Extension for Verifactu: should I adapt or should I wait?

Right now almost all of us are focused on the Black Friday and Cyber Monday campaigns, as well as the imminent Christmas sales. It is still the typical thing in eCommerce when the fourth quarter of the year arrives.

What happens is that, once this final period is over, 2026 arrives, and it comes with some new developments and obligations for national companies and self-employed workers.

Among all of them, what stood out and caused particular concern was the famous Verifactu, associated with something as important as the issuance of your invoices, which I imagine you will already have heard a lot about by now.

Although the latest news inform of a new and unexpected extension of Verifactu until 2027, so it is no longer so urgent, but it will end up being mandatory all the same.

This post intends to give a brief overview of what Verifactu is, who is required to use it today and how to implement it in your business.

Get ready because here we go.

I will recap it quickly. Verifactu is the new billing assurance system from the Spanish government, that is, the sending and registration of invoices required by the Tax Agency to try to prevent and control tax fraud.

The objective is to ensure the integrity, traceability and accuracy of all invoices issued by companies and the self-employed.

In practice, it means that your billing software must generate files with a specific format validated by the Tax Agency, which is reliable and unalterable and that offers the option of sending the documentation directly to the Tax Agency (it is voluntary to do so for now, but the program must provide that alternative).

You do not necessarily have to change software, but you do have to ensure that you are operating with one that is approved, that does things in the proper way.

In short, it is what is called adapting to a technical standard to avoid incidents and tax fraud, but not a change that impacts your daily way of working.

Although the different billing softwares are required to be adapted and approved since last July 2025, the reality is that Verifactu is going to be mandatory from January 1, 2027 for all companies, public limited or limited, that pay corporation tax.

Do the self-employed have to adopt Verifactu? Indeed, self-employed workers also have to use an approved billing program, although in their case, there is a little more leeway, since the obligation starts a little later, specifically on July 1, 2027.

In short: all individuals and entities that carry out activities subject to invoice issuance must ensure that they use a program adapted to the new requirements of the Tax Agency, whether in January or July depending on what applies to them.

For all those who fail to comply with this rule after the implementation period, the law provides for fines and they are not small.

I do not want to scare you, but if you use a non-approved program, you face a possible penalty of up to 50,000 euros/year. This occurs even if there is no irregularity or fraud as such, and your accounts are as clean as a whistle.

As they say: it is no joke, certainly.

We have always seen ourselves as an ally for your business, rather than just a platform to create online stores. That is why we are always attentive to any development that may affect our clients, whether on a technical, strategic or management level.

We are facing one of the most important changes of recent years, which is why we wanted to assure you that, in 2027, all Oleoshop eCommerce stores will integrate perfectly with the main tools on the market. So… good news for users of Holded, Facturadirecta or StockAgile, because they will be able to work smoothly and safely with these softwares.

But we are not going to stop here; we have a project to keep adding more and more billing tools that guarantee compliance with the Verifactu standards. If your program is not among the initial list, you can let us know in this post so that we take it into account in that second phase. Although this extension gives us extra margin to reach more and more tools.

Do not see Verifactu as a problem; take it as a good opportunity to review your internal processes and modernise tools that perhaps had fallen behind. Adapting to Verifactu not only avoids penalties, but also improves administrative efficiency and tax transparency, something especially important for any company.
