Best European E-Signature Providers for Small Business (2026)

A small business e-signature provider is a service that lets a company with few staff sign and collect signatures on contracts online, with a published entry price and a stated eIDAS level (simple, advanced or qualified) that decides how much legal weight the signature carries.

How we rank these tools — 4-step process

1
European ownership, verified
The company is headquartered and incorporated in the EU, EEA, the UK, Switzerland or Israel, and processes customer data in Europe or Israel. A US parent company disqualifies a tool from this page regardless of where its servers are.
2
Category fit and hands-on review
What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.
3
Compliance and pricing check
GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.
4
Position on this page
Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Vendors can pay for more visibility, higher up on the review pages; it never affects whether a tool is listed. Editorial policy

Key takeaways

Skribble in Zurich is the only provider here that states all three eIDAS levels (SES, AES and QES) and has a free Starter plan that charges per signature.
sproof in Austria sells signature allowances: Single costs €15 per month for one user with 100 advanced and 10 qualified signatures per year, billed annually.
SignRequest in Amsterdam has the lowest entry price in the group, from about €7 per month with a free tier, but offers no qualified signatures.
Yousign in Paris starts from about €9 per month and is eIDAS compliant, with narrower QES coverage than Skribble.
FP Sign (Berlin) and inSign (Marzling) both publish €24.90 per user per month on a twelve-month term, and both charge extra for QES.

Two numbers decide most small business e-signature purchases: what the cheapest usable plan costs, and which eIDAS level the provider says it supports. This ranking orders seven European providers by those two facts as their own pages state them. Prices exclude VAT unless stated, and providers that only quote prices on request, such as Scrive, Namirial and Signicat, are left out because the entry price cannot be compared.

The 7 tools reviewed

#1 Skribble

Zurich, Switzerland Founded 2018 Starter free (pay per signature) / Team €23 / Pro €36 per user/month excl. VAT Free tier

Best for: Choosing SES, AES or QES per document in one account

Operating company. Skribble AG
Jurisdiction. Switzerland (adequacy decision, outside the EEA)
Where the data sits. Switzerland
Independent checks. QES, AES and SES; eIDAS and ZertES
Source code. Closed source
Replaces. DocuSign, Adobe Sign

Skribble AG in Zurich states all three eIDAS levels, SES, AES and QES, and complies with both eIDAS and the Swiss ZertES law. A small business that signs with Swiss and EU counterparties can therefore stay with one provider, and can pick the level per document: a routine NDA at SES, an employment contract at AES, a corporate document at QES.

The entry route is a free Starter plan that charges per signature, then Team at €23 and Pro at €36 per user per month, excluding VAT. Switzerland sits outside the EEA under an adequacy decision, so Swiss law governs hosting, and QES adds identity verification that the signer has to complete.

What Skribble does well

All three eIDAS levels on one platform
Free Starter plan, pay per signature
Covers both eIDAS and ZertES

Where Skribble falls short

Swiss, not EU, jurisdiction
QES identity check adds work for the signer

Standout feature. It is the only provider here where an NDA and a qualified document can be signed from the same free account.

#2 sproof

Puch bei Hallein (Salzburg), Austria Private free / Single €15/month (1 user, 100 AES + 10 QES per year) / Team €170/month (10 users, 1,200 AES + 120 QES per year), billed annually, excl. VAT / Enterprise on request Free plan for individuals, students and associations; 14-day free trial of paid plans

Best for: Low-volume users who want a known annual bill

Operating company. sproof GmbH
Jurisdiction. EU (Austria)
Where the data sits. Europe, in ISO 27001-certified data centres; hosting provider and country not named by sproof
Independent checks. ISO 27001 (stated by sproof); not itself on the Austrian EU trusted list — QES via integrated eID providers
Source code. Closed source
Replaces. DocuSign, Adobe Acrobat Sign

sproof GmbH, registered near Salzburg, prices by allowance instead of by seat. Single at €15 per month covers one user with 100 advanced and 10 qualified signatures per year, and Team at €170 per month covers ten users with 1,200 advanced and 120 qualified, both billed annually and excluding VAT. A free plan exists for private use, students and associations.

SES, AES and QES are all stated, and a REST API is available. sproof is not itself on the Austrian trusted list: qualified signing runs through the eID providers integrated into its hub. Hosting is given as ISO 27001-certified data centres in Europe, with neither country nor provider named, so a buyer should ask for both.

What sproof does well

Signature allowances published per plan
Free plan for private use and associations
SES, AES and QES stated, plus REST API

Where sproof falls short

100 advanced signatures a year is a hard cap on Single
Hosting country and provider not named

Standout feature. Signatures are counted, not only seats, which lets a small team know its yearly cost in advance.

