Engagement letters, certificates, minutes of approval, payslips, social declarations, management mandates: dematerialize all documents signed by your firm and your clients with an eIDAS level of proof. Compliant with ordinance no. 45-2138, the OEC Code of Ethics, the Commercial Code, the Labor Code (art. L3243-2) and the eIDAS regulation.
All contractual documents of an accounting and payroll firm can be electronically signed, from the engagement letter to the individual social declaration.
Mandatory under article 151 of the Code of Ethics, the engagement letter must be signed by the client BEFORE the service begins. Remote signature in 2 minutes, qualified timestamp that proves prior acceptance of terms and fees.
Certificates for banks (turnover, debt capacity), social organizations (URSSAF), landlords or authorities. AES signature + audit trail = proof of authenticity that can be enforced.
Minutes of ordinary general meetings (article L232-1 of the Commercial Code), with sequential or parallel signature of partners. Automatic maintenance of the dematerialized register of minutes.
Compliant with article L3243-2 of the Labor Code (from the 2015 Macron law) and decree no. 2016-1762. Made available in a compliant digital safe, presumed consent of the employee — express refusal possible at any time.
Mandates by which the client entrusts the firm with the management of social (DSN) and tax (VAT, corporate income tax, CFE) declarations. Advanced signature to identify the principal and trace the precise scope of the mandate.
Confidentiality commitments, one-off service agreements outside the engagement letter, subcontracting agreements between firms: your entire contractual scope is covered.
Six guarantees specifically tailored to the ethical and probative requirements of the chartered accountancy profession.
OTP SMS + email verification of the signer, qualified timestamp, SHA-256 fingerprint of the document. The audit trail covers all Code of Ethics requirements regarding formalization of commitments.
Each envelope produces a signature certificate: OTP identity, IP, qualified timestamp, SHA-256 hash, embedded in the signed PDF. Admissible before the Professional Board, in fee disputes and before all courts.
TLS 1.3 encryption in transit, AES-256 at rest, strict data isolation by firm. 100% EU hosting (Germany), no subcontracting outside the EU. Standard DPA included, compliant with professional confidentiality of article 8 of ordinance 45-2138.

Public REST API, event webhooks, and ongoing integrations with leading accounting software (CEGID, ACD, RCA, ISACOMPTA, QuadraCompta). Compatible with your existing stack.
The probative value of an electronic signature in an accounting firm comes down to two fronts: demonstrating the client''s informed consent to the engagement letter (article 151 of the Code of Ethics) and establishing the authenticity of certificates issued under article L823-12-1 of the Commercial Code.
Certyneo delivers for each signature a audit certificate embedded in the PDF, which groups together technical evidence:
This body 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., March 13, 2019). For attestations addressed to a third party (bank, URSSAF, landlord), the audit trail provides proof of authenticity of the document issued by the firm.
Certyneo complies with the legal and ethical framework applicable to the accountancy profession.
Article 151 of the Code of Ethics requires a written engagement letter prior to any service. Article 145 governs the confidentiality of client data. Certyneo applies end-to-end encryption and archiving with probative value compatible with these obligations.
Article L123-12 sets out the accounting obligations of merchants; Article L823-12-1 governs attestations issued by statutory auditors. Certyneo''s advanced signature meets the authenticity and integrity requirements of these provisions.
Since the Macron Act of August 6, 2015, employers may deliver the payslip 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 that the identity of the signer can be duly established and the integrity of the document 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 writing but prescribes no particular form. Certyneo''s advanced signature (AES) meets the probative requirement, with the advantage of precisely timestamping acceptance of fees and the scope of the engagement BEFORE the service begins.
An attestation signed electronically at AES level (Certyneo) has identical value to a paper attestation signed by hand and stamped. The recipient (bank, URSSAF, landlord) can verify the audit trail from the verification URL included in the PDF certificate — they see the signer''s identity, the date, and absence of document alteration.
Since the Macron Act (January 1, 2017), employers may deliver the payslip electronically without prior employee consent, provided they have informed the employee at least one month in advance and comply with retention conditions (50 years or until the employee reaches age 75). 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 period applies to engagement letters, which serve as proof of fee acceptance 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.
