How to fix Xero error "Invoice not of valid status for modification"

Is your bill stuck in "Sync in Progress" status for a long time? It could be because there's an error in your accounting software that delays the data sync in Peakflo. 

As a result, the bill in sync progress can't be moved to draft.

Worry not, let's see how we can fix this problem. 


This error appears when the user is syncing an invoice that is already paid in Xero.


  1. In Xero, remove the payment associated with the bill.
  2. In Peakflo, go to the Accounting section and under Transactions, find the bill with this error (you can sort by dates to navigate easier). Then, re-sync the bill.
