Engagement letters, retainers and sign-offs — governed from the start

Legatio locks scope, automates fee authorisations and closes engagements formally — so client relationships end as cleanly as they begin.

Built for
  • Managing Partners
  • Practice Managers
  • Client Onboarding Leads at accounting, tax advisory and consulting firms

Institutional challenges, answered directly.

Three things that go wrong on paper, and what replaces each of them.

Scope that was never locked

An engagement letter with loosely worded scope isn't a safeguard — it's an invitation. Work performed beyond what was written becomes work the firm did for nothing, discovered only when the invoice is questioned.

Legatio’s response

Retainer agreements are built with parameters the client cannot alter without triggering formal review — scope stays what it was agreed to be.

Fee authorisations left waiting

A retainer that sits unsigned doesn't just delay revenue recognition — it delays the engagement itself, while the client's need for the work hasn't gone anywhere.

Legatio’s response

Custom notification rules keep pending fee approvals, tax sign-offs and annual renewals moving without manual follow-up.

An exit with no record behind it

Offboarding a client without a formal, mutual, documented termination leaves the firm exposed the moment either party remembers the relationship differently than the other does.

Legatio’s response

Mutual engagement terminations are executed cleanly, with dual-party verification and a documented trail — an ending both parties can point to.

Legatio's dedicated engine for professional services.

01

Strict scope field-locking

Retainer agreements carry fixed parameters the client cannot alter. Any scope creep requires a formal, re-executed amendment, closing the door on informally agreed unpaid work.

02

Passive tracking and automated reminders

Custom notification rules keep pending fee approvals, tax sign-offs and annual renewals moving, removing manual follow-up by partners.

03

A dual-party exit protocol

Offboarding runs through a mutual termination request requiring dual-OTP verification, generating a documented trail both parties can point to.

04

Lawyer-drafted baselines

Legatio executes and locks terms built on templates drafted by practising Bombay High Court lawyers, structured to sit alongside requirements such as ICAI's SA 210.

The workflow, end to end.

Every executed document is kept for eight years from the date it was signed, at no extra charge and without you asking.

Professional Services questions

Ask us directly

No. Legatio executes and locks the terms your firm has already drafted and approved. It does not draft engagement scope or replace a partner's review.

Legatio structures execution to align with SA 210's requirement to agree engagement terms formally. The specific clause language should be confirmed with a practising CA or your firm's own compliance function before you rely on it.

Field-locking is designed to prevent exactly this gap. Any scope change requires a formal, re-executed amendment, closing the door on informally agreed changes that later become disputed.
