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


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.


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. 

Please note this may result in data inconsistencies between Xero and Peakflo.

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.
