CEN/TC 434

CEN/TC 434 is a technical body within the European Committee for Standardization established in 2014 to develop standards in the field of electronic invoicing.

Overview

CEN/TC 434 has developed the European Standard on Electronic Invoicing and other ancillary standardization deliverables required by the European Union's directive on electronic invoicing in public procurement, Directive 2014/55/EU.
Directive 2014/55/EU also required:

the test of the standard as to its practical application for an end user,
a report on the outcome of the test to the European Parliament and the Council by the European Commission and, after the publication and the test of the standard,
the publication in the Official Journal of the European Union of a reference to the European Standard together with the list of a limited number of syntaxes.

The European E-Invoice Service Providers Association has played an active role in CEN/TC 434.
