Methods Under A Periodic Inventory System

On January 1, the store records in the purchases account the beginning balance of inventory as $15,520. From January 1 through March 31, the store orders three shipments of additional envelopes, each at a cost of $2,250. For any business that carries inventory, or products stored for future sale, it is necessary to keep track of what is currently on hand. Some businesses keep track of inventory using a periodic inventory system.

For 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. A periodic inventory system only updates the ending inventory balance in the general ledger when a physical inventory count is conducted.


However, even in the perpetual inventory system, you will sometimes need to count stock to make sure that the virtual stock count aligns with the real inventory whenever there are discrepancies in the on-hand stocks in real. Similarly, whenever products are coming into the inventory, the workers can scan those products’ barcodes with RFID scanners, and the inventory count gets updated instantaneously. Periodic inventory system allows a poor control over inventory of a business where you are not accounting for your lost, wastage, scrap units of inventory. As periodic inventory is as old as history itself, it is also quite primitive. Even though it is a reasonable choice for companies just starting out, it has some disadvantages that could become issues in the long run. When a purchase is placed to a vendor and you receive the invoice, it is recorded in an asset account, showing the sum of purchased goods which have not yet been received . A perpetual approach gives a more detailed and current oversight of both stock and COGS, allowing companies to make business decisions based on up-to-date information and stock levels.

Determining the cost of the ending inventory and the cost of goods sold helps determine the periodic income and financial position. Preparing financial statements under the periodic inventory system means calculating the cost of goods sold during the period and the ending inventory.

What Are The Advantages Of Using A Periodic Inventory System?

Errors in estimating COGS –Assumptions of COGS, products, and availability of the products have to be made between the period when the stocktake is done. These estimations can be deceiving, and you only know the real figures when you carry out a physical inventory count. There are again three types of cost flow assumptions in periodic inventory system – FIFO, LIFO, and WAC.

At the end of the period, the physical count is done and calculations are made that determine the COGS, or the cost of goods sold, during the period. Notice that there is no particular need to divide the inventory account into a variety of subsets, such as raw materials, work-in-process, or finished goods. For example, XYZ Corporation has a beginning inventory of $100,000, has $120,000 in outgoings for purchases and its physical inventory count shows a closing inventory cost of $80,000. Note that this adjusting entry adjusts the merchandise inventory account to its proper ending balance in order to zero out the purchases account and create a cost of goods sold account.

The ending inventory is determined at the end of the period by a physical count of every item and its cost is computed using inventory calculation methods such as FIFI, LIFO and weighted averages. The total in purchases account is added to the beginning balance of the inventory to compute the cost of goods available for sale. Therefore, before any adjusting entries, the balance in the merchandise inventory account will reflect the amount of inventory at the beginning of the year, as indicated in the following T-accounts. The periodic inventory system uses an occasional physical count to measure the level of inventory and the cost of goods sold . As 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. When you conduct a physical inventory count at the end of the period, your closing inventory is worth $100,000. Your business spends $250,000 on inventory purchases over the accounting period.

Periodic Inventory Method

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. For these reasons, many companies perform a physical count only once a quarter or even once a year. For companies under a periodic system, this means that the inventory account and cost of goods sold figures are not necessarily very fresh or accurate.

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. The periodic method does not record the cost of the inventory sold for a particular sale. Furthermore, as the journal entries show, inventory purchases are not debited to the merchandise inventory account. 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.

Now inventory shrinkage happens for several reasons like damage, theft, loss. It is the difference between inventory you THINK you have on-hand and the stock you have on-hand. Perpetual inventory system quickly identifies any discrepancies due to theft or shrinkage and eliminates guesswork when it comes to setting replenishment levels because you always know the exact inventory level. Preventing stock-outs or overstocking–obviously, with higher inventory control, you’ll always be aware of the status of your inventory, helping you decide how much or how little you need.

How Does Periodic Inventory Work?

Starting 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. Because 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. It’s straightforward to calculate the cost of goods sold using the periodic inventory system. Less physical counts –you don’t have to worry about taking a physical count of inventory now and then because you know stock on hand. Saving inventory and storage costs-since you’ll always be up-to-date with inventory count, you won’t have to stock more than required, assuming sales will be higher. Imagine how much capital and storage costs you can save by maintaining only the necessary amount of inventory!

If your business has been expanding gradually and regular inventory counts seem confusing, then you can opt for the perpetual inventory system for smooth inventory management.

How does the periodic inventory accounting method track inventory and cost of goods sold?

This accounting method 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).

Small scale industries who have just started can use this method provided they are aiming for slow growth. Contra accounts generally consist of purchase discounts or purchases returns, allowances accounts,etc.. 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.

Amid the ongoing LIFO vs. FIFO debate in accounting, deciding which method to use is not always easy. LIFO and FIFO are the two most common techniques used in valuing the cost of goods sold and inventory. 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. In a perpetual system, goods count is limited, but they are of high value. In the periodic system, it is inventory count on the larger side with a lower value per unit value. The Meta company is a trading company that purchases and sells a single product – product X.

This way, all departments have the information they need at hand at all times. Because manufacturing companies often carry inventory items in the thousands, stocktake could be very time-consuming.

The method allows a business to track its beginning inventory and ending inventory within an accounting period. Once the ending inventory and cost of goods sold are clarified, the accounts require adjustment to reflect the ending inventory balance and the cost of goods sold. The total of the beginning inventory and purchases during the period represents all goods that the firm had available for sale. After subtracting the ending inventory from this total, the remaining balance represents the cost of the items sold.
