Verifactu and mandatory e-invoicing in Spain: what applies to your company now.

Two separate obligations, two different laws, two different deadlines — and almost every foreign-owned Spanish company confuses them. One of them is already in force for small and medium companies. This is the working explanation of which is which.

Verifactu — large companies
1 Jan 2026
In force for companies with turnover above €6 million.
Verifactu — SMEs and autonomos

Already applicable. If your invoicing software is not compliant, you are exposed now.
B2B e-invoicing
1 Oct 2027
Deferred. A separate obligation under the Crea y Crece law, not the same thing as Verifactu.

Spain is in the middle of the most significant change to business invoicing in a generation, and it is arriving in two waves that are routinely mistaken for one. A foreign founder who reads that "electronic invoicing has been delayed to 2027" and concludes that nothing is required yet has drawn precisely the wrong conclusion: the obligation that has actually taken effect is the other one.

The distinction matters because the two regimes have different legal sources, different affected parties, different technical requirements and different penalties. A typical Spanish company will end up complying with both, in parallel, on separate timetables.

The two obligations, side by side.

Already in force

Verifactu — how your software must behave

Your billing system must produce records that are traceable, unalterable and verifiable by the tax authority. It governs the software, and it applies to invoices you issue to anyone, including consumers. Source: anti-fraud legislation and its implementing regulation.

From October 2027

B2B e-invoicing — how invoices are exchanged

Invoices between businesses and professionals must be issued and received in a structured electronic format, with status reporting. It governs the exchange, and it applies only to B2B. Source: Ley 18/2022, "Crea y Crece".

The sentence that causes the mistake

"Electronic invoicing has been postponed to 2027."

True of the Crea y Crece B2B regime. Not true of Verifactu, which has applied to small and medium companies since 1 July 2026. If your Spanish SL is invoicing today with a spreadsheet, a generic template or non-Spanish software that was never adapted, that is the exposure to address first.

What Verifactu actually requires of your system.

Verifactu is not a filing you submit. It is a set of properties your invoicing software must have, enforced by making non-compliant software itself unlawful to use and to sell.

01
Unalterable recordsEach invoice generates a record that cannot be modified or deleted after the fact. Corrections happen through documented rectifying entries, not by editing history.
02
Traceability by chainingRecords are linked to one another with a hash, so that removing or altering one breaks the chain visibly. This is the mechanism that ends silent deletion of sales.
03
VerifiabilityInvoices carry a QR code allowing verification, and the software either submits records to the AEAT automatically or keeps them in a compliant, non-modifiable state.

There are two operating modes. In Verifactu mode, records are transmitted to the tax authority automatically as invoices are issued, which relieves the company of certain retention duties. In non-Verifactu mode, records stay with the company but must meet stricter integrity, signature and retention requirements and be available on request. Most standard commercial software defaults to the first.

What to check with your provider — this week
  • Is the software declared compliant? Providers must issue a responsible declaration confirming the system meets the requirements
  • Which mode does it use — automatic submission or compliant local retention
  • Does it cover every invoice stream — including e-commerce, POS, subscriptions and any secondary system
  • Do invoices carry the QR code and required identification
  • How are corrections handled — rectifying invoices, not edits
  • Is your foreign group ERP in scope for the Spanish entity's invoicing, and has it been adapted
  • Who retains the records and for how long

The trap specific to foreign-owned companies.

A Spanish subsidiary of a foreign group usually invoices from the group's existing ERP or billing platform, configured for the parent's home market. That system may be excellent and entirely lawful where it was built — and still fail Spanish requirements, because the requirements are about record integrity in a specific technical form that non-Spanish vendors have had no reason to implement.

Common setup

Group ERP, unmodified

Invoices issued from headquarters' system for the Spanish entity, no Spanish adaptation module, no QR code, editable records, and nobody in the group aware the Spanish rules reach the software rather than the filings.

Compliant setup

Adapted module or local system

Either a Spain-certified module within the group ERP, or a compliant Spanish invoicing system for the local entity, with a provider declaration on file and every invoice stream covered.

The same logic will repeat in 2027 with B2B e-invoicing, which adds a structured-format and status-reporting requirement that group systems will again need to be adapted for. Companies that resolve the invoicing stack properly now generally find the second wave is a configuration change rather than a project.

Where this becomes our work

Invoicing system, filings and deadlines as one file.

We check whether your Spanish entity's invoicing meets current requirements, fix what does not, and carry the ongoing filing calendar — so the 2027 wave is a configuration change, not an emergency.

The sequence to follow.

Step 01
Inventory every invoice streamMain ERP, e-commerce platform, point of sale, subscription billing, manual invoices from spreadsheets. Each one is separately in scope, and the forgotten stream is usually the manual one.
Step 02
Obtain the provider declarationAsk each software vendor for written confirmation of compliance. If a vendor cannot produce one, that is your answer about the system.
Step 03
Decide the modeAutomatic submission to the AEAT or compliant local retention. The first is simpler operationally for most companies; the second requires more of your own controls.
Step 04
Retrain on correctionsStaff who are used to editing an invoice must switch to issuing rectifying invoices. This is the process change that causes the most friction and the most accidental non-compliance.
Step 05
Plan for 2027Confirm with your provider how the structured B2B format and status reporting will be delivered, and whether it is included or a separate module.

Frequently asked
Is Verifactu the same as mandatory electronic invoicing?
No, and this is the central confusion. Verifactu regulates how your invoicing software creates and keeps records, applies to B2C as well as B2B, and is already in force for small and medium companies since 1 July 2026. Mandatory structured B2B e-invoicing comes from the Crea y Crece law, applies only between businesses and professionals, and has been deferred to 1 October 2027. Most companies will comply with both.
Can we keep invoicing from our group's ERP abroad?
Only if that system has been adapted to Spanish requirements for the Spanish entity's invoicing. Many international platforms now offer a Spain module; others do not. The practical test is whether the vendor will issue a written declaration of compliance. If they will not, the Spanish entity generally needs a compliant local solution.
What if we only invoice a handful of clients?
Volume does not exempt you. The requirements attach to the act of issuing invoices, not to scale, and low-volume companies invoicing from spreadsheets or generic templates are among the most exposed precisely because they never considered themselves a software case.
Do these rules apply if our company is dormant?
If you are not issuing invoices, the software requirements have nothing to attach to — but a dormant Spanish company still has annual filing and accounting obligations that continue regardless of activity, and those are a separate and frequently neglected exposure.
What happens if we are not compliant right now?
The exposure is real, with reported penalties of up to €50,000 per year for using non-compliant invoicing software, alongside separate sanctions for producing or marketing it. The practical response is to establish the position with your provider immediately and to move to a compliant system rather than waiting to be asked.
Position as at August 2026, reflecting the Spanish anti-fraud invoicing framework and Ley 18/2022 (Crea y Crece), including the deferral of mandatory B2B electronic invoicing. Dates, thresholds and penalty figures are summarised from public sources and should be verified against the current official text. General information, not legal or tax advice — the application to your systems and invoice streams is fact-specific and requires professional review.
