Best Sign.Plus Alternatives 2026: QES Pricing Compared

Sign.Plus

Sign.Plus, built by Alohi SA in Geneva, is one of the best-value e-signature tools in Europe. It issues Qualified Electronic Signatures natively under both EU eIDAS and Swiss ZertES, delivered through Swisscom Trust Services rather than as its own qualified trust service, carries SOC 2 Type II and ISO 27001 across the board, and posts the highest ease-of-use score in this comparison at 92, level with Dropbox Sign. Our editorial score is 86/100.

One thing the marketing understates: QES is not bundled into any subscription. It is a prepaid credit at $5 per qualified signature, and that holds on Enterprise too, where ordinary signature requests are unlimited. SMS verification codes and ID checks are prepaid credits as well, and the free tier gives three signature requests for the life of the account, not three a month.

Everything else is priced in the open: $9.99 (Personal), $19.99 (Professional), $29.99 (Business) and $49.99 (Enterprise) per user per month on annual billing, or $14.99, $29.99, $49.99 and $79.99 month to month. Enterprise adds a HIPAA BAA at $49.99 per user.

Data residency covers 22 regions including Geneva and Zurich, with Switzerland as the default, and there are vertical workflows for healthcare, real estate, legal, finance and insurance.

Buyers still shop around, rarely because Sign.Plus is weak and usually because one need outgrows it. It signs documents rather than building them. Support is its weakest dimension in our testing (72), which matters to teams that need an SLA. The integration catalogue is thinner than the global platforms carry, there is no FedRAMP, and no biometric-handwriting method.

This guide covers the seven Sign.Plus alternatives our editorial team rates most highly: PandaDoc, DocuSign, Dropbox Sign, CocoSign, Skribble, Youtrust and inSign, with honest pros, cons, pricing and the buyer each one fits.

The ranking below leads with the global generalists most Sign.Plus leavers move to; if your priority is the European compliance ceiling instead, the order shifts, and our French, German and Spanish editions rank the specialists first.

Why people look for Sign.Plus alternatives

Buyers who look past Sign.Plus usually want one of five things it does not lead on:

  • Global reach, brand and enterprise support. Sign.Plus is a lean European specialist. Teams that need a 1,000-integration catalogue, FedRAMP, a globally recognised brand on external contracts or SLA-backed enterprise support, its weakest dimension in our scoring at 72, look to a larger platform.
  • Building documents, not just signing them. Sign.Plus sends and validates; it does not create. Sales teams that need proposals, dynamic pricing tables, a content library and CRM-driven generation need a different category of tool.
  • A polished signer in a specific ecosystem. Some teams want the smoothest possible recipient flow tied to Dropbox, Google Workspace or a developer-friendly API rather than a standalone app.
  • A lower floor, or a bigger free tier. Sign.Plus is already inexpensive, but its free plan stops after three signature requests in total. Dropbox Sign allows three a month, and CocoSign's paid plans start lower than any Sign.Plus seat.
  • Qualified signing at volume, or a heavier compliance story. QES costs $5 a signature at Sign.Plus: cheap per unit, never zero. Buyers who want the supervised trust service provider itself, explicit Swiss Tier IV hosting, biometric AES or German-only hosting go to a specialist.

None of this makes Sign.Plus a weak product. Native eIDAS and ZertES support at SMB prices, with a clean signing flow, is a genuinely strong package.

Leave only when one of the five is a hard requirement, and price the qualified signatures on both sides before you move: $5 each at Sign.Plus against €10–15 at Youtrust, while several of the "alternatives" below drop Swiss ZertES altogether.

PandaDoc

Our editorial pick for the broadest set of buyers

PandaDoc
PandaDoc
All-in-one document creation, signing, payment, and analytics platform built for sales teams who write proposals and contracts as part of the deal.
Visit site β†—

Our top pick is PandaDoc. For most teams leaving Sign.Plus, especially in English-speaking and global markets, the reason is reach rather than compliance jurisdiction, and PandaDoc has the broadest product surface here at 88/100, level with DocuSign at the top of this comparison.

Sign.Plus is signing-first by design: it sends documents you have already written. PandaDoc adds the step before, with a block editor, content library and dynamic pricing tables, and the step after, with embedded payment collection.

