If you are a private electronic invoice service platform, an accounting software provider or a Public Administration that has developed its own software, to be able to adapt your systems and be able to send or receive invoices from the e-FACT service, you must either request membership of the service and subsequently make the necessary adaptations to your software.

Therefore, you must follow the following steps:

  1. Send the service integration form through this support request
  2. Make the adaptations to your software explained in the integration guide .

You have all the documentation (adhesion forms, guides, user manuals, value-added services, etc.) at the following link: Integration documentation in the e-FACT .

If you need any clarification regarding the integration, you have the technical support portal at your disposal, and if you have any questions you can send them to the technical support service by opening a request.
