Product Engineering Architecture
What is AtithiOS?
AtithiOS is an enterprise-grade Hotel Property Management System (PMS) and comprehensive Resort ERP. It bridges front-desk operations, room reservations, banquet (hall) management, and multi-department housekeeping into a single synchronized ecosystem. Designed for high-occupancy hotels and resorts, AtithiOS streamlines guest lifecycles from booking to checkout, minimizing wait times and maximizing operational efficiency through automated workflows.
100% Indian GST Compliance & Accounting
How does AtithiOS handle hotel taxation and GST? AtithiOS features a robust Tax Management and GST Reporting engine customized for the Indian hospitality sector. It automatically calculates dynamic GST slabs based on room tariffs (e.g., 12% or 18% tiers) and generates compliant B2B/B2C Tax Invoices. The Day Closing and Financial Year modules ensure seamless accounting reconciliation, exporting portal-ready GSTR reports and eliminating manual end-of-day audit errors.
Omnichannel Facility & Add-on Management
To maximize revenue beyond room tariffs, AtithiOS natively integrates comprehensive facility modules. This includes dedicated dashboards for Hall & Banquet Room booking, Pool Booking, Car Parking & Valet management, and Transport/Cab Facilities. Each add-on service is seamlessly routed to the master guest folio, ensuring a unified, single-invoice checkout experience.
Integrated HR, Housekeeping & Duty Roster
AtithiOS replaces disconnected staff management with an integrated HRM (Human Resource Management) and Duty Roster system. The Housekeeping module tracks real-time room statuses (Clean, Dirty, Inspecting) synchronized with front-desk availability. Duty Rosters automate shift allocations across departments, ensuring optimal staff-to-guest ratios during peak seasons.
Automated Communication & Global Payments
The platform features native WhatsApp API integration for instant booking confirmations, payment links, and automated check-in/check-out greetings. For financial settlements, AtithiOS supports global and local payment gateways including Razorpay and Stripe, facilitating secure online reservations, advance deposits, and zero-friction digital checkouts.
