There are many translation companies in India, UK, Canada, France, the U.S., the UK, Spain, Germany, and other parts of the world and picking the best one is not always easy. You could use software for translations, but human translators are better because you will avoid language ambiguities. Knowing what makes a good language company will help you make an informed decision.
Consider the professionalism offered by the Professional translation company. Go for a company that has translators who are trained in accredited institutions. Training is the only way a translator will know about the most appropriate mechanisms for different scenarios. A good translator is one who belongs to a professional body since professional bodies have strict codes of ethics that they have to abide by.
Knowledge of the languages the translator is switching to and from is not enough. A good company has employees who have in-depth understanding of language flavor. As an example, French in Canada and French in France have several differences since they are spoken in different settings. It is easy for a translator to get the wrong meaning of what is being said. A good translator is one who translates the message, not the words.
Consider the number of types of translation on offer. Go for a company that offers different services under its roof, from the interpretation of one-page birth certificates to rewording in international conferences. Go for a professional translation company that offers translation and localization, interpretation, e-learning services, content production and publishing services, LMS, LSA, language training, transcription, multilingual research, and multilingual printing services. Good companies even offer such IT services as search engine optimization, software localization, and Web design and development.
A good language translation company is one that puts the needs of the client first. Go for a company that has been in business for several years since the interpreters in the language translation company will have learnt from their mistakes and successes.
A good company is one that offers customer support round the clock. Consider the fluency of the translators (in written word and verbally) and how responsible they are. Cost considerations should be secondary if you want the best translation company.
