E-Signature in Spain: Signaturit, Firmafy, Docuten and Viafirma Compared

A buyer comparing e-signature platforms in Spain is choosing from a shortlist that barely overlaps with the English-language reviews: Signaturit, Firmafy, Docuten and Viafirma. The first thing to know about that shortlist is that half of it will not tell you what it costs until you talk to a salesperson.

Every figure below was read on each vendor’s own page on the check date shown above. Prices in this category move, so confirm the current plan before you buy.

Half of this market does not publish a price

Signaturit and Firmafy print their self-serve plans where anyone can read them. Docuten and Viafirma publish nothing, and both say so themselves.

Docuten’s own FAQ answers the question directly: “El coste de Docuten varía en función del volumen de documentación que, como empresa, envíes a firmar, o en función de las facturas que emitas y recibas. Nuestra propuesta económica se adaptará al 100% a ti”, and closes by promising “un presupuesto personalizado para tu empresa”. There is no pricing page anywhere in its published sitemap and no Precios entry in its navigation.

Viafirma is the same shape, with one useful difference in what it does publish. Its FAQ states that “Todas las funcionalidades de nuestro software están disponibles independientemente del plan que se contrate” — every feature on every plan — while noting that “algunas funcionalidades, como el envío de SMS o las verificaciones de identidad mediante onboarding, tienen un costo adicional”. The plan itself is quoted: “Habla con nuestro equipo y te daremos un plan a medida.”

That is not a criticism. Both sell heavily to enterprises and public administrations, where a list price would be fiction anyway. It is a scheduling fact: two of your four candidates cost a sales call before you can compare them, and you should start those conversations first rather than last.

The four platforms, from their own pages

• Signaturit. Its pricing page sells per user with a monthly/annual toggle marked “Ahorra hasta un 20 %”. Business is 43€ per user per month billed monthly and 35€ billed annually — the page prints both as “516 €” and “420 € por usuario y año” — with “Firma simple” carrying “5 créditos regalados”, “Firma avanzada con biometría” capped at “Hasta 5 envíos al mes” (“Hasta 60 envíos al año” on the annual view) and “Hasta 3 plantillas de documentos”. Business+ is 72€ / 57€ (“864 €” / “684 € por usuario y año”), raising advanced signatures to “Hasta 20 envíos al mes”, adding “Firma cualificada” “con certificados QSCD alojados en IvSign”, “Hasta 5 plantillas” and certified delivery at “Hasta 20 emails certificados al mes”. Enterprise is quoted. Two things the page states about the company matter as much as the numbers: it is “Signaturit Group, a Namirial Company”, and its own FAQ says “somos una empresa reconocida como Prestador cualificado de servicios electrónicos de confianza por el Ministerio de Asuntos Económicos y Transformación Digital de España”. Note also that the plans carry “(Servicio no disponible para Consumidores)”.
• Firmafy. Its tarifas page sells the plan rather than the seat, and meters sends. On annual billing, BUSINESS is 30€/mes with “(Pago único: 360€)” for “200 envíos/año” and “Incluye 2 usuarios”; ENTERPRISE is 60€/mes (“Pago único: 720€”) for “500 envíos/año” and “Incluye 5 usuarios”. Switch the page to Pago mensual and the same two become 50€ for “15 envíos/mes” and 100€ for “40 envíos/mes” — the annual saving it advertises as “¡Ahorras 40%!”. Its published comparison table carries the details that decide the bill: “Usuarios extra” at 90€ extra on annual plans and marked ”✗” on monthly ones, API access and bulk sending both ”✗” on Business, “Multicif” at “120€ extra” on Enterprise only, unlimited storage and templates, “Custodia de documentos” of “10 años”, and a “Vigencia del plan” of “1 año”. It describes itself as “prestadores de servicios electrónicos de confianza según el Reglamento UE 910/2014” — trust service provider, without the word cualificados. The trial is “7 días gratis” with “No se necesita tarjeta de crédito.”
• Docuten. No published price, as above. What its FAQ does publish is scope and status. On status: “También estamos reconocidos por la misma regulación como un proveedor de servicios de confianza calificado (QTSP)”, and “A través de esta página oficial puedes encontrarnos como Prestador de Servicios Electrónicos de Confianza Cualificados.” On retention: “Como Prestador de Servicios de Confianza, estamos obligados a custodiar toda esa información durante un periodo mínimo de cinco años.” On scope, it is the outlier here — signature sits alongside electronic invoicing under the Ley Crea y Crece and transport documentation (DeCA, eCMR), so it is competing for a wider budget than a signature tool.
• Viafirma. No published price, as above. Its published positioning is the inverse of the usual tiering: every feature on every plan, with SMS and identity-onboarding verification billed separately. Its own materials place it as a long-standing Spanish provider with operations across Spain and Latin America.

The axis that actually decides it: which eIDAS level you need

In the US category the argument is about price per seat. In Spain it is usually about level, and that is a legal question before it is a commercial one. eIDAS defines three: simple (SES), advanced (AdES) and qualified (QES), and only QES carries automatic handwritten-equivalent effect across the EU under Article 25(2). We set out the three tiers, and which one a normal commercial contract actually needs, in eIDAS explained: SES, AdES and QES.

