From the Eziplan Menu:

Appointments - Send Client Schedules

This will take you to the Client Schedules page. Fill out the details required in the search options to filter the schedule you are after (name and dates are most important).

When you hit the "SEARCH" button you will bring up the client's schedule for the period of time selected. Make sure the appropriate contact details (email or mobile) are correct in the options available and then choose your method of delivery (email, SMS or pdf to print off and send) and press the matching button.
