Could anyone tell me if there is a way to make fields mandatory (required)?
I have put some custom fields on the client and invoice sections, but would like these to be required fields so that a user must fill them in and failure to do so would result in an error message being displayed and them not being able to save?
Although I mention custom fields, it would also be nice to have this option on standard invoice plane fields as well.
May this should be a feature request if it isn’t already?
Thank you for your great work!
