Under French law, a quote signed by a client constitutes contract formation (article 1101 Civil Code): acceptance binds both parties on price, scope and deadlines. Advanced electronic signature guarantees that acceptance is attributable to an identified person and the document was not modified after signature.
Certyneo delivers for each signed quote or PO an audit certificate embedded in the PDF, which brings together all technical evidence:
- Signer identity (verified email, phone number confirmed by OTP)
- Qualified timestamp of acceptance — date enforceable against any late challenge
- SHA-256 fingerprint of the quote as presented, demonstrating absence of subsequent modification
- Consultation log (how many times the client opened the quote before signing)
- IP and rough geolocation of signer at time of acceptance
This body of evidence prevents classic disputes ("the quote had been modified", "I never received this version", "the PO is not from me") and secures amicable recovery as well as disputes before the commercial court.
