I'm assuming you're talking about CMS in this "space", which is to say likely used by small to medium sized companies. Others have spoken to that already.

That said, just to make sure you're aware, some companies pay hundreds of thousands if not millions of dollars (I don't know first hand about millions, but I know hundreds of thousands is easy and I'd easily guess million+ isn't unheard of) annually just in licensing for "enterprise" CMS.