#3 SignRequest

Amsterdam, Netherlands Founded 2014 Free tier / from about €7/month Free tier

Best for: The cheapest route when the other party must sign without friction

Operating company. SignRequest
Jurisdiction. EU (Netherlands)
Where the data sits. EU
Independent checks. eIDAS compliant
Source code. Closed source
Replaces. DocuSign, HelloSign

SignRequest in Amsterdam has a free tier and paid plans from about €7 per month, the lowest entry price in this group. It states eIDAS compliance, which gives signatures legal standing across the EU, and it processes data in the EU.

The limits are about level and depth. There is no qualified electronic signature, identity verification is thinner than at a specialist, and complex multi-party sequences have fewer workflow options than Yousign. For a small team that signs a handful of ordinary agreements per month, the free tier may be enough.

What SignRequest does well

Free tier and paid plans from about €7/month
eIDAS compliant, EU processing
Templates and API for small teams

Where SignRequest falls short

No QES available
Fewer workflow options for complex sequences

Standout feature. It has the lowest published entry price in this comparison.

#4 Yousign

Paris, France Founded 2013 From about €9/month Free trial

Best for: French and EU small businesses wanting eIDAS signing from a CRM or HR tool

Operating company. Youtrust SAS (Yousign)
Jurisdiction. EU (France)
Where the data sits. EU (France)
Independent checks. eIDAS compliant, qualified trust service provider
Source code. Closed source
Replaces. DocuSign, HelloSign

Yousign, operated by Youtrust SAS in Paris, starts from about €9 per month and states that it is eIDAS compliant and a qualified trust service provider. Its tool page does not break the levels down per plan, so a buyer who needs a specific level should ask which plan includes it.

Templates, bulk sending, workflow automation and an audit trail cover the daily need, and an API lets a CRM or HR system start the signing. QES coverage is narrower than Skribble's, identity verification is lighter than at Signicat, and the product is strongest in the French market.

What Yousign does well

Entry price from about €9/month
API, templates and bulk signing
French company with EU storage

Where Yousign falls short

Levels per plan not itemised on the tool page
QES coverage narrower than Skribble

Standout feature. Signing can start from the system that created the contract, not from a downloaded PDF.

#5 Autenti

Poznań, Poland Founded 2012 PRO €20/month billed annually (€30 monthly) / PREMIUM €35/month billed annually (€55 monthly), 1 seat, net of VAT / Corporate and Enterprise on request 14-day free trial, no credit card

Best for: Small businesses that also need proof a document was delivered

Operating company. Autenti S.A.
Jurisdiction. EU (Poland)
Where the data sits. EEA, in data centres subject to European law; country and operator not named by Autenti

Replaces. DocuSign, Adobe Acrobat Sign

Autenti S.A. in Poznań publishes seat prices: PRO at €20 per month billed annually (€30 monthly) and PREMIUM at €35 billed annually (€55 monthly), one seat each and net of VAT. A fourteen-day trial needs no card. Corporate and Enterprise prices are on request.

On the eIDAS side, Autenti is on the Polish EU trusted list for qualified electronic registered delivery and qualified validation, not for issuing signature certificates. QES on the platform comes from InfoCert, SimplySign or mSzafir. Hosting is given only as the EEA, with country and operator not named.

What Autenti does well

Published seat prices from €20/month annual
Qualified registered delivery on the trusted list
ISO/IEC 27001 and ISO 22301

Where Autenti falls short

Qualified status does not cover signature certificates
Hosting country and operator not named

Standout feature. The qualified status is for proving delivery and validation, not signing.

VAT; QES €1.50 per signature on the smaller plans Free plan: 1 user for 30 days, expires automatically, no credit card

Best for: German small businesses wanting a published price and German data centres

Operating company. FP Digital Business Solutions GmbH

QES costs €1.50 per signature on the smaller plans.

Documents sit in FP Sign's own cloud in BSI-certified German data centres, and the vendor states ISO 27001 and BSI C5. The operator of those data centres is not named, FP Sign is not on the German trusted list, and the provider behind QES goes unnamed. A free single-user plan runs for 30 days.

What FP Sign does well

Full price list published
All three eIDAS levels stated
German data centres, ISO 27001 and BSI C5 stated by the vendor

Where FP Sign falls short

Twelve-month term on the Business plan

inSign GmbH in Marzling sells inSign 365 at €24.90 per user per month billed annually or €26.90 monthly, excluding VAT, on a twelve-month minimum term. inSign connect (the API) and the enterprise editions are on request, and a free test account needs no card. The enterprise edition can be installed on-premise.

