What is the difference between journal entry of purchases in periodic and perpetual inventory system?
|
Perpetual inventory system and periodic inventory systems are the two systems of keeping records of inventory. Show
In perpetual inventory system, merchandise inventory and cost of goods sold are updated continuously on each sale and purchase transaction. Some other transactions may also require an update to inventory account for example, sale/purchase return, purchase discounts etc. Purchases are directly debited to inventory account whereas for each sale two journal entries are made: one to record sale value of inventory and other to record cost of goods sold. Purchases account is not used in perpetual inventory system. In periodic inventory system, merchandise inventory and cost of goods sold are not updated continuously. Instead purchases are recorded in Purchases account and each sale transaction is recorded via a single journal entry. Thus cost of goods sold account does not exist during the accounting period. It is determined at the end of accounting period via a closing entry. Differences Between Perpetual and Periodic SystemFollowing are the main differences between perpetual and periodic inventory systems:
by Irfanullah Jan, ACCA and last modified on Mar 13, 2019 Mitchell Franklin; Patty Graybeal; and Dixon Cooper There are two ways in which a company may account for their inventory. They can use a perpetual or periodic inventory system. Let’s look at the characteristics of these two systems. Characteristics of the Perpetual and Periodic Inventory SystemsA perpetual inventory system automatically updates and records the inventory account every time a sale, or purchase of inventory, occurs. You can consider this “recording as you go.” The recognition of each sale or purchase happens immediately upon sale or purchase. A periodic inventory system updates and records the inventory account at certain, scheduled times at the end of an operating cycle. The update and recognition could occur at the end of the month, quarter, and year. There is a gap between the sale or purchase of inventory and when the inventory activity is recognized. Generally Accepted Accounting Principles (GAAP) do not state a required inventory system, but the periodic inventory system uses a Purchases account to meet the requirements for recognition under GAAP. IFRS requirements are very similar. The main difference is that assets are valued at net realizable value and can be increased or decreased as values change. Under GAAP, once values are reduced they cannot be increased again. Inventory Systems.

