Google trains its machine translation engine with billions of words of bilingual texts, giving it a nearly exhaustive ability to translate various topics. However, the broad range of materials used to train the engine also means that the terminology and language tone that it produces is also generalized and not specific to any particular industry. Companies can use their own bilingual data to train their own custom machine translation engines creating a machine translation engine that "knows" exactly what tone is expected and how to translate industry- and company-specific terms. This creates a specialized machine translation engine that is far more effective at its limited task than Google Translate would be.
