The 12 checks (here, in the open)

A · Does it apply to you, and from when?
  1. Do you issue invoices with software (POS, ERP, your store's module…)?
  2. Write down YOUR date: 1 Jan 2027 (companies) · 1 Jul 2027 (self-employed).
  3. Are you under SII or in a foral territory (Basque Country / Navarre)?
B · Your invoicing software (get it IN WRITING)
  1. Ask your vendor for their responsible declaration of compliance.
  2. Ask which mode: VERI*FACTU (real-time submission) or “non-verifiable”?
  3. Check every invoice will carry its QR code and the legend.
  4. Ask what happens on corrections: credit note or “delete and redo”?
C · Your online store (the usual blind spot)
  1. Does your PrestaShop / WooCommerce generate invoices? That module is a SIF too.
  2. Invoicing from TWO places (store and ERP)? Choose your model.
  3. Selling on Amazon or other marketplaces? You are still the issuer.
D · Plan and risks
  1. Put a date on it this quarter: don't leave it for autumn 2026.
  2. Know the fine: up to €50,000 per tax year (art. 201 bis LGT).

Frequently asked questions

Is the PDF really free?

Yes: you download it by confirming your email (double opt-in) and you only join this download's list — one-click unsubscribe. We share it because it is the same list we use with clients.

What does the PDF add over this page?

Each box carries its practical note (what to ask for exactly, and why), the official sources with their BOE reference, and a printable A4 format in Spanish and English.

What if I end up with red boxes?

Start with the calculator (your case and date in one minute) and, if your store runs PrestaShop or WooCommerce, FactuSign gets it compliant in VERI*FACTU mode.

Does this also cover B2B e-invoicing?

No: they are different obligations. This checklist covers Verifactu (firm 2027 dates); B2B e-invoicing has a still-indicative calendar — see its guide and waiting list on the e-invoicing page.

Red boxes in part C?

If your store runs PrestaShop or WooCommerce, FactuSign gets it compliant in VERI*FACTU mode — installed, tested and supported from Alicante, Spain.
