The letter, part by part
Daniel Fernandes (Audit Senior, ACA Qualified) is applying to be an Internal Auditor at Brindley Rail Services plc. Here is what each paragraph does.
- The hook
- The proof
- The fit
- The close
Dear Ms Kendall,
Moving from external to internal audit is a deliberate choice for me. I want to stay with one organisation long enough to see recommendations implemented, and Brindley Rail Services' investment in a risk-based audit plan across its depots suggests an audit function that is genuinely listened to. Your Internal Auditor vacancy is a strong match for my experience.
As an Audit Senior at a Birmingham accountancy firm, I lead fieldwork on manufacturing and transport clients with turnovers up to £250 million. Last year I ran 14 audits, managing teams of up to five, and delivered every file before the signing deadline. My review of one client's purchase-to-pay process uncovered £90,000 in duplicate supplier payments and led to stronger approval controls.
Your role calls for controls testing, data analytics and clear reporting to the audit committee. I use IDEA and Excel to test full populations rather than samples, document walkthroughs to a high standard, and write findings that are concise and actionable. As a qualified ACA with a solid grasp of the Three Lines model and the COSO framework, I can contribute from the start.
I would welcome the chance to discuss your audit plan and how my experience could support it. I am available for interview at short notice and can provide examples of anonymised audit reports and working papers. Thank you for considering my application, and I look forward to hearing from you.
Yours sincerely,
Daniel Fernandes
Skills to mention
Employers hiring a auditor often look for these. Name the ones you really have, with an example.
Phrases you can borrow
Change the details to your own, then copy them into your letter.
I write audit findings that managers can act on the same week they read them.
I test full populations wherever the data allows, because samples can hide the issues that matter.
I see a good audit as a partnership that leaves controls stronger, not just a report filed.
I plan fieldwork carefully so deadlines are met without cutting corners on evidence.
Tips for a auditor cover letter
- Quantify audits completed, team size, deadlines met and the value of issues you uncovered.
- Mention data analytics tools such as IDEA, ACL or Power BI, as full-population testing is increasingly expected.
- Reference frameworks like COSO or the Three Lines model when applying for internal audit.
- Show you can write clear, actionable findings, since reporting quality matters to audit committees.
- Never share confidential client names or details; describe sectors and sizes instead.
Mistakes to avoid
- Naming confidential clients or sharing sensitive audit details.
- Listing audit procedures without any findings or outcomes you achieved.
- Sounding adversarial about auditees rather than collaborative.
