01 · Why Xero
Why merchants choose Wonderful
Connect the One app to Xero, sync your contacts overnight, and let every payment auto-generate and reconcile the right invoice — with zero card fees.
Xero contacts in One
An overnight job syncs all your Xero contacts straight into the One app – so the right customers are always at your fingertips when you create a payment.
Invoices that mark themselves paid
Every payment in One creates a draft invoice in Xero, with the right revenue account and tax rate applied. When the customer pays, the invoice is marked as paid automatically.
Zero card fees on every payment
No percentage-based processing fees, ever. Your Xero books stay clean of card charges – just the flat subscription and your payment receipts.

Simple pricing that makes sense
The Xero integration is included on both our Plus and Pro plans.
Plus Plan — £48.00 / month + VAT
