Designed to meet the varied requirements of any size hotel or hotel chain, OPERA PMS provides all the tools a hotel staff needs for doing their day-to-day jobs — handling reservations, checking guests in and out, assigning rooms and managing room inventory, accommodating in-house guest needs, and handling accounting and billing. The property management software is configurable to each property’s specific requirements and operates in either single-property or multi-property mode, with all properties in a complex sharing a single database.
