As of 18 April 2019, e-Invoicing will be the invoicing system required between government agencies and providers to create a competitive market that powers interoperability and trade between companies. The date may be extended to 18 April 2020 for regional organisations.
Directive 2014/55/EU regulates e-Invoicing in public procurement and is aimed at reducing the cross-border obstacles to trade arising from the coexistence of different national legal requirements and technical standards on e-Invoicing. Each EU Member State must draft its own transposition of the law to adapt the e-Invoicing model to its legislative framework.
The European Commission tasked the European Committee for Standardisation (CEN) with creating e-Invoicing standards to facilitate the adoption of electronic invoicing. The national formats used must be compatible with these standards.
