Contract and Document Management for CA and CS Firms: Engagement Letters, Client Documents and Deadline Tracking
Chartered accountant and company secretary practices run on engagement letters, consent letters, client KYC and hundreds of dated filings. A practical guide to managing the paper: what the engagement letter must cover, executing client documents electronically, and tracking obligations across a client base.
A mid-sized chartered accountancy or company secretarial practice signs more documents in a month than most of its clients do in a year: engagement letters, consent letters, representation letters, board resolutions, DSC-based filings, and client contracts it reviews. The firm's own contracting is usually the least managed part of the practice. This guide sets out a workable system: what the engagement letter should contain, how to execute client-facing documents electronically, and how to track the obligations and deadlines that run across a client base. Position as of October 2026.
The engagement letter
The engagement letter is the firm's contract. Its essentials:
- Scope: the services, what is excluded, and the client's responsibilities (records, information, timelines).
- Fees, GST and TDS: fees exclusive of GST; the client deducts TDS under section 194J of the Income-tax Act, 1961 (professional services, 10%; threshold Rs 50,000 a year from 1 April 2025) and issues the certificate.
- Payment terms: if the firm is a registered micro or small enterprise, the agreed period cannot exceed 45 days from acceptance under section 15 of the MSMED Act, 2006, and the client's deduction depends on timely payment (section 43B(h)).
- Confidentiality and data: the firm processes client personal data (employees, directors, KYC documents); under the DPDP Act, 2023 the firm may be a Data Processor for the client in some flows and a Data Fiduciary in others; say which, and include processing terms (section 8(2), from 13 May 2027).
- Limitation of liability: a cap, typically a multiple of fees, with carve-outs the professional rules require.
- Term, termination and document retention: how long the firm keeps working papers and client records, and what is returned on exit.
- Professional standards: reference to the applicable ICAI or ICSI requirements for engagement letters. ****
Executing client documents electronically
Most documents the firm and its clients exchange can be e-signed: engagement letters, consent letters, representation letters, board resolutions (subject to the company's articles and the Companies Act's requirements for the particular resolution), and declarations. Statutory filings with the MCA, income-tax and GST portals require the client's or the professional's DSC under the portal rules (rule 8 of the Companies (Registration Offices and Fees) Rules, 2014 requires e-forms to be authenticated with a digital signature). A practical split:
- DSC for partners and for statutory filings.
- Aadhaar eSign for clients' directors and proprietors signing engagement and consent letters.
- Audit trail retained for every document; electronic records are proved under section 63 of the Bharatiya Sakshya Adhiniyam, 2023.
Keep the firm's DSC tokens with the named holders; section 66C of the IT Act, 2000 makes fraudulent use of another's electronic signature an offence.
Tracking obligations across a client base
The firm's calendar is a contract register in disguise. For each client, the register should hold:
- Engagement term and renewal; fee revision date.
- Statutory deadlines for the services engaged (annual filings, returns, event-based filings), with owner and status.
- Client-side obligations (information due dates) so delays are documented.
- Document retention and return dates.
- MSE payment deadlines on the firm's own invoices.
Reports to run monthly: engagements expiring in 90 days; filings due in 30 days without client inputs; invoices past 45 days where the firm is an MSE; clients whose engagement letter predates the current template.
Reviewing clients' contracts
Many CA and CS firms review clients' vendor, lease and shareholder agreements. A consistent checklist (stamping, execution method, MSE payment terms, GST clauses, DPDP processor terms, auto-renewal windows) applied through a template produces a more reliable review than ad hoc reading, and a record of what was reviewed.
Where Legatio fits. Legatio gives a practice its engagement-letter templates, electronic execution with DSC and Aadhaar eSign, a per-client document record with audit trails, and a register of engagement, filing and payment dates with alerts to the responsible partner. Professional standards and portal rules are the institutes' and regulators'.
