It plays an integral role in business accounting by providing a point-in-time estimate of the cost to produce products sold by a company. If the company utilizes a perpetual inventory system, COGS is available on a continuous basis. With a periodic inventory system, COGS is calculated at the end of an inventory period. While perpetual inventory systems offer rich information for management, maintaining these systems is costly and time-consuming, unless the firm has completely computerized its inventory control system.
Understanding Perpetual Inventory Systems
For businesses in which transactions such as purchasing, selling, and moving inventory happen every second, perpetual inventory systems are invaluable in helping to keep track of what is going on at all times. However, perpetual inventory systems require manual adjustments in the event of theft, breakage, or unrecorded transactions. These are only required in periodic inventory system to update inventory and cost of goods are advertising and marketing expenses fixed or variable sold while the perpetual inventory system does not require closing entries for inventory account. It’s critical for organizations to stay current with effective methods in the business world of inventory management. The perpetual inventory system emerges as a game-changer, offering real-time tracking of stock levels.
What System Is More Effective, Perpetual Inventory or Periodic Inventory?
- Here, the transactions are checked in bulk, like in periodic systems; there is also no need for physical counting unless there are doubts regarding breakage or theft.
- This system allows businesses to more accurately track their inventory, as well as identify when they need to order more of a particular item.
- Starting in the 1970s digital computers made possible the ability to implement a perpetual inventory system.
- This process involves manually counting each inventory item and comparing it to the quantity recorded in the inventory system.
- The journal entries used when bookkeeping in the perpetual inventory system are different compared to the ones used in a periodic system.
To calculate inventory, companies need to set up a system where every piece of inventory is entered into the system and deducted from the system as it’s sold. This requires the use of point-of-sale terminals, barcode scanners, and perpetual inventory software to update estimated inventory with every product purchase and sale. Because perpetual inventory systems lack the ability to account for loss, breakage, or theft, a periodic (physical) inventory can still be necessary. System software provides real-time updates to inventory through the use of barcode scanners or other computerized records of product acquisition, sales, and returns as they occur. There are key differences between perpetual inventory systems and periodic inventory systems.
How do retailers benefit from perpetual inventory systems?
It includes the cost of labor and materials related to production or manufacturing, but not distribution or sales costs. The only reason businesses use the periodic inventory system is when they deal with high volumes of low-value products or when the amount of inventory is so small that a visual review is sufficient. Start-up businesses that cannot afford the cost of technology and training might also fall back on the periodic inventory system. Some pros of perpetual inventory include its ability to provide up-to-date inventory information instantly, its easy access system, and how it reduces the requirement to count physical inventory. Perpetual inventories are the solution to such an issue; giving accurate and updated information about inventory levels and COGS allows them to check on discrepancies in real time. Most small and medium-sized companies use the periodic inventory system, which involves scheduled inventory audits throughout every year.

In earlier periods, non-continuous, or periodic inventory systems were more prevalent. Starting in the 1970s digital computers made possible the ability to implement a perpetual inventory system. This has been facilitated by bar coding and lately radio frequency identification (RFID) labeling which allows computer systems to quickly read and process inventory information as part of transaction processing.
The downside of this is that the perpetual inventory management system is relatively difficult and more expensive to set up since you’d require investment in inventory software, computers and expertise. Perpetual inventory system allows you to identify when the stock is running out and gives accurate information about inventory value and COGS. These allow you to investigate theft, discrepancies, shrinkage and even count errors immediately and adjust the records accordingly. This gives stakeholders a clear picture of the profitability throughout the year. This is especially important if certain financial records have to be kept for banks and other lenders.
It is far more sophisticated than the periodic system of inventory management. A perpetual inventory system uses point-of-sale terminals, scanners, and software to record all transactions in real-time and maintain an estimate of inventory on a continuous basis. A periodic inventory system requires counting items at various intervals, such as weekly, monthly, quarterly, or annually. A perpetual inventory system continuously updates inventory levels as you buy and sell goods. It saves all product data into a single system, both for online and physical retail stores, making it easy for you to keep sufficient stock on hand. You never run out of inventory, because the system constantly reorders products as counts diminish.
You may forget to record a transaction or experience employee theft at your business. Be sure to occasionally check your actual inventory quantities to compare totals. The periodic inventory system relies on physical inventory count to determine your ending inventory and cost of goods sold. Perpetual inventory is computerized, using point-of-sale and enterprise asset management systems, while periodic inventory involves a physical count at various periods of time. The latter is more cost-efficient, while the former takes more time and money to execute.
Changes in inventory are accurate (as long as there is no theft or damage to any goods) and can be easily accessed immediately. The cost of goods sold (COGS) account is also updated continuously as each sale is made. The information collected digitally is sent to central databases in real time. In this case, book inventory would be exactly the same as, or almost the same, as the real inventory.

Perpetual inventory is a system of tracking inventory purchases and sales on a continual basis. An example of this would be a retail store that keeps track of their inventory in real time as it is purchased and sold. Every time a product is sold, the amount of inventory in the store is updated to reflect the sale. The store also keeps track of incoming shipments of inventory to make sure that the amount in stock is accurate. If you use the periodic inventory system, it’s difficult to track the accounting records for an inventory-related error as the information is aggregated at a very high level.
As you see, a perpetual inventory system can reduce stockouts and increase cash flow. With the right tools and processes in place, you can set up an inventory control system that automatically replenishes stock and lowers the cost of inventory management, with no human intervention or ordering errors. A perpetual inventory system keeps continual track of your inventory balances.
A perpetual inventory system is a method for tracking inventory that is updated in real-time. Every time an item is sold, the inventory system is updated to reflect the new quantity of the item. This system allows businesses to more accurately track their inventory, as well as identify when they need to order more of a particular item. It also helps prevent overstocking and understocking of items, as well as reduce the amount of time spent manually tracking inventory. The perpetual inventory system involves the continuous updating of inventory records.
