Shopify Payments is crucial for my business (ecom, dropshipping). Here is the list of supported countries: Shopify Payments requirements
Some will say Stripe is the same (true, the engine is the same) but Stripe hates dropshippers, it's actually against their T&C. I process ~100k /month with shopify payments and never had any issue. I once tried to switch to Stripe on one of my stores and got banned within a few days. There are other payment processors like Mollie but their are by far not as good as stripe/shopify payment since they don't even integrate in Shopify's checkout process.
Why the two companies though? Sounds like expensive overhead.
It's explained here:
US LLC are pass entity meaning all Revenues generated by them will flow on personal incomes. you are taxed as unlimited in Germany meaning that worldwide income has to be declared.
The Finanzmatt will be informed by IRS that you have an entity there ( Not the amount of cash but the entity) the Finanzmatt will then decide to pursue this indication and they will. It take just a second to extract all Germany residents info from database then send it to the Finanzmatt
As far as I know the US didn't sign CRS, why would they rat me out ? I now understand it's a bad idea and I will not do it but I am curious
