Article 226a Directive 2006/112/EC

Where the invoice is issued by a taxable person, who is not established in the Member State where the tax is due or whose establishment in that Member State does not intervene in the supply within the meaning of Article 192a, and who is making a supply of goods or services to a customer who is liable for payment of VAT, the taxable person may omit the details referred to in points (8), (9) and (10) of Article 226 and instead indicate, by reference to the quantity or extent of the goods or services supplied and their nature, the taxable amount of those goods or services.
