Is it even possible to audit the cloud pricing? They just give us a number and we pay.
On AWS, you can enable CUR (cost and usage reporting) and get detailed, line-item billing figures that you can audit.
And naturally, companies like Cloudability [now Apptio] and others have sprung up to do parts of this for you [at a fee, of course...]

I'm sure other cloud vendors have similar functionality (because they need this on the back end to do their own billing anyway).
