What does a perpetual inventory system require?
The backbone of your firm is inventory. To meet client demand, you must maintain enough inventory on hand but not so much that your storage expenses are out of control. An inventory system can be used in this situation. Show
Merchandise businesses can record their inventory with either a periodic or perpetual inventory system. A periodic inventory system records merchandise transactions periodically, usually at the end of the year. Whereas with a perpetual inventory system, all transactions, along with inventory costs and sales of merchandise get recorded immediately as they occur. Perpetual Inventory System: Definition & Examples for BusinessReal-time inventory tracking is dependable with the perpetual inventory system. Poor inventory management can result in a wide range of problems. There are a lot of potential issues. Yet, these are a few to provide you with an overview of the possibilities:
These are problems that could have a significant impact on how your organization runs. In this guide, we will be explaining what a perpetual inventory system is, its advantages, and whether or not it is the right inventory management practice for your small business accounting.

Increasingly, warehouses and the retail sector adopt perpetual inventory methods. It can minimize understatements due to missing inventory. It can also reduce overstatements due to phantom inventory. Companies that use a material requirement planning (MRP) system for production must also maintain perpetual inventory. Companies can use the following formula to calculate their perpetual inventory's ending inventory: Ending Inventory = Beginning inventory + Receipts - Shipments When using this approach, a business needs to make more effort to maintain thorough records of the products it has on hand. Instead, purchases are noted as debits to the inventory database. Direct expenditures for labor and materials are included in the cost of products sold. It also contains direct factory overhead expenses. A firm maintains records of its inventory through routine physical counts. It is done under a periodic inventory system, which is different from a perpetual inventory system. Understanding Perpetual InventoryA 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. The perpetual inventory does not need manual adjustment by the company's accountants. Transactions Recorded Under the Perpetual Inventory SystemBusinesses that use a perpetual inventory system count their inventory and document transactions. It includes:
When combined, these transactions show the current inventory levels. What Is a Perpetual Inventory System?A perpetual inventory system is an inventory management method that records each sale or purchase of inventory in real-time, through automated software. With a perpetual inventory system, each sale or purchase of merchandise is updated on a real-time basis automatically, thus providing you with a full financial picture of your inventory levels.
For instance, the financial and accounting departments depend on real-time inventory data. Integrating inventory management with financial systems helps ensure correct tax and regulatory reporting. Inventory might make up a significant part of your reported assets. Salespeople can manage expectations and deliver a better customer experience. It has a direct influence on your reputation. Marketers may position the business to meet anticipated customer demand. It is done by understanding customer behavior in the context of historical trends.

Increased Usage of Perpetual Inventory SystemIn the past, perpetual inventory systems were not commonly employed. It took time to reliably and swiftly record and analyze the vast volumes of data. Besides, technological advancements have enhanced business and accounting procedures recently. Computers and scanners may now be used to handle inventory monitoring systems. It makes perpetual inventory tracking less onerous. Who Uses a Perpetual Inventory System?When business owners or management need up-to-date information about inventory levels, then using a perpetual inventory system is the way to go.
When Would You Use a Perpetual Inventory System?Perpetual inventory systems are helpful for individuals who must constantly comprehend margins and profitability. Big businesses use a perpetual inventory system with lots of products or by companies who seek to grow new businesses over time.
The price charged is also recorded by the software. 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. The cost to the client of the product is its selling price. The costs related to the product, such as shipping, receiving, and storage expenses, are included in the purchase price. Periodic vs Perpetual Inventory SystemWhile we explained above the main difference between periodic and perpetual inventory systems, we only covered some core features that differentiate the two. With a perpetual inventory, all transactions involving costs of merchandise get recorded immediately as they occur. For instance, take grocery stores - each time a product is bought and scanned, the system updates inventory levels in the database. In a periodic inventory system, on the other hand, reports of inventory and cost of goods sold aren’t kept daily, but periodically, usually at the end of each fiscal year, or at the end of each month. You can choose the system depending on your items' nature, perishability, and physical handling. It is also based on how big or tiny and how much room they take up. The way your business receives and stocks the product also affects its nature. Some products are unitized because they come in separate bins and have little pieces. The perpetual and periodic systems also differ in the following additional ways: Updating Your Accounts: A perpetual system allows for ongoing inventory and general ledger updates with each transaction. Updates to the general ledger only take place during physical counts in a periodic system rather than based on transactions. Determining Cost of Goods Sold (COGS): In a perpetual system, the software system keeps track of transactions in real time. It can thus always offer COGS. After an accounting period, a periodic inventory system determines COGS in a lump sum following a physical inventory. Before the end of the accounting period, it is impossible to decide on an exact COGS. Implementation Method: Permanent systems need to be implemented using the software. It is because of the vast number of transactions they keep track of. Periodic systems enable