Whether you run a salon, a clinic, a consultancy or a training centre, your calendar is your revenue. Double bookings annoy customers; no-shows waste paid staff time. Both are avoidable.
A calendar that checks before it saves
Zyntra Appointments is built around "the calendar that never books a time twice". Every booking is checked against staff hours, breaks, leave and room capacity when it's saved.
Services set up properly
Each service has its duration, buffers, capacity, price, online or in-person option, and tax. Buffers matter: they give staff time to clean up or prepare between appointments.
A booking page on your own domain
Clients book on a page built for phones, in your language — Arabic included. You can use your own domain.
The front desk
Walk-ins, check-in and payment on the spot, in the same calendar.
Fill cancelled slots
A waiting list offers a freed time to the first waiting client.
Regular clients
Repeating bookings weekly, every two weeks or monthly — up to 52 times.
Reminders that cut no-shows
Booking, move and cancel notices, plus reminders by e-mail and text. Optional cancellation fees depend on your cut-off settings.
Packages and coupons
Percentage or amount discounts, with the discount calculated by the server, not typed by hand.
Online visits
For online sessions, a Microsoft Teams meeting link is created with the booking.
Reviews and reports
A star review after a completed visit, shown once you approve it, and eight reports for any period, each exportable to CSV.
Ask Flowrica
"Who's booked this afternoon?" Flowrica answers — and can book an appointment for you, with undo.
Who it suits
Salons and spas, clinics, physiotherapy and wellness centres, consultants, tutors and training centres — any business that sells time with a person or a room.
