Why is it smart to adapt to Verifactu before the mandatory compliance date?
We know the Verifactu regulation brings a revolution in how electronic invoicing and fiscal control are handled in Spain. But beyond mere legal compliance, getting ahead of the enforcement dates (July 29, 2025 for software developers, January 2026 for companies, and July 2026 for freelancers) can make the difference between being ready… or gasping at the finish line. So why is it not only worth it, but actually smart to adapt early? Let’s break it down by profile:
🧑💻 Verifactu: Why should software developers adapt before July 29, 2025?
A real competitive advantage
If your software complies early with Verifactu, your current and future clients will meet the requirements stress-free, positioning you ahead of the competition. Clients look for peace of mind, compliance, and reliability, and they choose whoever can offer it first.
Industry-specific complexity: don’t leave loose ends
Some sectors require specific invoicing setups. Adapting your software in advance gives you the time to validate every detail and ensure your system handles all edge cases.

Yes, the AEAT’s announcement that any new invoicing software acquired from July 29, 2025 onwards must actively comply with Verifactu (even if your clients aren’t yet required to do so) surprised many. Our clients thought they had until July 2025, but weren’t expecting their systems to be tested so soon. That’s why fiskaly offers a free demo of the API, so both developers and companies can test and begin adapting.
No stress, no rush
Starting early means time to plan development, properly test integrations, and avoid last-minute bugs. Rushing leads to mistakes, especially with real-time data sent to tax authorities. Last-minute stress often comes at a high cost.
Avoid major fines
Speaking of costly mistakes… non-compliance with Verifactu as a developer can cost up to €150,000 per client and fiscal year. If your clients test your software early, you all gain in security and peace of mind. Especially important given the next point 👇
Verifactu: SMEs, freelancers, and franchises. Why adapt before 2026?
AEAT test period: take advantage of it
Although there was no planned test phase for taxpayers, the AEAT has confirmed that, until January 2026, businesses can send Verifactu files in real-time without being penalized for integration errors, as long as they are correctly identified and resolved. We’ve seen this in other countries: this is the best time to validate your processes without the risk of fines.
Avoid serious penalties
While your software provider is responsible for compliance, your business could still face hefty fines if your invoicing system doesn’t meet Verifactu’s technical requirements. From 2026, this could mean up to €50,000 per fiscal year. It’s not worth risking it just to delay a few months. A “low-cost” API could end up being very expensive. Our advice: choose a reliable, tax-compliant partner like fiskaly’s Verifactu API.
Compliance by sector
Some special tax regimes can’t be handled with a simple plug & play solution. You’ll need tools that address your sector’s specific needs and guide you through the entire process. Again, a trusted partner with fiscal expertise and technical support is essential.
Franchises and Verifactu: unified management without headaches
If you run a franchise, we know the rollout can be complex. Start early to ensure all locations comply before the mandatory date, when mistakes can still be corrected. You’ll prevent errors, guarantee consistency, and protect your brand reputation.
Real experience: why you shouldn’t wait until the last minute to comply with Verifactu
Our experience with similar regulations such as TicketBAI in the Basque Country or fiscalization laws in Germany and Austria shows a clear pattern: those who adapt early gain market share, peace of mind, and avoid costly surprises. Those who wait rush at the end, make mistakes, and often miss the deadline, resulting in fines. AEAT recommends adapting during the test period so everyone can fine-tune processes before there are economic consequences.
