Add it
On Schedule → Calendar, create an appointment: choose the customer, the service, the provider and the time.
Existing or new customer
Start typing a name, email or phone number to match an existing client, or enter new details to create one. Either way the appointment is added to that client's history.
Notifications
The customer receives the same confirmation and reminders as an online booking, as long as you have an email address for them and notifications are on.
Outside your hours
You can book a time you do not normally offer. Your published availability is unchanged — only this appointment is added.
