Perpetual FIFO, LIFO, Average

This and other unethical short-term accounting decisions made by Petersen and Knapp led to the bankruptcy of the company they were supposed to oversee and resulted in fraud charges from the SEC. Practicing ethical short-term decision making may have prevented both scenarios. Companies can choose among several methods to account for the cost of inventory held for sale, but the total inventory cost expensed is the same using any method. The difference between the methods is the timing of when the inventory cost is recognized, and the cost of inventory sold is posted to the cost of sales expense account. Perpetual inventory systems track sales constantly and immediately with computerized point-of-sale technology. Periodic inventory systems only track sales when a physical count is ordered and require a point-in-time count.

  1. 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.

  3. Weighted average cost is an accounting system that uses a weighted average to determine the amount of money that goes into COGS and inventory.
  4. The calculated inventory levels derived by a perpetual inventory system may gradually diverge from actual inventory levels, due to unrecorded transactions or theft.

In 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.

Sale Transactions

At all other times, the inventory records under a periodic inventory system will not reflect the amount of inventory that is actually on hand. Despite their inherent inaccuracy, periodic inventory systems can be useful in situations where the inventory value is low and a company does not have much of it. In these situations, a simple manual scan of the inventory may be sufficient to verify whether there is any inventory on hand. Clearly, periodic inventory systems are used by quite small businesses that operate with relatively primitive paper-based systems.

Here, we’ll briefly discuss these additional closing entries and adjustments as they relate to the perpetual inventory system. The specific identification costing assumption tracks inventory items individually so that, when they are sold, the exact cost of the item is used to offset the revenue from the sale. The cost of goods sold, inventory, and gross margin shown in Figure 10.13 were determined from the previously-stated data, particular to specific identification costing. Petersen and Knapp allegedly participated in channel stuffing, which is the process of recognizing and recording revenue in a current period that actually will be legally earned in one or more future fiscal periods.

The last transaction was an additional purchase of 210 units for $33 per unit. Ending inventory was made up of 30 units at $21 each, 45 units at $27 each, and 210 units at $33 each, for a total LIFO perpetual ending inventory value of $8,775. The first-in, first-out method (FIFO) of cost allocation assumes that the earliest units purchased are also the first units sold.

Normally, no significant adjustments are needed at the end of the period (before financial statements are prepared) since the inventory balance is maintained to continually parallel actual counts. Within this system, a company makes no effort to keep detailed inventory records of products on hand; instead, purchases of goods are recorded as a debit to the inventory database. A perpetual inventory system differs from a periodic inventory system, a method in which a company maintains records of its inventory by regularly scheduled physical counts.

This is why many companies perform a physical count only once a quarter or even once a year. For companies under a periodic system, this means that the inventory account and cost of goods sold figures are not necessarily very fresh or accurate. A periodic inventory system is kept up to date by a physical count of goods on hand at specific intervals to calculate COGS using inventory valuation methods such as FIFO, LIFO, and weighted averages. With a periodic inventory system, retailers calculate current inventory counts at the end of an accounting period or financial year and only then report on it. This purchase transaction triggers another journal entry, this time only on your balance sheet. In this example, a total of $1,500 (500 units x $3.00 each) should be recorded as a debit to inventory, and a credit to either accounts payable or cash.

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. 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.

The perpetual inventory system gives real-time updates and keeps a constant flow of inventory information available for decision-makers. With advancements in point-of-sale technologies, inventory is updated automatically and transferred into the company’s accounting system. This allows managers to make decisions as it relates to inventory purchases, stocking, and sales. The information can be more robust, with exact purchase costs, sales prices, and dates known.

Head over to our guide on journalizing transactions, with definitions and examples for business. 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. 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.

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. In a periodic inventory system, a purchase account is opened, whereas in a perpetual inventory system, depending on the nature of the transactions, either a raw materials account or merchandising account is maintained. There are key differences between perpetual inventory systems and periodic inventory systems. The data shown in the record relate to the journal entries given above.

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. The perpetual inventory system keeps track of inventory balances continuously. This is done through computerized systems using point-of-sale (POS) and enterprise asset management technology that record inventory purchases and sales. It is far more sophisticated than the periodic system of inventory management.

Also, as already noted, some perpetual records maintain only a record of units. The balance in the Merchandise Inventory account is then adjusted to the actual ending inventory, as determined by the physical count. Correct journal entries for the perpetual inventory system are shown below. The downside of this is that the perpetual inventory management system is relatively difficult and more expensive to set up since you’d require investment in inventory software, computers and expertise. Not only must an adjustment to Merchandise Inventory occur at the end of a period, but closure of temporary merchandising accounts to prepare them for the next period is required.

Any manual entry greatly increases the risk of data entry errors, which reduces the accuracy of the inventory records. For example, a retail store may sell thousands of items per day, each of which must be recorded as a reduction in the on-hand quantity. Without bar code labels or RFID tags, it is quite likely that these sales would be charged to the wrong units, or in the wrong quantities, or not recorded at all.

Although a periodic physical count of inventory is still required, a perpetual inventory system may reduce the number of times physical counts are needed. The perpetual inventory system is a more robust system than the periodic inventory system, which is where a company undertakes  regular audits of stock to update inventory information. These audits include regular physical inventory counts on a scheduled and periodic basis. The major difference between perpetual and periodic inventory systems is that the former has a system that updates inventory information in real-time while the latter uses a more manual process.
