    Chciałbym bardzo polecić usługi prowadzone przez ową firmę. Błądząc po internecie w celu znalezienia odpowiedniej pomocy rachunkowej natknąłem się firmę ATCA i nie zwłocznie postanowiłem się z nimi skontaktować. Otrzymałem bardzo konkretne odpowiedzi na nurtujące mnie pytania w bardzo przyjaznych i zrozumiałych słowach. Jak na laika jakim jestem w tych tematach Pan Robert z w/w firmy z wielkim zaangażowaniem podszedł do moich problemów i pomógł mi uporać się z nimi proponując swoje rozwiązania. Jestem bardzo wdzięczny za okazałą pomoc i z pewnością w przyszłości nie raz skorzystam z usług Państwa firmy.

  • Robert and his team were fantastic in supporting me with my tax returns. He was very responsive, knowledgeable and explained everything to me very clearly which I found incredibly helpful given my level of French. Highly professional and reliable, he also went out of his way to put me in touch with others for support on various other activities. Highly recommend!

    I received immense support from Mr. Robert and the whole team. They approached my case with particular attention, were available on calls throughout the week, spent as much time as necessary to finalize my case, and on top of that, were always friendly and pleasant to speak to. Definitely recommend them to future clients.

    Je recommande à 100% la fiducière ATCA à Lausanne. Nous avons trouvé une équipe dévouée, un service sérieux et une implication du dirigeant pour nous offrir un service de qualité et sur mesure. Si dans le futur nous devions faire appel de nouveau à une fiducière en Suisse, je referrai appel à ATCA les yeux fermés.

    I’ve found this company using the internet search, so no prior acquaintances or any relation at all – which was kind of a leap of faith, if you will. We had a nice initial meeting and I was offered several solutions for my questions. Basically, after one discussion there I got more information, concerning my issues than for half a year of working with other companies. It is a pleasure to work with this company – they are reliable, their knowledge and skills are extensive and constantly improving. Openness to different solutions is a great plus too. A thing, which is very important to me – since my timetable is really busy – they are fast-responding and fast-thinking. As a result – I am happy to recommend them to other people.

  • I approached ATCA recently as I looked for a reliable tax advisor who could help me with my tax declaration. ATCA proved to be very profesional, quick and customer oriented tax and financial advisor which does not cost an arm and leg. I particularly liked that they spent with us enough time to be sure, that I understood where all the numbers are taken from and how they impact final assesment. We did all our meetings via phone and email, which was very helpful from perspective of our busy agendas. I think that all new commers to Switzerland and people who simply want to understand their taxes would appreciate Robert’s and his team expertise.
