B2G electronic invoicing in Spain Why choose easyap?

Sep 23, 2025 | Electronic invoicing

Digitization has also changed the relationship between businesses and public administrations. In Spain, B2G (Business to Government) invoicing is mandatory for public sector suppliers, which has driven the adoption of secure and approved electronic invoicing . We are facing a change that is a matter of legal compliance. However, it is also an opportunity to optimize processes, gain efficiency, and ensure the traceability of your operations.

Let's take a look at what B2G invoicing is, which companies should use it, how it differs from B2B, and its advantages. But above all, discover why you should choose easyap as your technology partner and make the most of its benefits.

What is B2G invoicing?

By definition, B2G invoicing is the process by which a company issues and sends electronic invoices to public administrations. In Spain, all suppliers who invoice a public body must do so in this way, through FACe (General Entry Point for State Electronic Invoices) or equivalent platforms managed by autonomous communities and local councils.

Differences between B2B and B2G invoices

Likewise, it is important to distinguish the acronym B2G from other commonly used acronyms such as B2C and B2G:

  • B2B (Business to Business): invoicing between private companies.
  • B2C (Business to Consumer): billing to end consumers.
  • B2G (Business to Government): invoicing government agencies and public entities.

In any case, while B2G billing differs significantly from B2C, it is closely linked to B2B. We can see this in the table below, where we compare the two:

Feature B2B invoice B2G invoice
Recipient Private companies Public administrations
Legal obligation Only in some cases (depending on electronic invoicing regulations) Mandatory since 2015
Shipping platform Various electronic invoicing systems FACe or other public platforms
Technical requirements Various formats, as agreed between companies Facturae format and official validation
Level of control Flexible between parts High, with traceability and mandatory acceptance

Who should bill governments and administrations?

While it is already mandatory in Spain, B2G invoicing is also becoming increasingly common in Europe. However, we are pioneers, as the obligation of electronic invoicing in our country has been a reality for a decade and affects:

  • Any supplier of goods and services.
  • Large, medium, and small businesses.
  • Self-employed and individual professionals individuals.

In fact, any legal entity that works with public institutions must already invoice electronically. How? Using the Facturae format, and through the FACe system or the corresponding entry points.

Legal framework for B2G invoicing in Spain

Legally, this mandatory B2G electronic invoicing in Spain is governed by Law 25/2013. This promotes electronic invoicing and the creation of an accounting register of invoices for the public sector

From January 15, 2015, all invoices issued to the Public Administration must be sent in electronic format. Similarly, this legal framework pursues the following objectives:

  • More transparency in public payments.
  • Combating late payments in transactions with the Administration.
  • Facilitating the traceability of public spending.
  • Digitizing the company-government relationship, reducing management costs.

For the chief financial officer, this adaptation is not optional: those who do not comply with the law will have their invoices rejected and their payments delayed.

International trends in B2G invoicing

As we said, Spain is not an isolated case. You only need to look at other countries to see that B2G electronic invoicing is spreading throughout Europe. We can see this in several specific cases:

  • Italy was one of the first countries to establish a comprehensive electronic invoicing requirement, initially for B2G relationships and later for B2B, with FatturaPA.
  • France and Germany are also moving towards hybrid models with national platforms that centralize public billing.
  • For its part, the European Union promotes standardization through the PEPPOL (Pan-European Public Procurement OnLine) format.

These cases anticipate that, in the coming years, we will have a homogeneous electronic invoicing framework throughout Europe. This will benefit Spanish companies that are already adapted.

General benefits of B2G electronic invoicing

Although some view this legal obligation as a burden, B2G invoicing brings significant advantages. Benefits that go far beyond legal compliance:

  • Avoid penalties and invoice rejections.
  • Greater agility in invoice management and validation.
  • Fewer errors thanks to the use of standardized formats.
  • Cost savings on paper, printing, storage, and postage.
  • Full traceability with detailed tracking of the status of each invoice in real time.
  • Improved liquidity, which facilitates more predictable collection periods.

How to choose a B2G electronic invoicing provider

Even so, to take advantage of these general benefits, it is essential to choose the right tool and partner. If you are at that point, consider the following criteria when making your choice:

  1. Legal compliance: the software must be approved to work with FACe and standardized formats.
  2. Scalability: it also allows you to carry out your B2B and B2C invoicing, as well as any future legal obligations that may be approved.
  3. Integration: it should be compatible with your ERP, CRM, and other accounting systems you already work with.
  4. Security: it must have data encryption and comply with information protection regulations.
  5. Support and guidance: providing real-time technical assistance and training for your financial team.
  6. Cost and ROI: evaluate the medium-term savings against the initial investment for each software program.
