this works especially well for small businesses who simply want a no-hassle, great-to-use live chat system
I am going with Zopim for my chat platform as well. Excellent features and a great team cumult.com
In terms of backoffice support - the best choice available.
Without any doubt the only service that manages to both have advanced features and user friendly interface.
This live chat enables me to conclude a report about the info of my website visitors. It really works for me.
