For some reason, Bitrix24 isn’t widely known — and I think that’s a shame. The program combines a social intranet system with CRM tools that include contact tracking, sales funnel management, messaging, activity planning and calendars, all of which enable your team to quickly manage important pieces of information from within a central program.

Speaking of intuitive, that's how I'd describe Bitrix24 on the whole: It's admirably easy to pick up and use. Anyone familiar with Facebook or LinkedIn won't need a lot of training, if any at all.

The first thing Bitrix24 does when you log in is provide a lot of information. The workspace main page is packed -- there are three columns of links to workspaces and workgroups, an activity stream, client apps, and tasks... you can extend Bitrix24 into a full corporate intranet by using its employee directory, company organization, and organization chart features.
