Can any national European company do business in all other member states?
<p>For example, could a limited liability company registered in a Baltic EU state offer services in Poland?</p>
<p>What I learn from the first comment to this question, this might depend for example on services nature.</p>
<p>So these should be online subscription services. But where to read such things, are these national regulation laws defining which companies types from what countries allow to do what?</p>

<p>Yes. A company from one member state may do business in any E.U. state so long as it complies with local law in the course of doing so.</p>
<p>For example, a Dutch company doing business in Germany must still pay German taxes and comply with German labor laws for its German employees. But, it doesn't have to form a German subsidiary to do business in Germany.</p>
