Plimus does not offer Live Chat to its services since most of the people contacting them would be of a confidential nature. However they do offer Live Chat option for its vendors so that the vendors' potential customers can chat with the vendors before the purchase. There is the option in the Customize Order Form which would allow you to add the Live Chat option in it. In the vendor control panel, you can set up this option and install the apps on your computer to allow you to conduct live chat. You can find more about the option at http://www.plimus.com/live_assistance.shtml
