Correcting an Invoice
You can correct an invoice that you have not posted. Modify pricing and covered amount in Call Invoice Recording when you review the invoice. Change inventory amounts or add labor in CAR.
To make changes to a closed call, change the call’s status in Call Activity Recording. If the line you want to change is closed, reopen it. Then you can modify or add a report. The system regenerates invoice amounts only for changed call lines.
After you post the invoice, the status of all reports included on the invoice is closed. You can view, but not modify, these reports.
