what customers say about us

"With humor and joy!"

I founded my company with adminster.
I am very satisfied!
Will now continue to work with them.

Michael Dettwiler

adminster then gave us a helping hand with their expertise and ensured that we no longer just had the right turnover, but that our accounting was also in line with legal requirements.

If you are looking for a partner in the area of finance and accounting who can ensure that everything in this area is as it should be in an uncomplicated and independent manner, then adminster is an ideal partner.

Hans Geeler

Very professional and reliable service. The adminster team works quickly and precisely and offers expert advice. We have been working with them since the beginning and have been able to see how a start-up has become a really great SME. I am very satisfied with the collaboration and can recommend the service without reservation!

Marco Licini

We have been working with adminster since this year and are surprised by the good quality. By quality we mean digital processes, direct communication and excellent advice at a fair price. Absolutely top!

Physio Schenk

Professional support in all areas with extremely friendly people. I can recommend adminster fiduciary who wants straightforward, competent, and reliable support.

Madleina Speich

I have been working with adminster for years and am completely satisfied. Whether accounting, payroll administration, taxes or business consulting - I always receive competent, fast and reliable support. The collaboration is personal, professional and solution-oriented. For me, they are the first port of call for all financial and administrative matters. Highly recommended!

We have been working with adminster for over 1.5 years now. They do most of the bookkeeping for us. The cooperation with Simon and his team is very competent, reliable and on an equal footing. We are very satisfied!

Jesse Gerner

I've been working with Simon and his team for almost 3 years now. It has been a pleasant experience all the way. As a lean start-up, we try to do the maximum by our own (As it is the cheapest). Simon supported us in this effort and never gave me the feeling of being a complete newbie (despite making many and repetitive mistakes). I recommended Simon already to multiple other start-ups and companies and had great feedback from them as well.
