1. High translation quality

A professional translation company should have vertical expertise across a wide variety of industries. Please note that not every language provider can expertly translate complicated legal contracts, technology documents, or medical papers. Even in a very dry “nerdy” text, mistakes and awkward translations are noticeable. Find a company that has translators who have an in-depth knowledge of the topics related and you’ll rest assured!

Another useful tip is looking for companies with sophisticated and robust workflow management systems, such as the ISO9001 and ISO 17100 certification for professional translation services.