QES carries a surcharge that is not published and comes from a partner that inSign does not name. inSign is not on the German trusted list itself, and the hosting provider in Germany is not named. The company holds ISO 27001 and the BITMi labels "Software Hosted in Germany" and "Software Made in Germany".

What inSign does well

Seat price published, monthly option available
On-premise edition for enterprise
ISO 27001 and BITMi labels

Which eIDAS level does a small business need?

Most day-to-day agreements, such as quotes, NDAs and supplier terms, are handled with a simple or advanced signature. The advanced level ties the signature to the signer and detects later changes, which helps if a document is disputed. A qualified signature carries the same legal effect as a handwritten one across the EU and reverses the burden of proof.

Ask your lawyer which documents in your sector require QES. Among the providers here, Skribble and sproof state all three levels, FP Sign does too, and SignRequest states none above eIDAS compliance.

How do I compare entry prices fairly?

Compare the same unit. Skribble charges per signature on Starter, sproof counts allowances per year, FP Sign and inSign charge per user on a twelve-month term, and SignRequest and Yousign quote from about €7 and €9 per month. Prices exclude VAT where the providers say so.

Then add what the cheap plan omits: QES surcharges (€1.50 per signature at FP Sign), per-seat minimums and annual commitments. A twelve-month term at €24.90 per user is a larger commitment than a free tier.

What should I check about hosting and the company?

Check where documents are stored and which company is the contracting party. Yousign, SignRequest, FP Sign and inSign state hosting in France, the EU or Germany, Skribble in Switzerland, and sproof and Autenti only say Europe or the EEA, without a country. If your rule is EU hosting, ask for the country.

Also check who issues the qualified certificate. At Autenti QES comes from InfoCert, SimplySign or mSzafir, at sproof from integrated eID providers, and at inSign from an unnamed partner.

How do I switch from a paper process or another tool?

Start with the three documents you sign most often and rebuild them as templates. Most providers here support templates, and a template saves more time than any other feature. Keep the signed PDFs and audit trails from the old tool, because they remain your evidence.

Run a pilot with one client who is used to signing online before you roll out to everyone, and tell counterparties in advance that the email will come from a new sender.

When should a small business not pay for e-signature software?

When you sign fewer than a handful of documents a year, a free tier such as SignRequest's or sproof's private plan can cover it. If a document needs a notary or a wet-ink signature by law, no e-signature tool changes that.

Also pause if the plan requires twelve months up front and your volume is uncertain. Pay-per-signature or a free trial first protects you from paying for seats you do not use.

How we selected and ranked these 7 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company register or the vendor's own legal notice rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are.

Feature verification (weight: 40%). We check each capability against the vendor's own documentation and product pages, and record what the tool does rather than what the category is assumed to include.
Ease of adoption (weight: 30%). Integrations, published API access, trial availability and how much configuration stands between signing and a usable result.
Value and transparency (weight: 30%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. We weigh what a buyer gets for the entry price, not the headline feature count.
Editorial review. Every page is researched and drafted with AI assistance, and the compliance and pricing claims are checked against the vendor's documentation before it is published under the founder's editorial responsibility. The three weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Vendor-reported outcomes — ROI figures, margin uplift, time saved — are labelled as vendor claims wherever they appear on this page. We have not audited them, and neither has anyone else who quotes them. Read our full editorial process for how pages are re-verified.

Frequently asked questions

Which European e-signature provider is cheapest?

SignRequest has the lowest entry price in this group, from about €7 per month with a free tier. Skribble's Starter plan is free and charges per signature.

Which providers state qualified electronic signature support?

Skribble, sproof and FP Sign state SES, AES and QES. inSign offers QES at a surcharge through a partner, and Autenti QES through InfoCert, SimplySign or mSzafir.

Is an e-signature legally valid in the EU?

Under eIDAS an electronic signature cannot be denied legal effect only because it is electronic. A qualified signature has the same effect as a handwritten one, and the level you need depends on the document and the law that governs it.

Are these prices with or without VAT?

Skribble, sproof, FP Sign, inSign and Autenti state prices excluding VAT or net of VAT. SignRequest and Yousign give "from about" figures on their tool pages, so confirm at checkout.

Do these providers keep documents in the EU?

Yousign, SignRequest, FP Sign and inSign state EU or German hosting, Skribble hosts in Switzerland, and sproof and Autenti name only Europe or the EEA. Confirm the country in the data processing agreement.
