Appointment-based operators need a quick way to welcome new clients and confirm that a booking has reached the business. GigaBook handles online appointments, client records, custom form answers and invoices, while Mobile Message can send a practical text at the right point. Through Zapier, New Booking, New Client or New Invoice can start an SMS workflow without manual copying.

Use New Booking with Send SMS to confirm the appointment details or explain what the client should do next. New Client can pair with Create Contact to place a new person into Mobile Message, ready for future communication. New Invoice can also trigger Send SMS for a payment reminder or internal follow-up, using only the information supplied by GigaBook. The connection is a set of one-way Zaps, not a native two-way update between booking and messaging records.

Select the GigaBook event in Zapier, choose the Mobile Message action and map the available phone and appointment fields. Keep reminders clear and include the business name so the recipient recognises the sender. This gives booking teams a dependable message step while GigaBook continues to hold the appointment information.
