Last In / First Out (LIFO) is an inventory management method where the most recently received stock is used or sold first. In logistics and accounting, LIFO is used to manage inventory costs, particularly for products with fluctuating prices. While LIFO can reduce tax liability in some regions, it requires careful tracking to prevent older inventory from becoming obsolete or expired. LIFO is commonly used in industries where products are non-perishable or where stock rotation is not critical.
