As long as you are just booking a regular appointment, and nothing goes wrong, it works great.

If you have any problems, or need help in any manner, good luck getting someone on the phone. All they want to do is email and refer you to hours upon hours of videos to watch. So a problem will take you days to get it resolved when it could have been resolved with a 3 minute phone call. I'd gladly pay three times what I'm paying today to have a customer service phone number that went to a department that could help me when I have an issue as opposed to their email system of referring me to videos.

I had used ScheduleOnce integrated with Outlook calendar for scheduling appointments and checking availability for about a year without problem. The website is simple to use and configure for users. Once setup, you have a custom URL that you can share with clients and potential clients alike. As long as you set your availability and fill your calendar with personal and business events as well, you can be sure SO will only display truly available times to your clients and prevent scheduling errors.

After a year or so, SO began to allow clients to schedule calls at times my calendar had been marked busy. In addition to this, some scheduled calls would not appear on my Outlook calendar. After searching support and contacting support, it was suggested I uninstall and reinstall the desktop client application. This fixed it immediately but the issue returned again in the future. Support was fast to respond and suggested another technical fix which allowed it to refresh its connection. It was later explored by the support team and an update was issued which has since resolved the problem. It was a frustrating time during this period but SO's support was professional and helped resolve it in a reasonable amount of time.

Scheduleonce is really a wolf in sheeps clothing-- while it appears to be a simple scheduling system, it really houses a comprehensive work flow system. Scheduling is integrated directly with google apps or office 365, calendars, so it's always up to date. Rule based scheduling allows to maximize user flexibility in booking, but prevents overscheduling. I have mine set up to limit new appointments to three per day.

Feedback to users is first rate with a systemized set of follow up reminders, directions, and a follow up once the meeting is concluded.

Setup is not intuitive and requires a bit of hand holding. The view is worth the climb though-- the system saves way more time then you'd expect once you've perfected your workflow.