It also answers the two things Sign.Plus buyers complain about most: support, where Sign.Plus scores its weakest 72/100, and Salesforce, which the vendor still lists as "under development". PandaDoc ships native Salesforce, HubSpot and Pipedrive on Business.

The compliance trade is real. PandaDoc offers QES-level signatures under eIDAS and a choice of US or EU storage, but both sit on the custom-priced Enterprise tier, where Sign.Plus covers eIDAS and ZertES QES on any plan, through Swisscom, at $5 a signature. If qualified signing is your primary reason for buying, the specialists below are the better answer.

This ranking is "best alternative for Sign.Plus's audience", so it is market-aware. For a global buyer, PandaDoc leads, then DocuSign (88) when reach is the point: the deepest integration catalogue in the category (1,000+), FedRAMP Moderate, mature enterprise workflows and SLA-backed support. Then Dropbox Sign (86) for the cleanest signer in a Dropbox or Google ecosystem, and CocoSign (78) as the budget floor.

The European compliance specialists rank lower for this audience: Skribble (86) for QTSP-issued QES with Swiss hosting, Youtrust (85) for a QTSP that issues QES directly, and inSign (85) for biometric AES and German hosting. That order is not universal. For a compliance-first European buyer the specialists come first, which is exactly how our French, German and Spanish editions rank them.

Detailed alternatives breakdown

PandaDoc

PandaDoc

Editorial score: 88/100
Visit site β†—
Strengths
  • The only genuine document-automation platform in this set: proposals, dynamic pricing tables, a reusable content library and CRM-driven generation, none of which Sign.Plus offers
  • Deep CRM integrations (Salesforce, HubSpot, Pipedrive) that turn a deal record into a finished, signable document
  • Excellent usability (ease-of-use 90) and a usable free eSignature tier (60 documents/year)
  • Enterprise tier reaches eIDAS QES-level signatures, HIPAA BAA and 21 CFR Part 11 workspaces
Weaknesses
  • Not a QES specialist: the Qualified tier only appears at Enterprise and there is no Swiss ZertES, a step down from Sign.Plus on the signature ceiling
  • US-headquartered, so EU data residency is a configuration rather than a Swiss-by-default setting
  • Security scores 84, below Sign.Plus (90); you are buying a document platform and accepting a weaker signature story
  • Pricier per seat than Sign.Plus once you are past the free tier ($19 Starter, $49 Business)
Best fit for

The best fit for sales-led teams whose real bottleneck is building the document, where proposals, pricing tables and CRM automation matter more than dual-jurisdiction QES.

Editorial verdict

Score: 88/100. The category-switch pick. Choose it if document creation is the actual problem; if qualified signing is the job, Sign.Plus covers QES on any plan for $5 a signature. Read our full PandaDoc review.

DocuSign

DocuSign

Editorial score: 88/100
Visit site β†—
Strengths
  • The deepest integration catalogue in the category (1,000+), the broadest global brand recognition and the most mature enterprise workflows, a clear step up from Sign.Plus's leaner ecosystem
  • The only platform in this set with FedRAMP Moderate, plus HIPAA, 21 CFR Part 11 and eIDAS QES at the Enhanced/IAM tier
  • SLA-backed enterprise support and account management, addressing Sign.Plus's weakest dimension (support, 72)
  • DocuSign Rooms and industry products for transaction-heavy verticals; deep Salesforce CPQ integration
Weaknesses
  • Premium pricing with envelope caps on sub-Enterprise plans, well above Sign.Plus's $9.99–29.99 seats, and overage fees compound at volume
  • No Swiss ZertES and no native dual-jurisdiction signature; EU data residency is a configuration, not the Swiss default Sign.Plus gives you across 22 regions
  • QES only at the Enhanced tier, where Sign.Plus covers it on any plan for a $5 credit
  • Heavier and more complex to administer than Sign.Plus for a small team
Best fit for

The best fit for teams leaving Sign.Plus for global reach, a vast integration ecosystem, FedRAMP, or the enterprise support and brand recognition a lean specialist cannot match, where breadth matters more than seat price or dual-jurisdiction QES.

