Cas d'usage Accountancy en United Kingdom

Engagement letters and fees

Engagement letters and fee agreements are form-free and signed via a link in minutes. The advanced signature (AES) records the client, scope and time, avoiding later disputes.

HMRC authorisations (64-8)

Authorisations to act for clients before HMRC are signed digitally and sent in bulk. The audit trail evidences the authority; the signed PDF can be filed in the client record.

Approval of annual accounts

Annual accounts and approval minutes are signed off by the client with a defined order and a lock until fully signed — avoiding delays at filing and Companies House deadlines.

Quel niveau de signature choisir ?

Le règlement eIDAS définit trois niveaux de signature électronique. Certyneo les couvre tous les trois et adapte l'authentification au niveau requis.

Pour les documents à faible enjeu (devis, bons de commande). Mise en place immédiate.

Avancée (AES)

Liée au signataire via OTP e-mail/SMS et audit trail. Standard recommandé pour la plupart des contrats.

Niveau recommandé pour ce secteur

Qualifiée (QES)

Équivalent juridique de la signature manuscrite, avec certificat qualifié. Pour les actes les plus sensibles.

Engagements are form-free — the advanced signature (AES) provides the necessary evidence. For records subject to retention, the QES offers the highest evidential weight.

Cadre légal British

Form-free engagements and record retention

Engagement contracts are form-free and can be concluded electronically. Accounting and tax records are subject to retention periods (typically six years under the Companies Act 2006 and HMRC rules); Certyneo archives signed documents with integrity and a timestamp.

Evidential weight (UK eIDAS)

Electronic signatures are admissible as evidence; the qualified signature (QES) carries the highest assurance. The audit trail of Certyneo (timestamp, IP, OTP) strengthens evidential weight in a dispute.
