What are periodic inventory systems and when are they right for your business?

Aside from this initial record, no other updates are made to the inventory ledger until the next period. A periodic inventory system is a method of inventory valuation where a physical count of items is conducted at specific intervals, such as the end of the year or accounting period. Two methods used to manage inventory are periodic and perpetual inventory systems. Periodic inventory systems account for inventory at regular time-based intervals, while perpetual systems continuously update inventory after every transaction. A periodic inventory system is a form of inventory valuation where the inventory account is updated at the end of an accounting period rather than after every sale and purchase.

The method of accounting that supports this theory is the accrual method of accounting. There are two main accounting rules that govern the use of accounting periods, the revenue recognition principle and the matching principle. A calendar year with respect to accounting periods indicates that an entity begins aggregating accounting records on the first day of January and subsequently stops the accumulation of data on the last day of December. A company’s results may be reported every four weeks, resulting in 13 reporting periods every year.

Requirements for Accounting Periods

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. As discussed above, calculating the value of an inventory between one periodic accounting physical inventory count to the next, is done by starting with opening balances and adjusting for any accounting additions or subtractions to the account. 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.

It also wouldn’t make sense for small businesses that sell their inventory as a side project to use perpetual inventory. An appliance repair company selling two or three used refrigerators per month has no need to invest in an expensive point-of-sale system. 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.

Perpetual vs. Periodic Inventory: What’s the Difference?

Furthermore, periodic data from financial statements can be employed in the tax and other regulatory filing processes. To put the periodicity assumptions into practice, the company must first understand and decide which time frame (monthly or quarterly) is best for compiling financial statements. So, after an acceptable time frame has been determined, effective internal controls must be implemented to assure high-quality periodic financial statements.

In most cases, businesses selling fewer product lines or operating a single location will benefit from a simpler inventory accounting system. Sometimes, a business will experience goods lost in transit, purchase returns, product recalls, and the like. With periodic inventory, however, there’s no way to account for these unexpected changes. Periodic inventory systems start by taking a physical inventory count at the beginning of a specific period.

An Example of a Periodicity Assumption in an Income Statement

A company’s COGS vary dramatically with inventory levels, as it is often cheaper to buy in bulk, especially if it has the storage space to accommodate the stock. Periodicity also allows the manufacturer to report the revenues and net income it earned in each of the months during the two-year contract. If a company hasn’t earned revenue when cash is received, it will need to set up a deferred revenue account which indicates the revenue has not yet been earned. Fortunately, with the development of vaccine and other effort by global governments and organizations, the negative impact of COVID-19 is expected to subside and the global economy is expected to recover.

The following cost of goods sold, inventory, and gross margin were determined from the previously-stated data, particular to LIFO costing. The cost of goods sold, inventory, and gross margin shown in Figure 10.7 were determined from the previously-stated data, particular to FIFO costing. 1If the net method is applied by Rider Inc. the initial purchase entry is recorded as $245.

What role do periodicity assumptions play in business?

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. The main difference is that assets are valued at net realizable value and can be increased or decreased as values change. 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.

Inventory shrinkage happens when there is a discrepancy between the actual stock and the inventory list. That’s because it takes the inventory at the beginning of the reporting period and at the end unlike the perpetual system, which takes regular inventory counts. So if there is any theft, damage, or unknown causes of loss, it isn’t automatically evident.

Examples of the Periodicity Assumption

The credit entry to balance the adjustment is for $13,005, which is the total amount that was recorded as purchases for the period. This entry distributes the balance in the purchases account between the inventory that was sold (cost of goods sold) and the amount of inventory that remains at period end (merchandise inventory). The inventory at period end should be $6,795, requiring an entry to increase merchandise inventory by $3,645. Cost of goods sold was calculated to be $9,360, which should be recorded as an expense. Beginning merchandise inventory had a balance of $3,150 before adjustment.

If inventory is central to your business, it must be managed, and to do that it, must be measured. Using perpetual inventory, you’re able to track and manage inventory as transactions happen, buying more inventory when necessary and zeroing in on the best prices. One advantage of the periodic inventory system is that counting inventory allows you to identify shrinkage (inventory that is lost, stolen, or damaged).

Doing a physical count of all your on-hand inventory items increases the likelihood of human error. The total inventory count may be incorrect or there could be errors in valuation. To prevent this, check for any discrepancies or numbers that seem much higher or lower than expected after taking stock of all inventory.