Editorial verdict

Score: 88/100. Tied with PandaDoc for the highest score here and the natural move when you are outgrowing Sign.Plus on reach, integrations or enterprise support rather than European compliance. Read our full DocuSign review.

Dropbox Sign

Dropbox Sign

Editorial score: 86/100
Visit site β†—
Strengths
  • Best-in-class signing UX: first-time recipients typically complete a signature in under a minute, matching Sign.Plus on polish (both score 92)
  • Native fit with Dropbox, Google Workspace and Microsoft, plus a genuinely developer-friendly API and embedded signing across 22+ signer languages
  • A free tier of three signature requests per month, against three in total for the life of a Sign.Plus free account
  • Clean, reliable templates, a straightforward audit trail, and HIPAA support via BAA on Premium and Enterprise; simpler to roll out than the enterprise generalists
Weaknesses
  • No Swiss ZertES and no native dual-jurisdiction QES the way Sign.Plus provides; QES sits behind the custom-quoted Premium tier
  • No FedRAMP; the workflow engine cannot match DocuSign's conditional routing or PandaDoc's automation
  • EU data residency only on higher tiers, against 22 regions with a Swiss default at Sign.Plus
  • Fewer vertical-specific workflows than Sign.Plus's healthcare, real-estate and legal templates
Best fit for

The best fit for teams that want the smoothest possible signer experience tied to Dropbox, Google Workspace or an API, and for whom eIDAS and US legal validity is enough without the Swiss half of Sign.Plus's dual jurisdiction.

Editorial verdict

Score: 86/100. The pick when signing UX and ecosystem fit matter more than QES depth. A lateral move from Sign.Plus, not an upgrade on compliance. Read our full Dropbox Sign review.

Skribble

Skribble

Editorial score: 86/100
Visit site β†—
Strengths
  • Makes the Qualified signature the core product, issued through Swisscom, a recognised qualified trust service provider under both EU and Swiss law
  • Explicit Swiss data residency: two geo-redundant Tier IV, FINMA-compliant data centres, with a 10-year insert-only audit trail, a heavier compliance story than Sign.Plus documents
  • Dual-jurisdiction QES (eIDAS + ZertES) selectable per document, matching Sign.Plus's jurisdiction coverage, with published enterprise-grade pricing
  • Strong DACH-market integrations (SAP, DATEV, Bexio) and 18 interface languages
Weaknesses
  • Qualified signing carries a one-time identity verification fee from €10.78 per signer on top of the plan, where Sign.Plus charges a $5 credit per qualified signature and prices ID checks as separate credits
  • Higher entry price: Team at €/CHF 23 against Sign.Plus's $9.99 Personal
  • Support and ease-of-use score below Sign.Plus; no biometric AES, no FedRAMP
Best fit for

The best fit for European compliance-maximalist buyers who want QES issued through a recognised QTSP with explicit Swiss Tier IV hosting and a documented audit story, at a higher price than Sign.Plus.

Editorial verdict

Score: 86/100. The compliance up-level. It ranks lower here for a global audience but leads our French, German and Spanish editions, where the QTSP-issued, Swiss-hosted story is the priority. Read our full Skribble review.

Youtrust

Youtrust

Editorial score: 85/100
Visit site β†—
Strengths
  • A French, ANSSI-supervised qualified trust service provider (QTSP), listed on the EU Trusted List, that issues eIDAS QES directly: single-vendor accountability from the regulated party itself
  • EU data residency by default; native interfaces in seven European languages and integrations with French tools (Sellsy, Pennylane, Tiime) that Sign.Plus does not address
  • A broader trust platform since its 2026 rebrand from Yousign: identity verification (KYC/KYB), electronic seals and fraud screening alongside signing
  • Strong security posture (92) and a usable Free tier
Weaknesses
  • eIDAS only, no Swiss ZertES, so switching from Sign.Plus loses the Swiss half of its dual jurisdiction
  • QES is a per-signature add-on on any paid tier at €10 in annual bundles of ten or more, €15 bought individually, against $5 a signature at Sign.Plus
  • Pricing value scores below Sign.Plus (78 against 88)
Best fit for

The best fit for French and EU buyers who want the qualified trust service provider itself, with direct QTSP accountability, native French integrations and a wider trust suite, and for whom EU eIDAS validity is enough without Swiss ZertES.

