You will receive a notification when service reminders are sent out, or when you are required to make a phone call/print a letter. This can be set up to be automatic, or manual from within your system settings per service type.
How to view service reminder notifications:
Click on the notifications icon in the top left corner. There will be a red bubble with the number of incomplete notifications you have.
Click on the service reminder notification labelled 'Automatic Service Reminders'.
You will see a side window pop up showing you how many service reminders were sent/need your attention.
