eInvoicing

CII

You can use CII to create message syntax, which are exchanged globally between trading partners. It was developed in UN/CEFACT with input from many business organizations.

CIUS-PT

In Portugal, electronic invoicing in public administration known as B2G e-invoicing is similar to existing models in other European countries. The coordinating body for the implementation of e-invoicing in Portugal is Entidade de Serviços Partilhados da Administração Pública (eSPAP).

UBL 2.1 CIUS-PT and CEFACT CIUS-PT are accepted and required as format for electronic signed invoices to public administrations.

Entities that use the Technical Standard UBL2.1 eSPap must transition to the new Technical Standard CIUS-PT. Both standards are expected to coexist in order to ensure the stability of existing processes and accommodate migration.

GS1

In Portugal, tax authorities require resident businesses that offer products or services to government bodies to issue an electronic invoice.

GS1 standards create a common foundation for business by uniquely identifying, accurately capturing, and automatically sharing vital information about products, locations, assets, and more. Businesses can also combine different GS1 standards to streamline business processes such as traceability.

PEPPOL

All European public administrations must support accepting invoices in electronic format from their suppliers, in compliance with the European standards approved by CEN: UN/CEFACT XML and UBL. Some countries have created their own national platforms to centralize the receipt of invoices from suppliers and others have opted to use the European PEPPOL network in preference for these B2G exchanges.

These standards are available for these invoices:

  • PEPPOL BIS, based on the UBL standard
  • CII, the UN/CEFACT XML

You can create invoices and credit notes based on these standards according to the country specifications of the destination country.

The LSP Web Services Gateway provides connectivity to Access Point Providers (APP) through the PEPPOL Access Point. Registration for multitenant cloud deployments is through LSP.
