Electronic signature for recruitment firms

Employment offer, search mandate, placement contract, candidate confidentiality agreement, staffing contract: coordinate three-way signature between recruitment firm ↔ client company ↔ candidate without mail or physical meeting. Compliant with the Labor Code, CNIL recruitment deliberations, eIDAS regulation and article 1366 of the Civil Code.

Use cases within a recruitment firm

From search mandate to final placement, each step involves at least two parties to coordinate: the firm rarely 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 less than 24 hours to start the search without waiting for mail return.

Three-way employment offer

Synallagmatic promise signed by the client company, countersigned by the firm (in its capacity as agent), then accepted by the candidate. Dual-channel OTP formally identifies each party and records the date of acceptance — binding within the meaning of article L1221-1 of the Labor Code.

Candidate confidentiality agreement (NDA shortlist)

Before sharing the confidential client brief with shortlisted candidates, an NDA protects the advertiser''s identity and position terms. Mobile signature in less than 2 minutes on the candidate''s side.

Placement contract & fees

Placement contract signed between the firm and the 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.

Staffing contract (temporary work, staffing, apprenticeship-track CDD)

Personnel provision: three-way contract between firm ↔ user company ↔ employee, signatures coordinated in a single envelope with common timestamp. Compliant with requirements L1251-42 et seq. of the Labor Code.

RPO & sourcing engagement letter

For Recruitment Process Outsourcing or fixed-fee sourcing missions: engagement letter specifying deliverables, KPIs and reporting. Advanced electronic signature for formal commitment from 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 three-way signature

A single envelope coordinates the client, firm and candidate. Configurable signature order (sequential or parallel), automatic reminder notifications, unique audit trail for all three parties.

Candidate mobile signature without account creation

Candidates — often in international mobility or employed — sign from their phone in less than 2 minutes, without downloading an application or creating an account. Essential to meet the 10-day acceptance deadline for an offer.

Audit trail admissible before the Labor Court

Each signed offer produces a timestamped certificate: candidate identity (email + SMS OTP), date of acceptance, SHA-256 fingerprint of the document. Admissible before labor courts in case of dispute over the offer or its acceptance.

Compliant with CNIL recruitment deliberation

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 offer validation on the ATS side, candidate status update at signature.

Probative value of the signed employment promise

Since the Court of Cassation ruling of 21 September 2017 (Cass. soc., n°16-20.103), the unilateral employment promise no longer constitutes an employment contract until the candidate accepts it — but acceptance immediately binds the employer. The acceptance date thus becomes the triggering event for all rights: probationary period, seniority, withdrawal.

Certyneo delivers for each signed promise a 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 timestamp binding on third parties
  • SHA-256 fingerprint of the promise as accepted, which demonstrates the absence of subsequent modification
  • Consultation log (how many times the candidate opened the promise before accepting)
  • Identification of the promise author on the client company side (countersigned signature)

This bundle of evidence protects the firm and client company against typical disputes ("I never accepted", "the promise was modified", "the acceptance date is later") and secures defence before the Labour Council.

Code du travail, CNIL recrutement et GDPR

Recruitment processes particularly sensitive data (CV, family situation, mobility, salary expectations) which require strict compliance framework.

Labour Code — placement & temporary work provision

Article L5321-1 governs paid placement activities, articles L1251-42 et seq. govern temporary work and personnel provision. Certyneo enables coordination of tripartite signatures required by these regimes and preserves documents with probative value.

CNIL Deliberation on recruitment (n°2002-017)

CNIL requires transparent candidate information, limited purpose to professional evaluation, storage duration proportionate. Certyneo hosts candidate data 100% within 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 hire date of the placed candidate — start of the guarantee period (typically 3-6 months). If departure occurs during the guarantee, the signed contract proves coverage and justifies the replacement service.

Frequently asked questions from firms

Is an electronically signed employment promise binding?

Yes. The employment promise can be signed on any medium (article 1366 of the Civil Code: electronic writing has the same probative force as paper writing). Since the Court of Cassation ruling of 21 September 2017 (n°16-20.103), it is the candidate''s acceptance that forms the contract — Certyneo traces this acceptance with a qualified timestamp binding before the Labour Council.

How do I manage tripartite signature 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 traces the three signatures with their respective timestamps.

How much time do we have to get an employment promise signed?

There is no legal deadline for signature on the client company side, but once the promise is sent to the candidate, they must accept it within a reasonable timeframe (typically 7 to 10 days according to 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 we sign a temporary work provision contract (temp work, staffing)?

Yes. Temporary work provision contracts (articles L1251-42 et seq. of the Labour Code) require tripartite signature: firm/agency ↔ user company ↔ employee. Certyneo coordinates this signature in a single envelope with common audit trail, compliant with mandatory provisions of 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 offer validation in your ATS, and candidate status update at promise signature. Full documentation at certyneo.com/developers.

How long are promises and contracts archived?

Our plans include 10-year archiving with probative value, the recommended duration for Urssaf audits, fee disputes and labour lawsuits. Documents and their audit trail remain downloadable at any time from the firm account, including after termination on request.

Does the candidate need to create a Certyneo account to accept a promise?

No. The candidate receives a direct link by email, opens the promise on their phone, verifies their number via an SMS code (OTP), signs with their name and finger — no application download, no account creation, no credit card. On the UX side, the experience is designed to create no friction in the 7-10 day acceptance window.
