The path has three stations and you start at the one that matches your situation.
One contact instead of eight
Opening a business here means forms in a language you may not read, calls to offices during your own working hours and documents you are asked to sign without an explanation.
Opening a business from abroad, for example.
You decide what you want to achieve.
The requirements of the authorities are clarified and negotiated here and you are informed about every result.
Wherever your case is
The practice is based in Zug and works in all parts of Switzerland. Viewings and meetings with authorities or landlords take place on site.
The work is done in German, French, Italian and English. Swiss German is spoken as well.

Clear scope
Before any work starts, you know what is included and how it is billed. Anything beyond that scope is discussed and agreed in writing first.
Implementation
Applications, correspondence and appointments with authorities and third parties are handled here.
