Small merchandising businesses can track their inventory with an inventory management approach known as the periodic inventory system. 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. Periodic inventory is normally used by small companies that don’t necessarily have the manpower to conduct regular inventory counts.

  • The periodic inventory approach has its advantages, especially when the stakes are low.
  • One of the worst things you can say about a periodic inventory system is that it can be exceedingly incorrect.
  • These companies often don’t need accounting software to do the counts, which means inventory is counted by hand.
  • As such, the periodic inventory system is most appropriate for small businesses that have smaller inventory balances, which makes it easier to do physical counts.
  • In the end, picking between a perpetual and periodic inventory system — and the right inventory valuation method — really depends on what works best for your specific business and resources.

This means there is no need for expensive or complicated equipment, just essential information collection tools – pen and paper. In contrast, perpetual inventory systems often involve the use of sophisticated software and technology to track inventory in real time. It continuously updates inventory records to account for purchases, sales, and other inventory-related transactions.

What is the difference between the periodic inventory and perpetual inventory systems?

In contrast, the perpetual inventory system gives you real-time inventory counts because it updates each time a unit moves in or out of your inventory. Under the periodic inventory system, all purchases made between physical inventory counts are recorded in a purchases account. When a physical inventory count is done, the balance in the purchases account is then shifted into the inventory account, which in turn is adjusted to match the cost of the ending inventory. This accounting method requires a physical count of inventory at specific times, such as at the end of the quarter or fiscal year. This means that a company using this system tracks the inventory on hand at the beginning and end of that specific accounting period.

  • The weighted average cost is based on the cost of the beginning inventory plus any purchases made during that period.
  • It continuously updates inventory records to account for purchases, sales, and other inventory-related transactions.
  • Unlike the perpetual inventory method, which updates inventory records in real time, the periodic system updates records at the end of an accounting period (typically on a monthly or annual basis).
  • 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.

Accountants then apply the balance to the beginning inventory in the following period. Logging entries are generated by software-assisted transactions from the inventory and cost of goods sold (COGS) accounts to the user-defined accounts. 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.

The periodic inventory system is ideal for smaller businesses that maintain minimum amounts of inventory. The physical inventory count is easy to complete, small businesses can estimate the cost of goods sold figures for temporary periods. Any business can use a periodic system since there’s no need for additional equipment or coding to operate it, and therefore it costs less to implement and maintain. Further, you can train staff to provide simple inventory counts when time is limited or you have high staff turnover. They can quickly count the goods they are working with, whereas a perpetual system, which provides a more accurate inventory, requires training staff on electronic scanners and data entry.

The periodic inventory system also allows companies to determine the cost of goods sold. 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 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.

Under a periodic review inventory system, the accounting practices are different than nonprofit statement of cash flows with a perpetual review system. To calculate the amount at the end of the year for periodic inventory, the company performs a physical count of stock. Organisations use estimates for mid-year markers, such as monthly and quarterly reports.

Hence, the system is easier to implement, requires little accounting knowledge, and records changes in inventory through very few simple calculations. Sales and expenses for these companies are easily manageable, so they tend to opt for a periodic inventory system, as it’s more cost-effective to implement. That’s why businesses with high sales volume and multiple sales channels use a perpetual inventory system, instead. Since some companies carry hundreds, and even thousands of merchandise, performing a physical count can be a tiring and time-consuming process. The perpetual inventory system cannot be manually maintained since it requires continual inventory tracking. In addition, because it is critical to register each order immediately, managers are constantly on the lookout for syncing inventory on the system.

What are the advantages of using a periodic inventory system?

As you can see, weighted average in a periodic system is a calculation done outside of the ledger. In this method, you calculate an average for the period instead of moving transactions over when the company bought or sold something during the period. The main benefits of employing a periodic inventory system are the ease of implementation, its lower cost and the decrease in staffing needed to run it. Simple counts on legal paper can suffice for collecting product data, especially if you only offer a few goods. A basic count during the day or week is often enough for a small business to get an adequate handle on their inventory.

Cost Flow Assumptions in Periodic Inventory

First, add up all of the transactions in the purchases account to get the total cost of all purchases. When calculating periodic inventory, you’ll also use a metric called cost of goods available. So, if you have 10 shirts available to sell and they cost $5 to produce, your cost of goods available is $50. 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. At the end of the year, a physical inventory count is done to determine the ending inventory balance and the cost of goods sold. More specifically, under a periodic inventory, the physical count of inventory and calculation of the inventory costs is done periodically, at regularly occurring intervals.

For instance, it may not provide real-time visibility into inventory levels, leading to potential stock-outs or overstocking situations. This additionally means that the COGS figure may not be as precise as in a perpetual inventory system which constantly updates inventory levels. As a result, the periodic inventory system may require additional internal controls to minimise errors and discrepancies during the physical counting process. Each business should carefully evaluate its needs and requirements to determine the most suitable inventory management approach. 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.

Understanding the Periodic Inventory System

In this article, we’ll take a look at what periodic inventory is, how to implement it, and how it can benefit your business. Record inventory sales by crediting the accounts receivable account and crediting the sales account. Record the total accounts payable purchase and accompanying discount in an entry together that debits the accounts payable and credits the purchase discounts account. This journal shows your company’s debits and credits in a simple column form, organised by date. One big negative, however, is that you are only collecting minimal information, usually just a discrete product count.
