How often is the inventory account updated in a perpetual inventory system?
One of the challenges of the periodic inventory method is making appropriate updates to the general ledger (GL). With a computerized perpetual inventory system, the GL is updated automatically, but the periodic system doesn’t allow that. Show
Rather than debiting Inventory, a company using periodic inventory debits a temporary account called Purchases. Any adjustments related to these purchases of goods will later be credited to a GL contra account such as Purchases Discounts or Purchases Returns and Allowances. When the balances of these three purchases accounts (Purchases, Purchase Discounts, and Purchase Returns and Allowances) are combined, the resulting amount is known as net purchases. When goods are sold under the periodic inventory system, there is no entry to credit the Inventory account or to debit the account Cost of Goods Sold. Hence, the Inventory account contains only the ending balance from the previous year. As a result, the company must compute an inventory amount at the end of each accounting period in order to report the amount of its ending inventory for its balance sheet and the cost of goods sold for its income statement.

Computing the Inventory under the Periodic Inventory MethodAt the end of an accounting year, the company’s ending inventory is normally computed based on a physical count of its inventory items. Inventory amounts for the monthly and quarterly financial statements are usually estimates. Under the periodic inventory system, the cost of goods sold is computed as demonstrated with this example of the Geyer Co.: Geyer Co. The following formula is worth committing to memory: [latex]\text{Beginning inventory}+\text{Purchases}-\text{Ending inventory}=\text{Cost of goods sold}[/latex] Compare the above calculation to one from the same company if it used the perpetual system where all transactions run through only two accounts: Merchandise Inventory and Cost of Goods Sold: Geyer Co.Income Statement (partial) For the year ended December 31, 20XXSales Revenue, net$2,548,959Costs of goods sold1,741,663Gross profitSingle Line$807,296Double LineGross profit %31.67% Companies using the periodic inventory system in their GL accounts often have sophisticated inventory systems outside of the GL for tracking the items they purchase, produce, sell, and have on hand. In SummaryThe periodic inventory system uses an occasional physical count to measure the level of inventory and the cost of goods sold (COGS). The perpetual system keeps track of inventory balances continuously, with updates made automatically whenever a product is received or sold. A periodic inventory system is an inventory control method where the inventory status is updated at the end of a specific period rather than after every sale and purchase. In contrast, In a perpetual inventory system inventory status is continuously updated after every sale and purchase. This method updates data in real-time and businesses are used a computerized inventory management system. Periodic Inventory System vs Perpetual Inventory SystemWhat is a periodic inventory system:In a periodic inventory system inventory is physically counted and updated at the end of a period. Physically inventory counting is time-consuming, so businesses do this once in a period. Before doing a periodic update, the system shows the previous inventory balance recorded in the previous period. Under a periodic inventory system:Under a periodic inventory system, inventory is counted at the end of a period. Periods may be monthly, quarterly, or annual based on their business type, size, and accounting strategies. Periodic inventory method:A Periodic inventory system is following a simple method. Inventory is counted once in a period. The cost of goods sold in that period is counted by taking the inventory status at the beginning of a period, adding new inventory purchases during the period, and deducting the ending inventory. Costs of goods sold of a period= (Beginning Inventory + Purchase for the period) – Ending Inventory Periodic system accounting:Mr. Mohammad has a business or a company using a periodic inventory system and his business period starts on Jan. 1 and ends on Dec. 31(Once a year). In the last year (supposedly 2021), the ending or closing inventory was $50,000 and that was the beginning inventory for this year 2022. This year from Jan. 1, 2022, to Dec. 31, 2022, Mr. Mohammad purchase $75,000, and after-sales this year on Dec. 31, 2022, physically counting inventory found $65,000. So, the Costs of goods sold are found in 2022 : After finishing a period and before starting the next one, purchase inventory is recorded in the purchase account, and these are shifted to the inventory account in the next periodic update. The periodic inventory system updates the general ledger account Inventory at the end of the period. When you use a periodic inventory system:Businesses that don’t need current inventory status instead it’s enough to keep tracking inventory in period periods and can use a periodic inventory system. It works well for having a small number of inventory transactions looking to keep costs low. Since physical inventory counting is time-consuming, a periodic inventory system is suitable for businesses having a small amount of inventory where it’s easy to complete a physical count. The periodic inventory system uses businesses having few inventory items and few inventory item units sales per month such as art galleries and car dealerships.

The periodic inventory system is a simple, easy, and cheaper solution; but is not given real-time inventory status and is not fit for large businesses having so many products.

But, when you don’t need a perpetual system and a periodic system is enough, It gives you a simple, easy, and cheaper inventory management solution.

Disadvantages of the periodic inventory system:A periodic inventory system may well fit some particular businesses, but it’s not fit most businesses having large numbers of products, high sales volumes, and need real-time inventory status.
What is a perpetual inventory system:A perpetual inventory system is a real-time inventory management system where inventory status is continuously updated after every inventory movement including purchases, sales, and returns. When physically entering or leaving an inventory we enter data on a perpetual system and the system shows the inventory status. Here, we don’t count physical inventory every day rather we physically count inventories and match it with the system when making an audit which is called inventory reconciliation.

First-In, First-Out (FIFO):First-In, First-Out (FIFO) is one of the most common methods of inventory management. Under this method, you sell first that product which is purchased first means first enter, first out. Last-In, First-Out (LIFO):Last-In, First-Out (LIFO) is the opposite of First-In, First-Out (FIFO) where the last inventory is sold first especially using restaurants, food & beverage industries to give customers fresh & spicy tastes. In this method, some products spoil, and the loss, for this reason, will be recovered with profits of sold items. Weighted Average Cost:With the weighted average cost method cost of goods sold(COGS) is calculated on average. Weighted Average Cost Per Unit = Total Cost of Goods in Inventory / Total Units in Inventory Perpetual accounting:In the perpetual system, inventory records are updated constantly. But, in terms of accounting, we generate reports(like balance sheets, income statements, and cash flow statements) for an accounting period(like a fiscal year). Advantages & disadvantages of perpetual inventory system:While a perpetual inventory system gives real-time data, actual demands, and supply status, and ensures better customer services, a perpetual inventory system’s disadvantage is it’s expensive in terms of technology and manpower.
