Who it’s for · Asia-Pacific
Built in Asia-Pacific, for hotels in Asia-Pacific.
Headquartered in Bangkok and hosted in Singapore, ONEOS handles the taxes, currencies, languages and messaging apps that hotels across the region deal with every day.
Local by design
The local detail is built in, not bolted on.
Service charge before VAT, a guest who messages on LINE or WhatsApp, a group paying in baht and a travel agent paying in dollars. In the region, that’s an ordinary Tuesday.
Local taxes, in the right order
VAT, service charge and local levies calculated in sequence, including tax on service charge, and posted as separate lines on every folio.
Tax invoices from the folio
Numbered, gap-free tax invoices issued straight from the guest bill, ready for your accountant.
Your guests’ currency
Prices shown in eight currencies at live rates, with billing in the currency you agree with us.
Your guests’ language
Guest-facing pages and messages in the languages your guests speak, and Ona understands them all.
The apps guests already use
Guest messages on LINE, WhatsApp, SMS and email land in one inbox, with the booking alongside.
Your data stays in the region
Hosted in Singapore, with encrypted transport end to end and nothing shared between hotels.
Close by
