I am looking for a way to handle the VAT correctly for B2B use cases

[Marc32]

I want to open my shop in Germany and looking for a solution for the following process:

Private customers always have to pay German VAT
Companies located in Germany have to pay VAT
Companies located in the EU which provide a valied VAT number don't have to pay VAT
Companies in the rest of the world don't have to pay VAT

First of all it would be useful if a customer could choose between company and private. If he selects a EU country the VAT should be required.

I'm very new and already had a look to modules but I didn't find one which solves my problem. Would be great if someone has an idea.
