First checks
- Confirm Xero is connected for the tenant.
- Reconnect Xero if the token has expired or the selected Xero tenant is wrong.
- Check the customer contact and invoice email details.
- Check VAT or tax mapping before sending invoices.
- Check whether the order has final picked quantities and final weights.
Information needed for support
Send tenant, customer, order number, invoice number if created, Xero contact, timestamp, and the exact error message shown in Porosi.
Do not do this
Do not manually change live production data until the failed sync has been understood. Test the workflow on the Porosi demo tenant when reproducing a setup issue.