Therefore, one of the biggest assets on Gearhead’s balance sheet is inventory. The proper presentation of inventory in a company’s books leads to a number of accounting challenges, such as:
Proper application of accounting principles is vital to keep accurate books and records. In accounting for inventory, matching principle, valuation, cutoff, completeness, and cost flow assumptions are all important. Did Gearhead match the cost of sale with the sale itself? Was only inventory that belonged to the company as of the period end date included? Did Gearhead count all the inventory? Perhaps some goods were in transit (on a delivery truck for a sale just made, or en route to Gearhead). What is the correct cost flow assumption for Gearhead to accurately account for inventory? Should it use a first-in, first-out method, or last-in, first-out? These are all accounting challenges Gearhead faces with respect to inventory. As inventory will represent one of the largest items on the balance sheet, it is vital that Gearhead management take due care with decisions related to inventory accounting. Keeping in mind considerations such as gross profit, inventory turnover, meeting demand, point-of-sale systems, and timeliness of accounting information, what other accounting challenges might arise regarding the company’s inventory accounting processes? Inventory Systems ComparisonThere 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. Under a periodic inventory system, Purchases will be updated, while Merchandise Inventory will remain unchanged until the company counts and verifies its inventory balance. This count and verification typically occur at the end of the annual accounting period, which is often on December 31 of the year. The Merchandise Inventory account balance is reported on the balance sheet while the Purchases account is reported on the Income Statement when using the periodic inventory method. The Cost of Goods Sold is reported on the Income Statement under the perpetual inventory method.
A purchase return or allowance under perpetual inventory systems updates Merchandise Inventory for any decreased cost. Under periodic inventory systems, a temporary account, Purchase Returns and Allowances, is updated. Purchase Returns and Allowances is a contra account and is used to reduce Purchases.
When a purchase discount is applied under a perpetual inventory system, Merchandise Inventory decreases for the discount amount. Under a periodic inventory system, Purchase Discounts (a temporary, contra account), increases for the discount amount and Merchandise Inventory remains unchanged.
When a sale occurs under perpetual inventory systems, two entries are required: one to recognize the sale, and the other to recognize the cost of sale. For the cost of sale, Merchandise Inventory and Cost of Goods Sold are updated. Under periodic inventory systems, this cost of sale entry does not exist. The recognition of merchandise cost only occurs at the end of the period when adjustments are made and temporary accounts are closed. When a sales return occurs, perpetual inventory systems require recognition of the inventory’s condition. This means a decrease to COGS and an increase to Merchandise Inventory. Under periodic inventory systems, only the sales return is recognized, but not the inventory condition entry.
A sales allowance and sales discount follow the same recording formats for either perpetual or periodic inventory systems.
Adjusting and Closing Entries for a Perpetual Inventory SystemYou have already explored adjusting entries and the closing process in prior discussions, but merchandising activities require additional adjusting and closing entries to inventory, sales discounts, returns, and allowances. Here, we’ll briefly discuss these additional closing entries and adjustments as they relate to the perpetual inventory system. At the end of the period, a perpetual inventory system will have the Merchandise Inventory account up-to-date; the only thing left to do is to compare a physical count of inventory to what is on the books. 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. 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.
If a physical count determines that merchandise inventory is understated in the accounting records, Merchandise Inventory would need to be increased with a debit entry and the COGS would be reduced with a credit entry. The adjusting entry is:
To sum up the potential adjustment process, after the merchandise inventory has been verified with a physical count, its book value is adjusted upward or downward to reflect the actual inventory on hand, with an accompanying adjustment to the COGS. Not only must an adjustment to Merchandise Inventory occur at the end of a period, but closure of temporary merchandising accounts to prepare them for the next period is required. Temporary accounts requiring closure are Sales, Sales Discounts, Sales Returns and Allowances, and Cost of Goods Sold. Sales will close with the temporary credit balance accounts to Income Summary.
Sales Discounts, Sales Returns and Allowances, and Cost of Goods Sold will close with the temporary debit balance accounts to Income Summary.
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. The formula to compute COGS is:
where:
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. (Figure) summarizes the differences between the perpetual and periodic inventory systems. There are several differences in account recognition between the perpetual and periodic inventory systems.
There are advantages and disadvantages to both the perpetual and periodic inventory systems. Point-of-Sale Systems Advancements in point-of-sale (POS) systems have simplified the once tedious task of inventory management. POS systems connect with inventory management programs to make real-time data available to help streamline business operations. The cost of inventory management decreases with this connection tool, allowing all businesses to stay current with technology without “breaking the bank.” One such POS system is Square. Square accepts many payment types and updates accounting records every time a sale occurs through a cloud-based application. Square, Inc. has expanded their product offerings to include Square for Retail POS. This enhanced product allows businesses to connect sales and inventory costs immediately. A business can easily create purchase orders, develop reports for cost of goods sold, manage inventory stock, and update discounts, returns, and allowances. With this application, customers have payment flexibility, and businesses can make present decisions to positively affect growth. Advantages and Disadvantages of the Perpetual Inventory SystemThe 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. The biggest disadvantages of using the perpetual inventory systems arise from the resource constraints for cost and time. It is costly to keep an automatic inventory system up-to-date. This may prohibit smaller or less established companies from investing in the required technologies. The time commitment to train and retrain staff to update inventory is considerable. In addition, since there are fewer physical counts of inventory, the figures recorded in the system may be drastically different from inventory levels in the actual warehouse. A company may not have correct inventory stock and could make financial decisions based on incorrect data. Advantages and Disadvantages of the Periodic Inventory SystemThe periodic inventory system is often less expensive and time consuming than perpetual inventory systems. This is because there is no constant maintenance of inventory records or training and retraining of employees to upkeep the system. The complexity of the system makes it difficult to identify the cost justification associated with the inventory function. While both the periodic and perpetual inventory systems require a physical count of inventory, periodic inventorying requires more physical counts to be conducted. This updates the inventory account more frequently to record exact costs. Knowing the exact costs earlier in an accounting cycle can help a company stay on budget and control costs. 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. 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. (While our main coverage focuses on recognition under the perpetual inventory system, Appendix: Analyze and Record Transactions for Merchandise Purchases and Sales Using the Periodic Inventory System discusses recognition under the periodic inventory system.) Comparing Inventory Systems Your company uses a perpetual inventory system to control its operations. They only check inventory once every six months. At the 6-month physical count, an employee notices several inventory items missing and many damaged units. In the company records, it shows an inventory balance of $300,000. The actual physical count values inventory at $200,000. This is a significant difference in valuation and has jeopardized the future of the company. As a manager, how might you avoid this large discrepancy in the future? Would a change in inventory systems benefit the company? Are you constrained by any resources? Key Concepts and Summary

Thought Provokers(Figure)You have decided to open up a small convenience store in your hometown. As part of the initial set-up process, you need to determine whether to use a perpetual inventory system or a periodic inventory system. Write an evaluation paper comparing the perpetual and periodic inventory systems. Describe the benefits and challenges of each system as it relates to your industry and to your business size. Compare at least one example transaction using the perpetual and periodic inventory systems (a purchase transaction, for example). Research and describe the impact each system has on your financial statements. Decide which system would be the best fit for your business, and support your decision with research.

The perpetual system keeps track of inventory balances continuously, with updates made automatically whenever a product is received or sold.
What is the journal entry for periodic inventory system?In a periodic system, you enter transactions into the accounting journal. This journal shows your company's debits and credits in a simple column form, organised by date. Record the purchase of inventory in a journal entry by debiting the purchase account and crediting accounts payable.
What is the difference between the journal entry of sale for cash in periodic and perpetual?Under the periodic system, the inventory and cost of goods sold accounts are updated only periodically, but under the perpetual system, entries that recognize a transaction's effect on these accounts occur when the revenue from the sale is recognized.
What is the journal entry when using a perpetual inventory system?In a perpetual system, two journal entries are required when a business makes a sale: one to record the sale and one to record the cost of the sale. In the first journal entry, Marcia records the revenue from the sale, or the amount she earned from selling her products.
