I'm pretty much always traveling, so I don't have a fixed residency. My parents own two apartments in two different parts of the world and I also have a large family spread across the world who I frequently visit - usually not staying in a country longer than 2 months. I'm 19 years old, EU-Citizen and developed a SaaS app which scaled rapidly to about 7k/mo revenue in about 6 months. I ran the whole thing illegally, which was pretty stupid I know - hence I took it offline while I decide how to structure the business/accounting side of things and also rewrite the code to be more scalable/automated. My questions are:
In which country should I form the company? Ultimately I want it to be fast and simple (aka electronic), countries like the UK and Singapore have all-online and quick company formation.
What's the best way to automate accounting? I was looking at xero.com as they provide an API which I can use to automate customer invoices and handle payment processor receipts - which brings me to my next problem, how am I supposed to open a business bank account without a real proof of address/residency?
Where am I supposed to pay my personal taxes?
