E-Signature in Brazil: Clicksign, ZapSign, D4Sign and Autentique Compared

A buyer comparing e-signature platforms in Brazil is not choosing between the names that dominate the English-language reviews. The shortlist is local — Clicksign, ZapSign, D4Sign and Autentique — and so is the pricing model, which works in the opposite direction from the one DocuSign and its competitors use. Getting that difference straight is most of the decision.

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

The Brazilian category meters documents, not seats

In the US and European category the unit is the seat: you pay per person who sends, and the envelope allowance is a secondary constraint bolted onto it. We set that model out in full, from the vendors’ own pages, in the cheapest way to get legally binding e-signatures. Spain inverts it a third way — half its shortlist publishes no price at all, and the argument there is about the eIDAS level rather than the meter: e-signature in Spain. Portugal inverts it a fourth way, with the state itself issuing a qualified signature to nine and a half million people: 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.

All four Brazilian platforms invert it. The first question every one of their pricing pages asks is how many documents you send per month, and the price follows from that number. Clicksign puts it plainly on its page: “Escolha quantos documentos você assina por mês — o preço de cada plano se ajusta automaticamente.” D4Sign and Clicksign both present the choice as a slider; ZapSign sells it as a fixed monthly franquia; Autentique sells a free tier capped at documents and a paid tier with none. Every vendor’s meter, allowance and stated overage sit side by side in e-signature send limits and overage.

That has a practical consequence worth stating before the numbers. Headcount is cheap in this market and volume is expensive — which is the reverse of the trade a team used to per-seat pricing expects to make.

The four platforms, from their own pricing pages

• Clicksign. Its pricing page prices three self-serve plans against a documents-per-month slider that starts at 20 and runs 20 / 50 / 100 / 200 / 350 / 500. At the 20-document position it lists Start at R$ 69/mês with “5 usuários”, Plus at R$ 99/mês with “10 usuários”, and Automação at R$ 135/mês, also 10 users. Above them, “Avançado” is “Sob medida” for “300+ documentos por mês” with “Usuários Ilimitados”. Its own comparison table carries the two numbers that decide the bill: “Preço por Usuário” of R$ 15 on all three self-serve plans, and “Preço por Documento Excedente” of “Até R$ 3,00”, “Até R$ 4,90” and “Até R$ 6,90” on Start, Plus and Automação respectively. Its FAQ confirms both that signers never need an account and that “O uso de documentos além do contratado, ou de funcionalidades não incluídas no plano, será cobrado à parte.”
• ZapSign. Its plans and pricing page publishes a full price table rather than a slider, and it is the most transparent of the four. Individual is “Gratuito”, “para sempre”, for one user and “3 documentos por mês”. Profissional carries “10” users and is sold by franchise: R$ 39,90/mês for 20 documents a month, R$ 89,90 for 80, and R$ 149,90 for unlimited. Equipe carries “30” users at R$ 69,90/mês for 20 documents, R$ 119,90 for 80 and R$ 259,90 for 200. Enterprise starts “A partir de R$ 500” a month with unlimited users. Two lines on the same page matter more than the headline: “A franquia de documentos é mensal, inclusive nos contratos anuais” — an annual contract does not let you pool a quiet month into a busy one — and WhatsApp delivery at “Custo: R$0,50 por envio”, optional on Profissional and included from Equipe upward.
• D4Sign. Its plans and pricing page runs the same slider shape — 20 / 50 / 100 / 150 / Ilimitado documents a month — and at the 20-document position lists Starter at R$ 39,90/mês and Advanced at R$ 59,90/mês, with Enterprise “Sob medida”. Both self-serve plans list “Usuários: Ilimitados”, and the page leads on exactly that: “Única plataforma com usuários ilimitados em todos os planos”. Read the asterisk, because it lands on the plan a growing team would pick: ” Exceto o Plano Starter Ilimitado, que conta com limite de 10 usuários e não possui envio em lote.” On Starter, WhatsApp, D4Sign.AI, API Premium and Suporte Premium are each listed “Indisponível”; Advanced lists the first two as “Grátis” and API Premium as “Sob Consulta”.
• Autentique. Its plans are published on its home page rather than at a pricing URL — /precos returns a 404, and the “Conhecer os Planos” button points into the logged-in app — so scroll to “Quanto custa?” to see them. Grátis is R$ 0/mês for “Documentos: 10/mês”, “Usuários: Ilimitados” and “Signatários: Ilimitados”. Profissional is R$ 99/mês with “Documentos: Ilimitados” and users and signers both unlimited. Corporativo is “A partir de: R$ 2.000” a month, adding whitelabel and an SLA. The page offers “15% off” on annual billing. Of the four, this is the only one that does not meter users anywhere, including on the free plan.

Where they actually differ: the second meter

The document meter is universal here, so it is not a differentiator. The user meter is, and it splits the four cleanly:

• Clicksign meters both. A team of eight on Plus is paying the plan price plus R$ 15 for each user past the tenth if it grows, and up to R$ 4,90 for each document past the plan. Two meters running at once is the most expensive shape on this page if your volume is uneven.
• ZapSign caps users without charging per user — 10 on Profissional, 30 on Equipe — and meters documents by a franchise that, per its own page, does not carry across months.
• D4Sign and Autentique advertise unlimited users. Autentique’s holds everywhere on its published plans. D4Sign’s holds except on “Starter Ilimitado”, which its own footnote caps at 10 users and strips of bulk sending.

