e-Invoicing in Portugal
Characteristics of the electronic invoice in Portugal
The electronic invoice in Portugal is only regulated when invoicing public administrations, as decreed by the European Directive 2014/55/EU. All Portugues public entities will manage invoices electronically by the end of 2021.
The eSPAP is the entity in charge of the implementation of the electronic invoice as designated by the Ministry of Finance, Infrastructure, and Housing.
Suppliers to public administrations registered in eSPAP must register in the eSPAP platform and perform the pertinent tests. Suppliers of public entities not connected to eSPAP must directly connect with each public administration.
