What is a Perpetual Inventory System? And How it Differs from a Periodic Inventory System

‍The Basics: What is a Perpetual Inventory System?

A perpetual inventory system, or PIS for short, is an inventory management method that allows businesses to keep track of their inventory on a real-time basis. With PIS, businesses can monitor the movement of their goods in and out of their warehouse as soon as it happens. This means that the inventory level is always up-to-date and accurate, making it easier for businesses to make informed decisions about their operations.

Why Use a Perpetual Inventory System?

One of the main justifications for employing a perpetual inventory system is its capacity to avert scenarios where stock becomes depleted. Given its real-time inventory tracking capabilities, businesses can readily ascertain when it's necessary to reorder items before they're completely out of stock.

For example, if a business discerns that a specific product is selling rapidly and only a small quantity remains in storage, they can promptly reorder to circumvent a stock deficiency. Moreover, a perpetual inventory system empowers businesses to refine their operations, minimizing labor-intensive tasks and errors inherent in traditional systems like periodic inventory methods or spreadsheets.

Automated systems like these enhance accuracy by reducing the possibility of errors such as inaccurate data entry or counting discrepancies, all while furnishing timely reports for informed decision-making. By efficiently managing the amount of inventory on hand, PIS helps optimize cash flow, minimizing the volume of idle inventory that absorbs working capital.

Through granting real-time transparency into goods' transit across various warehouses and supply chain channels, businesses can make more informed managerial decisions, thus improving their profit margins. After gaining a basic understanding of what a perpetual inventory system is and the reasons to adopt it, we can now delve into its workings.

In this system, regular updates to the inventory account are made via journal entries every time a transaction occurs. This ensures that the ending inventory balance accurately reflects the inventory on hand. One notable advantage of this system is that it provides an up-to-date record of the cost of goods sold without the need for a physical inventory count.

How does PIS work?

A perpetual inventory system operates as an inventory control method that meticulously tracks each movement of stock in real time by leveraging technology. This results in businesses maintaining a continuous, updated record of all inventory items, from their receipt to the point of sale. The principle behind the perpetual inventory method is the utilization of barcodes, scanners, and software systems that enable automated inventory tracking.

Upon receipt of a new item, it is scanned into the system and allocated a distinct barcode. The moment an item gets sold, its record is instantaneously updated and removed from the perpetual inventory system. This accounting system ensures precise inventory valuation and enhances inventory control, providing an accurate record from the beginning inventory to the present state. This system makes inventory management significantly more efficient and reduces the chances of errors or discrepancies.

How it differs from periodic inventory system

A periodic inventory system is an alternative method employed by businesses for inventory management. This system significantly contrasts with the perpetual inventory system, wherein each product movement is recorded in real-time. On the other hand, a periodic inventory system only updates its inventory records at specified intervals, typically at the conclusion of each accounting period.

Under the periodic system, businesses are required to perform a physical count of inventory at predetermined periods and amend their inventory records based on this count. Consequently, there may be instances when the periodic system's records accurately mirror the current stock levels, but there could also be times when they are off.

Consider a scenario where a specific product experiences a sudden surge in demand towards an accounting period's end, post the periodic inventory count. This surge wouldn't be indicated in the company's stock levels until the following count, and necessary adjustments are made. While both the perpetual and periodic systems aim for accurate inventory tracking over time, the perpetual inventory system offers businesses a more comprehensive and up-to-date understanding of their merchandise inventory status. This is why many organizations opt to use a perpetual inventory system for better inventory control, allowing them to update inventory records as transactions occur, providing a real-time and accurate inventory record.

Advantages of a Perpetual Inventory System

The Perpetual Inventory System (PIS) offers several advantages for businesses, foremost being the ability for real-time inventory tracking. This feature equips businesses with the power to make well-informed decisions related to product restocking and purchasing. By constantly maintaining current inventory levels, businesses can prevent situations of overstocking or stockouts, thereby optimizing resource utilization.

Another significant benefit of PIS is that it aids in cost control. It offers visibility into various inventory-related costs such as holding and ordering expenses. Upon scrutinizing this data, businesses may unearth opportunities for cost reductions in their inventory management procedures. For instance, they might discover that they are ordering too frequently or in quantities that are not optimal. Armed with the insights that PIS provides, they can alter their ordering habits to realize cost efficiencies.

Moreover, PIS significantly enhances operational efficiency. With real-time data at their disposal, managers can refine operations like shipping, receiving, and order processing, and significantly reduce the reliance on manual data entry or tracking. This system allows them to swiftly spot areas that may be experiencing slowdowns or bottlenecks. Consequently, they can proactively address potential issues, preventing them from escalating into serious problems. PIS ensures that the actual inventory matches with the accounting records, making it a robust system to track inventory.

The Advantages

One significant advantage of PIS is that it helps businesses make better-informed decisions quickly. The system generates detailed reports on sales patterns and customer behavior enabling managers to identify peak periods when customers purchase more often than others enabling them to target marketing activities during these periods effectively.

Another advantage is that PIS helps companies efficiently manage cash flow by optimizing procurement processes through real-time tracking of stock levels reducing the risk of stockouts and delayed production times leading to satisfied customers who receive their orders promptly. PIS reduces the dependency on manual systems empowering employees with automation tools allowing them more time for customer service tasks rather than spending hours manually recording inventory transactions.

Promoting Efficiency with Perpetual Inventory Systems

Streamlining warehouse operations is key to promoting efficiency, and PIS can help businesses achieve this. By providing real-time inventory data, PIS helps managers improve inventory forecasting and management, which leads to better purchasing decisions.

As a result, stock levels stay optimized for customer demand and reduces the need for manual intervention. Additionally, by minimizing delays in order processing and shipping/receiving processes through real-time tracking of inventory levels, PIS promotes timely deliveries resulting in satisfied customers.

With the system's automation features, employees can focus their time on customer service tasks rather than recording transactions manually. Perpetual inventory systems provide numerous benefits to business owners and managers.

From cost control to decision-making support and efficiency gains through streamlining warehouse operations. Embracing this technology offers businesses a competitive advantage as they optimize resources while providing quality products on time that meet their customers' needs.

Setting up a Perpetual Inventory System

Provide step-by-step instructions on how to set up a PIS

Implementing a Perpetual Inventory System

The struggle is real

Instituting a Perpetual Inventory System (PIS) often comes with its share of challenges, particularly if an enterprise has been reliant on a different approach previously. A pervasive issue encountered by many businesses is the employee resistance to change. This resistance may stem from a reluctance to embrace new technology or a lack of understanding on how to use it.

Such resistance can cause delays in the rollout of the new system and lead to errors in data entry, which could create complications in the long run. A second challenge lies in ensuring that all items in the inventory are correctly documented in the system. This involves accounting not only for physical items but also for those that may not be tangibly present, such as software or licenses.

The task of tracking these items and ensuring their accurate record in the PIS demands meticulous attention to detail. Additionally, comprehensive training for employees who will be managing this data entry is also crucial. It's noteworthy that a perpetual inventory system uses a computer system and specific perpetual inventory software to manage and update the inventory database. Consequently, the system calculates and maintains the inventory using this software, which implies that the inventory system requires a strong understanding and accurate application to function efficiently.

Overcoming challenges

To overcome these challenges, businesses should ensure that employees are properly trained on how to use the PIS before it is implemented.
