Last in First Out (LIFO) is a cost flow assumption technique that assumes the inventory movement to be in a manner that the latest purchased products are sold first. Similar to FIFO periodic inventory system, in LIFO as well, the calculation begins with a physical count of inventory. The company makes a physical count at the end of each accounting period to find the number of units in ending inventory. The company then applies a first-in, first-out (FIFO) method to compute the cost of ending inventory.

In perpetual inventory systems, computer programs and software are typically used to record and report transactions as soon as they take place.

The Cost of Goods Sold (COGS)

When there is a loss, theft or breakage, you should also immediately record these updates.

run. When a purchase is placed to a vendor and you receive the
invoice, it is recorded in an asset account, showing the sum of purchased goods

What is the difference between periodic and perpetual inventory?

If you use a periodic system, you don’t know the exact number of units you have in stock until the end of the accounting period when you do your physical count of inventory. In contrast, the perpetual inventory system gives you real-time inventory counts because it updates each time a unit moves in or out of your inventory. LIFO means last-in, first-out, and refers to the value that businesses assign to stock when the last items they put into inventory are the first ones sold. The products in the ending inventory are either leftover from the beginning inventory or those the company purchased earlier in the period.

However, with a perpetual system, you need to make more decisions to use it successfully. Periodic inventory is a system of inventory valuation where the business’s inventory and cost of goods sold (COGS) are not updated in the accounting records after each sale and/or inventory purchase. Instead, the income statement is updated after a designated accounting period has passed.
