Not a startup, but a small UK Ltd selling software services to a German company.

At the moment, selling to the EU just requires filling in VAT and EC Sales List tax forms. This paperwork is all automated by accounting software.

If selling from a UK Ltd company ever becomes a problem, it is a simple matter to create a company in an EU country so I can continue to sell services and products via that. Having residency isn't required to setup and run a company in many EU countries, so I suspect I'd be able to continue working without worry.

The only issue would be transferring over income from a foreign country in a compliant manner. If that becomes expensive, then it might be worth moving residency to a different country. But rushing to make a decision seems rather silly when the decision depends on details that haven't even been talked about yet.
