Verifactu invoicing for your PrestaShop

Finseed has an official module for PrestaShop. You install it in your store, open its settings and click «Connect with Finseed»: Finseed opens so you can approve the connection, and your store is paired automatically, with no API keys to copy or paste. From then on, every time PrestaShop generates an order’s invoice, Finseed detects it instantly, issues the Verifactu invoice and reports it to the tax agency for you. You don’t need to touch any code or build an integration: the module handles the notification and Finseed does the entire fiscal side. Communication between your store and Finseed is signed in both directions. How to install and connect the module.

No, and that matters for your legal protection. The module does not issue the invoice: it only tells us PrestaShop has created a new invoice. Finseed generates and signs the Verifactu invoice and files it with the AEAT, outside your PrestaShop. Under Verifactu, the software that generates invoices (the SIF) takes on strict legal obligations, including a declaración responsable filed with the AEAT. With Finseed, we are the SIF, and that responsibility is ours, not yours. A module that generates and signs invoices inside your own PrestaShop makes you the integrator of the billing system, with the obligations that come with it.

No, never, not even when you go live. As colaboradores sociales de la AEAT, we sign and submit your billing records with our own certificate. You only approve an authorization when you sign up, and you're ready to invoice. This is a real practical difference from the modules that run inside PrestaShop with your own certificate: those require you to obtain your digital certificate (FNMT or Camerfirma), install it on your server and renew it every year. With Finseed you don't have to manage any certificate.

In Spain there is no such thing as an «official homologation» for Verifactu software: no vendor can show you an AEAT homologation certificate, no matter what their website says. What the law requires is a declaración responsable (statement of compliance) from the software maker (RD 1007/2023), and ours is public: you can download it and send it to your accountant. We are also colaboradores sociales de la AEAT, the official status that lets us submit invoices to the tax agency on our clients’ behalf. If your accountant asks for «the certificate», send them these two references: it’s exactly what they need to see.

The deadline was postponed from 2026 to 2027: companies must issue their invoices with Verifactu from January 1st, 2027, and self-employed workers and other professionals from July 1st, 2027. Invoicing systems have been adapted since July 2025, so you can implement Verifactu before it becomes mandatory and make the switch calmly. We explain it in detail in this article.

Every refund you process in PrestaShop automatically generates its credit note and reports it to the AEAT, without you doing anything. This includes partial refunds: if a customer returns 1 of 3 items from an order, Finseed reads exactly which lines and amounts were refunded and issues a corrective invoice that adjusts each VAT rate independently. Partial refunds are the case that causes the most trouble in e-commerce invoicing, which is why we treat it as a first-class case, not a premium feature. More on credit notes.

Finseed classifies every sale automatically: standard Spanish VAT in its different rates, IGIC for the Canary Islands and IPSI for Ceuta and Melilla, intra-EU B2B sales exempt with VAT number validation against VIES, the OSS scheme for B2C sales within the EU, and exports outside the EU. We validate your customers’ NIF against the AEAT census before issuing, and if an operation arrives misclassified we block it before sending it to the tax agency, instead of issuing an incorrect invoice. A sale of goods from mainland Spain to the Canary Islands charged with VAT, instead of exempt as an export, is a wrongly issued invoice: this is exactly the kind of mistake Finseed exists to prevent. See the supported tax types.

Yes. Finseed automatically decides between a simplified and a full invoice based on the customer’s data, and keeps a separate numbering series for each type, as the regulation requires. The module adds a smart NIF/CIF field to the checkout: below the threshold you choose (€400 or €3,000) it is optional, and only buyers who need a full invoice fill it in; above it, on purchases in euros, the NIF becomes required and payment methods are not shown until it’s provided. That way you don’t add friction to private purchases or lose conversion. The number is validated in real time against the tax agency. How to set up NIF capture.

Yes. You can correct an invoice (for a refund, an amount error or a data change), fix the customer’s name or NIF after it was issued, and void invoices, all from Finseed, always leaving the trail Verifactu requires: under Verifactu, an invoice already sent to the AEAT is never deleted, it’s corrected with the matching document, and Finseed picks the right mechanism for each case (credit note, correction or void). The original is marked as replaced and your numbering always stays correlative. How to void an invoice.

In the header of every invoice we issue, at the legally required size, with the AEAT verification link. Your customers can scan it to confirm the invoice was reported to the tax agency. You don't have to configure anything: it's included on every invoice type, including simplified invoices and credit notes.

Finseed generates the Verifactu invoice, with its QR code and the AEAT legend, on our servers. Once your store is live, the module automatically replaces PrestaShop’s native PDF with ours in the download from «My account» and in the back office downloads. PrestaShop’s order emails stop attaching its invoice PDF, so your customer does not receive two different documents. It comes switched on, so you don’t have to disable anything by hand. To have the invoice emailed to your customer, turn on automatic sending: we email it on your behalf, with your store’s name as the sender. How we deliver the invoice to your customer.

The module works with PrestaShop 1.7.8 through version 9 and PHP 7.4 or later. It’s compatible with PrestaShop multistore: you can connect all your stores to the same Finseed account, each with its own invoicing series, pairing each store separately from the module. If you run a non-standard setup, write to us and we’ll review it with you. Requirements and installation steps.

Yes, with all of them. Finseed connects to your PrestaShop orders, not your payments, so it doesn't matter whether you charge with Redsys, Stripe, PayPal, Bizum, bank transfer or cash on delivery: once PrestaShop generates the order's invoice, the Verifactu invoice is issued the same way.

You can issue standalone invoices from Finseed without needing a PrestaShop order, with the same controlled numbering and the same submission to the AEAT: useful for in-store sales, quotes closed over the phone, or any sale outside your website. And if you run several online stores, you can connect them all to the same account, each with its own series. How to issue standalone invoices.

Yes. You set up your series starting from the number you’re already at (for example, if your last invoice was F-2026-0341, the next one will be F-2026-0342), and numbering continues without gaps or duplicates. The Verifactu fingerprint chain starts fresh in Finseed, as the regulation requires for a new invoicing software, even though your invoice numbering continues where you left off. You don’t need to wait until January 1st to switch systems. Configure your numbering series.

Yes, all of them, whenever you want. Your invoices and your data are yours: you can export them as PDF and Excel at any time, even if you downgrade to the free plan. You keep access to your history for inspections and for your accountant. Choosing a billing system shouldn’t be an irreversible decision, and we don’t want customers who are trapped: we want customers who stay because the product works. How to export your invoices.

Yes. If you build or maintain PrestaShop stores for clients, you can manage several companies from Finseed, and we run a partner program for agencies and freelancers. Setup is the same as for your own store (module plus connection with Finseed), and the free test mode lets you validate the integration on each project before going live. Check the partner terms.

From €14.95 a month, with a genuine monthly subscription: you pay month to month and cancel whenever you want, with no commitment and no annual payment upfront. Every Verifactu invoicing feature is included on every plan, with no invoice limit, and you can connect several stores on any of them. Before you sign up anywhere, check the fine print: in this market it’s common to advertise a «per month» price that’s actually billed as a prepaid annual licence, or to cap the number of invoices per plan. See plans and pricing.

Yes, with the free, unlimited test mode: you connect your real store, issue test invoices and see exactly how everything will work, with nothing sent to the AEAT and no card required. When you’re ready, you switch to live mode and start invoicing for real. How to go from test to live mode.
