FactuSign is the Verifactu module for PrestaShop 8.0–9.x: it signs every order invoice, chains it with SHA-256 hashes and submits it to Spain's tax agency (AEAT) in real time, with the VERI*FACTU QR visible on the PDF invoice and in your customer's email. Tested end-to-end against the AEAT's official sandbox, with real REGISTERED records and CSVs. Built for stores selling in Spain — support in English and Spanish.
FactuSign lives where you already work: the PrestaShop order list. No external panels for the day-to-day.
Connect in 3 guided steps. No config files, no console.
In the order list you see at a glance which invoices are submitted and which are pending.
Every order with its AEAT CSV and a retry button, in case you want to force it yourself.
Issue a credit or a refund and the corrective invoice goes out on its own, also compliant.
If the tax agency or the network fails, the queue retries on its own until submitted. You do nothing.
FactuSign works after the sale: it does not touch your theme, your checkout or your store's speed.
If you have ever installed a module, you already know how. If not, the manual has screenshots.
In your back office: Modules → Module Manager → Upload a module, and drop the FactuSign zip.
The 3-step wizard registers your signing service and checks the connection with the AEAT.
From that moment, every new invoice goes out signed, chained and submitted. Past invoices are not touched.
No theme changes, no checkout changes, no config files. If anything gets stuck, email support in English and Spanish — and if we maintain your site, we install it for you.
The only dates that matter: 1 January 2027 for companies and 1 July 2027 for the self-employed. The SII and the chartered territories are out of scope (TicketBAI — included in FactuSign depending on your territory). Unsure about your case? Answer it in one minute with the calculator or read the full guide. And don't leave it for December 2026: the whole market will be installing at once.

PrestaShop 8.0 to 9.x. If your store runs 1.6/1.7, the honest answer is that the path goes through upgrading the store — we can quote that — or invoicing from a compliant ERP connected to the store.
No. FactuSign acts after the sale, on the order invoice: it does not modify the theme or the purchase flow, and it does not affect store speed.
No. Truly unlimited: no volume tiers. Whether you issue 50 or 50,000 invoices a month, the price is the same.
Corrective invoices go out on their own: you issue the credit or refund in PrestaShop and FactuSign generates and submits the compliant corrective invoice, no extra steps.
Included at no extra cost depending on your regional territory.
Probably not: if your ERP does the invoicing, the ERP is what must comply, and the right move is connecting the store to the ERP. FactuSign is for stores that invoice from the store itself. Unsure? One minute with the calculator.
