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 23,000 SMEs through the provider pimefactura.
