This marks a major step toward reducing late payments, improving transparency in payment practices between businesses, and digitizing business transactions across the country.
In this article, you will find a summary of the key latest updates, a revised B2B e-invoicing rollout plan, and 10 essential facts to help you understand Spain's evolving e-invoicing law. Please note that the information provided here reflects the approved Royal Decree under the Crea y Crece Law, as well as the current regulatory framework. Certain technical specifications and implementation details may continue to be clarified following its publication in the Official State Gazette (BOE-A-2026-7295).
Latest key updates
Here are the most recent confirmed updates to Spain's e-invoicing regulations under the Crea y Crece Law:
UBL replaces Facturae: UBL (Universal Business Language) will now be the required format for Spain’s public invoicing system, replacing Facturae.
Payment term clarifications: Clarifications have been provided regarding payment terms for credit and debit notes, including start and end dates.
12-month notice period confirmed: A 12-month notice period has been confirmed, meaning implementation will begin 12 months after publication in the BOE.
On a somewhat related note, and addressing broader invoicing compliance, invoices created on the public platform will also be VERI*FACTU compliant. This requirement does not stem from the 'Create and Grow Law' but rather from the Anti-Fraud Law. (See below for further information about VERI*FACTU)
Create and Grow Law
The Royal Decree was approved on March 24, 2026, and following its publication in the Official State Gazette (BOE-A-2026-7295), implementation will follow a phased approach:
12 months after publication in the Official State Gazette (BOE): Large businesses (turnover > € 8M).
24 months after publication in the Official State Gazette (BOE): SMEs and all other taxpayers.
10 essential facts about Spain's B2B e-invoicing law, “Create and Grow”
We have put together the top 10 points to help you understand Spain's law (Crea y Crece Law), from key dates to invoice formats and compliance requirements, based on the approved Royal Decree and current regulatory framework. These points reflect the Royal Decree as published in the Official State Gazette (BOE-A-2026-7295).
1. Date of entry into force
Implementation is phased following the regulation's adoption as follows:
12 months after publication in the BOE: Obligation for companies and professionals with a turnover above € 8 million.
24 months after publication in the BOE: Obligation for companies and professionals with a turnover below € 8 million.
The turnover period considered will be that of the year prior to the entry into force of the obligation.
2. Scope of the law
Who will the law affect, and which businesses are in scope?
Domestic.
B2B, private companies, and professionals.
Does not affect FACe (B2G).
Public companies and UTEs (Unión Transitoria de Empresas) are subject to the law in the same way as private companies.
3. Communication of mandatory invoice statuses
What updates to invoice statuses must be reported?
Mandatory statuses include the commercial acceptance or rejection of the invoice and its date, as well as the full effective payment and its date.
Businesses must notify these statuses within 4 calendar days from the date of the notification of the status.
This requirement aims to provide benefits such as reduced late payments, improved invoice tracking, and greater transparency in business relationships.
By law, the maximum payment period is 60 days.
4. Signature
The rules concerning electronic signatures are as follows:
The invoice issuer must either sign the invoices, or:
They may choose to delegate the certificate to their e-invoicing service provider.
5. PDF
PDF invoices can fall into various categories, depending on a country’s invoice acceptance factors. Take a look at how the Spanish government will deal with PDF invoices within its B2B regulations.
Invoices in PDF format will continue to be accepted until the law becomes mandatory for businesses and professionals of all sizes.
Companies falling in the first wave of the obligation must issue invoices in electronic and PDF formats. They should be capable of receiving invoices in both formats.
Companies not in the first wave can keep their current invoice issuing methods until their obligation date, but they may issue electronically voluntarily.
6. Formats
It is vital to understand which electronic invoicing formats will be accepted within the regulations. A key change introduced in the regulation is the transition from Facturae to UBL (Universal Business Language), aligning Spain with the European Union standard EN 16931 and future initiatives such as VAT in the Digital Age (ViDA).
Public solution: UBL (Universal Business Language).
Private solutions: The billing platforms, solutions, or systems used by electronic invoice issuers will be required to send the true copy to the public electronic invoicing solution in UBL format. Other formats may be used for private exchanges, but UBL is mandatory for communication with the public platform.
7. Public platform
Many governments around the globe utilise a public/government platform within their B2G and B2B regulations.
Minimal solution for issuing invoices to suppliers and accessing customer invoices. Explicitly, it will not transmit the invoices, but only make them available for receivers. It will act as a central element of the system, enabling invoice traceability, status reporting, and greater transparency across business transactions.
A copy of the invoice must be sent to the public platform, and the invoice statuses (acceptance and effective payment) must be communicated.
8. SII (Suministro Inmediato de Información)
E-reporting to the SII will continue to work as before.
E-invoicing and e-reporting are two separate processes running in parallel.
9. Sanctions and control
No penalties regime is foreseen for the time being.
The State Observatory on Private Delinquency (Observatorio Estatal de la Morosidad Privada) will be responsible for monitoring the evolution of payment data and promoting good practices.
The publication of an annual list of non-compliant and late-paying companies (legal entities that fail to pay more than 5% of their invoices on time and whose total amount of unpaid invoices exceeds € 600,000) is envisaged.
10. International invoicing
There is no specific regulation at the international level, but at the European level, project ViDA (VAT in the Digital Age), which includes provisions for intra-Community e-invoicing and e-reporting requirements, is planned to take effect in July 2030.

While these ten points cover the core of the upcoming B2B e-invoicing mandate, it's also crucial to understand two other related regulatory systems impacting invoicing in Spain: VERI*FACTU and TicketBAI.
What is VERI*FACTU?
VERI*FACTU, a Regulation governing the requirements for Billing Computer Systems (RRSIF), is a method for complying with Spanish legislation on computerised billing systems. It guarantees the integrity, conservation, accessibility, legibility, traceability and immutability of billing records.
Most businesses and self-employed professionals in Spain that are subject to Personal Income Tax or Corporate Income Tax will be required to use invoicing systems that comply with the technical requirements for both full and simplified invoices. Although the initial effective date was set for 1 January 2026, Royal Decree-law 15/2025 has extended the adaptation deadlines as follows:
Until 1 January 2027 for companies (taxpayers under Article 3.1.a).
Until 1 July 2027 for self-employed professionals and freelancers (the remaining taxpayers under Article 3.1).
Businesses already reporting through the Immediate Supply of Information (SII) system, as well as those benefiting from specific exemptions, are not required to apply these new rules.
Invoices generated via the public platform will automatically meet VERI*FACTU requirements, simplifying compliance for businesses.
What is TicketBAI?
TicketBAI, a system introduced by the Basque Country's Foral Tax Authorities, requires businesses to send and certify invoices for all economic activities. Developed in collaboration with the three Foral Treasuries and the Basque Government, TicketBAI establishes specific legal and technical obligations for billing software.
The system aims to control income from economic activities, particularly those involving transactions with final consumers. In order to adhere to TicketBAI regulations, which came into effect in regions such as Bizkaia on 1 January 2024, businesses must use compliant software such as Banqup. TicketBAI ensures the integrity and traceability of billing records by requiring specific data to be submitted to the tax authorities.
What businesses should do now
With the approval of the regulation, businesses should start preparing for the transition to mandatory electronic invoicing:
Review current invoicing systems and processes,
Ensure readiness for UBL format,
Prepare to send and receive invoice status updates,
Evaluate technology providers to ensure compliance.
Taking early action will help businesses avoid disruption and ensure a smooth transition once the obligations come into force.
