Germany insolvency can take a decade, make getting a flat or even keeping your bank account a challenge and rarely results in debt relief to boot [1].

What would you need to mess up to be liable for huge sums as a single consultant company?
Suppose you find out your cvs editor infringes on a patent and you’re liable. Suppose some business suffers data loss and sues. These things do happen in Europe too.
Also, it’s just a matter of professionalism. A sole proprietor isn’t very professional and many medium-size businesses won’t do business with sole proprietorships.
Imagine if you’re a consultant and for whatever reason, you get sued or worse. That’s what the LLC is for.
You can get the simple company type (disregarded entity) and all the advantages of limited liability with an LLC.
