Having a good magician on hand is a very important option.
For a magician, being able to manage your bookings, calendar, events, custom requests, etc … with WhatsApp is the best way to manage your agenda.
A client, agency, may want to know if you are available at any given time on a specific day and WhatsApp is the most agile way to manage these requests.
