Connect EPS SOS and Appointo. Appointments on your calendar, with Arbol.
How it works
A EPS SOS member writes to or calls your organization.
Arbol answers and asks for the EPS SOS order and authorization before offering a slot.
The appointment lands in Appointo, with your clinicians' real availability.
Arbol confirms and reminds it; if the patient reschedules, it moves it in Appointo.
