The family has been working with MDG for more than 10 years and apart from the human quality, the professionalism, up-to-date knowledge and advice is superlative and is not found in 95% of similar companies that are basically management companies and not consultancies. Leticia, in particular, is the best prepared person in terms of taxation that I have met in consultancies, after having worked with many in different provinces at a personal and corporate level. For me, the security offered by being in the hands of such qualified professionals is invaluable.

MDG have been saving us thousand of euros in taxes due to their great understanding of how online companies work. They have been preventing us from having few troubles too, by explaining us how things need to be done in order to be able to deduct this or that, or so that we don't loose our intracommunity VAT number.
