In order to maximise interoperability, electronic invoices should in principle comply with the European standard laid down in Commission Implementing Decision (EU) 2017/1870 (the European standard), which fulfils the request made by the Commission pursuant to Article 3(1) of Directive 2014/55/EU of the European Parliament and the Council to create a European standard for the semantic data model of the core elements of an electronic invoice. However, Member States should still be able to allow for other standards for domestic supplies.
