Electronic invoicing will be mandatory for e-Procurement processes in Portugal


Portugal will make e-Invoicing with its public administrations mandatory from 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.

Electronic VAT and accounting systems in Portugal

EDICOM has been working for years with electronic models in Portugal regarding VAT declarations, electronic transport documents and now also with electronic accounting.

The electronic accounting model is the most recent. From July 1, 2018, systems must be able to record the necessary information in order to generate the accounting file. Companies must declare all accounting movements electronically to the tax authority in SAFT-PT format.

This statement may be monthly or yearly and the new SAF-PT accounting file must necessarily include the following control fields:

  • Article list
  • Client list
  • Suppliers list
  • VAT systems  
  • Accounting transactions
  • Accounts balance

The e-VAT return in SAF-PT format must be submitted by the 25th of each month. The authorities require invoices and delivery notes to be generated sequentially, and to also go through an encrypting process implementing an electronic signature, data related to the previous invoice and the file generation process control systems. EDICOM works on the Global VAT Compliance platform with many companies that have integrated and automated the declaration of this document with the tax authority.

For the process of declaration of electronic transport documents, the EDICOM solution automates the sending of data in real time through Webservice with the tax authority, which issues the authorization code. The solution automatically receives the code and includes it in the transport document. This code enables the movement of goods.
