This document discusses technology used in the hotel and restaurant industries. It begins by explaining how property management systems (PMS) emerged to handle core functions for hotels like reservations, front office/back office operations, and management. PMS provides benefits such as improved efficiency, inventory control, and marketing/sales reports. It then discusses how restaurants divide technology between back-of-house systems for inventory, ordering, and labor management, and front-of-house point-of-sale systems.
