Last-in, first-out LIFO method in a periodic inventory system
When a physical inventory count is done, the balance in the purchases account is then shifted into the inventory account, which in turn is adjusted to match the cost of the ending inventory. The periodic inventory system refers to conducting a physical inventory count of goods/products on a scheduled basis. Maintaining physical inventories can be costly because the process eats up time and manpower.
The only time the inventory account is updated is at the end of the year, creating the need for estimating inventory amounts. In contrast, a perpetual inventory system updates the inventory account every time inventory is purchased or sold, without the use of a Purchases account. A periodic inventory system relies on a physical count of your on-hand inventory to calculate current inventory and COGS at the end of your accounting period.

It is also a method used by companies to calculate the cost of goods sold (COGS) during a specific allotment of time. Careful evaluation of business needs and resources is essential to make an informed decision on the most appropriate inventory management system. In a periodic inventory system, you use regularly scheduled physical inventory counts to measure the cost of goods sold and see how much product you have available.
- Some small businesses may also choose the periodic system because of its affordability.
- Companies track shipping costs related to inventory due in Cash on Delivery and Cash on Due.

- JIT inventory reduces your storage and insurance costs and the expense of holding, liquidating, or discarding excess inventory.
When merchandise is sold, an entry is made to record the sales revenue, but none to record the cost of goods sold, or to reduce the inventory. That’s why businesses with high sales volume and multiple sales channels use a perpetual inventory system, instead. Record the purchase returns by debiting the accounts payable or accounts receivable account and crediting the purchase returns account.
You might want to consider ecommerce accounting software and automated methods, such as the perpetual inventory system, if your business is growing fast. 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. This is why many companies perform a physical count only once a quarter or even once a year.
Periodic inventory management vs. perpetual inventory management
A small company with a low number of SKUs would use a periodic system when they aren’t concerned about scaling their business over time. Depending on your products and needs, you could also use a periodic system in concert with a perpetual system. The term inventory refers to the raw materials or finished goods that companies have on hand and available for sale. Inventory is commonly held by a business during the normal course of business. It is among the most valuable assets that a company has because it is one of the primary sources of revenue. Small businesses with fewer Stock Keeping Units (SKUs) use a regular system when they don’t want to grow their business over time.
Great option for small business
Because there’s no constant inventory tracking, it can be difficult for a firm to be aware of which goods are running low on stock, or if there’s an excess supply for a type of inventory. When merchandise is purchased, the cost is not debited to the Inventory account, but rather to another account called Purchases. Under a periodic inventory system, any change in inventory is recorded periodically, typically at the end of the month or year. A company’s COGS vary dramatically with inventory levels, as it is often cheaper to buy in bulk, especially if it has the storage space to accommodate the stock. As a result, they can quickly count the goods they work with, while the ongoing system, which provides a more accurate inventory, requires staff training in electronic scanners and data entry.
Alternatives to a periodic inventory system
A periodic inventory system is a form of inventory valuation where the inventory account is updated at the end of an accounting period rather than after every sale and purchase. On the other hand, in a periodic inventory system, inventory reports and the cost of goods sold aren’t kept daily, but periodically, usually at the end of the year. A periodic inventory system also requires manual data entry and physical inventory counting. So, every time a product is purchased or sold, the perpetual system uses a barcode scanner to update the inventory count, and recalculate the corresponding cost of goods sold. Then, whenever inventory levels hit a reorder point, the software automatically generates the purchase orders necessary for restocking.
It is both easier to implement and cost-effective by companies that use it, which are usually small businesses. The perpetual system is generally more effective than the periodic inventory system. That’s because the computer software companies use makes it a hands-off process that requires little to no effort. Products are barcoded and point-of-sale technology tracks these products from shelf to sale. These barcodes give companies all the information they need about specific products, including how long they sat on shelves before they were purchased. Perpetual systems also keep accurate records about the cost of goods sold and purchases.
In a perpetual LIFO system, the company also uses the running ledger tally for purchases and sales, but they sell the inventory that they last purchased before moving to older inventory. In other words, the cost of what they sell is the same as what they most recently paid for that inventory. You can also use a periodic system if you have a handle on your supply chain process, sell a few products and have eyes on your goods as they flow through your business. A periodic system isn’t useful if you need to investigate to identify missing inventory or unbalanced numbers. This issue will arise as your operation grows and becomes more challenging to control positively. Small firms may believe that implementing a perpetual inventory system will necessitate the purchase of inventory management software, IT infrastructure, and other specialist equipment.
Record the purchase of inventory in a journal entry by debiting the purchase account and crediting accounts payable. The guide has everything you need to understand and use a periodic inventory system. You’ll find basic journal entries, formulas, sample problems, guidance, expert advice and helpful visuals.
A perpetual system can scale, so whether you have five products (today) or 200 products (tomorrow), a perpetual system can effectively manage inventory control. The main benefits of employing a periodic inventory system are the ease of implementation, its lower cost and the decrease in staffing needed to run it. Simple counts on legal types of liabilities paper can suffice for collecting product data, especially if you only offer a few goods. A basic count during the day or week is often enough for a small business to get an adequate handle on their inventory. This means there is no need for expensive or complicated equipment, just essential information collection tools – pen and paper.
It’s also far simpler to estimate the cost of goods sold over designated periods of time. This is because your accounting records are only modified at the end of your year, or the end of a preestablished accounting period, to reflect your physical inventory count. A periodic inventory system is a method of accounting for inventory in which stock updates are made periodically. Periodic inventory systems require you to physically count inventory to determine your on-hand stock levels and the cost of goods sold (COGS). As such, they use occasional physical counts to measure their inventory and the cost of goods sold (COGS).
