“Not all software is suitable”: how to choose a system compatible with VeriFactu

Your invoicing software can be your best defense or your greatest risk. In 2026, choosing well will be a strategic, not a technological, decision.

The new filter: only programs with a proven track record will survive

Royal Decree 1007/2023 established the rules of the game: only systems that guarantee integrity, traceability, and unalterable data recording may be used. From July 2025, selling or using uncertified software may result in penalties of up to €50,000 per fiscal year. And not just any update will do.

Many companies believe that it will be enough for their provider to “send them a patch.” No. VeriFactu requires a certifiable architecture, not a new button. The system must generate each invoice with a unique identifier, a chained hash, and a verifiable QR code.

Checklist for choosing correctly

• Explicit certification: the supplier must declare compliance with the SIF Regulation and the VeriFactu format.
• Integration with the Spanish Tax Agency (AEAT): option for automatic record submission or internal storage capability.
• Full traceability: record of cancellations, corrections, and access.
• Internal audit: export of logs verifiable during inspections.
• Real support: technical support and automatic updates when the standard changes.

You get what you pay for

Choosing based on price will be a mistake. "Quick" or "homemade" programs won't offer a hash chain or legal compliance. And when the tax authorities audit, an invoice issued with a non-certified system will be worth as much as a crumpled piece of paper: nothing. "In 2026, you won't be penalized for misusing software; you'll be penalized for not choosing wisely."
