Our Five Core Values

1. Experts for Complex Matters

We are specialized and provide advice also in complex matters in domestic and cross-border situations. Based on that approach, we have years of experience in these matters and gained expert status. Get in contact with us to see how we may help you.

2. Cooperative & Team Players

We offer special services in tax and law for tax advisors, lawyers, notaries and accountants – to optimize or avoid tax risks. Thereby focusing on the cooperation with the advisor to offer the client the best solution. Contact us to extend your network and options for your clients.

3. Efficient & Cost Transparent

Cost transparency and efficiency are of highest importance. Quality has its price. However, it does not prevent a cost-efficient implementation of a project based on a lean cost structure. We may always provide you upfront with either a fixed fee arrangement or at least a fee estimate.

4. Connected & Networkers

As a boutique firm, we are permanently in contact with advisors in different areas and countries and built up a network. Based on that, we are able to recommend specialists in other areas to our clients. You do not know who is the right match for you? Get in contact with us – we may help you with our network.

5. Digital & Eco-Friendly

We run our firm mostly digital. We communicate via electronic means and avoid using and printing paper as much as possible. Our team is dedicated to use (excellent) public transporation in Vienna to and from work.
