3What this role really is

An internal auditor checks specific areas of a business to make sure its financial controls work properly.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

You'll use Excel daily for data analysis, reconciliation, preparing workpapers, and creating basic schedules. This means VLOOKUPs, pivot tables, complex formulas, and ideally some familiarity with Power Query for data cleansing.

Workiva / AuditBoard (GRC & Audit Management) Intermediate

You'll use our GRC platform to document your audit workpapers, track findings, manage review notes, and upload evidence. You should be comfortable navigating the system and using its core functionalities.

SAP S/4HANA / Oracle NetSuite (ERP Systems) Intermediate

You'll need to navigate key modules (e.g., General Ledger, Accounts Payable) to retrieve transaction details, reports, and screenshots as evidence for your testing. Understanding read-only access is key.

Alteryx / IDEA / ACL (Data Analytics & CAATs) Basic

You'll typically run pre-built scripts or perform simple data extractions and reconciliations to support your audit testing. You should understand the basics of what these tools do and how to interpret their outputs.

Tableau / Power BI (Data Visualization) Basic

You'll mostly interpret dashboards and reports created by others to get a quick overview of performance or identify trends. Building your own simple visualisations might come later, but understanding them is a start.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Audit Testing Approach Follows prescribed test steps; escalates any deviation. Selects appropriate testing methods within defined scope; consults manager on novel approaches. Designs testing methodology for complex controls; approves changes to test plans.
Finding Severity Rating Documents observations; manager assigns severity. Proposes severity rating with supporting evidence; manager reviews and approves. Determines final severity rating for most findings; consults Director on material weaknesses.
Information Requests (PBCs) Sends standard PBC lists as provided. Tailors PBC lists to specific audit needs; follows up independently on outstanding items. Negotiates PBC requirements with senior management; resolves complex data access issues.
Audit Timeline Adjustments Escalates any potential delays immediately. Proposes minor adjustments to individual task timelines; consults manager on overall audit schedule impacts. Approves minor schedule changes for their audits; escalates significant delays to Director.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Workpaper Quality & Timeliness
The accuracy, completeness, and clarity of your audit workpapers, and whether they're submitted on time.
Target · <10% of workpapers returned for rework; 95% submitted by deadline.

You submit a workpaper for review, and it only needs minor formatting tweaks, no factual corrections or missing evidence. It's in on Thursday, exactly when we agreed.

Finding Accuracy & Substantiation
How well your identified control weaknesses are supported by evidence and how often they're accepted by management without significant challenge.
Target · >85% of drafted findings accepted by management without material changes.

You identify a control gap in expense reporting. Your finding clearly outlines the risk, the control failure, and is backed by three specific examples from transactions. Management agrees with your assessment.

Audit Section Completion Rate
The percentage of your assigned audit testing and documentation tasks completed within the agreed-upon timeframe.
Target · 95% of assigned testing completed by the agreed-upon deadline.

For the Q2 Accounts Payable audit, you were assigned 15 control tests. You completed 14 of them and clearly escalated the reason for the one outstanding item well in advance.

Issue Identification Beyond Scope
The number of relevant control weaknesses or process improvements you identify that weren't explicitly part of your initial testing plan.
Target · At least 1-2 value-add observations per significant audit.

While testing a specific control, you notice an inefficiency in the wider process that, if fixed, could save the team 5 hours a week. You raise this as a 'value-add observation' in the report.

Stakeholder Communication
How clearly and professionally you communicate with auditees and your internal team, especially when discussing findings or requesting information.
  • Auditees typically respond promptly and cooperatively to your requests. Your emails are clear, concise, and don't require multiple follow-ups for clarification. Your manager rarely needs to intervene in your communications with the business.
Application of Professional Skepticism
Your ability to question information, seek corroborating evidence, and not take things at face value, even when dealing with senior colleagues.
  • You consistently ask 'why' and 'how' questions during walkthroughs. You identify discrepancies in documentation or explanations and follow up until resolved. You challenge assumptions politely but firmly when evidence doesn't support them.
Adherence to IIA Standards
Your consistent application of the International Professional Practices Framework (IPPF) in your daily audit work.
  • Your workpapers clearly show evidence of planning, risk assessment, and proper documentation of testing. You consistently follow the Internal Audit methodology and ethical guidelines. Your manager notes your understanding of the 'Red Book' standards in reviews.
Proactive Problem Solving
Your initiative in identifying potential roadblocks in your audit work and proposing solutions before they become major issues.
  • You flag potential delays with PBC lists early and suggest alternative ways to get information. You research solutions to data extraction challenges rather than waiting for your manager to provide them. You come to your manager with a problem and at least one idea for how to fix it.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Making a Tangible Difference

You'll feel satisfied when you uncover a control weakness that genuinely improves our financial processes or prevents future losses. Seeing your recommendations implemented and making things better is a real win.

