During tax season, I set up a rather simple way to schedule appointments. The system allows you to see what my availability, then you can schedule your own appointment. The system then sends reminders for appointments via email and text. You can also cancel or reschedule your appointment.
It eliminates phone calls, reminders, missed appointments and general confusion.
You can also upload files to me, as well as send messages.
It is located on my website, but there is also a web page that is dedicated to using it.
