A translation agency takes care of translations and may also offer related services such as proofreading. Language service providers, on the other hand, take care of the whole language package. The wide range of services that they offer usually extends from translation to innovative technology-driven corporate solutions. Whether it is a complex translation project, a multilingual advertising campaign abroad, or documents for corporate communication – language service providers have the needed experience and technology.
