Jupiter supports technicians who do house calls with their clients. To collect client addresses, edit the service which is available via house call and ensure the "Location" has been specified.
Select your service from the Services tab
Make sure "Available at client's location" is checked off. This will give clients the option to enter their address during booking
Once the appointment is booked, you will see your client's address under the appointment in your schedule, in the client's file, and in your Google Calendar event.
