In December 2003 Denmark legislated{{Cite web|url=http://www.oio.dk/XML/standardisering/eHandel/materialer/OIOXMLeInvoice|title=Danish statute for OIOXML eInvoice|website=www.oio.dk|access-date=2016-09-29}} the mandatory use of a customization of UBL 0.7, using the OIOXML specification, for electronic invoicing for government procurement starting February 2005. In March 2010 Denmark legislated{{Cite web|url=http://oioubl.info/documents/en/OIOUBLStatute.pdf|title=Executive Order on Information in, and Transport of, OIOUBL Electronic Invoices for Electronic Settlement with Public Authorities}} the mandatory use of a customization of UBL 2.0, using the [http://oioubl.info/classes/en/index.html OIOUBL] specification.

In 2011 the Danish government documented{{Cite web|url=https://www.oasis-open.org/committees/download.php/36397|title=E-Invoicing in Denmark}} savings of €500,000,000 having used UBL.

As part of the Northern European cooperation on e-commerce and e-procurement, representatives from Denmark, Sweden, Norway, Finland, UK and Iceland set up a working group for developing a Northern European subset of UBL 2.0 documents. The main focus of NES is to define the semantic use of UBL 2.0 as applied to specific business processes. To achieve this the UBL 2.0 standard is restricted on additional levels by using "profiles" that apply to defined business situations.{{cite web | url=http://www.unimaze.com/support/resources/on-nesubl | title=On NESUBL (an overview)| date=5 August 2020}} The use of individual elements is specifically described to avoid conflicting interpretation. Additionally each country has developed guidelines that describe the application of the NESUBL subset to domestic business practices. The goal is to enable companies and institutions to implement e-commerce by agreeing to a specific profile and thus eliminate the need for bilateral implementation. Additional countries have shown interest in joining the work. The NESUBL subset was published in March 2007.{{cite web | url=http://www.nesubl.eu | title=NES official homepage | access-date=2007-03-31 |archive-url = https://web.archive.org/web/20070320000433/http://www.nesubl.eu/ |archive-date = 2007-03-20}}

Since its publication, NESUBL subset has influenced government eProcurement initiatives across Europe, for example in Denmark, Sweden, Norway, Iceland, The Netherlands, Turkey. It is also the basis for an eProcurement initiative, {{Not a typo|ePrior}}, by the European Commission, Directorate General's of the European Commission, starting with the Directorate General for Information Technology (DIGIT).{{cite web | url=http://www.epractice.eu/cases/ePRIOR | title=IDABC e-Invoicing and e-Ordering project for public procurement, by Pieter Breyne | access-date=2010-04-03}}{{cite web|url=http://www.epractice.eu/en/library/288906|title=Analysis of Business Requirements for e-Invoicing in a Public Procurement Context : Final Study|last=Breyne|first=Pieter|author2=Philip Van Langenhove |author3=Joao Frade |author4=Maarten Daniëls |date=31 March 2009|publisher=European Commission|access-date=5 January 2012}} It is also the basis of the syntax for business documents created by the CEN/BII (Business Interoperability Initiative).{{cite web|url=http://spec.cenbii.eu/|title=The CEN / BII workshop results|access-date=2010-04-03}}{{cite web|url=http://www.cen.eu/cen/Sectors/Sectors/ISSS/Activity/Pages/Ws_BII.aspx|title=The CEN / BII official homepage|access-date=2010-04-03}}

The future of e-invoicing in Italy will facilitate the correct implementation of the national Technical Rules for Interoperability between e-Procurement platforms (Circolare 3 AgID) and the automation of the end-to-end procurement process, based on PEPPOL or, where a PEPPOL specification is not available, by implementing a CEN BII profile using the OASIS UBL 2.1 syntax.{{Cite web|url=https://ec.europa.eu/docsroom/documents/25521/attachments/1/translations/en/renditions/native|title=Study on the practical application and implementation of the European e-Invoicing standard}} In the long term, likely by 2022, the objective is to migrate to a single global standard, UBL, still supporting the other mandatory syntax with translations, and phasing out the national format.
