Electronic Invoice

For relations between companies and public administrations


To send and receive invoices between companies and public administrations, we have developed the SP4i (Service Provider for e-invoices) invoicing engine, a service that helps to comply with the legal requirements of electronic invoicing. This service enables companies to invoice their contractors and European public administrations, inside and outside their country of origin, in compliance with the laws 25/2013 and 9/2017 on the requirements for electronic invoices.

The electronic invoicing service is already being used successfully in the Catalan Association of micro, small and medium-sized enterprises (PIMEC) and by more than 18,000 SMEs through the provider pimefactura.


  • Sending invoices in XML FACTURAe or PDF format: the invoice can be signed directly by the sender or within the service. Once loaded and confirmed, it is sent to the recipient via a general entry point (AAPP) or by e-mail with proof of delivery (for private companies).
  • The service allows users to track the processing status of the sent invoices.
  • Receiving invoices in XML FACTURAe or PDF format: between private companies as well as electronic invoices coming from general entry points of public administrations and the PEPPOL network of the European Union.
