Hi,
Salesforce Live Agent is a native Salesforce tool that provides the ability to communicate in real-time with your web site users.
Live Agent is superb for those who have a limited size support team but want to extract maximum return and effectiveness from them. Unlike a phone call, where one agent can only manage one customer at a time, using Live Agent each user can be partaking in numerous simultaneous customer interactions from just the one screen. It can also be an effective way to alleviate pressure from a struggling phone support team by diverting some customer traffic to an alternative channel.
Thanks.
