Well the primary reason as to why services are outsourced is because they are a cheaper medium of getting work done.

Outsourcing initially entered the business world during the 1980s and generally addresses to non-core functions from inner invention to an external entity concentrating primarily on the administration of that process. The decision to outsource is generally taken in an effort to lessen the costs of the company, transmitting or protecting energy aimed at the competencies of a particular business.

Though generally applied interchangeably, outsourcing is quite diverse from off shoring. Primarily and traditionally, outsourcing basically is an expression similar to the organization of labor inside and amid societies. In the present day international market, outsourcing has made itself available to a number of institutions on the international level.
