It's similar in The Netherlands. If you are self-employed and have more than one customer it's pretty demonstrable that you are autonomous, can decline work, and the relationship is not solely to avoid an employment contract.

Contrary to popular (Dutch) belief, you do not have to have more than one customer... it's just that if you do it can be difficult to prove that you are autonomous. One test is if you are doing the same type of work that other employees in the company are doing.

I'm not sure how this works for for international agreements (self-employed in NL but only customer in DE).

I'd assume the rules are the same in principle but you would be more likely to be considered autonomous in practice if audited. Also because you're probably providing your own equipment, office etc.

I actually did this for a while - self-employed in NO, only customer in NL. After a while I had more than one customer, making the issue moot :-)
