Every plan gets invoices, payments and contacts out of Onyx One and into Xero without re-keying. Pro plans also connect their Xero organisation directly.
The one-time mapping
In Settings, under Xero, set your sales account code (the New Zealand default is 200) and the exact GST tax-rate names your Xero organisation uses, such as 15% GST on Income and Zero Rated. Leave a field blank to use the NZ default. Xero rejects imports whose names do not match, which is why this lives in settings instead of your memory.
The export, on every plan
Invoices, payments and contacts leave as CSV files shaped for Xero's importer, with GST at 15% already computed. Your accountant imports them directly.
The connection, on Pro
Pro and Enterprise plans click Connect to Xero, approve access on Xero's own sign-in page, and can disconnect at any time. The grant is encrypted at rest, and only owners and admins can touch it. Two-way sync over Xero's API is in build and lands for connected organisations as it ships.
