Recruitment firms & executive search
Electronic signature for recruitment firms
Employment offer, search mandate, placement contract, candidate confidentiality agreement, personnel provision contract: coordinate tripartite signature between firm ↔ client company ↔ candidate without mail or physical meetings. Compliant with the French Labor Code, CNIL recruitment decisions, eIDAS regulation and article 1366 of the French Civil Code.
Use cases in a recruitment firm
From search mandate to final placement, each step involves at least two parties to coordinate: the firm almost never signs alone.
Search mandate (exclusive or non-exclusive)
Mandate signed with the client company before opening the assignment: scope, fees, exclusivity, replacement guarantee. Signature in under 24 hours to start the search without waiting for a mail response.
Tripartite employment offer
Bilateral promise signed by the client company, countersigned by the firm (as mandatary), then accepted by the candidate. Dual-channel OTP formally identifies each party and records the acceptance date — enforceable under article L1221-1 of the French Labor Code.
Candidate confidentiality agreement (NDA shortlist)
Before sharing the confidential client brief with shortlisted candidates, an NDA protects the employer's identity and job conditions. Mobile signature in under 2 minutes on the candidate side.
Placement contract & fees
Placement contract signed between the firm and client company: payment terms, replacement guarantee conditions (typically 3-6 months), termination terms. 10-year archiving with probative value for Urssaf audits and fee disputes.
Personnel provision contract (temp work, payrolling, bridge CDD)
Personnel provision: tripartite contract between firm ↔ user company ↔ employee, signatures coordinated in a single envelope with common timestamping. Compliant with articles L1251-42 et seq. of the French Labor Code.
RPO & sourcing engagement letter
For Recruitment Process Outsourcing or flat-fee sourcing missions: engagement letter specifying deliverables, KPIs and reporting. Advanced electronic signature for formal commitment by the client.
Why Certyneo for recruitment firms
Six garanties pensées pour la spécificité du recrutement : signature tripartite, mobilité candidat, GDPR strict et délais ultra-courts.
Native tripartite signature
A single envelope coordinates the client, firm and candidate. Configurable signature order (sequential or parallel), automatic follow-up notifications, unique audit trail for all three parties.
Candidate mobile signature without account creation
Candidates — often internationally mobile or in current employment — sign from their phone in under 2 minutes, without downloading an app or creating an account. Essential to meet the 10-day employment offer acceptance deadline.
Audit trail admissible in labor court
Each signed offer produces a timestamped certificate: candidate identity (email + SMS OTP), acceptance date, SHA-256 fingerprint of the document. Admissible before labor courts in case of dispute over the offer or its acceptance.
Compliant with CNIL recruitment decision
Données candidats chiffrées (TLS 1.3 + AES-256), hébergement 100 % UE, suppression sur demande, traçabilité des accès. Conforme à la délibération CNIL n°2002-017 et au GDPR pour le traitement des données personnelles en recrutement.
10-year archiving for Urssaf audits
Placement contracts and mandates are retained for 10 years with probative value, the recommended duration for Urssaf audits and fee disputes. Download the complete file at any time.
API & ATS integrations
Webhooks, Zapier and Make to connect Certyneo to your ATS (LinkedIn Talent Hub, Greenhouse, Lever, Teamtailor, Beetween, Flatchr). Automatic envelope creation upon job validation in your ATS, candidate status update upon signature.
Probative value of the signed employment offer
Since the French Supreme Court ruling of September 21, 2017 (Cass. soc., No. 16-20.103), the unilateral employment offer no longer constitutes an employment contract unless the candidate has accepted it — but acceptance immediately binds the employer. The acceptance date thus becomes the triggering event for all rights: probation period, seniority, withdrawal.
Certyneo delivers for each signed offer an audit certificate embedded in the PDF, which brings together all technical evidence:
- Candidate identity (verified email, phone confirmed by OTP)
- Exact date and time of acceptance — qualified timestamping, enforceable
- SHA-256 fingerprint of the offer as accepted, demonstrating the absence of later modification
- Consultation log (how many times the candidate opened the offer before accepting)
- Identification of the author of the offer on the client company side (countersigned signature)
This body of evidence protects the firm and client company against common disputes ("I never accepted", "the offer was modified", "the acceptance date is later") and secures the defense before labor court.