manual implementation without the need for any software. Record Transactions: A perpetual inventory system requires software because it is impossible to maintain records manually. There may be thousands of transactions to track. Yet, the software is optional for a periodic system. In a periodic inventory system, you might manually keep track of your inventory. Cycle Counting: Cycle counting is the practice of businesses counting segments of their inventory. The goal is to do an entire inventory throughout a set period. They only count some of their stock at a time, but they make tiny adjustments based on the results. Businesses only use cycle counting, also known as sampling, in a perpetual system. Because they cannot establish a baseline while using a periodic inventory system, they do not use cycle counting. Stock-keeping Method: With perpetual inventory, you can use alternate counting techniques, like cycle counting. It is not possible with periodic systems. Cycle counting lets you divide your inventory into several pieces for individual counting. It then assimilates that data into your central databases. In this manner, it is unnecessary to count the entire inventory simultaneously. Recording Purchases: Purchases are entered in either the inventory account for raw materials or the merchandise account in a perpetual system. Without including any unit-count data, investments in a periodic system are logged into the purchases asset account. Investigating: A perpetual system makes available transactions at a detailed level. As a result, it is simple to conduct inquiries into inventory-related problems. These analyses are more complex in periodic systems since the system accumulates data at a high level. It is challenging to identify process errors using this data. Even by GAAP requirements, perpetual or periodic systems are suitable for any business. Each is better suited to various sizes of enterprises. Because permanent systems are more timely, they are better suited to companies with significant sales volumes. Perpetual methods are also better appropriate for businesses with many retail locations. Periodic systems make it harder for these kinds of groups to make decisions. Being able to check inventory levels and the cost of goods sold, in real-time, can save your employees and your business a considerable amount of time and money. If you want to learn more about the details and uses of periodic inventory, head over to our guide on the periodic inventory system. Perpetual Inventory vs Book InventoryThe quantity of stock that a company has on hand as of the date of its books is referred to as book inventory.
Metrics to Consider While Choosing a SystemThere are arguments for and against perpetual inventory, as you might have inferred from the section above. The viability of each case depends on specific aspects of your company: The Volume of Transactions and Inventory Which of these two approaches is best depends mainly on the quantity of your inventory. The advantages of the perpetual inventory system outweigh the drawbacks for most organizations with extensive stocks.
Businesses like auto dealerships and diamond businesses with the modest transaction and inventory volumes but high-value products often find the periodic technique easier to use. It is especially true when ensuring there are no anomalies. Location Diversity Inventory management becomes extremely difficult if your company operates out of several sites. It moves its stock frequently.
Budget The most apparent factor is undoubtedly your financial situation. Specifically, if you can afford to invest in the early setup costs of a perpetual system. The infrastructure needed to implement this strategy accurately is substantial. It comes at a cost that small enterprises might not be able to bear. How Does the Perpetual Inventory System Work?Every time merchandise is bought or sold, the perpetual inventory system will update inventory levels automatically. This constant updating allows businesses to be aware of their best-selling goods and services and what inventory is running low on supply. Compared to a periodic inventory system, this form of inventory accounting offers a more precise and effective way to account for inventory. Here is a detailed explanation of how this kind of inventory system functions. Here is the step-by-step process of how the automation of the perpetual inventory system works. Step #1: Update inventory levels on the point-of-sale system As soon as a product is sold, the inventory management system integrated with the POS (point-of-sale) system debits the primary inventory across all sales channels. A point-of-sale or POS system is the hardware that enables businesses to make sales at a physical store. Through a barcode scanner, the POS system calculates the price of the item and updates the inventory count to show that the item is sold. After the customer pays through a credit card or cash, the POS system processes the payment, creating a digital receipt. Step #2: Update Cost of Goods Sold The cost of goods sold (COGS) is automatically updated and recalculated using the information from the previous phase. You can use the first-in, first-out (FIFO), last-in, first-out (LIFO), or weighted/moving average costing method that you like. Step #3: Reorder Point Automation The sale also triggers an automatic update on inventory levels. Businesses dealing with inventory have minimum required stock levels they need to maintain for every type of good. Whenever a stock amount falls below this minimum, the system sends a notification suggesting you order more stock. This is known as a reorder point. A perpetual inventory system uses the business's historical data to automatically update these reorder points and keep inventory levels optimal at all times. Step #4: Purchase Order Automation The system updates reorder points and generate the purchase orders necessary for restocking with zero human interference. In other words, it can be set up to automatically issue purchase orders whenever stock levels fall below the required threshold. Step #5: Warehouse Management Software A perpetual inventory system comes with a warehouse management system (WMS), software designed to support and optimize distribution management. 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. How Does a Perpetual Inventory System Track Inventory?When a transaction, such as a sale or a receipt, the product database is updated as part of a perpetual inventory system. The perpetual inventory system keeps track of the goods.
