How can I set an automated Due Date Reminder for a Parent/Student Slip?

You can optionally automatically send reminders on the Due Date for a Parent or Student Slip.

When configuring the Slip use the option 'Send Reminder on this date', if you select Yes then on the Due Date a reminder will be sent via email (for parents and students), and SMS if your school has this enabled and the parent is subscribed for SMS. There is no SMS facility to Students at the moment. 

Please note that the automated due date reminders will only be sent to Parents/Students who haven't responded to a Slip.
