The internet has made business a global endeavor. Anyone, anywhere can now have access to wares advertised anywhere else. However, web marketers in the United States for example will have their sites in English which limits buyers to English readers. This leaves a large portion of the global market unable to interact with the site and results in lost sales. Although there are free translation services in the web, the results are sometime still unreadable due to severe grammatical errors. Thus, professional translation services are needed to fully market products in a global environment. Thus, to enter into a global business, the language barrier is the first problem that needs to be dealt with.
Also, many products are not simple click purchases. Many require correspondence with the marketer and the prospective buyer outside the website. A prime example is webhosting. Although marketed in the web, webhosting marketers will require official correspondence and documentation before actual sales. For example, webhosters in England can service people in France and nearby Scandinavian countries, all of which are not english speaking. This would require extensive language translation services before sales are finalized.
