consultant

Experienced professional who provides expert knowledge (often packaged under a catchy name) for a fee. He or she works in an advisory capacity only and is usually not accountable for the outcome of a consulting exercise. Some consultants (like Peter Drucker and W. Edward Deming) have brought dramatic shifts in management thinking and improvements in the performance of organizations.

Get this answer wrong and you could leave bags of money on the table--or worse, send customers running into the arms of the competition. When Apple sliced the price of its iPhone by a third after only two months on the market, even loyal customers screamed, forcing chief Steve Jobs to apologize and offer a partial rebate. Consultants get paid handsomely to help companies arrive at the right price.
