Under French law, a quote signed by a client constitutes contract formation (article 1101 of the Civil Code): acceptance binds both parties on price, scope and deadlines. Advanced electronic signature guarantees that acceptance is attributable to an identified person and that the document has not been modified after signing.
Certyneo delivers for each signed quote or PO an audit certificate embedded in the PDF, which groups all technical evidence:
- Signer identity (verified email, phone number confirmed by OTP)
- Qualified time-stamping of acceptance — date enforceable against any late dispute
- SHA-256 hash of the quote as presented, demonstrating the absence of subsequent modification
- Consultation log (how many times the client opened the quote before signing)
- IP and rough geolocation of the signer at the 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 collection as well as litigation before the commercial court.
