Best plugin to convert Potential Prospect to Potential Customer.

I am using Formilla Live chat plugin ,after using trial version, I went for paid version.
This is the best plugin and does exactly what it says and as expected .
After googling and searching tons of plugin for live chat ,found this one pretty reasonable,simple to use for both customers and owner.
It brings your blog live and helps you to connect immediately with anyone who visits your site,which I’m using to increase my offline business.
I also liked the customisable aspects like changing icons, colour and multiple chat option in paid versions.
Chat transcripts and Active Visitor along with Gtalk makes it simply must have wordpress plugin.
Don’t lose your next potential client.
This plugin won’t have 5 stars without their incredible developer and support team , so Keep up the Good Work
