Xero Validation Error: Credit Note not of valid status for modification
Applies to: ConnectWise, Xero
How can this happen?
A credit note is either $0 or has already been applied to an invoice in Xero.
Solution

- Delete the allocated credit
- Re-sync the credit note
- Then make sure to apply the credit note both in Xero and ConnectWise.
