How can I fix invoice not of valid status for modification?

Cause:

This error occurs when attempting to sync an invoice that is already paid inside Xero. Xero restricts modifications to invoices that are not yet paid.

Resolution:

To resolve this issue, you have two options:

1. Ignore the Sync: If the invoice modification is not necessary or does not need to be reflected accurately in Peakflo, you can choose to ignore the sync error. 

2. Undo Xero Changes: You can undo the changes made to the invoice in Xero to reverse the payment status. Once the changes are reversed, Peakflo can sync the data accurately.
