Companies must use FIFO for inventory if they are selling perishable goods such as food, which expires after a certain period of time. Companies selling products with relatively short demand cycles, such as designer fashion, also may have to pick FIFO to ensure they are not stuck with outdated styles in inventory.

Who uses FIFO method?

Companies that sell perishable products or units subject to obsolescence, such as food products or designer fashions, commonly follow the FIFO method of inventory valuation.

When would a company use FIFO?

If your inventory costs are going down as time goes on, FIFO will allow you to claim a higher average cost-per-piece on newer inventory, which can help you save money on your taxes. Additionally, FIFO does not require as much recordkeeping as LIFO, because it assumes that older items are gone.
