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.

Very professional and reliable service. The adminster team works quickly and precisely and offers expert advice.

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!

J
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.
