Testimonials
BLS are a fantastic translation resource that we regularly draw on. They are very responsive, often returning work earlier than requested, and are a great team to work with. We look forward to continuing to work with them.
We're happy with choosing Business Language Services as our translation partner. When needing to go external for our translation services, we needed a reliable and timely translation service that would suit our need to translate both short documents, like news stories and webpages, to long documents, like policies and booklets. Business Language Services have provided quality Welsh translations, in realistic time frames, with fast responses to requests.
Business Language Services have recently supported us with a large translation and interpreting job and were extremely supportive, flexible and professional. I would highly recommend them.
We'd like to thank you for all your help and hard work on this project. Your communication was swift, friendly and professional and the project was completed very efficiently. The documents themselves have been translated to an excellent standard and we appreciate your translators' attention to detail. I'm sure the customers of the RSNO who speak any of the 7 languages will appreciate being welcomed to our website in their own language!
We were very happy with the service provided, both in terms of the quality of the translation and the timeframe within which the work was delivered. Thank you!
We have been working with Business Language Services for the last two years on our project to update our Instructions for Use (multi-language version). There were 17 languages covered in this project and the services provided by this company have been excellent. Great communication, quick timeline and flexibility to suit our needs.
BLS has assisted us with the translation of our machine manuals and screen content for our PLC controlled HMIs. They have been particularly adept at understanding the engineering terms and technical nature of our requests and have translated these into not only the more commonly used European languages such as French, Spanish, Italian, etc, but have also supplied us with Simplified Chinese and Hebrew translations.
BLS were very prompt in their attention and easily understood the brief that we had and quickly and accurately provided the details needed for a reasonable cost in a professional way.
I commissioned Business Language Services to translate a technical engineering website content into Japanese and have been very happy with the service. Their communication and how they address this project has been very professional. The translation went very smoothly, and presented back to be for use very clearly. The timing of the project was fantastic, it was undertaken in a very reasonable time. We experience no issues the entire project from quote to completion was perfect. Very happy with the service.
We have always found Business Language Services to be extremely professional and efficient. You always manage, somehow, to accommodate our requests even those requests at rather short notice. Would highly recommend your services to others. Long may it continue!
We have used Business Language Services a couple of times now and they have always been really helpful and quick at responding. We initially approached them with a query that we had come across for the first time and they were excellent at answering our questions, providing guidance to us and being able to carry out the specific task in a timely manner.
