What hoteliers ask us.

Hotel management software that runs your whole hotel as one system, on a single shared guest record: bookings, front desk, restaurant, spa, payments, guests and marketing. Nothing is typed twice, and every number agrees.

A PMS with integrations is still separate systems passing copies to each other, and copies drift. ONEOS is one system with one source of truth, so there’s nothing to integrate and nothing to reconcile. The answer isn’t better integrations. It’s not needing them.

Yes. ONEOS replaces most of the stack, and the Marketplace connects the few tools you want to keep, switched on without a developer.

Yes. Every property runs on the same system, so a guest has one profile across the whole group, segments work group-wide, and your numbers roll up without a spreadsheet. Groups agree a go-live date in their contract.

Yes. Pricing starts from 10 rooms, core already covers the whole hotel, and you switch on only the modules you need. Independent and boutique hotels up to 50 rooms can be live in as little as 14 days.

Ona is the AI built into ONEOS, not bolted on. She runs through every module: pricing your rooms, briefing your front desk, answering your data in plain words, and talking to your guests. She recommends and you approve, always with her reasoning shown.

No. Ona and the machine-learning models beneath her are part of the platform itself. They run on the same data lake as every module and learn from your property’s own history. Your data is never used to train models for other hotels, or by our AI providers.

Only if you let her. Autopilot is yours to give, lever by lever, and every action she takes is logged and can be undone. She never charges a card herself. She works out the balance and sends a pay link.

One fee per room, per month, for the system, plus the modules you switch on. No setup charge and nothing metered. Use the pricing calculator to see your number and what it replaces. Prices are set in US dollars, and you can be billed in your own currency. Monthly, with an optional annual discount.

No. Core runs the whole hotel: PMS, Operations, RMS, Booking Engine, B2B & Corporate, CDP & CRM, Communications, Commerce, Upselling, the Guest and Staff Apps, AI Concierge and Payments. The other seven modules switch on one at a time, at around a dollar a room and below, each.

No. ONEOS is monthly by default, with an optional annual discount. There’s no long lock-in to get the headline price, and the number the calculator shows is the price.

As little as 14 days for up to 50 rooms, 30 days for larger single properties, and a date agreed in the contract for groups. If a single property isn’t live within 30 days, its first month is on us.

Nothing. We migrate your guests, bookings, rates, rooms and history for you, with no professional-services invoice. It takes about six hours of your team’s time, not six weeks.

A named onboarding lead takes you through go-live, with a free online academy and live sessions so your team is confident before the first guest checks in. We check in on day 2, day 7 and day 30.

A real person on every plan, with no premium support tier, during business hours (8am–6pm, Monday to Saturday, Bangkok time), plus an AI assistant around the clock. Reach us by chat, email, phone, LINE or WhatsApp.

We’re built for Asia-Pacific first, and the platform and the guest-facing surfaces are multilingual, so your guests are served in their own language.
