The document discusses inventory control methods for food and beverage companies, specifically FIFO (first in, first out) and FEFO (first expired, first out). It explains that FEFO prioritizes products with the shortest shelf life to be distributed first to reduce spoilage, while FIFO ensures the oldest products in inventory are shipped out first. The document also notes that software like SAP Business One can help companies comply with regulations through features like tracking expiration dates and automatically implementing FEFO and FIFO.
