European e-Invoicing

e-Invoicing will be mandatory for e-Procurement in Portugal

e-Invoicing Portugal

Portugal will require the use of electronic invoicing in public procurement processes as of 2020.

The Public Administration Shared Services Entity, eSPAP, will be the coordinating body for the rollout of e-invoicing in Portugal.

The Decree-law that governs the e-Invoicing system was passed on 31 August 2017. This decree was modified by Decree 123/2018, published on December 28, 2018, in which the characteristics of the model and the new terms of obligation are defined.

EDICOM has a multi-standard and multiprotocol platform able to transform the invoices to the required format and forward the files through the communication protocol set by each invoicing platform.
