Many organization have been sending electronic invoices for over decades, but new business requirements are emerging in Europe, Brazil, Mexico and other countries, which is changing the compliance requirements for the sending and receiving of e-Invoices.  eInvoicing is more about the validation of tax information (VAT), the identity of the sender through digital signatures and the long term archiving and retrieval of the original document.

In some countries the requirements include ongoing reporting and trading partner contracts, which need to be managed on an ongoing basis.  So while EDI creates an electronic invoice, additional legal and technical requirements exist to be compliant.
