Online appointment booking that never sleeps.
With Terminradar, your customers book open appointments themselves, around the clock — at night, on weekends, or outside your opening hours. No phone call, no waiting, no missed bookings.
Why 24/7 booking makes the difference
Most booking requests happen outside your opening hours.
Missed calls become missed appointments
If a customer calls after hours and reaches voicemail, they often book elsewhere. With online booking, no lead gets lost.
Your team is freed from the phone
Every call for an appointment interrupts the actual work. Online booking handles it automatically — even during high call volume.
Customers already expect it
From restaurants to hairdressers to tradespeople — customers are used to online booking elsewhere and prefer it over a phone call.
