A plain-language guide for companies, sole traders, online stores and accounting firms selling into or operating in Spain. Updated 18 August 2026 with the calendar in force after the December 2025 postponement.
Short answer: if you issue your invoices with a program (an online store does) from Spain's common territory and you are not under the SII, yes.
From when: companies (corporate income tax payers) from 1 January 2027; sole traders and other taxpayers from 1 July 2027.
What it requires: that the program records every invoice in a chained, unalterable way, with its QR code, and — if you choose the VERI*FACTU mode — sends it to the AEAT automatically. If you don't comply: €50,000 per tax year.
What everyone calls “Verifactu” is Spain's Regulation on invoicing computer systems (Royal Decree 1007/2023, implementing Act 11/2021 against tax fraud). It requires the software you issue invoices with to guarantee integrity, preservation, traceability and inalterability of the records: every invoice is chained to the previous one with a hash, carries a QR code and cannot be altered without leaving a trace.
Within that regulation there are two modes: VERI*FACTU, where the program submits the records to the tax agency automatically and almost in real time, and “non VERI*FACTU”, where the records are kept electronically signed without being sent. Both comply; the first spares you custody and proof, which is why it is becoming the norm.
What Verifactu is not: mandatory B2B e-invoicing (Crea y Crece Act). They are two different obligations: Verifactu is about how you issue; B2B e-invoicing is about the format in which you issue and receive between companies, expected in phases from October 2027, timetable pending final confirmation. Verifactu does not touch reception either: the software you process your suppliers' invoices with is out of scope.
The general rule is simple: if you invoice with software in the common territory and you are not under the SII, it applies. The nuances are in the table.
| Your situation | Applies? | From when | What to do |
|---|---|---|---|
| Company (S.L., S.A., cooperative…) invoicing with a program | Yes | 1 January 2027 | Compliant program (or your ERP updated) before that date |
| Sole trader or professional invoicing with a program | Yes | 1 July 2027 | Compliant program; for basic volumes the AEAT's free app may be enough |
| Online store (PrestaShop, WooCommerce…) issuing the invoice from the store itself | Yes | Depending on company / sole trader | Compliant module in the store (e.g. FactuSign) |
| You invoice from your ERP (GoldenSoft, GLOP…) and the store only records orders | Yes (the ERP) | Depending on company / sole trader | Compliant ERP and store connected to the ERP |
| Company under the SII (Immediate Supply of Information) | No | — | Excluded by art. 3.1.a of the regulation: you already report through the SII |
| Tax residence in the Basque Country or Navarre | Depends | Regional system | TicketBAI / regional system instead of Verifactu; case by case if you operate in several territories |
| Invoices in Word or Excel only to write, print and keep them | Not an invoicing system | — | Per the AEAT FAQ it is not an invoicing computer system; if the sheet has macros or generates the invoice register, it is |
| Legacy or custom invoicing application you do not want to replace | Yes | Depending on company / sole trader | Adapt it or integrate fiskaly via API without replacing it |
| You manufacture or sell invoicing software | Yes (a different obligation) | Already in force | Responsible declaration of compliance; the manufacturer's penalty is €150,000 |
The original calendar pointed to 2025 and then 2026. In December 2025 it was postponed and stands as it is today: 1 January 2027 for corporate income tax payers and 1 July 2027 for sole traders and other taxpayers. Those are the only dates that count; anything else you read is a draft or an earlier version.
A practical tip: do not leave it for December. Adapting a store or an ERP takes weeks, and in the last quarter of 2026 the whole sector will be doing the same.
PrestaShop or WooCommerce store invoicing from the store → a compliant module. FactuSign signs, chains and submits every sale in real time; unlimited invoices, €19.90/month or €14.90/month forever if you sign up before 31 December 2026.
You invoice from an ERP → the ERP must be compliant (GoldenSoft and GLOP are) and, if you also sell online, we connect the store to the ERP so the ERP does the invoicing. If you have no ERP and want one, the initial consultation is free.
Legacy or custom program → no need to throw it away: fiskaly (the signing provider FactuSign uses) is integrated via API and your application starts issuing compliant invoices.
Accounting or advisory firm → your client portfolio splits into those three cases; all three have a way out without the client changing advisor. Write to us about the referral agreement.

No. Verifactu (the Regulation on invoicing computer systems, Royal Decree 1007/2023) governs the software you ISSUE invoices with: chained records, a QR code and, if you choose the VERI*FACTU mode, automatic submission to the Spanish tax agency (AEAT). Mandatory B2B e-invoicing (Crea y Crece Act) is a separate obligation, expected in phases from October 2027, with the timetable still pending final confirmation.
Yes, if you issue invoices with a program. The date for sole traders and other taxpayers is 1 July 2027. For very basic volumes the AEAT offers a free invoicing application with limited features; for an online store or a business with some volume, a compliant program is the usual route.
According to the AEAT's FAQ, a word processor or spreadsheet used only to enter data, issue or print the invoice and keep a copy is not considered an invoicing computer system. If the spreadsheet uses macros or generates the invoice register, it is one and must comply. In practice, if you invoice regularly a compliant program saves you trouble.
No. Taxpayers under the Immediate Supply of Information (SII) are excluded from the regulation (art. 3.1.a of RD 1007/2023): they already report to the AEAT through it.
Verifactu applies in the common territory. The chartered territories have their own systems (TicketBAI in the Basque Country; Navarre's own system). If you have stores in several territories it has to be looked at case by case; FactuSign includes TicketBAI at no extra cost depending on your territory.
For whoever holds or uses a non-adapted invoicing system: a fixed fine of €50,000 per tax year (art. 201 bis.2 of the General Tax Act). For the software manufacturer or seller: €150,000 per year and type of system.
Yes: if the store issues the invoice, its software is an invoicing computer system and must comply. If your ERP issues the invoice and the store only records the order, the ERP is the one that must be compliant and the store connects to it.
