Es geht um die Plattform Gumroad auf dieser kann man E-Books Kurse und alles Mögliche an Digitalen Gütern verkaufen. Jetzt weiß ich nur nicht was ic hdabei beachten muss um hier in Deutschland niemanden zu verärgern.
Auf der Website steht:
"
When you sign up with Gumroad, you are agreeing in our Terms of Service that you are basically selling your products to us, and we are selling them on your behalf. We are the "merchant of record."

Therefore, when your customers buy a product on Gumroad, they are buying the product from Gumroad. As a result, we are responsible for VAT. You are not. The VAT that customers pay does not touch your account whatsoever. We pay it directly to The Office of the Revenue Commissioners in Limerick, Ireland.

Therefore, it does not matter what your business standing is - you might be a large business, a small business, a small entrepreneur. As far as the EU or the UK is concerned, you are not involved in the transaction that your customers make. They are dealing with Gumroad, and Gumroad has to charge VAT. 

To summarize, when Gumroad pays you, we are paying you directly for selling your product to us. If your attorney or accountant advises that you need to invoice us on a weekly basis for us paying you out, that's fine.

Wenn ich dem Text glauben kann zahle ich nur die Einkommenssteuer und brauche keine Umsatzsteuer zu zahlen ?!
Und was ist mit einem Gewerbe, brauche ich überhaupt zwingend eins in diesem Falle .. da im Endeffekt Gumroad als verkäufer agiert ?

Würde mich über eine Antwort freuen
