Facturae eInvoicing

Proprietary format	Reference
Facturae	3.2.2

Facturae is the electronic invoice format for the General State Administration that was set out in Order PRE/2971/2007 for the issuing of invoices by electronic means when their addressee is the General State Administration and for filing invoices issued between private individuals with the General State Administration. Filling with and addressing General State Administrator includes public organizations linked to or dependent on the administrator.

An electronic signature is needed to guarantee the authenticity and integrity of the e-invoice, providing more security than paper invoices. The file to be sent to the customer contains both the invoice information and an embedded signature.
