FactuSign is the Verifactu plugin for WordPress 6.x + WooCommerce: it signs each order's 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 invoice and in your customer's email. The same signing engine as our PrestaShop version, tested end-to-end against the AEAT's official sandbox. Built for stores selling in Spain — support in English and Spanish.
FactuSign lives where you already work: your WooCommerce orders. 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.
Two minutes, from the WordPress dashboard itself. With screenshots in the manual.
In your WordPress: Plugins → Add New → Upload Plugin, and select 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.

Yes: FactuSign acts after the sale, on the order's invoicing — it does not touch the theme or the checkout, and it does not interfere with your shipping or payment plugins.
The Verifactu requirement falls on the billing record: FactuSign signs, chains and submits every invoice with its QR. Tell us which PDF plugin you use and we will confirm the fit for your case before you buy — the consultation is free.
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 refund in WooCommerce 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.
Invoice plugins already installed, multisite, a pending migration… write to us with your case and we will tell you what we would do, no strings attached. And if you prefer that we install it for you, we do that too.
