* Ltd./foreign companies with a German registered office: *Proof from the tax office showing the establishment of the Ltd. or an excerpt from the commercial register*
* Partnerships (law firms, architectural firms): *Partnership register*
* GbR: *Partnership agreement or guild certificate, proof from the Chamber of Crafts, business registration*
* Associations: *Register of associations*
* Sole proprietorships: *Identity card and business license*
* Freelancers: *Identity card and proof from the tax office / reply letter from your tax office showing the registration and the allocation of the VAT number*
* Medical practices: *Entry with the Chamber of Physicians or certificate from the Association of Statutory Health Insurance Physicians.*
* Law firms: *Entry with the Bar Association*

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.sipgate.de/cloud-telefonanlage/en/getting-started/alles-fur-den-start-mit-sipgate/wie-registriere-ich-mich-als-unternehmen-bei-sipgate.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
