help.com will be coming out with something great soon, they are under new ownership.
We use Tawk.to, it's free and is very very good chat. We don't know why to pay if there is an hosted product that works perfectly!
Which is the Best Live Support for Hosting Company?
Right now I am using live help messenger.
Suggest me some other live support software which is more comfortable for the clients.
We use LiveChatInc (sales) and also LivePerson (support) - we're looking to shift all support onto the sales one as it is working liking a charm and cost efficient.
