Sole Proprietorship in Switzerland

7 min readLast updated 2026-05-06Switzerland

The sole proprietorship is often the simplest way for an individual in Switzerland to start operating. It is lean, relatively fast, and often well suited for many small service-based or solo setups.

At the same time, it has clear limits: more direct personal exposure, weaker scalability, and in some situations a less formal market perception. Anyone choosing a sole proprietorship should understand that simplicity has trade-offs.

What a sole proprietorship is

A sole proprietorship is a business form centered on one individual founder. It is often suitable for small businesses, simple service models, and early market phases. Compared with capital companies, it is lighter and easier to set up.

When it can be a good fit

A sole proprietorship often makes sense when:

  • you start alone
  • the business is manageable in complexity
  • risk is limited
  • you want to start with little administrative weight
  • you first want to test the market

Typical examples: consulting, coaching, small agency work, creative services, small-scale retail, early solo digital offers with limited structural complexity.

Where it is strong

Easy to start

The sole proprietorship is usually simpler to start than a capital company.

Lean setup

It fits founders who do not need a heavy legal structure immediately.

Less formal complexity

Especially in the early phase, that can be an advantage.

Where it has clear limits

More direct personal exposure

This is the central point. If the business creates real liability risk, the founder carries it more directly.

Weak structure for larger teams

The sole proprietorship is built around one individual, not around a clean multi-founder structure.

Weak fit for investors or complex ownership

If equity logic, investors, or structured scaling become relevant, it quickly becomes limiting.

External perception

In some contexts a sole proprietorship is completely sufficient. In others, a GmbH or AG signals more structure and seriousness.

Who it often does not fit well

  • founder teams
  • businesses with higher liability risk
  • ventures with investor logic
  • strongly scalable startups with more complex ownership
  • businesses where a formal company structure is expected from the start

Typical decision situations

Case 1: Side-hustle consulting

Often a reasonable fit if scope and risk remain limited.

Case 2: Digital product with multiple founders

Usually a weaker fit because ownership and roles are better handled through a capital company.

Case 3: Early test phase of an offer

Can be a sensible option if you want to test leanly and the risk is under control.

What to check before choosing it

  • how high is the real risk
  • are you truly operating alone
  • how important is liability limitation
  • how much external professionalism is expected
  • is the sole proprietorship only a temporary test setup or meant to carry the business longer term

What comes after choosing it

Even a sole proprietorship needs discipline. You still need to think about:

  • name
  • domain
  • bookkeeping
  • business bank account
  • AHV and social insurance
  • VAT relevance
  • customer contracts
  • privacy

When a later upgrade may make sense

A later move into a GmbH or AG may make sense when:

  • risk grows
  • more people join
  • the business becomes larger
  • investors or larger partners become relevant
  • the current structure no longer fits
