The first in, first out (FIFO) method assumes that the oldest units are sold first, while the last in, first out (LIFO) method records the newest units as those sold first. Businesses can simplify the inventory costing process by using a weighted average cost, or the total inventory cost divided by the number of units in inventory.

But, you could manually track transactions in a periodic inventory system, as it only needs updating every period. The LIFO (last-in, first-out) perpetual inventory method is the opposite of FIFO and makes a cost flow assumption that the last items received in inventory are the first items sold. So, the inventory remaining at the end of the period is the oldest purchased or produced. The FIFO (first-in, first-out) perpetual inventory method makes a cost flow assumption that the first items received in inventory are the first items sold.
