The best thing about this service provider was its customer support team who were always ready to help me with my queries regarding their product or any other related matter I had! They are very professional as well so there's no worry at all when you're using them for your business needs because they will provide quality work within time frame given by client/customer himself without compromising over his expectations from us (the translator).
There wasn't anything which i disliked much but if possible then please try not having too many files under one project since sometimes we have issues while uploading more than 3-4 pages together hence some times delay occurs during upload process due to such reason only!! So be careful before choosing anyone else rather go through reviews available online firstly like google search engine etc., otherwise everything would've been great. We use gts translations primarily for our websites where clients can translate English.
