The process is not fully automated. You will need to export the invoices from the SBPay.me Invoices page and import them on the Xero side.
(we have prepared the specific file format to make it easy)
If standard Xero import functionality is used, invoices will be imported as Draft. For invoices to be Approved or Paid, Xero Conversion Toolbox should be used.
Tax amount is not exported since Xero imports final amounts as tax exclusive. Taxes are calculated and added to the final amounts within the Xero platform itself.
Xero Custom Feature will work only if the Invoices custom feature is enabled in the SBPay.me