Notice what both “unlimited” claims have in common: the exception, where there is one, is attached to the tier a business grows into rather than the one it starts on. That is not a criticism of either vendor — both publish the exception on the same page as the claim. It is a reason to price the plan you would be on in a year, not the one you would sign today.

What to check before you sign anything

1. Your real monthly document count, at your busiest month. Every plan here is bought against that number, and every one of them resets monthly. An average month will understate what you need.
2. What happens the month you go over. Clicksign publishes a per-document overage; the others move you to a larger franchise. Ask for the figure in writing before you need it.
3. Whether the allowance pools. ZapSign states plainly that it does not, even annually. Assume the same elsewhere unless the vendor says otherwise.
4. How many people need to send, as distinct from how many people sign. Signers are free and account-free across this category — Clicksign’s FAQ says so directly. Senders are the licensed unit.
5. Which authentication you actually need, because several are billed per use rather than included. Clicksign lists documentoscopia at “R$ 4,50 cobrado por uso”; ZapSign lists a standalone digital certificate at “R$ 160 a R$ 260”, included from the Equipe plan.
6. Whether the price is published at all. Three of these four print their self-serve prices where anyone can read them. If a plan is “sob medida”, the quote is the product.

Validity is not what separates them

It is worth saying plainly, because comparison articles in this market often imply otherwise: none of these platforms is more legally valid than another. Validity in Brazil comes from the law — the Código Civil and art. 10 of MP 2.200-2/01, with its two routes of an ICP-Brasil certificate carrying a presumption of truth and any other means of proving authorship and integrity being admissible on the conditions the §2º sets out. We work through the statute, including the trailing clause of §2º that citations usually drop, in are electronic signatures legally binding?

What varies between vendors is not validity but evidence: the completeness of the audit trail and whether the finished file can be re-verified later. Compare that, and compare price. Do not let anyone sell you validity, which you already have.

Where Signatura fits

Signatura is priced the other way round from everything above, and that is the honest summary of the difference: per seat, with unlimited documents and no send meter at all. There is no monthly franchise, no per-document overage line, and no charge for the people who sign. If your volume is high and your team is small, that model is cheaper to run and far easier to forecast; if you send a handful of documents a month from many hands, a metered Brazilian plan will beat us and you should take it.

One caveat we would rather state than bury: our pricing is published in US dollars, not reais — from $24 per seat per month on the annual plan, with volume discounts, as shown on our pricing page. Comparing that number directly against a figure in R$ is comparing units rather than prices, so the comparison worth making is the structural one above: a 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: if a Brazilian transaction requires an ICP-Brasil certificate — the route that carries the presumption of art. 10, §1º — that needs an accredited certification authority within ICP-Brasil, which we are not. Several of the platforms above resell those certificates; we would rather say so than oversell.

Frequently asked questions

Which is the cheapest e-signature platform in Brazil?

At the entry position of each vendor’s own published pricing, D4Sign’s Starter and ZapSign’s Profissional both begin at R$ 39,90 a month for 20 documents a month, ahead of Clicksign’s Start at R$ 69 and Autentique’s Profissional at R$ 99. But the entry price answers a different question from the one most buyers are asking, because all four meter documents: at unlimited volume ZapSign’s Profissional is R$ 149,90 a month while Autentique’s Profissional is R$ 99 with documents unlimited from the start. Work out your monthly volume, then compare the plans that actually cover it.

Do these platforms charge per user or per document?

All four charge by document volume, and two of them charge for users as well. Clicksign publishes a “Preço por Usuário” of R$ 15 on its self-serve plans and caps them at 5 or 10 users; ZapSign includes 10 users on Profissional and 30 on Equipe without a per-user charge; D4Sign and Autentique both advertise unlimited users, with D4Sign excepting its Starter Ilimitado plan at 10. Nobody in this category charges the people who sign.

Is an electronic signature legally binding in Brazil without an ICP-Brasil certificate?

Yes, on the terms the statute sets. Art. 10, §2º of MP 2.200-2/01 admits other means of proving authorship and integrity, including certificates not issued by ICP-Brasil, “desde que admitido pelas partes como válido ou aceito pela pessoa a quem for oposto o documento”. An ICP-Brasil certificate carries a legal presumption under §1º; anything else is admissible and depends on not being challenged, or on the file being able to show authorship and integrity if it is. The full provision and what it excludes are in are electronic signatures legally binding?

Should a Brazilian company use a local platform or an international one?

It depends on which meter hurts you. The local platforms bill by document and are generous with headcount; the international ones bill by seat and meter sending as a secondary cap — the anatomy of that second model is in how to choose a DocuSign alternative. If you need an ICP-Brasil certificate, buy from someone who can issue or resell one. If you need predictable cost at high volume, price the per-seat tools too, and read our overview of electronic signature software if you are still working out what the category includes.
