What is a Perpetual Inventory System? How It Works, Pros & Cons

Additionally, maintain safety stock to account for unexpected fluctuations in demand or delivery delays. This ensures that you have sufficient inventory to meet customer demand without risking stockouts. Ava’s business uses the calendar year (starting on Jan. 1 and ending Dec. 31) for recording inventory. The company accountant valued the Jan. 1 beginning inventory of generic Acetaminophen at $49,000, or 4,900 bottles. During the year, generic Acetaminophen costs the company $40,000 for materials and labour.

In a perpetual LIFO system, the last costs available at the time of the sale are the first that software moves from the inventory account and debits from the COGS account. See the example LIFO perpetual inventory card below to get an idea of how it works. The retail sales for this product in this company were $25,000 from Jan. 1, 2019 to Jan. 15, 2019. A periodic inventory system is kept up to date by a physical count of goods on hand at specific intervals to calculate COGS using inventory valuation methods such as FIFO, LIFO, and weighted averages.

  1. The idea behind the perpetual inventory method is to turn stock-keeping into a constant, digitized, real-time activity instead of a periodic and manual one.
  2. Periodically compare your accounting books to on-hand inventory to ensure your inventory balances are correct.
  3. It would help if you were aware of the selling price, the purchasing price, and the affected accounts to record transactions in a perpetual system.
  4. After an accounting period, a periodic inventory system determines COGS in a lump sum following a physical inventory.

This helps identify discrepancies, minimize theft, and maintain accurate inventory records. The three cost flow assumptions that businesses use for this are FIFO, LIFO, and the Weighted Average Cost (WAC). Huge businesses have difficulty performing the cycle counts that are necessary for a periodic system. Further, an organisation with several retail locations may find it is easier to control inventory when there’s a regularly updated database of products.

The differences between perpetual and periodic inventory systems go beyond how the two systems function, although that is the main point of distinction. We have made clear the many facets and components of perpetual inventory systems, but we are yet to discuss how they are put to use in the real world. They offer a number of benefits across various industries – retail, manufacturing, food, or pharmaceutical, you name it! Let us evaluate how your business can leverage a perpetual inventory system to improve overall operations.

Step 2: Cost of goods sold is updated automatically

Barcodes or RFID (radio-frequency identification) scanners make this process quick and easy. The return of goods from customers to seller also involves two journal entries – one to record the sales returns and allowances and one to reverse the transfer of cost from inventory to COGS account. Both merchandising and manufacturing companies can benefit from perpetual inventory system. When you use perpetual inventory, the POS system automatically makes changes to your inventory levels.

Let’s say Ava, a product manager, wants to know if she is pricing generic Acetaminophen high enough to leave a healthy profit margin. If she calculates the COGS as $10 per 100-capsule bottle, she will need to price each bottle higher than $10 so her company can comfortably turn a profit. One of the features of the perpetual system is to provide the firm with information concerning its inventory levels. The process of accounting for perpetual inventories is shown in the following example. Every parcel that is delivered is first scanned, after which the balance is added to the current inventory levels.

So, employees can use the WMS to quickly scan the product whenever inventory is sent to a warehouse. The product will then automatically appear in the inventory management dashboard, available for sale on all sales channels. Computers and scanners may now be used to handle inventory monitoring systems.

On the other hand, detractors don’t necessarily note that reported stockouts without corresponding sales can signal theft or loss and trigger a physical inventory faster than with a periodic system. When deciding how to maintain control over physical inventory, it’s prudent to carefully weigh both the pros and cons of any system under consideration. Like all inventory management systems, inventory forecasting is a crucial aspect, as it informs accurate future business inventory needs. Let us delve further into the importance of inventory forecasting within a perpetual inventory management system. When it comes to inventory management, implementing a Perpetual Inventory System can be a game-changer for businesses seeking to stay competitive and efficient.

Transactions Recorded Under the Perpetual Inventory System

Under perpetual inventory system, the expenses that are incurred to obtain merchandise inventory are added to the cost of merchandise available for sale. These expenses are, therefore, also debited to inventory account under this system. The general examples of such expenses include freight-in and insurances expense etc. Each time the merchandise is sold, the related cost is transferred from inventory account to cost of goods sold account by debiting cost of goods sold and crediting inventory account. If your business has multiple locations with frequent inventory transfers, inventory management becomes much more complicated. It automatically creates a centralized inventory database across locations, cutting down the chances for error.

With a perpetual inventory system, you’re able to centralize inventory management, optimize stock levels, and much more. Moreover, periodic inventory systems typically require how to prepare an adjusted trial balance for your business employees to stop warehouse activity and take a physical inventory count. The process also involves regular inventory audits and other time-consuming manual activities.

This involves computing the cost of goods sold during the period and the appropriate cost of the ending inventory. It also has a direct impact on people and machinery use and capacity utilization. The system updates reorder points and generate the purchase orders necessary for restocking with zero human interference. Specifically, if you can afford to invest in the early setup costs of a perpetual system. Inventory management becomes extremely difficult if your company operates out of several sites.

The last transaction was an additional purchase of 210 units for $33 per unit. Ending inventory was made up of 30 units at $21 each, 45 units at $27 each, and 210 units at $33 each, for a total LIFO perpetual ending inventory value of $8,775. The first-in, first-out method (FIFO) of cost allocation assumes that the earliest units purchased are also the first units sold. At the time of the second sale of 180 units, the FIFO assumption directs the company to cost out the last 30 units of the beginning inventory, plus 150 of the units that had been purchased for $27.

With this application, customers have payment flexibility, and businesses can make present decisions to positively affect growth. A perpetual inventory system is superior to the more conventional periodic inventory system. Perpetual inventory systems allow immediate tracking of sales and inventory levels, except in cases where the perpetual inventory differs from the physical inventory count due to loss, breakage, or theft. A periodic inventory system relies upon having an accurate inventory count only when a physical count is taken. At all other times, a company using the periodic system does not know the exact number of units that it has in stock, which makes it inferior to the perpetual inventory method. Since businesses often carry products in the thousands, performing a physical count can be difficult and time-consuming.

This can be done manually using spreadsheets; however, modern companies often opt for specialized software solutions like QuickBooks, NetSuite, or TradeGecko. Real-time inventory data enables businesses to fulfill customer orders more efficiently. When a customer places an order, the system can immediately check the availability of the products. This streamlines the order fulfillment process, reducing delays and ensuring that customers receive their items promptly.

With the use of inventory management software, a perpetual inventory system tracks inventory levels and orders in real-time and centralizes the data in one place. As a small business owner, keeping track of inventory is an essential part of running your business. Read on to learn more about what is perpetual inventory, how perpetual inventory systems work, and the pros and cons of perpetual inventory.