Code du travail, CNIL recrutement et GDPR
Recruitment handles particularly sensitive data (CV, family status, mobility, salary expectations) that require strict compliance framework.
French Labor Code — placement & personnel provision
Article L5321-1 regulates paid placement activities, articles L1251-42 et seq. regulate temporary work and personnel provision. Certyneo enables coordination of the tripartite signatures required by these regimes and preservation of acts with probative value.
CNIL recruitment decision (No. 2002-017)
CNIL requires transparent information to the candidate, a purpose limited to professional evaluation, proportionate retention period. Certyneo hosts candidate data 100% in the EU (Germany), encrypted in transit and at rest, with deletion on request.
GDPR — base légale & droits du candidat
Base légale = exécution de mesures précontractuelles à la demande du candidat (article 6.1.b du GDPR). Droits du candidat (accès, rectification, effacement, portabilité) implémentés nativement. DPA standard disponible au signup pour formaliser le rôle de sous-traitant.
Replacement guarantee & fees
Advanced electronic signature formally records the employment date of the placed candidate — start of the guarantee period (typically 3-6 months). In case of departure during the guarantee, the signed contract proves coverage and supports replacement service billing.
Frequently asked questions by firms
Is an electronically signed employment offer enforceable?
Yes. An employment offer can be signed on any medium (article 1366 of the French Civil Code: electronic writing has the same probative force as paper writing). Since the French Supreme Court ruling of September 21, 2017 (No. 16-20.103), it is the candidate''s acceptance that forms the contract — Certyneo records this acceptance with a qualified timestamping enforceable before labor court.
How do you manage tripartite signature between firm ↔ client ↔ candidate?
A single Certyneo envelope coordinates the three parties. You configure the signature order (for example: client first, then firm as countersignatory, then candidate), each party receives their link at the right step, and a unique audit trail records all three signatures with their respective timestamps.
How long do we have to get an employment offer signed?
There is no legal deadline for signature on the client company side, but once the offer is sent to the candidate, they must accept it within a reasonable timeframe (in practice 7 to 10 days per case law). Certyneo accelerates signature on the client side (often 2-4 hours) and candidate side (mobile, no account creation) to meet this deadline without pressure.
Les données des candidats sont-elles conformes au GDPR ?
Oui. Hébergement 100 % UE (IONOS Allemagne), chiffrement TLS 1.3 en transit et AES-256 au repos, isolation stricte des données par cabinet. La base légale du traitement est l'exécution de mesures précontractuelles à la demande du candidat (article 6.1.b GDPR). Une DPA standard est disponible et conforme à la délibération CNIL n°2002-017 sur le recrutement.
Can you sign a personnel provision contract (temp work, payrolling)?
Yes. Personnel provision contracts (articles L1251-42 et seq. of the French Labor Code) require tripartite signature: firm/agency ↔ user company ↔ employee. Certyneo coordinates this signature in a single envelope with shared audit trail, compliant with mandatory notices in article L1251-43.
What ATS integrations does Certyneo offer?
Native connectors via Zapier and Make for LinkedIn Talent Hub, Greenhouse, Lever, Teamtailor, Beetween, Flatchr. Our REST API enables automatic envelope creation upon job validation in your ATS, and candidate status update upon offer signature. Full documentation at certyneo.com/developers.
How long are offers and contracts archived?
Our plans include 10-year archiving with probative value, the recommended duration for Urssaf audits, fee disputes and labor claims. Documents and their audit trail remain downloadable at any time from the firm account, including after termination on request.
Must the candidate create a Certyneo account to accept an offer?
No. The candidate receives a direct link by email, opens the offer on their phone, verifies their number via SMS code (OTP), signs with their name and finger — without app download, account creation, or credit card. On the UX side, the experience is designed to create no friction within the 7-10 day acceptance window.
