e-Procurement processes in Portugal

Portugal will require public administrations to engage in e-Invoicing with their suppliers and service providers. 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.
