Should you need to change certain things in an invoice after it has been finalized, WorkBook offers the possibility.
Needless to say, this should only be done in very few cases.
Two System variables
Two System variables control what you may edit: no. 918 and 988.
System variable 918
This system variable control the fields on the invoice itself, found under “Jobs”, “Invoice”.
Click on the hamburger menu and then “Edit data on finalized invoice”. The editable fields then become yellow.
System variable 988
This System variable allows editing of certain debtor information both on the invoice under “Jobs” and in the “Debtor invoice management” under “Finance & administration”.
You’ll find the button under the hamburger menu.
