What is a Periodic Inventory System + When to Use it

Periodic inventory systems don’t continuously update inventory accounts to reflect individual sales. Instead, you manually edit these values at the end of your specified time interval. Because of this, the method requires keeping personal accounts for beginning inventory, purchases and on-hand inventory. Notice that there is no particular need to divide the inventory account into a variety of subsets, such as raw materials, work-in-process, or finished goods.

In a periodic system, all transactions conducted are listed in a purchase account for the company, which monitors inventory based on deduction of the cost of goods sold (COGS). It doesn’t, however, account for broken, damaged, or lost goods and also doesn’t typically reflect returned items. It is why physical inventories are necessary, to accurately reflect how many tangible goods are in a store or storage area.

Smaller businesses and those with low sales volumes may be better off using the periodic system.
