They say about us…
Skyrent P.C.

My experience with Atlas Consulting started several months before the incorporation of Skyrent company in Thessaloniki. While Skyrent was just a business project, I was keen to find the best consulting firm for the development of this project. You should know that I do not have my residence in Greece and I do not speak Greek.

After spending some time looking into business directories and on the Internet, I came across Atlas Consulting website. My first good surprise was to discover a website written in English. My second good surprise was to discover Sousana and George. From the first contact I realized that I was talking to professional specialists with high-level expertise.

Sousana and George accompanied me throughout the development of my business project, from the very first step to the last one. They answered all my questions with patience and professionalism. Whether in their office, on the phone, by email or on Skype, they have always been available.Thanks to their effective guidance and support, Skyrent is now a reality.

I recommend Atlas Consulting without reservation to local and foreign entrepreneurs looking for sound advice and efficient support to business creation in Greece.

For the foreigners that have a limited knowledge of greek language and by far limited understanding of the Greex Taxation Law, A.TL.AS  Consulting people are for sure, the moste suitable people to take care of all our tax matters and our annual tax returns.

They have deep knowledge and expertise for international tax planning issues as well as they are able to give us solutions in order to protect our greek property. They are bringing results accurately, immediately and consistently as they speak fluently english, and they transform the frightening tax procedures into an easy and fast solutions for a foreigner . I have no words to express as much as I want, how precious and  useful they are. I strongly recommend A.TL.AS Consulting team!

It is quite demanding for a foreigner to understand the complexity of the Greek Tax System. A.TL.AS Consulting offered me a very smooth and gentle experience regarding my tax obligations in Greece. All the problems that Ι had faced, were solved accurately and effectively.

Sousana and Georgos Kalfas are the heart of their company Atlas Consulting. Both are dedicated professionals with different and excellent skills and they have helped my company with valuable advice. Their knowledge is not only updated on the Greek changing reality but also on European tax legislation. They really have helped me with finding the best solutions and informing me well ahead on issues that concern my business.

Furthermore I had the pleasure to work with them as president of the Non-for-Profit organization “The Dutch Greek Society of Northern Greece”. Also in this case both helped at a brainstorm session to solve tax issues concerning the organization of a voluntary workshop.

Last but not least they have the excellent quality of a personal touch and to exceed your expectations.
