Why is my Xero invoice failing to create when a contact has multiple email addresses?

If you’re using Xero and have entered multiple email addresses for a contact (separated by commas), you may see an error like:

“Failed to create contact in Xero: Email address must be valid.”

Why this happens

SortScape allows multiple email addresses per contact (comma-separated).

However, Xero only supports a single email address per contact.

When you create an invoice in SortScape with Xero connected:

1. SortScape first attempts to create or sync the contact in Xero
2. If the contact has multiple email addresses, Xero rejects it
3. Because the contact fails to create, the invoice is never created in Xero This is a known limitation in Xero:
