Article 224
1. Invoices may be drawn up by the customer in respect of the supply to him, by a taxable person, of goods or services, if there is a prior agreement between the two parties and provided that a procedure exists for the acceptance of each invoice by the taxable person supplying the goods or services. 2. The Member States in whose territory the goods or services are supplied shall determine the terms and conditions of such prior agreements and of the acceptance procedures between the taxable person and the customer. 3. Member States may impose further conditions on taxable persons supplying goods or services in their territory concerning the issue of invoices by the customer. They may, in particular, require that such invoices be issued in the name and on behalf of the taxable person. The conditions referred to in the first subparagraph must always be the same wherever the customer is established.
