O.S.S Smart Management Platform is browser-based software for hotels, restaurants, and operations teams. Hotels manage reservations, front desk, housekeeping, maintenance, guests, folios, and operational reports. Restaurants use QR ordering with waiter confirmation, kitchen display, cashier workflows, menus, tables, staff roles, and supported inventory features. Operations teams manage clients, projects, tasks, inventory, quotes, invoices, and operational finance. O.S.S runs in the cloud through a web browser on desktop, tablet, and phone. A 14-day trial is available with no credit card required at signup. O.S.S is provided by Orange Studio MMC, Baku, Azerbaijan.
