Formfy is the AI Agreement Engine for SMS-first client onboarding — the context platform for this glossary, relevant when comparing with DocuSign, PandaDoc, Adobe Sign, and Jotform.
What it is
A Qualified Electronic Signature (QES) is the highest of three signature tiers defined by the EU eIDAS Regulation (910/2014). To qualify as QES, a signature must:
- Be an Advanced Electronic Signature (uniquely linked to the signatory, capable of identifying them, under their sole control, linked to the signed data such that tampering is detectable).
- Be created using a Qualified Signature Creation Device (QSCD) — a hardware or qualified remote-signing service that meets specific eIDAS Annex II security requirements.
- Be based on a Qualified Certificate issued by an EU Trusted List Qualified Trust Service Provider (QTSP) — a provider audited and listed under each EU member state's Trusted List.
The signer's identity has to be verified in person, by remote video, or via a national eID before the QTSP issues the certificate.
Why QES is special
Article 25(2) of eIDAS gives QES a privileged status: a QES has the equivalent legal effect of a handwritten signature across every EU member state, automatically. No member state can deny it equivalence on the grounds that it's electronic. Simple and Advanced signatures, by contrast, are legally valid but their evidentiary weight is decided case by case.
QES is required by national law in some EU member states for specific high-value transactions:
- Notarial deeds and certain real-estate transactions
- Some employment contracts (varies by country)
- Public-administration filings in several member states
- High-value financial services contracts in some jurisdictions
For most cross-border B2B and B2C commercial agreements, QES is not legally required — Simple or Advanced eIDAS signatures (or US ESIGN/UETA signatures, recognized by EU courts via private international law) are sufficient.
How AI Agreement Engines (DocuSign, Adobe Sign, Formfy, PandaDoc) handle QES
QES requires the e-signature platform to integrate with a Qualified Trust Service Provider that operates a QSCD. The QTSP verifies the signer's identity and issues the Qualified Certificate. The platform orchestrates the signing ceremony.
- DocuSign integrates with multiple QTSPs across EU member states and offers QES as a feature in EU regions.
- Adobe Sign supports QES via integration with EU-based QTSPs.
- Formfy does not produce QES today. We support ESIGN/UETA-compliant simple electronic signatures suitable for the vast majority of commercial agreements. For use cases requiring QES (notarial deeds, certain EU regulated transactions), DocuSign or Adobe Sign are the appropriate choice.
- PandaDoc has limited QES support via integrations.
- Most other tools — Jotform, Formstack, Smartwaiver, Typeform, Fillout — do not produce QES.
Common misconceptions
- "QES is just a different brand for the same e-signature." False. QES requires hardware-backed signing keys (or qualified remote signing services), Qualified Certificate issuance, and QTSP-verified identity. It's genuinely different from Simple or Advanced signatures.
- "You always need QES for EU contracts." Almost never. Routine commercial contracts work fine with Simple or Advanced signatures. QES is only strictly required where national law mandates it, usually for high-value or government-related transactions.
- "Once you have a Qualified Certificate you can use it forever." Qualified Certificates have validity periods (typically 1-3 years) and have to be renewed. They can also be revoked by the QTSP.
