Audit Engagement and SA 210 — Terms of Audit Engagements

## Audit Engagement and SA 210

### What is an Engagement?

An engagement is a formal arrangement between two parties to do something. In audit, it is the formal agreement between the client and the auditor under which the auditor agrees to provide audit services.

> Analogy: Just as a marriage engagement leads to an invitation card, an audit engagement leads to an Engagement Letter.

### The Engagement Process under SA 210

SA 210 governs how the auditor and client agree to the terms of an audit engagement. The five-step process:

StepActionWho Acts
1InquiryClient approaches the auditor
2ProposalAuditor submits a proposal to the client
3Terms of EngagementBoth parties negotiate and agree on scope, fees, responsibilities
4Letter of EngagementAuditor sends formal document confirming agreed terms
5Letter of AppointmentClient formally appoints the auditor

### Why the Engagement Letter Matters

  • Defines the scope of the audit
  • Sets expectations for both parties
  • Reduces risk of misunderstandings about responsibilities
  • Provides legal protection to the auditor

Worked example

### Example 1

X Ltd. invites ABC & Co. (auditors) for their annual audit. ABC & Co. sends a proposal outlining fees and scope. After discussion, both agree on terms. ABC & Co. sends a Letter of Engagement confirming those terms. X Ltd. then issues a Letter of Appointment. The audit can now commence under SA 210.

⚠️ Common exam mistakes

  • Confusing the Letter of Engagement (sent by the auditor to the client) with the Letter of Appointment (sent by the client to the auditor)
  • Thinking the engagement letter is optional — SA 210 requires it to confirm the agreed terms before the audit begins
  • Getting the sequence wrong — the correct order is: Inquiry → Proposal → Terms → Letter of Engagement → Letter of Appointment
Reference: SA 210 — Agreeing to the Terms of Audit Engagements — SA 210
