In my case the turnover is around 100k€. The cost are based on turnover for most of them.

For the general question about rules etc. At my level, it is a non problem because everything is taken into account by my accountant. It means, it is very easy. Also, the GmbH structure is the same for everybody, it means, everybody must follow these strict rules and as a customer told me: "You have a GmbH, we can trust you that you do the things the right way".

So, for me, these relatively small requirements at the start are a way to keep the non serious people out of business. This is good for the trust when running your business on the long run. I like it this way.
