The Perpetual Inventory System is a method of accounting for the number and value of goods on hand at any time. It helps with the vital task of keeping track of inventory levels so that we can timely replace goods when they run out and to ensure that we record the correct amount of revenue and the corresponding cost of sales (cost of goods sold).
The Perpetual Inventory System is crucial because it allows companies to keep track of their inventory levels and ensure they are always stocked with the necessary goods.
How Does the Perpetual Inventory System Work
Under the Perpetual Inventory system, businesses keep a running tally of the number of goods they have on hand at all times. This information is typically tracked using software designed specifically for this purpose. The software records sales and purchases as they happen via point-of-sale (POS) and enterprise asset management systems.
When we sell a good, the software automatically deducts it from the total number of goods on hand and generates the necessary accounting records. When a new shipment arrives, the software will add it to the balance and generate the required goods receipt notes (GRNs). There’s no need to keep a record of goods on hand as such reports are auto-generated. The system lets businesses know how many goods they have and easily track inventory levels in real-time.
The system also ensures that the company recognizes the correct revenue and corresponding cost of goods sold (COGS).
Who Uses a Perpetual Inventory System?
Businesses that deal in goods that are frequently bought and sold, such as retail stores, often use the Perpetual Inventory System. These businesses need to keep track of their inventory levels to ensure that they are always stocked with the necessary goods. The Perpetual Inventory system helps companies track the number and value of goods on hand in real-time.
Manufacturing companies also use the Perpetual Inventory System to track the level of raw materials they have on hand. This information is essential so companies can plan their production schedules and ensure they have enough raw materials to meet production demand.

Implementing the Perpetual Inventory System in Your Business
If you are a business owner who deals in frequently bought and sold goods, you should consider implementing the Perpetual Inventory system.
You can implement it in various ways, depending on the needs of your business. You may track inventory semi-manually or use fully-automated software to help you keep track of your goods. No matter how you implement the system, it is crucial to ensure that all your employees receive adequate training on how to use it.
Remember a few things when implementing the Perpetual Inventory System in your business. You must ensure that you have enough space to store all your inventory. You also need to create a process for replacing goods when they run out. It is also vital that your employees know the importance of keeping accurate records of inventory levels. Most importantly, ensure you have the proper software to keep track of your good.
Additionally, although the Perpetual Inventory System effectively eliminates the regular physical stock counts typical for a Periodic Inventory System, most local legislations require at least one physical count per year. Make sure to have the necessary procedure to reconcile actual goods on hand and what the inventory module says.
