VeriFactu Invoicing Software 2027: 21 Programs Compared (Dual vs VeriFactu-Only)
With the obligation to adapt invoicing systems to RD 1007/2023 just around the corner (1 January 2027 for corporations, 1 July 2027 for freelancers), choosing the right software is no longer just a question of price or features: it is a decision that will shape how you interact with the Spanish Tax Agency for years to come. And one of the key questions is: does the program I am evaluating support only VeriFactu, only No-VeriFactu, or both modes?
VeriFactu-only, dual or non-compliant: what the AEAT says
Before getting into the comparison, it is worth understanding a distinction that the Tax Agency itself draws in its official FAQ. According to the AEAT, invoicing information systems (SIF) on the market can be of two types:
- VeriFactu-only: systems that only allow operation in VeriFactu mode, with automatic submission of records to the AEAT.
- Dual: systems that let the user choose between VeriFactu and No-VeriFactu (non-verifiable invoice issuance system). It is the customer who decides the operating mode.
This matters because not all programs on the market offer the same flexibility. Some force you to send your records to the tax authorities in real time with no option to choose No-VeriFactu mode; others give you the ability to choose based on your business needs.
Is there an official list of approved software? No. The AEAT does not certify or publish an official list of authorised programs. It is the manufacturers themselves who must guarantee compliance through a Responsible Declaration, which must be visible in the software and updated with each version. What you should ask your provider for is that declaration — not a supposed "approval" that does not exist.
Invoicing software comparison table
The following table lists the main invoicing programs available on the Spanish market as of April 2026, organised by mode: dual systems first (those that respect the choice the law grants to taxpayers), then VeriFactu-only, and finally non-compliant tools. The information has been obtained from each product's official pages and their public statements on RRSIF adaptation.

If the law offers two options, your software should offer both
There is a fact that often goes unnoticed in this debate: RD 1007/2023 expressly recognises two legal operating modes — VeriFactu and No-VeriFactu — and leaves the choice in the hands of the taxpayer. This is not a matter of complying more or less; both modes are equally valid and regulated in equal detail. The AEAT itself confirms this in its FAQ by distinguishing between "VeriFactu-only" and "dual" SIFs.
Yet when you look at the market, most invoicing programs only offer VeriFactu. Of the 21 systems covered in this comparison, only 7 are dual. The rest have chosen to implement only the automatic submission mode, effectively eliminating an option that the law grants to taxpayers.
Why does this happen? Because developing a dual system is technically more demanding: it requires implementing both the AEAT submission layer and the local electronic signature, event log and immutable custody layer. And because the AEAT, understandably, encourages the use of VeriFactu — a system where the tax authorities receive all information in real time is more convenient for fiscal control.
What is the problem? Software that only offers VeriFactu takes away from the taxpayer a decision that the law recognises as theirs. And that decision is not trivial:
- With VeriFactu, the tax authorities have immediate visibility of all your transactions and can act in real time — for example, by issuing credit seizure notifications on invoices just registered if there are outstanding tax debts.
- With No-VeriFactu, the tax authorities have no visibility of those transactions until the company files Form 347 in February of the following fiscal year, or until they formally request the records as part of an audit or inspection.
These are real implications for the taxpayer's relationship with the tax authorities, and it should be the taxpayer and their tax adviser who decide — not the software provider by default.
Dual-mode software is not a luxury; it is respect for the taxpayer's right to choose. If your invoicing program only allows VeriFactu, it is not because the law requires it — it is because the manufacturer decided not to implement the other option. And that, at the very least, is something you should consider before signing up.
Analysis by category
Dual software (VeriFactu and No-VeriFactu)
These are the most flexible and the ones that respect the choice the law grants to taxpayers. They allow the user to choose the operating mode and, in some cases, to switch from one to the other (with the restriction that, once VeriFactu is activated, the option remains in effect at least until 31 December of the year in which the first submission was made).
Holded is one of the best known in this category. In its settings panel (Compliance > Invoicing) it allows you to select "Yes VeriFactu", "No VeriFactu" or "Exempt". Once VeriFactu is activated, approved invoices are locked and sent with a verifiable QR. If No-VeriFactu is chosen, the system still guarantees integrity and immutability but does not perform automatic submission.
Sage 50, with its hybrid desktop + cloud model, also offers dual configuration. It is particularly strong in environments where accounting precision and fiscal depth are priorities: accountancy firms, retail with complex inventory, multi-activity businesses.
Wolters Kluwer (a3) offers dual mode with a clear settings screen where the user indicates whether they want to send records via VeriFactu or not. If No-VeriFactu is chosen, the system generates signed records and an exportable event log for any request from the tax authorities. It includes a Responsible Declaration and is especially popular among accountancy firms and professional practices.
