Editing Invoice (section)

===CEFACT and UBL===
{{update section|date=May 2019}}
There are two XML-based standards currently being developed. One is the cross industry invoice under development by the United Nations standards body [[UN/CEFACT]] and the other is [[Universal Business Language]] (UBL) which is issued by [[OASIS (organization)|Organization for the Advancement of Structured Information Standards]] (OASIS). Implementations of invoices based on UBL are common, most importantly in the public sector in [[Denmark]] as it was the first country where the use of UBL was mandated by law for all invoices in the public sector. Further implementations are underway in the Scandinavian countries as result of the North European Subset project. Implementations are also underway in [[Italy]], [[Spain]], and the [[Netherlands]] (UBL 2.0)<ref>{{cite web|url=http://www.rijksoverheid.nl/onderwerpen/digitale-overheid/elektronisch-factureren|title=Elektronisch factureren|publisher=[[Government of the Netherlands]]|language=nl|access-date=5 January 2012|url-status=dead|archive-url=https://web.archive.org/web/20111122221456/http://www.rijksoverheid.nl/onderwerpen/digitale-overheid/elektronisch-factureren|archive-date=22 November 2011|df=dmy-all}}</ref> and with the [[European Commission]] itself.

The NES work has been transferred to [[European Committee for Standardization]] (CEN), the standards body of the European Union), workshop CEN/BII, for public procurement in Europe. The result of that work is [[PEPPOL]]. There UBL procurement documents are implemented between various European countries.

An agreement was made between UBL and UN/CEFACT for convergence of the two XML messages standards with the objective of merging the two standards into one before end of 2009, including the provision of an upgrade path for implementations started in either standard.
