Create Customer Reminders (Tools Menu)...

 

Create Reminders allows you to set up MacInvoice to automatically inform you when it's time to bill selected clients.

When you select Create Customer Reminders you will be presented with the screen at right. Here you have the option to Create Reminders or View All Reminders.

 

This screen will contains a list of all your customers. Highlight one, then click Create Reminders. You will then see the screen at left, which allows you to add the necessary criteria to the reminder.
When you check your reminders, the screen at right will appear and display your reminders for the day. It will continue displaying a reminder until you select the reminder and press the Update button. At that point, the reminder will be updated to the next scheduled day.
