Companies that use periodic accounting do all necessary journal entries and bookkeeping at the end of each accounting period. As part of their period-ending work, they count inventory and then use that number on the balance sheet and to calculate cost of goods sold. Traditional or manual inventory systems, where inventory activities are managed manually and information is stored on paper, are sometimes referred to as physical inventory systems. However, this term is not entirely accurate, as it implies that these systems directly reflect the physical inventory at hand.

The periodic system accounts for the COGS with a single transaction after a physical inventory count. There are various shortcomings of this system as the amount of the cost of goods sold may include the goods lost or theft during the year. However, with the help of sales revenue, an estimation could be made regarding the lost inventory but this figure is not accurate. If the physical valuation of the stock is done more than once in a year, then this system can also cost higher. Discrepancies can be detected only at the end of the accounting period. Under a perpetual inventory system, you get all purchase and production data, your sales data, and the unsold items with quantities.
At the end of the period, a perpetual inventory system will have the Merchandise Inventory account up-to-date; the only thing left to do is to compare a physical count of inventory to what is on the books. A physical inventory count requires companies to do a manual “stock-check” of inventory to make sure what they have recorded on the books matches what they physically have in stock. Differences could occur due to mismanagement, shrinkage, damage, or outdated merchandise. Shrinkage is a term used when inventory or other assets disappear without an identifiable reason, such as theft. For a perpetual inventory system, the adjusting entry to show this difference follows.
What is a Periodic Inventory System?
A periodic inventory system updates and records the inventory account at certain, scheduled times at the end of an operating cycle. The update and recognition could occur at the end of the month, quarter, and year. There is a gap between the sale or purchase of inventory and when the inventory activity is recognized. These discrepancies highlight the limitations of relying solely on a periodic inventory system for accurate inventory tracking. Tracking inventory effectively requires awareness of what you have on hand (inventory balance) and the cost of goods sold (COGS).
Second, perpetual inventory systems are often more expensive than periodic systems. Like we said, it’s pretty much nuts to try to run a perpetual system by hand—meaning you’ll likely have to pay for an inventory management software. And if you opt to simplify the process further with RFID tags or barcodes, you’ll also need to invest in extra equipment (like scanners) and training to help your employees use your system correctly. https://intuit-payroll.org/ The trouble with periodic systems, though, is that they don’t track inventory on an item-by-item or transaction-by-transaction basis. For starters, that makes it hard to identify accounting errors when they occur, and you can’t track product movement with as much accuracy as you could with a perpetual inventory system. But most importantly, periodic systems make it harder to accurately calculate your cost of goods sold (COGS).
The periodic inventory system also allows companies to determine the cost of goods sold. “The terms ‘periodic inventory system’ and ‘physical inventory’ are often used interchangeably, but they have distinct meanings. Physical inventory refers to the actual quantity of goods on hand at a given time, typically determined through a physical count. A purchase return or allowance under perpetual inventory systems
updates Merchandise Inventory for any decreased cost. Under
periodic inventory systems, a temporary account, Purchase Returns
and Allowances, is updated. Purchase Returns and Allowances is a
contra account and is used to reduce Purchases.
Definition of Perpetual Inventory System
But choosing between a perpetual inventory system and a periodic inventory system is about much more than cost. Periodic inventory is normally used by small companies that don’t necessarily have the manpower to conduct regular inventory counts. These companies often don’t need accounting software to do the counts, which means inventory is counted by hand. As such, the system is commonly used by companies that sell small quantities of inventory, including art and auto dealers. There are two ways in which a company may account for their
inventory.
Perpetual inventory method:
Retailers that use the perpetual system often make it a practice to count inventory (or at least a sample of inventory) to make adjustments for shrinkage. It also wouldn’t make sense for small businesses that sell their inventory as a side project to use perpetual inventory. An appliance repair company selling two or three used refrigerators per month has no need to invest in an expensive point-of-sale system. As a child, one of my favorite days of the year was when I would go to work with my dad on a Saturday to count inventory.
A physical inventory count requires
companies to do a manual “stock-check” of inventory to make sure
what they have recorded on the books matches what they physically
have in stock. Differences could occur due to mismanagement,
shrinkage, damage, or outdated merchandise. Shrinkage is a term
used when inventory or other assets disappear without an

That’s because it takes the inventory at the beginning of the reporting period and at the end unlike the perpetual system, which takes regular inventory counts. So if there is any theft, damage, or unknown causes of loss, it isn’t automatically evident. The periodic inventory system is commonly used by businesses that sell a small quantity of goods during an accounting period. These companies often find it beneficial to use this system because it is easy to implement and because it is cost-effective, as it doesn’t require any fancy software.
The perpetual inventory system is expensive because you need different types of technical equipment and trained employees. Additionally, it is possible to include the cost of direct labor and manufacturing overhead (aka factory burden) in the cost of the finished goods via the WIP account. From small teams to large enterprise teams have found our asset management solution extremely useful for asset tracking, maintenance and streamlining define the income summary account. their entire asset life cycle.

This example assumes that the merchandise inventory is overstated in the accounting records and needs to be adjusted downward to reflect the actual value on hand. A physical inventory count requires companies to do a manual “stock-check” of inventory to make sure what they have recorded on the books matches what they physically have in stock. Shrinkage is a term used when inventory or other assets disappear without an identifiable reason, such as theft. At the end of the period, a perpetual inventory system will have
the Merchandise Inventory account up-to-date; the only thing left
to do is to compare a physical count of inventory to what is on the
books.
And even though implementing one does require a united effort, it is nowhere near as time and resource-consuming as it was ten years ago. Furthermore, in a periodic inventory system, purchases are
recorded in a separate purchases account from where information passes on to
the inventory balance only at the end of the accounting period. A periodic inventory system is a bookkeeping method based on counting and marking down your items. It means updating the inventory balance periodically, at the beginning and at the end of an accounting period. Smaller enterprises, often constrained by budgetary limitations and lacking the resources for sophisticated computerized systems, frequently opt for the periodic inventory system. This approach involves intermittent physical counts to assess both inventory levels and the cost of goods sold (COGS).
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. When manufacturing is finished, the final cost of the
finished products is moved from the work in progress account to a finished
goods inventory account. Once the purchased goods are received, their value is transferred from the purchases account to a corresponding inventory account. If inventory is central to your business, it must be managed, and to do that it, must be measured. Businesses that account for inventory periodically likely use the FIFO method to sell older units first.
The primary case where a periodic system might make sense is when the amount of inventory is very small, and where you can visually review it without any particular need for more detailed inventory records. First, it can be a heavy lift for businesses trying to do their inventory tracking manually. With a perpetual inventory management system, you can pinpoint an exact cost of goods sold for each item you sell—getting a clearer picture of where your business stands. The purchases account is closed at the end of the period with a closing journal entry that moves the balance into inventory. In the periodic section, we used a separate purchases account to track new inventory coming during the period, and then we used that account in a formula to calculate cost of goods sold.
