In order to get Invoices back into Innovent Integration S/W-

1. In ConnectWise, under Finance -> Accounting Interface -> Open Batches

2. Select the batch with the invoices that you want to revert (Name format - YYYYMMDDhourminsec) 

3. Actions tab -> DELETE BATCHES option and NOT close batches


This would get all the invoices sent to Xero in that batch and display them again in CW and Xero Integration S/W.
