The best translation agencies in Spain


If you want to know which the best translation agencies in Spain are, you’ve come to the right place. The need for a translation service arises in many areas of business and private activities, from the internationalisation of a brand to a sworn translation for a legal or notarial procedure.

What do the services of a translation agency consist of?

When working with a translation agency, the process tends to be as follows: 

  1. You contact the translation agency to start a project. This project may be a traditional translation, a transcription, subtitling…
  2. Some agencies – such as BigTranslation- offer the option of calculating your translation fee automatically. You will need to provide the file or the text that you want to translate and choose:
    1. The source language and the target language/languages for translation.
    2. The service that you want to contract.
    3. Any extras that you want to include (such as proofreading, or the urgent service option)
  3. If you work with a translation agency that provides an instant quote, the whole process will take place online. You finalise the order and, from that moment, the agency takes over.
  4. The translation agency chooses the translator with the profile that is most suitable to carry out the project, while adhering to the specified timescale.  
  5. Once the work has been completed, you will receive a notification with your translation.

What should you focus on when contracting a translation agency?

There are various important aspects that you should keep in mind when looking for the best translation agency for your business:

  • Translations are not automated: This may sound rather obvious, but it is very important. In order to guarantee the quality of your projects, stay away from automated translations.
  • They only work with native translators: At BigTranslation, for example, we take it one step further: all our translators are native speakers and, they live in the country of their native language. This enables them to grasp all the nuances within your translation.
  • They go beyond the basic translation service: Some of the most sought-after services  that the best translation agencies include are:
    • Translation with SEO optimisation
    •  Website translation
    • Audio and video transcription
    • Sworn translation service
    •  Proofreading and checking of texts
  • They offer economical prices: In particular, if you are looking to establish a collaboration over the medium/long term, ensure that the translation agency you choose offers reasonable prices that allow you to scale up your projects without making unaffordable investments. At BigTranslation, for example, we offer translation tariffs from €0.03/word.