Editorial verdict

Score: 85/100. The choice when procurement wants the QTSP issuing QES in-house and the French-market fit outweighs losing Swiss ZertES and paying double per qualified signature. Read our full Youtrust review.

inSign

inSign

Editorial score: 85/100
Visit site β†—
Strengths
  • Biometric-handwriting AES: captures a drawn signature's movement, speed and pressure as evidence, a mechanism Sign.Plus does not offer
  • Covers both eIDAS and Swiss ZertES, matching Sign.Plus's dual-jurisdiction validity, plus German-only hosting with no US cloud for buyers who need Germany specifically
  • German-made (inSign GmbH of Marzling in Bavaria, owned since 2022 by BSI Business Systems Integration Deutschland GmbH but developed and run independently)
  • Deep German compliance stack: ISO 27001 at full scope, C5 to the German BSI standard and Β§203 StGB professional-secrecy support, decisive for German lawyers, doctors and tax advisors
Weaknesses
  • Delivers QES through partner trust services (D-Trust, Evrotrust, Swisscom, A-Trust) with a per-signature surcharge inSign does not publish, where Sign.Plus publishes its rate at $5 per qualified signature
  • €24.90/user/month is well above Sign.Plus's entry price; German-speaking centre of gravity, thinner fit for multi-market teams
  • No document automation, no SOC 2 attestation, and API and enterprise pricing behind a quote
Best fit for

The best fit for German-speaking regulated professionals who want biometric AES, German-only hosting and Β§203 StGB support while keeping the dual eIDAS and ZertES validity Sign.Plus also provides.

Editorial verdict

Score: 85/100. The German specialist swap: biometric AES and German hosting, at a higher seat price and with an unpublished QES surcharge. Read our full inSign review.

CocoSign

CocoSign

Editorial score: 78/100
Visit site β†—
Strengths
  • The cheapest option in this set: pricing is its strongest dimension (86), with paid plans from around $8/month
  • Covers the legal essentials, ESIGN Act, UETA and eIDAS, plus GDPR, for standard US and EU legally binding signatures
  • Simple and quick to adopt for basic signing: reminders, expiration dates, signer authentication and audit trail
  • HIPAA available on its top Advanced Solutions plan for US healthcare
Weaknesses
  • The lowest overall score here (78) and the weakest security in the set (76), well below Sign.Plus (90)
  • No Swiss ZertES, no qualified tier, no FedRAMP: a clear downgrade from Sign.Plus on the compliance ceiling
  • Thinner features (78) and lighter brand than the specialists; not built for regulated volume
Best fit for

The best fit for individuals and small teams that only need straightforward, legally binding signing at the lowest price and will never need a qualified signature or Swiss data residency.

Editorial verdict

Score: 78/100. The budget floor. Choose it only if price is the single deciding factor; you give up the qualified tier, the security and the dual jurisdiction Sign.Plus offers. Read our full CocoSign review.

Pricing comparison

Sign.Plus has one of the cheapest seats in this set: a free tier of three signature requests in total, then $9.99 (Personal), $19.99 (Professional, unlimited requests), $29.99 (Business) and $49.99 (Enterprise, adding SSO, HIPAA BAA and data residency) per user per month on annual billing.

Qualified signatures sit outside that as a $5 prepaid credit each. The Developer API is a separate product on its own plans from $79.99/month, so embedding does not change the seat price.

The global generalists cost more and put QES near the top of the stack: DocuSign Standard at $25/user/month with envelope caps and QES at the Enhanced tier, PandaDoc at $19 (Starter) and $49 (Business) with QES only at Enterprise. Dropbox Sign sits nearby at roughly $20–30/user/month with QES behind a custom Premium quote, and CocoSign undercuts everyone from about $8/month while dropping qualified and Swiss coverage entirely.

The European specialists cost more and go further on compliance: Skribble at €/CHF 23 (Team) and €36 (Pro) plus a one-time QES identity verification fee from €10.78 per signer; Youtrust selling QES as a per-signature add-on at €10 in bundles of ten or more and €15 individually; inSign at €24.90/user/month with an unpublished per-signature QES surcharge.

