The Ultimate Guide to Perpetual Inventory Systems: Benefits, Implementation, and Best Practices
For example, optical scanners are used in markets to keep track of inventory quantities, but at the end of the accounting period, a physical inventory is performed. However, even with such sophisticated equipment, perpetual records may be kept only in units, with the cost of ending inventories and goods sold determined by the periodic inventory system. Before the rise of digital technology, companies avoided perpetual inventory systems due to the time-consuming nature of the manual work involved. ShipBob’s fulfillment technology comes with built-in inventory management tools, including demand forecasting, order management, and data and analytics. Merchants can track SKU velocity, track storage costs, and even calculate the ideal distribution of inventory across ShipBob’s network. A perpetual inventory system will learn from the sales data of the past 4 years, and automatically raise your reorder threshold from 25 units to 50 units.
Having more accurate tracking of inventory levels also provides a better way of monitoring problems such as theft. 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. Utilize historical sales data and market trends to forecast demand for various products.
- Historical inventory and sales data can be used to predict future sales cycles and ensure that you have an optimal amount of inventory during different times in the season, such as the holidays.
- Periodic systems can have discrepancies due to shrinkage (like theft or damage) that occur between counts.
- Unlike a perpetual inventory system, it doesn’t provide daily data regarding inventory levels.
- 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.
Perpetual inventory systems offer a powerful tool for businesses seeking to streamline operations and gain a competitive edge. By providing real-time data and automating tasks, these systems can significantly improve inventory accuracy, reduce stockouts and overstocking, and boost profitability. However, it’s important to remember that perpetual inventory systems are not a one-size-fits-all solution, so you should consider your business needs, budget, and technical capabilities before implementing one. A perpetual inventory system is a method of continuously tracking inventory levels and transactions in real time.
Records data accurately in real-time
In the perpetual system, we need to record the COGS at the same time as we record the sale. This entry must be made every time there is a sale, which is why the perpetual system should only be used with accounting software that will make the necessary calculations. A perpetual inventory system tracks goods by updating the product database when a transaction, such as a sale or a receipt, happens. Every product is assigned a tracking code, such as a barcode or RFID code, that distinguishes it, tracks its quantity, location and any other relevant details. Other businesses that need perpetual inventory include those that specialise in drop shipping, where the manufacturers ship directly to customers or those who specialise in trade and distribution. Understanding which stock is available at a given time requires constant updates or a perpetual system.
What is the difference between a perpetual and periodic inventory system?
The perpetual inventory system is a reliable way to keep track of inventory in real-time. In this article, we’ll share what a perpetual inventory system is and how it works.

Inventory management formulas can tell you when to order more inventory, how much to order, the lead time needed before placing an order and how much stock you require to keep in safety.
With real-time updates, inventory holding costs and inventory replenishment are controlled and minimized. Since perpetual inventory systems automate many processes that would be manual, it can save on labor costs. The goal of using the WAC is to give every inventory item a standard average price when you make a sale or purchase. In a perpetual system, you would not calculate the WAC using a formula for a specific period. You can use WAC to calculate an average unit cost, COGS for a period and ending inventory for a period.
Reduced Inventory Carrying Costs
Retail businesses, whether operating physical stores or online platforms, commonly use Perpetual Inventory Systems. With the constant flow of sales, returns, and restocking, it is essential for retailers to have accurate and up-to-date inventory data to prevent stockouts or overstock situations and to maintain smooth operations. Effective inventory management is crucial for the success of any business that deals with products or materials. Maintaining optimal inventory levels, avoiding stockouts, and minimizing carrying costs are essential to ensure smooth operations what is perpetual inventory system and maximize profitability.
Perpetual system continuously upgrades sales and purchase records on the software. A perpetual inventory system allows for quick identification and resolution of issues such as stock discrepancies or data entry errors. Since updates occur in real-time, businesses can promptly address any inconsistencies that may arise. In contrast, a periodic inventory system only identifies problems during physical inventory counts at specific intervals, making it difficult to pinpoint when an issue occurred and delaying its resolution. The software can always provide the COGS in a perpetual inventory system as it maintains a running tally of transactions.
FIFO (first-in, first-out) is a cost flow assumption that businesses use to value their stock where the first items placed in inventory are the first items sold. So the inventory left at the end of the period is the most recently purchased or produced. When you sell products in a perpetual inventory system, the expense account increases and grows the costs of sales.

Similarly, returns and adjustments are tracked, with the system updating the inventory accordingly. Periodic physical counts are conducted to reconcile the recorded quantities with the actual stock on hand. The Perpetual Inventory System also calculates the Cost of Goods Sold (COGS) continuously, allowing for accurate financial reporting. The two systems of maintaining inventory are perpetual and periodic inventory systems.
