E-Signatures for UK Accountants & Bookkeepers: Fast Client Engagement Letters

UK accounting practices lose days waiting for clients to print, sign, and scan engagement letters and annual accounts. Discover how ChickenSign enables sequential multi-party signing, 6-year audit trail retention, and instant client onboarding for £9.95/month.

Meeting Professional Standards (ICAEW & ACCA)

Quick Answer / Definition

Professional regulatory bodies including ICAEW, ACCA, and AAT mandate that accounting practices hold a valid, signed letter of engagement outlining terms of business, fee structures, and liability caps before commencing service.

Legacy signing platforms force accounting clients through confusing registration screens, leading to dropped onboarding and delayed fee collection.

Upload your own engagement letter (your terms, your wording) and send it for client signature and countersigning.

Furthermore, ChickenSign's verification portal at /verify/:code allows practice managers and compliance auditors to instantly verify cryptographic integrity without revealing client confidentiality.

Sequential Multi-Party Signing Workflow

Quick Answer / Definition

Sequential signing ensures the client signs the engagement terms first before the document is automatically passed to the firm's partner for final execution and cryptographic sealing.

When sending a partnership tax return approval or bespoke engagement package, select 'Sequential' in ChickenSign's visual stage.

Signer 1 (the client) receives their private signing link first via email, SMS, or WhatsApp. Once they authenticate their acceptance, Signer 2 (the partner) receives the countersignature notification.

When both complete, a dual SHA-256 sealed PDF is distributed to all parties.

Frequently Asked Questions

Does HMRC accept electronic signatures on client authorisations?

How long are completed documents stored?

In accordance with the Limitation Act 1980, ChickenSign retains cryptographic audit records for 6 years, ensuring full evidentiary protection during tax audits or client disputes.
