Scope creep usually starts as one extra entity, one more report pack, or one more round of confirmations, then the filing date gets tight and nobody agrees on what changed. This audit engagement letter gives the statutory audit appointment a place to pin down what’s in scope, what counts as a change, and what happens when timing moves.

The letter starts by tying the appointment back to the accepted proposal and the point the terms apply from, then the Scope section says the work matches what was sold and gets confirmed in writing before fieldwork begins. Payment splits the fee into two stages, sets 14-day terms, and explains what happens if work pauses for overdue invoices, while Limits of responsibility makes it clear where delays come from when information or third-party confirmations land late... and how dates get updated and agreed.

  • It covers the statutory audit appointment Ties the engagement back to the accepted proposal, states when the terms apply, and confirms independence and acceptance checks before work starts.
  • Scope Defines the audit period and entities, confirms the reporting framework in writing, and treats anything outside that confirmation as a change that needs approval.
  • Payment Prices the fee in two stages, sets 14-day invoice terms, and explains how pausing for non-payment shifts timelines once a revised plan is agreed in writing.
  • Confidentiality Keeps non-public information private, limits sharing to people involved in the audit or required requests, and states what each side keeps when the engagement ends.
  • Ending the engagement Explains how either side can end the engagement, how the notice period gets agreed in writing, and how completed work and unavoidable costs get settled.

It takes a near-neutral blue-grey page with security-tape green for the accept action, with Raleway headings over Inter body text so the clauses read like a letter instead of a brochure. After you add your names, dates, and any terms you handle differently, you send the letter and the client signs online, leaving both sides with the same signed engagement to work from.

We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

What to include in an audit engagement letter

PartWhat it covers

It covers the statutory audit appointment

Connects the appointment back to the accepted proposal, states when the terms apply, and confirms independence and engagement acceptance checks before work begins.

Scope

Defines the audit as a project for the period and entities you confirm, and says any extra entities, reporting packages, or requirement changes get handled as a written, approved change with fee and timing impact.

Payment

Splits the audit fee into two stages, sets 14-day invoice terms, and explains what happens if work pauses for overdue invoices and timelines need a revised written plan.

Confidentiality

States what information stays private on both sides, when sharing is allowed for running the audit or required requests, and what each side keeps at the end of the engagement.

How we’re engaged

Clarifies the firm’s independence and who runs acceptance, scope confirmation, and day-to-day coordination, while keeping the client responsible for records, financial statements, and formal appointment steps.

Limits of responsibility

Sets the standard of care and the limits of what an audit is designed to detect, and allocates responsibility for delays caused by late information or slow third-party confirmations.

Ending the engagement

Explains termination by notice, how the notice period is agreed in writing, and how fees and credits get calculated to the end date, with a Signature to sign off the engagement.

Who it is for

Audit partners and managers in audit & assurance who need a signed engagement letter before fieldwork starts and confirmations, PBC lists, and filing dates begin to move.

The contract in full

It covers the statutory audit appointment as described in the proposal you accepted, and it applies from the date you sign and return it.

We will only act once our independence and engagement acceptance checks have cleared and the formal appointment is in place. If anything in the proposal and this letter conflict, we will talk it through with you and confirm the agreed position in writing before we proceed.

Scope

This engagement covers the statutory audit appointment on a project basis, for the period and entity or entities we confirm during the scope and reporting framework walk-through.

What you get under this engagement is exactly the work listed in the proposal under “What we sell”. We will confirm, in writing, the audit scope and the reporting framework before fieldwork starts. Anything outside what we confirm, including additional entities, late-added components, extra reporting packages, or a change in reporting requirements, is treated as a change. If something changes mid-audit, we will set out the extra work, the fee impact, and any timing impact, and we will only proceed once you approve the variation in writing.

Payment

Our fee for the statutory audit appointment is paid in two stages. You pay 50% when you sign to book the work. You pay the remaining 50% when the engagement is complete.

We will invoice at those points. Each invoice is payable within 14 days of its invoice date.

