Verifactu and your WooCommerce store: what changes and how to be ready for 2027
Verifactu now has firm dates, and 2026 is the year to lay the groundwork calmly. If you sell through WooCommerce and run your business on Factusol, it pays to get your flow ready now: migrating or adapting an invoicing system takes time and testing, and rushing at the last minute is always expensive. In this guide we cover what Verifactu is, who must comply and when, what’s expected of your software, and how it fits with your store.
What Verifactu is
Verifactu is the Spanish Tax Agency (AEAT) system tied to the regulation on invoicing software (RRSIF), approved by Royal Decree 1007/2023 and developed by Order HAC/1177/2024. Its goal is for invoicing programs to produce reliable, traceable records of every invoice, so they can’t be altered without leaving a trace.
In late 2025, Royal Decree-law 15/2025 (2 December 2025) pushed the obligation back by a year for businesses and the self-employed — which is exactly the runway we have now.
Who must comply, and from when
The dates confirmed by the AEAT are:
- 1 January 2027 for Corporate Income Tax payers (companies).
- 1 July 2027 for all other businesses and the self-employed.
Invoicing software vendors, in turn, had to have their systems adapted by 29 July 2025. In other words, the technology is ready before the obligation to use it kicks in — precisely so you have time to adopt it without stress.
Dates and scope can depend on your specific situation. Always confirm yours with the AEAT or your tax advisor before making decisions.
What your software needs to do
Without getting into the technical detail (worth checking with the AEAT), the regulation’s core aim is that your invoicing system guarantees four things about the records it creates: that they are tamper-proof, traceable (chained one to the next), preservable and legible for the authorities. In practice, that means using software that is ready for Verifactu and keeping it up to date.
The point isn’t to turn you into a regulation expert — it’s to choose tools that already account for these requirements and fit the way you work.
Getting your Factusol + WooCommerce flow ready
If your day-to-day is Factusol for back office and WooCommerce for selling, the sensible path is this:
- Centralise invoicing in your management system instead of issuing documents in several places.
- Keep store and back office in sync (products, prices, stock and orders), so the data that ends up on an invoice is correct from the start.
- Lean on software that’s ready for Verifactu, so adapting is an update, not a last-minute overhaul.
- Test with time to spare throughout 2026, free of deadline pressure.
This is where a solid link between your ERP and your store takes work off your plate: the cleaner and more automatic the data flow, the fewer surprises when the obligation takes effect.
Checklist to reach 2027 without a scramble
- Confirm with the AEAT or your advisor which date applies to you (1 Jan or 1 Jul 2027).
- Check that your invoicing software is ready for Verifactu.
- Unify invoice issuing in your management system.
- Make sure Factusol and WooCommerce stay in sync (stock, prices, orders).
- Block out time in 2026 to test the full end-to-end flow.
Takeaway
Verifactu isn’t a shock if you prepare ahead. With the 2027 dates on the table, 2026 is the moment to tidy up your invoicing and get your Factusol + WooCommerce flow in shape. If you want your back office and your store to speak the same language and arrive prepared, FactuOnline Woo is built for exactly that: it connects Factusol with WooCommerce and is ready to support you through the transition.
