US-based production is just the easiest for me to get off the ground initially. If we can eventually be more tax efficient for EU users by producing elsewhere as well, I'm definitely open to that. But then I'm guessing it would need to go from production directly to the user without leaving the EU, i.e. it would be impossible for me to test the hardware in person. EU people feel free to message me if you have advice or ideas on this. The design itself is portable. We could easily have it made in multiple facilities. But does that help us avoid EU tax if the company having the production done is based in the US?
In my experience it can be logistically challenging to do production in China, so I'd rather avoid it unless there is some clear tax benefit.
Another idea would be to have someone working for me based in the EU receive EU-produced orders, test and send out to EU users. But that adds a lot of complexity. I might be able to convince Philip to help out with that eventually; he's based in Hamburg. Maybe there's a possible loophole there if I "hire" someone from the EU but the actual production still happens in the US.
I'll look into it more.
