10. CORE Invoice Guide - Background
• The final report of the Expert Group on e-Invoicing proposes a European
Electronic Invoicing Framework (EEIF) as called for in the Terms of
Reference created by the European Commission when the Group was
established in late 2007. The EEIF is expected to establish a common
conceptual structure, including business requirements and standard(s),
and propose solutions supporting the provision of e-invoicing services in
an open and interoperable manner across Europe.
• In its end-2009 final report, the Expert Group (EG) recommends that all
actors adopt a common invoice content standard and data model based
on the UN/CEFACT Cross-Industry Invoice. The EG also recommends
development of a reference semantic data model to clarify the European
context, in particular to ensure that those implementing this technical
solution in Europe will be able to use it in a correct context.
