CEN/TC 434

CEN/TC 434 (CEN Technical Committee 434) is a technical body within the European Committee for Standardization (CEN) established in 2014^[1] to develop standards in the field of electronic invoicing.^[2][3]

Overview

CEN/TC 434 has developed the European Standard on Electronic Invoicing (EN 16931-1) and other ancillary standardization deliverables^[4] required by the European Union's directive on electronic invoicing in public procurement, Directive 2014/55/EU.^[5]

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^[6] 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^[7] (that CEN published as TS 16931-2).

Workgroups

CEN/TC 434 has the following working groups (WGs):

• CEN/TC 434/WG 1 Core semantic data model
• CEN/TC 434/WG 3 Syntax bindings
• CEN/TC 434/WG 4 Guidelines at transmission level
• CEN/TC 434/WG 5 Extension methodology
• CEN/TC 434/WG 6 Test methodology and test results
• CEN/TC 434/WG 7 Registry Services

CEN/TC 434/WG 2 (List of syntaxes) was disbanded.