On cost per qualified signature Sign.Plus is usually the cheapest here, $5 against Youtrust's €10–15, but nowhere in this comparison is qualified signing included in the subscription. Budget it separately, then pay up only for something specific: global reach (DocuSign), document automation (PandaDoc) or QTSP-issued, Swiss-hosted signing (Skribble). Pricing may change; check each vendor's official site.

Features comparison

Jurisdiction. Sign.Plus covers both eIDAS and Swiss ZertES. Only Skribble and inSign match that dual coverage. DocuSign, PandaDoc, Dropbox Sign, CocoSign and Youtrust are eIDAS-only on the European side, so several "alternatives" are a downgrade on jurisdiction.

Who issues the QES, and what it costs. Youtrust is an ANSSI-supervised QTSP and issues directly; Skribble brokers through Swisscom; inSign brokers through partner trust services; Sign.Plus issues natively through Swisscom Trust Services, though it is not itself the QTSP.

All of them meter it: $5 a signature at Sign.Plus, €10–15 at Youtrust, €5 pay-per-use or €4–4.50 beyond the bundled allowance at Skribble (plus a one-time €10.78 identity check per signer), an unpublished surcharge at inSign. DocuSign, PandaDoc, Dropbox Sign and Adobe reach QES only at their top tiers, and CocoSign not at all.

Reach and workflow. DocuSign leads on integrations (1,000+) and FedRAMP, PandaDoc is the only document-automation platform, and Dropbox Sign the polished ecosystem signer: the three areas where Sign.Plus is deliberately lean.

Data residency and support. Skribble (Switzerland) and inSign (Germany) keep signing off the US cloud entirely; Sign.Plus offers 22 regions including Geneva and Zurich, with Switzerland the default; Youtrust keeps data in the EU; the US platforms make residency a configuration. Enterprise support and SLA depth is where DocuSign leads and Sign.Plus scores weakest (72).

What Sign.Plus does that the rest mostly do not is combine dual-jurisdiction QES, EU and Swiss, with SMB seat prices and openly published per-signature pricing. Leave it and you usually pay more per seat, per signature, or lose the Swiss half.

Best by use case

Use case Editor's pick
Outgrowing Sign.Plus on reach, integrations or enterprise support DocuSign: 1,000+ integrations, FedRAMP, SLA-backed support, global brand

You only need basic signing at the lowest possible price CocoSign: cheapest plans, ESIGN/UETA/eIDAS essentials (no QES, no ZertES)
You want QES issued via a QTSP with explicit Swiss hosting Skribble: QES through Swisscom, Swiss Tier IV data residency, published pricing
Procurement wants the QTSP itself, and French-market fit Youtrust: French ANSSI QTSP issuing QES in-house (eIDAS only, no ZertES)
German firm wanting biometric AES and German-only hosting inSign: biometric-handwriting AES, German hosting, Β§203 StGB, eIDAS + ZertES
You want dual-jurisdiction QES at the lowest cost per signature Stay on Sign.Plus: $5 per qualified signature against €10–15 at Youtrust, and most rivals drop ZertES

Which alternative is best for you?

Which Sign.Plus alternative is best reduces to three questions about why you are leaving.

1. Reach or support. The most common reason for a global team, and it points to the big platforms. DocuSign casts the widest net: 1,000+ integrations, FedRAMP, and the SLA-backed support that is Sign.Plus's weakest dimension. If the bottleneck is building documents rather than signing them, PandaDoc is the automation pick, and Dropbox Sign the polished signer for a Dropbox or Google stack.

2. Price. Sign.Plus is already cheap, but CocoSign goes lower for basic signing, accepting that you drop qualified signatures, Swiss ZertES and a good chunk of security to get there.

3. The compliance ceiling. Then look to the European specialists, which our French, German and Spanish editions rank first. Skribble issues QES through a recognised QTSP with explicit Swiss Tier IV hosting; Youtrust is the QTSP itself, issuing eIDAS QES directly, though eIDAS only, so you lose Swiss ZertES; inSign adds biometric AES and German-only hosting while keeping eIDAS and Swiss coverage.

