Who This Collaboration Is a Good Fit For

You’ve come to the right place if you’re looking for personalized and structured tax advice and value a digital, hassle-free collaboration.

I primarily serve

  • corporations (e.g., GmbHs)
  • freelancers and self-employed
  • individuals individuals 
  • real estate companies and other asset-management structures (e.g., real estate GmbHs or GmbH & Co. KGs)


Currently, I do not regularly advise on cash-intensive business models (e.g., the restaurant industry), complex e-commerce structures with extensive platform integrations, or criminal tax law cases. This allows me to focus on the areas where I can best support my clients.

What You Can Expect From Me

As the owner of my firm, I am your personal point of contact. Throughout our entire collaboration, you will be working with the same person who is familiar with your tax situation and handles your matters.

In doing so, I place particular importance on:

  • a dedicated point of contact throughout our collaboration
  • clear advice without unnecessary specialist jargon
  • digital collaboration via DATEV
  • structured processes and prompt responses

Digital Collaboration

Despite our digital collaboration, I value personal interaction.

Our collaboration is entirely digital. Through MyDATEV, you can securely exchange documents, send messages, work on tasks, and provide digital approvals. The MyDATEV app also gives you mobile access.

Meetings take place by phone or video conference. This keeps our collaboration efficient, location-independent, and personal at the same time.

Here's how the collaboration begins

📩 Getting in Touch
You can contact me via my contact form. I usually get back to you within one to two business days.

💬 Initial meeting and initial assessment

If we believe a collaboration is a possibility, we often start by scheduling a brief, cost-free initial meeting. Where appropriate, you can send additional documents – such as tax assessment notices or your latest annual accounts – electronically for further clarification. .

✍️Digital mandate assignment

If an understanding is reached, you will receive the mandate documents digitally via FP Sign—no registration required and free of charge for you. 

🤝 Start of the collaboration

Once the assignment has been confirmed, we’ll begin our collaboration in a structured and fully digital manner.

Transparency fees

Fees are generally determined in accordance with the Tax Advisor Fee Regulation (StBVV). Depending on the service and the client’s needs, flat-rate fees or hourly rates may also be agreed upon.
