Totally new here so please forgive any etiquette omissions or mistakes. I am looking for links rather than specific advice if possible. My company trades with a lot of countries both EU and non EU. Almost all of these trades consists of buying from one country and selling to another country. My question is this, is there a link [or links] to any information site(s) for "foreign" companies trading internally within an EU member state. For example a UK company buying and selling within Germany, or a Netherlands company buying & selling within France. I suspect for example that in some, perhaps all EU member states, there is a limit [value] to the level of trade a "foreign" company can do within that member state before it may have to register, possibly as a foreign company trading with its borders, or perhaps having to register as a company within that country itself. A supplementary question to this is does it make a difference if the goods are delivered to another EU member state, i.e. [using the examples above] a UK company buying and selling with Germany but delivering the goods from Germany to Italy, or a Netherlands company buying and selling within France but delivering the goods to Belgium. Any suggested links would be very welcome, this event hasn't actually happened yet but I suspect it is only a matter of time!
