LIFO (last-in-first-out) and FIFO (first-in-first-out) are two different strategies for storing and retrieving goods.

What is Last-in-first-out?

The last-in-first-out principle describes a storage strategy in which the goods that were put into storage last are the first to leave the warehouse again. Storage techniques that use the LIFO principle include the following:

• Satellite rack storage
• Row storage
• Drive-in rack storage

what is First-in-first-out?

The first-in-first-out principle describes a storage strategy in which the goods  that were put into storage first are also the first to leave the warehouse. Storage techniques that use the FIFO principle include the following:

• Pallet flow rack warehouse
• Container flow rack warehouse

In storage types, such as high-bay warehouses, the application of the method depends, among other things, on the storage technology used.
