Before you plop down a lot of money for a fancy videoconferencing system, check out what Google is doing with Google Hangouts. Your clients might already be subscribed to Skype, but there’s a good chance they are familiar with Google (since 80 percent of the world uses Google as a search engine and there are over 425 million Gmail users). Google Hangouts is an easy, free videoconferencing solution for up to 10 people. You can also share files with conference participants by using Google Drive. Finally, download the Google+ mobile app to videoconference from your smartphone.