The database subtracts one of these products from its count each time a consumer purchases one. The store manager can check the database any time to see how much of that product is currently in stock and whether more needs to be ordered. An effective inventory control system is required. For instance, the system must ensure that workers quickly scan any new inventory. Physical counts to reconcile the database are uncommon but essential. Over time, theft, loss, and damage can affect the genuine inventory total. Formulas in Perpetual InventoryWhen to order more inventory? How much to order? How much is lead time required before placing an order? And how much stock do you need to maintain on hand for safety? It can all be determined by using inventory management formulas. FIFOFIFO stands for First-In-First-Out, and it’s based on the assumption that the first merchandise bought is the first one sold. To better visualize this method, you can think of FIFO as a queue. The first person that’s queued, is also the first person to go out. Businesses value their stock using the FIFO (first-in, first-out) cost flow assumption. This assumption states that the first products placed in inventory are also the first items sold. As a result, the inventory that is still on hand after the time period is the most recent. A cost flow assumption is an inventory accounting technique determining the value of the ending inventory and the cost of goods sold. It uses the original value of products from the beginning inventory of a period and purchases of new inventory made during that period.
LIFOThe LIFO method, or Last-In-First-Out method, assumes that the most recently purchased merchandise is sold first. A better way to visualize LIFO is by imagining a stack of plates. The first plate (the one you placed at the bottom), will be the last one to go out because you’ll first have to remove all the plates that were placed on top of it. Weighted Average MethodBusinesses value their inventory using a Weighted Average Cost (WAC) cost flow assumption. The average cost of goods sold for all inventory is known as WAC. Accountants carry out this differently in a perpetual system as opposed to a periodic system. It is also known as the moving average cost method. Every inventory item should have a standard average price when you sell or buy something utilizing the WAC. In a perpetual system, you wouldn't determine the WAC using a formula for a particular time period. The average unit cost, COGS for a time period, and ending inventory for a time period can all be calculated using WAC. Formula: Cost of goods available for sale / Total number of units in inventory Economic Order Quantity (EOQ)Economic order quantity, or EOQ, is a formula that helps organizations determine the correct order amount. It reduces factors like expenses, warehouse space, and stockouts. EOQ = √2DS/H D =Demand in units per year S= Setup costs (per order, generally including shipping and handling) H = Holding cost per unit per year Finished GoodsThe stock accessible to clients for purchase and can be fulfilled is finished goods inventory. Sellers can determine inventory cost using the finished goods inventory formula. Formula: (COGM – COGS) + Value of Previous Year's Finished Goods Cost of Goods Sold (COGS)In a perpetual inventory system, the expenditure account grows, and sales costs rise as you sell things. The costs of sales, often known as the cost of goods sold (COGS), are the outright costs related to producing commodities over a specific period. These costs do not include distribution or sales costs, only labor, and material costs. COGS = BI + P - EI BI=Beginning inventory P=Purchases for the period EI=Ending inventory If you don't have an actual beginning inventory, you can calculate the beginning inventory as whatever stock is left over from the prior period. The accounting period may be in calendar months, quarters, or years. The COGS is rolling and updated after each transaction in a perpetual system, but you can compute it for a period using the COGS formula. Gross ProfitIn a perpetual system, you could occasionally have to make an educated guess about how much ending inventory there was for a given period. It could be when creating financial statements or if the stock was destroyed. Start with the initial inventory and the cost of the purchases made during the period to determine this estimate. Consider the scenario where you must estimate the ending inventory for the current month. The gross profit as a percentage of sales, the total sales for the period, the initial inventory, and the purchases for the period are the values you need to know to calculate this. Gross Profit = Revenue - COGS It is crucial to be aware of the following:
Keep in mind that whichever inventory method a business decides to go with, it does not affect performance. These methods only have an effect on the way income taxes are reported. For instance, depending on price fluctuations, a company that wants to appear less profitable in an accounting period in order to pay fewer taxes, can decide to opt in for LIFO instead of FIFO.

