Appointment Reminder stands out as the best appointment reminder software not only because it lets you integrate different calendars such as Outlook, Google Calendar, and iCal, but also because it helps your business to send timely reminders to your clients 24 hours prior to their scheduled appointment.
The price of the software ranges from $19 to $150 a month depending on how many appointment reminders you need to send out. For example, you have a small business which caters at least 100 to 300 customers a month, then you can either choose the $19 a month of the $49 a month fee. On the bright side, you get to be a premium user for 2 months without paying for an exclusive package.
