Clients choose a service, their technician, add-ons and a color, then a time that really fits. Add-ons adjust the price and length on their own.
Your flow, your way. Your salon defines the booking flow: choose the steps clients go through, put them in your order, and skip the ones you don't need.
Availability accounts for each technician's pace and cleanup time, so the day never gets overbooked.
Client membership
Clients who keep coming back.
Your clients get their own space: they earn points with every visit and keep track of their appointments. It's free for them, and one more reason to come back.
