LIFO stands for Last-In-First-Out. It is a method used for inventory management in which the items that are last to be received are the first to be used or sold. Synonyms for LIFO include reverse chronological order, last come first served, and newest first out. These synonyms describe the same process of using the most recent items before the older ones in a given set of inventory. This technique can be applied in various industries, including retail, manufacturing, and agriculture, to ensure efficient use of resources. Practicing LIFO can help organizations reduce waste, manage inventory levels, and improve product turnover.
