Spain's mandatory e-invoicing between businesses comes from the Crea y Crece Law, developed by Royal Decree 238/2026 (in force since 20 April 2026). Its deadlines are set by Order HAC/1028/2026 of 2 October (BOE of 5 October 2026, in force since 6 October): October 2027 for businesses that invoiced more than €8 million in the previous year and October 2028 for everyone else. Anyone selling you an urgent adaptation «because it's already in force» is telling half the story.
Mixing up Verifactu and B2B e-invoicing is the most common question we get. The quick way to keep them apart:
Law 11/2021 and RD 1007/2023: your software must sign and chain every invoice, with a QR code and an unalterable record. 1 January 2027 (companies) and 1 July 2027 (self-employed and others); postponement to October 2028 announced, pending publication in the BOE. Fines up to €50,000 per year.
Crea y Crece Law, RD 238/2026 and Order HAC/1028/2026: an invoice in EN 16931 format (UBL), sent through the AEAT's free public solution or through interconnected private platforms; the recipient reports any rejection and the payment.
One does not replace the other. A business invoicing other businesses will end up complying with both — and the sensible thing is for its ERP or module to solve both without parallel systems.
Order HAC/1028/2026 (BOE of 5 October 2026) now sets the deadlines. This is what is published.
The calendar trap: even if you are in scope in 2028, your large customers are in scope a year earlier — and they will ask their entire supplier base to adapt. Full detail, with sources, in our B2B e-invoicing guide (Spanish).
It is the obligation that comes first (published deadlines in 2027; postponement to October 2028 announced, pending publication in the BOE). Unsure whether it applies to you and from when? The calculator tells you in a minute.
What their e-invoicing plan and date are. GoldenSoft, the ERP we implement, is ready for Spain's mandatory e-invoicing.
VeriVenta, our Verifactu module for PrestaShop and WooCommerce, will evolve on the same platform: today's investment keeps its value tomorrow.
It will remain the visual copy for people. What changes is the file that travels between machines, not what you read.
We write only when VeriVenta and our ERPs support B2B e-invoicing. No weekly emails. Email confirmation (double opt-in), one-click unsubscribe.
General information, not tax advice: the e-invoicing dates are those of Order HAC/1028/2026, published in the BOE of 5 October 2026. The Ministry of Finance has not yet clarified what happens with voluntary users or what obligations software manufacturers will have.
Not yet, but it now has dates. The regulation (RD 238/2026) has been in force since 20 April 2026, and Order HAC/1028/2026, published in the BOE of 5 October 2026 (in force since 6 October), sets the deadlines: October 2027 for businesses that invoiced more than €8 million in the previous year and October 2028 for everyone else.
October 2027 if your business invoiced more than €8 million in the previous year, and October 2028 for everyone else (self-employed included), under Order HAC/1028/2026, published in the BOE of 5 October 2026.
No. They are two different obligations: Verifactu concerns how you issue (signed record, QR). Published deadlines: 1 January 2027 (companies) and 1 July 2027 (self-employed and others), under Royal Decree-law 15/2025. Postponement announced by the Ministry of Finance on 5 October 2026: October 2028 for everyone, pending publication in the BOE. B2B e-invoicing concerns the format and the channel the invoice travels through. You will end up complying with both, ideally with the same system.
Solve Verifactu (published deadlines and an announced postponement, pending publication in the BOE); ask your ERP or provider in writing what their e-invoicing plan is; and if you sell through an online store, join our alert: VeriVenta will evolve on the same platform, with no system change.

It's the cascade effect: those in scope in 2027 will ask their whole supplier base to adapt earlier. Tell us your case and we'll tell you what we would do — and what isn't needed yet.
