger merchants. How to do periodic inventory systems
To implement a periodic inventory accounting system, all you need is a team to perform the physical inventory count and an accounting method for determining the cost of closing inventory. The LIFO (last-in first-out), FIFO (first-in first-out), and the inventory weighted average methods are all promising calculation techniques. How to record periodic inventory systemsFor the periodic inventory method, there’s no need to continually record the inventory levels. Only the beginning and ending balances are needed, often completed by a physical count to calculate inventory value. Because updates are so infrequent in a periodic inventory system, no effort is made to keep real-time records of customer sales, inventory purchases, and the cost of goods sold. What is the meaning of periodic system?A periodic inventory system is a mechanism for measuring the level of inventory and the cost of goods sold (COGS) by using an occasional physical count. Periodic systems use regular and random inventory audits to update inventory-tracking information.
How do you know if it is periodic or perpetual?The key difference between periodic and perpetual accounting is timing. Periodic inventory is done at the end of a period to create financial statements. Perpetual inventory is done as sales and inventory purchases happen.
What is periodic and perpetual accounting?Key Takeaways. The periodic inventory system uses an occasional physical count to measure the level of inventory and the cost of goods sold. The perpetual system keeps track of inventory balances continuously, with updates made automatically whenever a product is received or sold.
