You can send your invoices to any entity in the public sector in Catalonia through the invoice delivery box , whether at the municipal, supramunicipal, public universities or the Generalitat de Catalunya level.

In the case of public sector organizations of the Generalitat, you can consult the entities, public companies and centers of the Generalitat prepared to receive electronic invoices .

How can an electronic invoice be created?

There are a series of free solutions that allow the creation of invoices that can subsequently be sent to Catalan Public Administrations that have the e-FACT service (General Entry Point for Electronic Invoices in the public sector of Catalonia).

From AOC we offer you a free tool to create invoices from the General Electronic Invoice Entry Point itself. You can consult How to create invoices from the General Electronic Invoice Entry Point .

Currently the affiliated platforms are the following:

What format should the e-invoice have?

The electronic invoice format defined by the General State Administration and implemented in the e-FACT service of the AOC, is an XML with a structure known as Facturae.

Currently, the versions of Facturae accepted by the e-FACT service, in accordance with Law 25/2013, of December 27, on the promotion of electronic invoicing and creation of the accounting register of invoices in the Public Sector , are 3.2 and 3.2.1.

If you send invoices in an older format, they will be rejected.

You can obtain more details about the format scheme and versions on the page: http://www.facturae.es .

Why the XML format?

The invoice format is defined by the General State Administration. The fact that it is requested in XML format is because it is considered a structured format that contains data and can be automatically generated by the billing computer systems of both the issuer and the recipient. On the other hand, PDF is an unstructured format that consists of an image and involves manual intervention or a costly process. The facturae format only accepts XML.

NOTE : free solutions for creating invoices (B2B Router, Pimefectura...) will help you generate invoices in this format quickly.

And... what if I make few invoices?

If you are a small company or a supplier and you make invoices on a regular basis, or you have to make few invoices, some banks can handle it for you for free or for a small amount.

You can also do it through free solutions : B2B Router, Pimefactura or Billage

And... what if I make a lot of invoices?

Depending on the volume of invoices issued each month to Public Administrations (given that the obligation is only, for the time being, to invoice electronically to this type of organization), each company or organization can decide whether to integrate its electronic invoicing tool with the e-FACT service, assessing whether the investment in the integration is profitable compared to other mechanisms for the creation and delivery of electronic invoices (such as B2B Router, Pimefactura or Billage ).

From AOC, we recommend this integration, starting from 100 monthly invoices, given the complexity of this process. However, other variables may also play a role in the decision, such as the company's desire to simplify invoicing (converting it all to electronic), a diverse Public Administration client portfolio (adhering to different general points of entry for electronic invoices), or other organizational issues related to it.

You have the documentation and application form for integration into e-FACT for suppliers at How to integrate into e-FACT?

The administrations that adhere to the e-FACT service offer a delivery box that allows you to check the status of your invoice.

What certificates can I use to sign the invoice?

There are different digital certificate profiles valid for electronic signature of the invoice:

  • Qualified certificates for natural person legal representative: allows the holder to act on behalf of the entity or organization to which they belong.
  • Individual certificates: applicable for self-employed people and professionals, as is the case with the electronic DNI.
  • Qualified Electronic Seal Certificate : The electronic seal certificate allows the automated authentication and electronic signature of entities and companies and other legal persons, without human intervention. It does not contain representative data and is designed for automatic processes.

Information about qualified certificate providers : " Certificates accepted by the Validador of the AOC Consortium "

IMPORTANT : If you have any questions about how to sign the invoice , you should contact the support of the invoice creation program you use.
