¿Qué es la Digitalización contable?

In recent months, at GR International Advisors, we have been receiving an increasing number of enquiries from clients in Barcelona asking us the same question: «Is it true that I am required to digitalise my accounting?» The short answer is yes. The longer answer is what we want to explain in this article.

What does accounting digitalisation actually mean?

Digitalising your accounting does not mean scanning your invoices as PDFs or entering your figures into an Excel spreadsheet. At its core, that is still a manual process with a digital layer.

Digitalising your accounting means replacing these manual processes with a system that:

• Automatically records and classifies your transactions.
• Issues and receives invoices in electronic format, rather than on paper or as standalone PDFs.
• Calculates taxes and generates accounting entries without manual intervention.
• Connects directly with your bank, Social Security and the Spanish Tax Agency.
• Gives you access to your financial data in real time, rather than only at the end of the month.

The distinction matters because Spanish law does not require you to «have your invoices stored on your computer». It requires a specific system with specific technical features. This is where many SMEs make a mistake: they believe they are already digitalised because they use a spreadsheet, when in reality they remain exposed to many of the same risks as if they were keeping their books on paper.

Why is it no longer optional?

Until a few years ago, digitalising your accounting was an efficiency decision: you did it if you wanted to save time or reduce errors. Today, it is a legal requirement. Three regulations have made it mandatory, and it is important to distinguish between them because each one regulates a different aspect.

1. The Anti-Fraud Law (Law 11/2021)

This law requires the accounting and invoicing software used by your company to be certified and comply with specific technical requirements: it must record all transactions, must not allow data to be deleted or modified without leaving a trace, and must comply with the standards established by the Spanish Tax Agency.

In practice, this means that many «home-made» accounting systems or systems built using spreadsheets and macros are no longer legally compliant for keeping a company’s accounts, even if they work perfectly well from an operational perspective.

2. The Create and Grow Law

This is the regulation that generates the most questions. It establishes that companies and self-employed professionals will have to issue and receive invoices in electronic format, rather than as PDFs or on paper. This involves:

• Using software compatible with Facturae or other equivalent structured formats.
• Storing invoices digitally for a minimum of 4 years, with guarantees of integrity.
• Being able to communicate, directly or indirectly, with the Spanish Tax Agency’s systems.

The implementation timetable is being phased in according to your company’s turnover, and it is being adjusted as the technical deployment of the system progresses. This is why, at GR, we review each client’s situation individually to determine the exact deadline that applies to them rather than providing a generic date.

3. Verifactu

Verifactu is the system through which the Spanish Tax Agency verifies, almost in real time, that the invoices issued by your company match those it reports. It is the component that connects your invoicing software directly with the Spanish Tax Agency, and its implementation is being phased in between 2026 and 2027 depending on the type and size of the company.

These three regulations are not alternatives to one another: they apply in parallel. A business may already comply with the Anti-Fraud Law by using certified software, but still fail to comply with the Create and Grow Law because it continues to send invoices as PDFs by email. They are different layers of the same underlying change.

What happens if you do not adapt in time?

Failing to comply with these obligations is not just a theoretical risk. The most common consequences we see in practice are:

• Financial penalties from the Spanish Tax Agency, both for using non-certified software and for failing to meet electronic invoicing deadlines.
• Operational problems, because once the system is active for your type of company, invoices that do not comply with the correct format may not be properly recognised by your customers or suppliers.
• Avoidable loss of time, because companies that leave digitalisation until the last minute often have to migrate in a rush, without proper planning, and end up duplicating work.

The good news is that none of these three regulations requires a radical change overnight if you start with enough time. The problem arises when the process is treated as a last-minute emergency.

The benefits go beyond legal compliance

Although the legal framework is what is currently pushing many companies to take this step, accounting digitalisation offers benefits that go beyond avoiding penalties:

Fewer errors and less wasted time. Automating tasks such as bank reconciliation or expense classification eliminates many of the human errors that occur with manual processes and frees up hours currently spent entering data by hand.

Real-time financial visibility. Being able to check the status of your income, expenses and taxes at any time, rather than only at the end of the month, changes how decisions are made. It means being able to anticipate a cash flow problem rather than simply reacting to it.

Less paper, lower costs, less space. Reducing physical filing, printers and trips to deliver documents has a direct impact on operating costs, as well as on sustainability.

A smoother relationship with your accounting firm. When your accounting software is connected to your accountant’s system, there is no need to exchange folders of documents every quarter. Your accountant can access what they need directly, review your accounts and file your taxes more efficiently. This is, in fact, where we notice the biggest difference with clients who still work manually: the time previously spent collecting and sending documents can instead be used to discuss actual tax strategy.

How we approach it at GR

We work with companies in Barcelona that are at very different stages of this process, from businesses that still issue paper invoices to those that already have an ERP but need to adapt it to Verifactu. That is why we do not offer a one-size-fits-all package. We always start with an initial audit to establish exactly what you have in place today, which legal deadlines apply to you and what is the minimum you need to comply without burdening yourself with tools you will not use.

From there, we take care of the technical side, including digital certificates, invoice OCR, automated bank reconciliation and document management, so you do not have to become an expert in digital tax regulations. That is what we are here for.

In summary

Accounting digitalisation in Spain is no longer an optional operational improvement. It is a legal requirement being introduced through several different layers, including the Anti-Fraud Law, the Create and Grow Law and Verifactu, with different deadlines depending on the type of company. The sooner you start adapting, the more time you will have to do it properly and the lower the cost is likely to be.

If you do not know which deadlines apply specifically to your business, that is the first point we address during the initial audit.
