Common challenges for clinics with many professionals and patients booking by phone.
The phone rings all day
Patients choose a service, professional and time on your clinic's page, including evenings and weekends. They see only times that are actually available.
Start online registration
A patient doesn't attend or cancel
Require payment at booking for selected services. Before the appointment, patients receive a reminder and can confirm or cancel directly from the message.
Protect your appointments
Payments and invoices at the end of the day
Money goes to the clinic account, and a sales document is issued after payment in inFakt, Fakturownia, wFirma or iFirma.
Automate billing
Patients complete their own booking. Zencal updates the professional's schedule and sends the necessary messages.
Each service has its own duration and price. Available times come from the professional's schedule and connected Google, Outlook or iCloud calendars.
The booking goes to the right person's calendar and the patient receives an email confirmation. If prepayment is required, the appointment is confirmed after payment.
You set when to send it, for example a day and a few hours before the appointment. Reception doesn't need to call every patient.


Zencal brings registration, schedules and payments together in one process.