This is where the Spanish vendors genuinely differ from the international ones, and from us. A qualified signature requires a qualified certificate from an accredited Qualified Trust Service Provider. Signaturit and Docuten both state on their own pages that they hold that status; Firmafy describes itself as a trust service provider without the qualified wording. Because that status is a matter of public record rather than marketing, do not take anyone’s word for it — including ours. The authoritative register is the European Commission’s EU Trusted List browser, which lists every accredited provider and the exact services each one is accredited for. Check the specific service you need, not just the company name.

For the overwhelming majority of commercial agreements you do not need QES at all. But if your transaction is one that Spanish law reserves for it, that requirement decides your vendor before price does.

Signatura is not Signaturit

These are two different companies, with no relationship between them, and the names are one letter apart. Since you may have arrived here from a search that conflated them:

• Signaturit is a Spanish provider, founded in Barcelona, now part of Namirial — its own site carries the line “Signaturit Group, a Namirial Company”. It sells qualified trust services, certificate issuance and certified delivery alongside e-signature, priced per user with the send meters described above.
• Signatura is us: getsignatura.com. We sell one thing — sending documents for signature — on one plan, per seat, with unlimited documents and no send meter. We are not a trust service provider and we do not issue certificates, so we cannot produce a qualified signature.

If what you need is a QES or a digital certificate, Signaturit is the one of the two names that can issue it. If what you need is unmetered sending at a predictable price, that is what we built. Neither of us is the other.

What to check before you sign anything

1. Which eIDAS level your documents actually require. Get this answer first. It can eliminate half the shortlist, in either direction.
2. What the meter counts. Signaturit meters advanced biometric signatures, not sending in general; Firmafy meters total sends. Those are different constraints, and your own document mix decides which one bites.
3. How many people need to send. Firmafy includes 2 users on Business and charges 90€ for each additional one on annual plans — and its own table marks extra users ”✗” on monthly billing. Signaturit prices per user from the start.
4. What is billed per use rather than included. Viafirma names SMS and identity onboarding explicitly. Assume the same question applies everywhere and ask it.
5. How long your documents are kept, and by whom. Firmafy publishes “10 años”; Docuten cites a five-year minimum that follows from its trust-service obligations. If a contract may be litigated years later, this is not a footnote.
6. Start the two quote-only conversations early. Docuten and Viafirma cannot be compared on a spreadsheet you build alone.

Where Signatura fits

Signatura is deliberately narrower than everything above: one plan, priced per seat, with unlimited documents and no send meter — no annual envelope allowance, no per-send charge, and no fee for the people who sign. If your volume is high and your team is small, that is cheaper to run and far easier to forecast than any metered plan on this page.

Our pricing page prices in euros for a visitor in Spain — from 21€ per seat per month on the annual plan, 28€ billed monthly, with volume discounts, as shown on our pricing page. The comparison worth making is still the structural one: a send meter you have to forecast against a seat you do not. Every completed document carries a full audit trail and a SHA-256 tamper-evident seal that can be re-verified at any time — see our security page.

Where Signatura is not the right answer, stated plainly: we produce Simple Electronic Signatures, which are admissible and sufficient for the vast majority of commercial agreements but are not a QES. If your transaction needs a qualified signature or a digital certificate, you need an accredited provider, and several of the vendors above are exactly that. We would rather say so than oversell. The same shape, in a market that prices by the document instead of the seat, is in e-signature in Brazil. Portugal runs the same argument from the other end, because there the state issues the qualified signature itself: e-signature in Portugal. In Mexico every platform on the shortlist publishes a price, but each meters the document a different way: e-signature in Mexico.

Frequently asked questions

Is Signatura the same company as Signaturit?

No. They are unrelated companies whose names differ by one letter. Signaturit is a Spanish provider now part of Namirial — its own site carries the line “Signaturit Group, a Namirial Company” — and it states that it is a qualified trust service provider recognised by Spain’s Ministry of Economic Affairs and Digital Transformation, selling certificate issuance and qualified signature alongside e-signature. Signatura is a separate product at getsignatura.com: one plan, per seat, unlimited documents, no send meter, and no certificate issuance. We are not a trust service provider and cannot produce a qualified signature.

What does e-signature cost in Spain?

It depends on which two of the four you can even price. On their own published pages, Firmafy’s Business plan is 30€ a month on annual billing — a single payment of 360€ — for 200 sends a year and 2 users, with Enterprise at 60€ (720€) for 500 sends and 5 users. Signaturit’s Business plan is 43€ per user per month billed monthly or 35€ billed annually, with advanced biometric signatures capped at 5 sends a month, and Business+ at 72€ / 57€ raising that cap to 20 and adding qualified signature. Docuten and Viafirma publish no prices and quote per customer.

Do I need a qualified electronic signature in Spain?

Usually not. Under eIDAS, a simple or advanced signature cannot be denied legal effect or admissibility merely for being electronic, and that covers the overwhelming majority of commercial contracts. A qualified signature is required only where national law reserves it — certain real-estate transfers, notarial acts and some corporate filings. Settle that question first, because it is the one thing that can rule a vendor in or out regardless of price. The three tiers are set out in eIDAS explained: SES, AdES and QES.

How do I verify that a provider is really a qualified trust service provider?

Do not rely on the vendor’s own page, or on ours. Qualified status is a matter of public record: the European Commission publishes the EU Trusted List browser, which lists every accredited provider per member state along with the specific services each is accredited for. A company can be qualified for one service and not another, so check the service you need rather than the name alone.
