The support we've received from Sctech has been excellent. We use online chat whenever we have a quick question, and it saves us hours of trial & error or searching through the manual (which is written well but not specific enough to our business.)
It runs on Windows, Mac and Linux, so if you have a mixed platform environment like we do, it's a great fit. The whole system is really world-class and they offer superb customer support.
The products are user friendly and very easy for a beginner to pick up with the guided instructions that Sctech provides on their help site. Sctech is very responsive when you need their assistance!