InvoSeal is a cloud-based web application designed from its architecture to offer dual mode. The user can configure whether to operate in VeriFactu (with automatic submission to the AEAT) or No-VeriFactu (with local custody, electronic signature and event log), and switch modes as needed while respecting the time restrictions set by the regulation.
Specialised ERPs such as ClaveiPro, ClaveiGes and the Inforges integrations for SAP Business One also offer dual mode, generally activated via a configuration toggle. They are the natural choice for industrial SMEs, distributors or agri-food companies that may have operating centres with and without connectivity.
ClassicGes (AIG) is another interesting dual option for retail and distribution, with its Responsible Declaration updated in each Service Pack.
VeriFactu-only software
These programs only allow operation in VeriFactu mode. Every invoice you issue generates a record that is automatically sent to the AEAT. You have no option to retain records locally.
Advantage: maximum simplicity. There is nothing to decide: everything is sent. Ideal if you have no objection to the tax authorities having immediate and complete visibility of your invoicing.
Drawback: no flexibility. If at any point you need to operate in an environment without connectivity or prefer not to give the AEAT real-time access (for example, given the possibility of the tax authorities issuing credit seizure notifications on recently registered invoices if you have outstanding debts), you will not have that option. The software provider has made that decision for you.
The AEAT's free application is the most obvious case: it operates exclusively in VeriFactu, does not allow exporting records to another SIF and has functional limitations (no simplified invoices, no accounting integration). But for a freelancer with few invoices per month, it does the job perfectly.
Others such as Facturavia, SeniorConta / SeniorFactu (by DSG Software) or Verifacti also operate exclusively in VeriFactu. SeniorConta is a desktop program with a cloud option, aimed at SMEs and freelancers, combining invoicing and accounting with automatic submission to the AEAT. Verifacti works as an API for developers who want to integrate AEAT submission into their own software without developing the communication layer.
Software with active VeriFactu submission (dual mode not explicitly confirmed)
Several popular programs have announced their VeriFactu adaptation and offer record submission to the AEAT, but do not explicitly document a configurable No-VeriFactu mode. This does not mean they lack it internally — they may simply not highlight it commercially because the AEAT encourages VeriFactu — but it is worth asking the provider directly before assuming the option exists.
Quipu has completed its adaptation and issues invoices with an AEAT stamp, QR and verifiable URL. Its approach is clearly VeriFactu-oriented, with powerful banking integration (OCR, reconciliation).
TeamSystem Factusol and TeamSystem Facturas Billin (formerly Billin) are adapted with automatic submission, QR and immutable records. Factusol has the advantage of integrating inventory management, collections and payments in a very complete environment for SMEs.
STEL Order targets service companies with mobile workforces (plumbers, electricians, maintenance), with a native app and field invoicing.
Declarando combines VeriFactu invoicing with tax planning and deduction management, making it attractive for freelancers looking to optimise their income tax.
Non-compliant software: what no longer works
From 2027 onwards, it will no longer be valid to invoice with Excel, Word, editable PDF templates or any program that does not meet the RRSIF requirements. The fine for merely using non-compliant software is up to €50,000 per fiscal year, without the AEAT needing to prove fraud.
If you currently invoice with any of these tools, 2026 is the year to migrate. The AEAT's recommendation for those using non-compliant software is to export historical records and uninstall the program before the compliance deadline.
What to ask before you buy
Before choosing invoicing software, ask the provider these questions:
Does it have a published Responsible Declaration? This is the only document that certifies compliance. If it does not have one, it is not legally compliant. Remember: the AEAT does not certify software; it is the manufacturer who self-certifies.
Does it support dual mode (VeriFactu and No-VeriFactu)? If you value being able to choose, make sure the option exists and is documented. If it only offers VeriFactu, understand what that implies in terms of visibility to the tax authorities.
What happens if I want to change mode? The regulation allows switching from No-VeriFactu to VeriFactu at any time. But once VeriFactu is activated, the option remains in effect at least until 31 December of the following year. The reverse switch has restrictions.
How does it handle submission incidents? In VeriFactu mode, if the connection to the AEAT fails, the system must retry periodically. Ask whether it has an automatic send queue and error handling.
Does it integrate with my accounting, bank or ERP? Invoicing does not exist in a vacuum. Consider whether the program connects with your actual workflow.
What does it cost and what is included? Some basic plans do not include VeriFactu or offer it as an add-on. Verify that compliance functionality is included in the plan you are purchasing.
Conclusion
There is no universally "best software". The choice depends on your invoicing volume, your technical infrastructure, your comfort level with tax authority visibility, and the degree of integration you need with other systems.
What is universal: from 2027, the software you use must comply with RD 1007/2023. If it does not, the financial consequences can be severe. And if you are still invoicing with Excel or templates, the clock is ticking.