If an invoice goes past due, we will tell you what is outstanding and ask when payment will be made. If payment is still not received, we may pause work until the account is brought up to date. If we pause, timelines move by the length of the pause, and any knock-on effects on third-party confirmations and filing dates sit with the revised plan we agree with you in writing.

Confidentiality

Both sides will keep each other’s non-public information private. For you, that includes financial information, systems access, and anything we learn about your customers, suppliers, pricing, and contracts. For us, it includes our templates, checklists, and the way we plan and perform our audit work.

We will only share your information with people who need it to run the audit, such as component auditors or specialists, and only to the extent required. We may also need to respond to regulator or professional requests where we are required to do so.

When the engagement ends, you can keep and use the signed appointment and onboarding pack once fees are paid in full. We keep our working papers and do not release them to third parties unless we agree this with you in writing or we are required to do so.

How we’re engaged

We are engaged as an independent professional firm. We are not your employee, officer, or agent, and we do not make management decisions for you.

We are responsible for our own people, taxes, tools, and the way we organise our work. For this engagement, Eileen Tan is the audit engagement partner responsible for acceptance, independence sign-off, and the final scope and reporting framework confirmation. Marcus Lim runs the day-to-day planning, information requests, and coordination, including group or component instructions.

You are responsible for your records, the financial statements, and for arranging the formal appointment and authorised signatories. If board or shareholder approvals are required, we will wait for those approvals before issuing the onboarding pack.

Limits of responsibility

We will carry out our work with reasonable skill and care, using the information you provide and the responses we receive from third parties. You understand that an audit is not designed to catch every error or every instance of fraud, especially where information is withheld, altered, or misrepresented.

We are not responsible for delays or missed target dates caused by late information, slow responses to questions, or slow third-party confirmations from banks, customers, suppliers, or component teams. If these delays occur, we will update dates promptly and agree a revised plan with you.

We are also not responsible for work that falls outside the audit scope and reporting framework we confirm in writing, unless you approve a written variation before we do that additional work.

Ending the engagement

Either of us can end this engagement by giving notice. Because notice needs to fit your reporting timetable, we will agree the notice period with you in writing if termination comes up.

If you end the engagement, you will pay for the work we have completed up to the end date, plus any unavoidable costs we have already committed with your knowledge. If we have already invoiced more than the value of work completed, we will credit the difference. If we have invoiced less, we will invoice the balance. All invoices remain payable within 14 days of the invoice date.

If we end the engagement because our independence or acceptance position changes, we will explain the issue to you. On termination, we will hand over the signed appointment and onboarding pack materials that have been paid for. Our templates and working papers remain ours.

Questions about this contract template

What should an audit engagement letter include?

An audit engagement letter usually covers the audit appointment, the confirmed scope and reporting framework, fees and payment terms, confidentiality, responsibility limits, and how termination and final billing work. The letter also needs clear wording on how changes mid-audit get approved and priced.

How do you prevent scope creep in a statutory audit?

Scope control comes from confirming the entities, period, and reporting framework in writing before fieldwork begins, then treating anything outside that confirmation as a variation. The letter should say the extra work, fee impact, and timing impact get agreed before the team proceeds.

What payment terms are common for audit engagements?

Many audit engagements split payment into stages tied to booking and completion, with a defined due period for each invoice. This letter uses two stages and 14-day invoice terms, and it explains when work may pause for non-payment and how timelines get revised in writing.

Who is responsible for delays during an audit?

The auditor can plan and follow up, but delays often come from late client information, slow responses to questions, or slow third-party confirmations from banks, customers, suppliers, or component teams. The letter should say dates get updated promptly and a revised plan gets agreed when delays happen.

Can an audit engagement be terminated partway through?

An audit engagement can be ended by notice, but the notice period needs to fit the reporting timetable and should be agreed in writing if termination comes up. The letter should also say how fees are settled for work completed and any unavoidable costs already committed.

What confidentiality terms should be in an audit engagement letter?

Confidentiality terms normally cover client financial information and access, and also the auditor’s templates and working methods. The letter should also state when sharing is allowed, such as involving component auditors or responding to required professional or regulatory requests.
