Payments
Hotel payments built in — from deposit to final bill, on one guest bill, with tax worked out for you.
The problem with the fragmented stack
You take a deposit on one system, charge the room on another, refund the wrong card — and month-end never reconciles.
What you get
One bill for everything a guest spends
Room, restaurant, spa and more on a single bill, with one clean invoice even across several of your hotels.
Tax worked out for you
The right VAT and service charge on every line, automatically.
Card details never on your systems
Stored safely off-site, so there’s nothing on a desk or in an inbox to be stolen.
Ona collects what’s owed
She works out the exact balance and sends the guest a link to pay. She never charges a card herself — a line she cannot cross.
Deposits and refunds on autopilot
Holds released before they expire, the right amount refunded on a penalty cancel.
Straight into your accounts
A daily journal into your accounting system.
One merchant account for the group
Collect under your own brand across every property.
Why it wins
Money and the booking live in the same place, so they always agree — not a separate terminal and login.
Tax and VAT auto-calculated per line, with a finance stack most global vendors don’t offer.
Ona pay-by-link that knows exactly what’s owed — and never charges itself.