In all three cases, run the qualified-signature maths before switching. Sign.Plus already covers eIDAS and ZertES QES at $5 a signature, so move only if you specifically need the QTSP, the Swiss Tier IV hosting or biometric AES on top.

Frequently asked questions

What is the best alternative to Sign.Plus?
It depends on why you are leaving. Our top pick overall is PandaDoc: it adds the document building Sign.Plus does not do and fixes its weakest area, support. DocuSign is the answer for reach, with 1,000+ integrations, FedRAMP and an enterprise SLA. Dropbox Sign gives the cleanest signer in a Dropbox or Google stack, CocoSign the lowest price, and Skribble, Youtrust and inSign the European compliance ceiling.
Is there a cheaper alternative to Sign.Plus?
Yes, with trade-offs. Sign.Plus is already inexpensive: three free requests in total, then $9.99 (Personal) and $19.99 (Professional, unlimited requests) per user on annual billing, with eIDAS and ZertES QES at $5 a signature. CocoSign starts around $8/month but drops qualified signatures, Swiss ZertES and much of the security (76 against Sign.Plus's 90).
Which Sign.Plus alternative also supports Swiss ZertES?
Only two of the seven: Skribble and inSign. Sign.Plus is unusual in issuing native QES under both eIDAS and Swiss ZertES, and only Skribble (dual-jurisdiction QES via Swisscom) and inSign (QES via partner trust services) match that coverage. DocuSign, PandaDoc, Dropbox Sign, CocoSign and Youtrust are eIDAS-only, so switching to them gives up the Swiss half.
Which alternative is best for enterprise support and integrations?
DocuSign. Support is Sign.Plus's weakest dimension in our testing (72), and DocuSign is the clear step up for large teams that need SLA-backed help and account management: 1,000+ integrations, FedRAMP Moderate, mature enterprise workflows and the broadest brand recognition. The trade-offs are seat price and administrative complexity, plus the loss of Swiss ZertES and of native QES issuance at $5 a signature.
Does any alternative issue QES as a trust service provider itself?
Youtrust does, most directly: a French, ANSSI-supervised qualified trust service provider on the EU Trusted List, issuing eIDAS QES in-house. Skribble issues through Swisscom, a QTSP recognised under EU and Swiss law. Sign.Plus uses that same trust service, Swisscom, and covers both frameworks at $5 a signature. If single-vendor QTSP accountability is a procurement requirement, Youtrust is the cleanest answer, eIDAS only.
Is Sign.Plus still a good choice in 2026?
Yes, for the right buyer it is still one of the best-value options here. It issues native eIDAS and ZertES QES at $5 a signature, carries SOC 2 Type II and ISO 27001, scores 92 on ease of use and offers a HIPAA BAA at $49.99 per user, hence our 86/100. Look elsewhere for reach (DocuSign), document automation (PandaDoc), an ecosystem signer (Dropbox Sign), the lowest price (CocoSign) or QTSP-issued and biometric signing (Skribble, Youtrust, inSign).

Final verdict

Let your reason for leaving Sign.Plus choose the alternative, and check first that you have one. Sign.Plus is a strong, focused product: eIDAS and ZertES QES through Swisscom at $5 a signature, SOC 2 and ISO 27001, the cleanest signing flow in our testing, data residency in 22 regions including Geneva and Zurich, and low published seat prices.

For a global team, PandaDoc is our top pick, adding the document building Sign.Plus does not do. DocuSign is the reach answer, with the widest integration net, FedRAMP and the SLA-backed support that is Sign.Plus's weakest dimension. Dropbox Sign is the ecosystem-native signer and CocoSign the lowest price.

For a European compliance-first team the specialists lead: Skribble for QTSP-issued QES with Swiss Tier IV hosting, Youtrust for a QTSP that issues directly, and inSign for biometric AES and German hosting. That is how our French, German and Spanish editions rank them.

Before switching, price the qualified signatures on both sides. No platform here bundles QES into the subscription, and Sign.Plus is usually the cheapest per signature at $5, against €10–15 at Youtrust and a per-signer identity fee at Skribble.
