The short answer is Yes. All clients who wish to book appointments online are required to register and verify their email address. This is mainly to reduce the risk of scams, bots making bookings and to enable the use of many of the booking limits features of the system. Registration is simple and the system only requires First Name, Last Name, Email, Time Zone and a Password. 

Having an online profile also allows clients to manage their own appointments, and if allowed by your business' Client Calendar Options, to access and download their appointment receipts.

If a client prefers not to create an online account, or is the type of client who doesn't have an email address, like an elderly client, appointments will need to be booked by you and your staff from the admin calendar. 

If your client is related to someone who can book and manage appointments on their behalf, like a child, you can setup a Linked Client profile so that person can login to book appointments on their child's behalf.  Check out our Linked Clients instructions and video here.
