I'm a pupil from Germany, I'm 15 years old and I want to sell a product online.
However, it's not as easy as it may sound. The first problem is that I am not allowed to sell things before I'm "unbeschränkt geschäftsfähig" (legally competent), and this is normally the case when I reach the age of 18. Fortunately, there is a law that can make me "unbeschränkt geschäftsfähig" before if my parents allow this.
The real problem is that I cannot find any online payment system that allows me to use it because I'm underaged. I would like to sell under my own name, so asking my parents for doing this for me is not a really good option in my opinion.
Here are some of the payment systems I found:
(You don't have to read through all this stuff.)
They would be great. Unfortunately, they want me to be full-aged ("volljährig"):
GiroPay seems like a good choice. It looks very complicated and seems to want me to be full-aged, though (at least they offer a service to "let my clients approve that they are full-aged"). On the other hand, I couldn't find the requirement "full-aged" in their AGB. They are probably too expensive for me because they want a €99 fee once and €9.90 for every month after that if I want to use their payment service provider. Again, this stuff makes it pretty complicated honestly.
I won't use this. Firstly, they offer only support for credit cards (which most German people don't have). And again, they want me to be full-aged:
(marked things: if I'm between 13 and 17 I'm allowed to use Google Wallet for Google Play Store only, if I'm at least 18 I'm allowed to use it for other purposes, too)
Question: How can I legally sell things / services on the internet as an under-aged person (when I'm allowed to sell things generally)?
