The year 2026 marks a before and after in the administrative management of Spanish companies. What began as a legislative project with the Create and Grow Law, has today become an unavoidable reality: mandatory electronic invoicing in all operations between entrepreneurs and professionals (B2B). 🚀

At Ruiz & Associates, we understand that this change is not just a new accounting obligation, but a profound digital transformation. Our mission is to ensure that this transition is a step towards efficiency and not a source of penalties or operational bottlenecks.

⚖️ The legal framework: Create and Grow Law and the Verifactu system

The implementation of mandatory electronic invoicing aims to reduce late payments and digitize the business sector. But for businesses, this translates into very specific technical requirements. Invoicing systems can no longer be simple text editors; they must be certified and guarantee the integrity, preservation, and readability of the data. 🛡️

Furthermore, this system coexists with the Verifactu standard, which allows the Tax Agency to receive invoice information in real time. This interconnection is what powers the Tax Agency’s algorithmic audit that we recently analyzed, ensuring that any discrepancies are detected instantly.

📋 Requirements for issuing a mandatory electronic invoice

In order for their invoices to be legal in this new environment of 2026, they must comply with parameters that go beyond traditional content:

• Standard syntax: Invoices must be issued in structured formats (such as Facturae) that allow automated processing by the recipient.
• Free Interconnectivity: The law requires that technological solutions allow the sending and receiving of invoices at no additional cost to the customer.
• Retention period: Companies must maintain access to these electronic invoices for a period of 4 years, ensuring that the customer can consult them even if they are no longer subscribed to their services. 📂

The correct application of these points is vital to maintain the legal certainty of your business. You can consult the technical details of the regulation on the portal of the Ministry of Economic Affairs and Digital Transformation.

🔍 Payment control: The end of hidden delinquency

One of the main objectives of mandatory electronic invoicing is to control payment deadlines. The system now allows recording not only when the invoice is issued, but also when it is actually paid. ✅

Companies that fail to meet legal payment deadlines could be excluded from public subsidies and face problems with their tax risk indicators. At our firm, we help integrate tools like Holded or ContaSol (internal link) that automate this record-keeping, ensuring your company complies with the Late Payment Law without additional manual effort.

🤖 How to avoid mistakes in the digital transition

Implementing mandatory electronic invoicing at the last minute is a risk your treasury department shouldn’t take. Errors in formatting or submission can lead to invoices being rejected by your customers, delaying payments.

Thanks to the right to excuse errors, there is some flexibility regarding unintentional computer glitches during the first few months, but the tax authorities will be relentless with those who ignore the obligation to issue invoices in a structured digital format. Proactivity is, once again, your best strategy.
