Code10 eInvoicing – eFactura B2B Spain

Last update 29/07/2024
Spanish B2B electronic invoice – Ley Crea y crece

In July 2017, Spain was among the first countries to implement automatic VAT reporting through the SII. Similarly, since 2015, there has been the Facturae standard for the exchange of B2G electronic invoices with public administrations. 

With law 18/2022 on Business Creation and Growth, also known as “Ley Crea y Crece” , Spain joins other EU countries (Italy, France, Poland…) and will implement electronic invoicing between companies (B2B invoicing). The purpose of this law is to improve the invoicing process and fight against tax fraud. 

Companies are faced with the challenge of preparing for the new invoicing model, which in many cases will require the adaptation of some of their processes. But, far from seeing it as a drawback, this change should be seen as an opportunity for modernization. There are clear benefits derived from the implementation of electronic invoicing processes, for example: 

Reduction of invoicing time and costs: through automation, the invoicing process is streamlined, and errors are avoided. 

Improved traceability of transactions with customers and suppliers: every transaction is secure and automatically recorded by both the invoice issuer and the tax authorities. This helps to reduce tax evasion and streamline payment management. 

Initially, the technical specification was to be ready 6 months after the approval of the law. However, at this moment, the process is still in the public consultation phase to collect contributions from the different stakeholders involved: companies, billing service providers or software companies among others, to prepare the technical regulation. 

Once the regulation is approved, companies must comply with the following schedule: 

– For companies subject to SII, whose turnover exceeds €8m per year, the implementation period is 1 year from the approval of the technical regulation.  

– The rest of the companies, whose turnover is less than €8m, will have 2 years to implement the process once the technical regulation is approved. At CODE10 we are following all the news about Spanish eInvoice and we will keep our customers informed of the latest developments at all times.

Update 20/06/2023

On 15/06/2023 the draft of the decree that develops the technical specification for B2B invoicing in Spain was released. The key points described by the decree are the following:

  • Regulates what should be understood as an electronic invoice between businesses and professionals, as well as aspects related to the structure for the electronic invoice message.
  • Regulates the obligation of private electronic invoicing platforms to accept interconnection requests made by any other private platform.
  • Creates the public electronic invoicing solution that will be managed by the State Tax Administration Agency.
  • Regulates the obligation to report on the time of effective payment of the invoices received while enabling the ways to do so. This obligation is modulated according to the size of the companies.
  • Establishes the requirements to operate as an electronic invoice exchange platform.

The full draft can be accessed  HERE (in Spanish)

However, we still need to wait for the final approval of the decree to know when this will be effective so, keep tuned to the latest news in our website and social media!


Update 06/06/2023

During last AUSAPE conference we could attend a session by José Borja, direcotr of the IT tax department of the spanish tax agency. He gave us the last status regarding the technical specification and helped clarify some of the open points still on the table.

First of all, we need to point out that July general elections in Spain add a point of uncertainty regarding timing. This can delay the process as it’s uncertain that the government would approve the regulation before the elections. However, there are some aspects that were clarified during the session: 

  1. The tax agency preference is that there’s a central platform to receive the invoices that can be complementary to the eInvoicing private platforms
  2. Payment reporting is a key of the new regulation so new functionalities will be released on that matter.
  3. XML format needs to be clarified discussions are from enhanced Facturae format to adopting standard defined by EU
