You can add a specific question relating to any service offered in your Online Booking process.
To do this go to the specific Service that is enabled for Online Booking and view the Online Booking area
Once Online Booking is switched ON, you can add a specific question you want to ask your client during the Online Booking process that relates to just that one service.
This question will be shown during the online booking process if a client selects that specific service and their answer will appear in the Booking Notes area for the booked appointment in your calendar.
Click the green Update button in the top right corner when you have finished.
