Running Manual Appointments
The Manual Appointment feature allows you to create appointments that haven't been entered into your CRM but run precisely the same. It also makes it easy to transfer from the manual appointment to creating an appointment in your CRM, importing the manual appointment into this and syncing to your CRM.
Another added benefit is that Manual Appointments is an excellent sandbox for new users to practice using all the functions of running appointments but not having to worry about this data being synced into your CRM and causing confusion on what valid appointments are.
