Over 190 countries are now using the OASIS Universal Business Language (UBL) for e-invoicing. Denmark was the first country to legislate it's use in 2005 for invoicing the Danish govt. Subsequently the EU, Latin America and many other countries followed this initiative. Canada has been somewhat slow on any activity involving the implementation of this Global Open standard. This presentation has been given at PDW 2013, and the Ottawa PC Users Group. The http://goUBL.com business ecosystem has been established to promote the use of the OASIS UBL in North America.
