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 ensures that the acceptance is attributable to an identified person and that the document has not been modified after signature.
Certyneo delivers for each signed quote or PO a audit certificate embedded in the PDF, which brings together all technical evidence:
- Signatory identity (verified email, phone number confirmed by OTP)
- Qualified time-stamp of acceptance — date enforceable against any late dispute
- SHA-256 hash of the quote as presented, which demonstrates the absence of later modification
- Consultation log (how many times the customer opened the quote before signing)
- IP and rough geolocation of the signatory at the time of acceptance
This body of evidence prevents common disputes ("the quote had been modified", "I never received this version", "the PO is not mine") and secures amicable recovery as well as litigation before the commercial court.
