  • It can be done by using this data to gain a deeper understanding of any process bottlenecks.
  • The last in, first out (LIFO) method means you sell your newest purchased or manufactured goods first.

Businesses increasingly track inventory using a perpetual inventory system versus the older, physical-count periodic inventory system. Perpetual systems are costly to implement but less expensive and time-consuming over the long haul. 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. Proponents of perpetual inventory systems don’t always go out of their way to point out the downsides of these systems, the chief of which is the lack of accounting for loss, breakage, or theft.

The perpetual inventory system involves the continuous updating of inventory records.

A perpetual inventory system requires software to continuously track thousands of records in real-time. 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.

Accountants don’t have to constantly adjust the changes in inventory levels since everything is done by the computing system (for the most part). For example, optical scanners are used in markets to keep track of inventory quantities, but at the end of the accounting period, a physical inventory is performed. However, even with such sophisticated equipment, perpetual records may be kept only in units, with the cost of ending inventories and goods sold determined by the periodic inventory system.
