A service bureau is any type of company that offers business services to their clients, in exchange for some type of compensation. The term has often been used to describe any business that offers technical support services to companies of every size, as well as a kind of financial institution. In many cases, the support offered by service bureaus allows companies to outsource essential functions to the bureaus, thus decreasing the operating cost of the customer. (wisegeek)
