Choose Certyneo if…
- Vous voulez une API REST dès le plan Standard (19 €/mois) plutôt qu'au plan Premium (40 €/mois).
- Vous avez besoin d'un plan gratuit permanent pour tester ou pour de très faibles volumes.
- Votre tarification par utilisateur émetteur devient un frein — Certyneo facture par enveloppe.
- Vous opérez en zone OHADA et avez besoin de templates juridiques adaptés au droit OHADA.
- Vous voulez une interface dans 41 langues plutôt que 10.
Stay with Yousign if…
- Vous voulez exclusivement de la signature SES sans besoin d'API ou de plan gratuit.
- Vous avez des contraintes contractuelles avec OVHcloud spécifiquement (politique d'achat IT française).
- Vous utilisez déjà l'écosystème de connecteurs no-code Yousign et la migration n'apporterait pas de gain net.
Frequently asked questions
Yousign and Certyneo are both French — what is the real difference?
Both solutions are French, hosted in the EU, and eIDAS compliant. Practical differences: (1) Certyneo charges per envelope on paid plans, Yousign charges per sending user; (2) Certyneo includes REST API from 9 €/month, Yousign reserves it for 40 €/month; (3) Certyneo offers a permanent free plan, Yousign only a 14-day trial; (4) Certyneo covers 41 interface languages, Yousign covers 10.
Can I migrate my Yousign envelopes to Certyneo?
Yes. Yousign export provides signed PDFs with a proof certificate. Our assisted migration offer imports these archives into Certyneo and reconstructs equivalent templates. The continuity of the legal value of archived envelopes is preserved — each Yousign PDF remains legally enforceable.
If Yousign and Certyneo are equivalent in compliance, why switch?
Compliance (eIDAS, GDPR, EU hosting) is only a prerequisite — not a differentiator. The choice is made based on pricing model, API access, free plan, and language coverage. If your use case is only a few envelopes per month in French, Yousign may be suitable.
Is Yousign cheaper for micro-businesses?
Not necessarily. Yousign Starter at €9 excl. tax/user/month bills each sender. If you have 3 people sending contracts, that's €27/month minimum. Certyneo Personnel at €9/month includes one user and bills envelopes beyond the plan, without charging each sending user.
Yousign is hosted in France (OVHcloud), Certyneo in Germany (IONOS) — what GDPR impact?
None for GDPR compliance: both hosts are in the European Union, subject to GDPR and outside the US Cloud Act. The difference lies in operational resilience (IONOS and OVHcloud have different SLA histories) and local certifications (HDS for healthcare is more mature on OVH's side). For the majority of use cases, the choice is neutral.
How much does the REST API cost at Yousign vs Certyneo?
At Yousign, the REST API is reserved for the Premium plan at €40 excl. tax/user/month — a team of 5 people pays €200 excl. tax/month minimum to access it. At Certyneo, the REST API + webhooks + official SDKs are included from the Standard plan at €19/month (10 users included), roughly 10× cheaper for the same integration need.
Is bulk multi-signer sending available at Yousign?
Yousign bulk sending exists via the API or CSV import, accessible on Premium plans (€40 excl. tax/user/month). Certyneo includes it from the Business plan (€39/month) with a no-code interface to send the same document to 100 recipients at once — useful for annual HR contracts, updated terms of service, or mass NDAs.
Does Yousign offer OHADA legal templates?
No. Yousign primarily targets the EU-EEE market. Certyneo covers EU jurisdictions + OHADA (West and Central Africa: 17 countries — Senegal, Côte d'Ivoire, Cameroon, etc.) with templates adapted to OHADA law and accepts Mobile Money (Orange Money, Wave, MTN) via CinetPay. Relevant for companies with African subsidiaries.