Advantages and Disadvantages of Perpetual Inventory SystemAdvantages of Perpetual Inventory SystemFor all sizes of e-commerce firms, a perpetual inventory system offers many benefits. It assists in eradicating labor costs and human mistakes in addition to helping in the real-time tracking of inventory data. Let's examine the reasons that e-commerce companies decide to use a permanent inventory system. The following ways represent how perpetual inventory can save you money: Real-time Updates A perpetual inventory system recognizes changes in inventory levels, as soon as a sale or purchase takes place. This constant inventory tracking provides businesses with the advantage of always knowing which goods may be running low so that they can respond on time and avoid stock-outs or shortages. And if you’re managing a big business that operates in several locations and uses several warehouses, a perpetual inventory system allows you to manage everything with ease, through one central automated system. Thorough Paper Trail Available Through your whole e-commerce supply chain, a perpetual inventory system monitors inventory movements. You can uncover strategies to improve your supply chain. It can be done by using this data to gain a deeper understanding of any process bottlenecks. Decreases Inventory Management Costs Inventory replenishments and holding expenses are managed and reduced with real-time data. Labor costs may get reduced with perpetual inventory systems. Perpetual inventory systems automate many manual operations. Year-end Inventory Balance Year-end inventory balance is calculated instantly. It is because a perpetual inventory system continuously accounts for inventory. This makes it easier to ensure that the inventory quantities you disclose for accounting purposes are accurate. Integration with Other Systems The record accuracy it brings to other systems is a crucial benefit of having a perpetual inventory system. For instance, customer care representatives may now provide consumers with precise shipping availability information. The materials management team can plan how many extra units must be manufactured or purchased from suppliers. It can be done by consulting the inventory records. The accounting division may now calculate the ending inventory balance for month-end reporting. Decreased Frequency of Physical Inventory Counts Physical inventory counts no longer need to be performed regularly with a perpetual inventory system, given that every physical count requires a company to halt its warehouse operations for the count period. It is a significant advantage. Additionally, this implies that external auditors are not required to see an inventory count. Instead, they are given an inventory report that contains the locations and unit quantities of the goods, which they may compare to the actual inventory. Precise Demand Forecasts Demand forecasting is made simple with a real-time inventory system. You can analyze historical inventory and sales data to forecast upcoming sales cycles and ensure you have the correct inventory quantity. Planning and Forecasting The perpetual inventory system helps businesses improve their demand forecasts by analyzing the data trends from historical transactions. Businesses can get a better understanding of their customer’s buying patterns, along with insight on best-selling products and growing segments. Save Time and Minimize Error There’s nothing better than automating tedious, repetitive, and time-consuming tasks for you and your employees! A perpetual inventory system saves your business time, money, and prevents a handful of human accounting errors that can occur along the way. Disadvantages of Perpetual Inventory SystemTechnological Dependence: Implementing perpetual inventory systems necessitates a sizable technological infrastructure. This infrastructure comprises both software and hardware tools. It includes warehouse management software, barcode/RFID scanners, and point-of-sale systems. Employee Training: Personnel training is required in terms of time and financial resources. In contrast, manual procedures are often used in periodic inventory systems to count and record your inventory. These procedures can also be used to make adjustments to your inventory ledgers. It can still be the more practical choice for tiny enterprises with modest inventory volumes and tight budgets. Margin-of-Error: Even if computers are less likely to make mistakes than people, it is still conceivable. Especially since some procedures need some human interaction (such as scanning items), physical counts are required to confirm inventory data. It is also due to the propensity for human beings to engage in dishonest behaviors like theft. Periodic inventory techniques and physical inventory checks make more sense for companies that sell high-value, low-volume goods. Such as jewelry shops and auto dealerships. Breakage Of Items: For quick record keeping, inventory levels can be updated using buy and sales data. Any object that is damaged, spoiled, or unsaleable is regarded as a part of the inventory. The perpetual inventory system is at a disadvantage if there isn't an actual physical count to update the broken item's data. Advantages of Periodic Inventory SystemThe periodic inventory approach has several obvious benefits:
Journal Entries for Perpetual InventoryWhen dealing with inventory accounting, you’ll likely find yourself journalizing transactions. Below you’ll find some of the most common journal entries you’ll need, to do accounting for your inventory. 1. Purchase of Merchandise at CostTo record the purchase of merchandise at cost, inventory is debited and accounts payable credited, as shown below: 2. Payment of APThe journal entry for making an invoice payment would look like this: 3. Credit TermsTypically, manufacturers and wholesalers will sell goods on credit. These credit terms are written down in the seller’s bill or invoice. For the sake of our example, let’s assume that on April 1st, the company purchases another $2,000 worth of merchandise, on credit, with payment terms 2/10 net 30. A 2/10 net 30 payment term means that the buyer has 30 days to pay back its vendor, but can get a 2% discount if they pay within 10 days. Now, Company XYZ records their purchases at net cost, which is the invoice price of $2,000 minus the 2% available discount, which amounts to $40. Therefore, the company will record this purchase as follows: If the company fails to pay within 30 days, and losses the discount, the following journal entry will be made to record the loss: 4. Sale of MerchandiseWhen a business sells merchandise, two journal entries need to be created: one to recognize the sale, and another to record the costs of goods sold. 5. Collection of ARCash collection of accounts receivable is recorded as shown below: Want to learn more about the different types of accounts and how to properly journalize them?
