control. Making suggestions to management on how to improve operations while reducing expenses can cause an accountant to be considered invaluable.
Good lord! Doesn't the sarbanes oxley act forbid book-keepers & auditors from getting their hands into the strategic & operational sides of the business? If an auditor gets into advice giving, she is no longer OBJECTIVE.
In my business, I prefer to hire hands-off auditors so they can count the beans in an OBJECTIVE, 3rd person fashion. If an accountant has incentives to see certain projects do better, we can't depend on her to count the beans objectively anymore. She would become tempted to "manage" the cash flows and books, which means the numbers get "managed."
I prefer to have dumb as nuts accountants because their numbers are more reliable; they don't "manage" the beans. That's why those with city college educations are more valuable.
Of course, if you want to push the line on your taxes or manage your earnings because you're a public company, then you should hire a shark from Stanford law school to do them for you. But that's another story.
