Even though the EU is one market, it really isn't much of a single market due to language and cultural differences. I've helped B2B companies and most small/medium sized ones want to limit their services to their own (and their country's neighbor's) country. There are a ton of problems related to fake company addresses placing orders and having them delivered at some random company's parking lot. Problems with regards to refunds, and –mot important– it is VERY hard to get the police to do anything about it. The minute it is outside of their jurisdiction, the police just doesn't do anything really.
