ViSof and Calendly, with the same appointments. With Arbol, with no manual copying.
How it works
The patient asks for an appointment by phone or WhatsApp.
Arbol creates it on the ViSof calendar, with real availability.
It brings it to the clinician's Calendly calendar, with the link if it is telehealth.
If the patient reschedules, it moves it in both.
What each one is
Healthcare provider management software
ViSof
ViSof DDI Software SAS is a Colombian company that develops SIIPS, an information system that brings the clinical, administrative and financial processes of IPS (healthcare provider institutions) into one platform. Its modules cover appointments and online booking, specialty-specific clinical records, service orders, billing, RIPS (Colombia's standardized service-record files), accounts receivable, claim denials (glosas), payroll, accounting and inventory. It has options for dentistry, clinical lab, imaging and outpatient care.
An IPS uses SIIPS to book appointments, keep clinical records and bill with RIPS files and electronic invoices from a single system.
On May 5, 2026, Colombia's Ministry of Health and Social Protection granted SIIPS technical conformity validation for the Digital Care Summary (RDA) in the Patient and Outpatient Consultation scenarios. Source: visof.com (opens in a new tab)

Calendly
Calendly is a meeting scheduling platform founded in 2013 by Tope Awotona. Each user connects their calendars, sets their hours and shares a link or booking page where the other person picks an open time. It also sends email and text reminders, lets invitees reschedule without the back-and-forth, and can collect payment up front at booking.
Share a booking link so patients pick their appointment time based on each provider's schedule.
According to the company, more than 50 million people use Calendly, and more than 1.3 billion meetings have been booked on it. Source: calendly.com (opens in a new tab)
Calendly publishes a REST API, with OAuth 2.0 or a personal access token, to book meetings and read and write scheduling and contact data; its webhooks fire when someone books or cancels, and the booking page can be embedded on a website.
