Engagement letters, certificates, approval minutes, pay slips, social declarations, management mandates: digitize all signed documents from your firm and your clients with eIDAS proof level. Compliant with ordinance no. 45-2138, the OEC Code of Professional Conduct, the Commercial Code, the Labor Code (art. L3243-2) and eIDAS regulation.
All contractual documents of an accounting and payroll firm can be electronically signed, from the engagement letter to the individual social declaration.
Required under article 151 of the Code of Professional Conduct, the engagement letter must be signed by the customer BEFORE the service begins. Remote signature in 2 minutes, qualified timestamp that proves prior acceptance of conditions and fees.
Certificates for banks (turnover, borrowing capacity), social agencies (URSSAF), landlords or authorities. AES signature + audit trail = proof of authenticity that can be enforced.
Ordinary general meeting minutes (article L232-1 of the Commercial Code), with sequential or parallel signature of partners. Automatic maintenance of a dematerialized minutes register.
Compliant with article L3243-2 of the Labor Code (from the 2015 Macron law) and decree no. 2016-1762. Provision in a compliant digital safe, presumed employee consent — express refusal possible at any time.
Mandates by which the customer entrusts the firm with the management of social (DSN) and tax (VAT, IS, CFE) declarations. Advanced signature to identify the mandator and trace the precise scope of the mandate.
Confidentiality commitments, agreements for one-off services outside engagement letters, sub-contracting agreements between firms: the entire contractual scope of the firm is covered.
Six guarantees specifically tailored to the ethical and probative requirements of the chartered accountant profession.
OTP SMS + email verification of signer, qualified timestamp, SHA-256 fingerprint of document. The audit trail covers all requirements of the Code of Professional Conduct regarding formalization of commitments.
Each envelope produces a signature certificate: OTP identity, IP, qualified timestamp, SHA-256 hash, integrated in the signed PDF. Admissible before the Order Council, in fee disputes and before all courts.
TLS 1.3 encryption in transit, AES-256 at rest, strict data isolation per firm. 100% EU hosting (Germany), no sub-contracting outside the EU. Standard DPA included, compliant with professional secrecy under article 8 of ordinance 45-2138.
10-year archiving included at probative value (article L123-22 of the Commercial Code — retention period for accounting records). Full export at any time for transmission to a successor or for a tax audit.
Signature avancée conforme au règlement (UE) n°910/2014. Pour les actes exigeant le niveau qualifié (QES — actes authentiques), notre roadmap intègre un prestataire QTSP partenaire.
Public REST API, event webhooks, and ongoing integrations with major accounting production software (CEGID, ACD, RCA, ISACOMPTA, QuadraCompta). Compatible with your existing stack.
The probative value of electronic signature in an accounting firm rests on two fronts: demonstrating the customer's informed consent to the engagement letter (article 151 of the Code of Professional Conduct) and establishing the authenticity of certificates issued under article L823-12-1 of the Commercial Code.
Certyneo delivers for each signature an audit certificate integrated in the PDF, which groups technical evidence:
This bundle of evidence meets the requirements of article 1366 of the Civil Code (probative force of electronic writing) and is recognized by French case law (Cass. com., 13 March 2019). For certificates addressed to third parties (bank, URSSAF, landlord), the audit trail provides proof of authenticity of the document issued by the firm.
Certyneo operates within the legal and ethical framework applicable to the chartered accountant profession.
Article 151 of the Code of Professional Conduct mandates a written engagement letter prior to any service. Article 145 governs the confidentiality of customer data. Certyneo applies end-to-end encryption and probative-value archiving consistent with these obligations.
Article L123-12 sets accounting obligations for merchants; article L823-12-1 governs certificates issued by statutory auditors. Certyneo's advanced signature meets the authenticity and integrity requirements of these provisions.
Since the Macron law of 6 August 2015, the employer may provide the pay slip in electronic form under conditions guaranteeing its integrity, availability for 50 years (or until the employee reaches age 75) and data confidentiality.
Electronic writing has the same probative force as paper writing provided the signer's identity can be duly established and the document's integrity is guaranteed. Certyneo's advanced signature (AES) meets both requirements under regulation (EU) no. 910/2014.
Yes, without restriction. Article 151 of the Code of Ethics requires prior written documentation but does not prescribe any particular form. Certyneo's advanced signature (AES) meets the evidentiary requirement, with the advantage of precisely time-stamping the acceptance of fees and the scope of engagement BEFORE the service begins.
A certificate electronically signed with AES level (Certyneo) has the same value as a hand-signed and stamped paper certificate. The recipient (bank, URSSAF, landlord) can verify the audit trail from the verification URL included in the PDF certificate — they see the signatory's identity, the date, and the absence of document alteration.
Since the Macron law (January 1, 2017), the employer may provide the pay slip in electronic form without prior employee agreement, provided they have informed the employee at least one month in advance and comply with retention conditions (50 years or until the employee reaches 75 years old). The employee may object at any time.
Article L123-22 of the Commercial Code requires retention of accounting documents for 10 years. As a precaution, the same duration applies to engagement letters, which serve as proof of acceptance of fees in case of dispute. 10-year archiving is included in all Certyneo plans.
A public REST API is available with event webhooks (envelope.signed, recipient.signed, etc.). Native integrations with leading accounting software (CEGID, ACD, RCA, ISACOMPTA, QuadraCompta) are being rolled out. Contact us for the exact status on your solution.
