Simple electronic signature
Suited to low-risk documents. Fast to deploy with lighter evidence.
Digital Identity & Compliance
Smooth customer journeys, solid evidence — vendor-neutral by design
Electronic Signature Integration
We integrate eIDAS workflows into your systems: provider selection, API, evidence packages, and archiving. Nuvelia remains neutral across leading European platforms.
Independent integrator: from QTSP selection to API, evidence packages, and archiving — we do not resell signature licenses.
Your project likely fits one of these scenarios
- First signature integrationChoosing eIDAS level, QTSP, and integration mode before the first production journey.
- Vendor migrationReversibility, envelope handover, and webhook continuity without cutting customer journeys.
- Remote multi-party journeySignature, identity, and back-office sync with reliable statuses and solid evidence.
- Compliance and dispute evidenceDocument × level matrix, timestamping, long-term PAdES, and probative archiving to scope.
- Recovery after failureLost webhooks, low completion rates, or weak evidence packages — audit and get back on track.

SES, AES, and QES — choosing the right level
Advanced electronic signature
Strong link to the signatory (OTP, certificate). Standard for B2B contracts and remote journeys.
Qualified electronic signature
Legal equivalent to handwritten signature. Required for certain regulated acts — with strong remote identification.
What usually blocks signature projects
- Wrong SES/AES/QES levelOver-qualified flows or evidence too weak for disputes — the risk/document matrix is missing.
- Lost webhooks and expired envelopesInconsistent statuses with no recovery — customers abandon or sign twice.
- Weak evidence packageMissing timestamping or PAdES B-LTA — proof fails under third-party scrutiny.
- PVID/GDPR and retentionRetention periods and legal bases poorly scoped — CNIL audit risk.
- Vendor lock-inNo reversibility clause — migration blocked by contract.
- eIDAS 2 roadmap gapEUDI Wallet, qualified archiving, and remote identification not planned in your roadmap.
What Nuvelia delivers

- Evidence file, timestamping, and long-term PAdES requirements
- PVID/GDPR scoping and proof convention wording

Outcome: Digital journeys integrated into the existing IS with controlled releases.
Insurance & telecom — secure subscription
Context: Online payment plus e-signature on a regulated funnel (PCI-DSS).
Nuvelia role: End-to-end technical design, external API integration, and data-flow security.
Outcome: Unified subscription journey ready to scale.
Complementary expertise
Regulatory priorities to embed in your roadmap
- eIDAS 2 and the European Digital Identity Wallet (EUDI Wallet)
- Qualified electronic archiving and long-term evidence
- Strong remote identification for qualified signatures
Common questions
Are you tied to one signature vendor?
No. We integrate multiple platforms (Universign, DocuSign, Docaposte, Yousign, etc.) based on your context — we do not resell licenses.
Can you help choose the right eIDAS level?
Yes — document risk matrix, dispute evidence, PVID, and long-term archiving are central to our scoping.
Can you fix a failed integration?
Yes: missing webhooks, low completion rates, weak evidence — we audit and get the project back on track.
How long for a first production journey?
A simple journey can go live in weeks depending on scope; deep integration with evidence and archiving typically takes 2–4 months — timeline confirmed after diagnostic, with no contractual commitment at this stage.
