  • Employee onboarding, departures and ongoing changes
  • Travel expenses, allowances and company-specific requirements
  • Preparation for and support during payroll and social security audits

Personal and versatile

Who we support

We support individuals, companies and organisations in a wide range of situations — employees and civil servants, self-employed professionals, freelancers and entrepreneurs.

Our clients include doctors and other healthcare professionals, lawyers, architects, IT and other service providers, as well as businesses in retail and care. We also work with digital business models such as content creators and influencers, and with associations, foundations and non-profit organisations.

For us, the specific question matters more than industry or size — from personal and professional development to entrepreneurial decisions, start-ups and financing, processes, accounting and ongoing commercial support.

Clear boundaries. A strong network.

We only promise
what we can deliver.

We do not develop software, perform valuations ourselves or provide specialist advice beyond our legal authority. Where additional expertise is required, we involve IT providers, tax advisory firms, legal advisers or valuation specialists.

You still retain one dependable contact who understands the overall picture and coordinates everyone involved.