You spot a gap in our payment approval process that could lead to duplicate payments. Your finding leads to a new control being put in place, saving the company money and giving you a real sense of accomplishment.

Solving Puzzles & Investigating

If you enjoy piecing together information, following trails of evidence, and figuring out why something isn't working as it should, you'll love the investigative nature of audit work. It's like being a financial detective.

You're given a general ledger account to review for unusual activity. You dig into the transactions, talk to the relevant teams, and uncover a process breakdown that explains the anomalies. It's a proper 'aha!' moment.

Continuous Learning & Development

Every audit is a chance to learn about a new part of the business, a new system, or a new regulatory requirement. You'll constantly be expanding your knowledge of finance, risk, and controls.

One quarter you're auditing treasury operations, the next it's IT general controls. You're always picking up new skills and understanding how different functions contribute to the overall business.

What frustrates people
  • The 'PBC Black Hole': You send a clear list of documents, and what you get back is incomplete, late, or completely irrelevant, forcing you to chase endlessly.
  • The 'Groundhog Day' Audit: Finding the same control weakness you flagged two years ago because the 'fix' was never properly implemented or monitored.
  • Being seen as the 'police': Some business teams might view you as a hindrance rather than a partner, making it harder to get the information you need.
  • The 'urgent' request that gets deprioritised: You'll be asked to drop everything for an 'urgent' review, only for the business to lose interest once you've started.
What this role does not give you
  • Immediate, direct authority to implement change (you influence, you don't dictate).
  • A purely strategic, high-level view (you'll be in the weeds, deep in transactions and controls).
  • A quiet, predictable routine (expect shifting priorities and unexpected issues to investigate).
  • A role where you only deal with 'clean' data (you'll spend a lot of time cleaning and reconciling).

8Who you work with

This role directly underpins the reliability of our financial reporting and operational controls. Your work helps us identify and fix weaknesses before they become big problems, protecting our reputation, reducing financial risk, and ensuring we meet all our regulatory obligations. You're essentially a safeguard, helping to keep the business honest and secure.

Inside the business
  • Finance Operations teams (Accounts Payable, Accounts Receivable, General Ledger)
  • Risk Management Department
  • IT Security and Operations
  • Compliance Officers
  • Treasury Team
Outside the business
  • External Auditors (for coordination and information sharing)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • A minimum of 2 years of experience in internal audit, external audit, or a relevant financial controls role.
  • Demonstrable experience in performing control testing and documenting audit findings.
  • A solid understanding of financial processes and internal control concepts.
  • Proven ability to work independently on assigned tasks and manage your own workload effectively.
  • Strong analytical skills with a keen eye for detail and the ability to spot inconsistencies.

10What to practise next

Where the job is going, and what to do about it starting this week.

Continuous Controls Monitoring (CCM) Design

The future of audit isn't just periodic reviews; it's real-time assurance. You'll need to understand how to help design and implement automated monitoring systems that flag control breaches as they happen, shifting your role to investigating exceptions.

Rule-Based Monitoring · Data Integration for CCM · Exception Management Workflows

  • This week: Research common CCM tools and their capabilities (e.g., within Workiva or ServiceNow GRC).
  • This month: Discuss with your manager how a specific manual control you're testing could potentially be automated for continuous monitoring.
  • Month 2: Map out the data flows required for a simple CCM scenario in one of our financial processes.
  • Month 3: Look for case studies or webinars on successful CCM implementations in finance organisations.

Quick win: Identify one manual control in your current audit that generates a lot of data. Think about how you'd design an automated check for it, even if just conceptually.

Cybersecurity & IT General Controls (ITGC) Acumen

Financial risks are increasingly linked to cyber risks. You'll need a stronger grasp of IT general controls, data security, and common cyber threats to effectively audit financial systems and data integrity.

Access Controls & Segregation of Duties · Change Management Controls · Data Backup & Recovery

  • This week: Read up on the basics of ITGCs and their relevance to financial reporting.
  • This month: Shadow an IT Auditor (if we have one) or collaborate closely on an audit with IT components.
  • Month 2: Take an introductory online course on cybersecurity fundamentals (e.g., from Cybrary or Coursera).
  • Month 3: Review our organisation's IT policies related to access management and change control, and consider how you'd test them.

Quick win: When auditing a financial process, always ask about the underlying IT system's access controls and how changes are managed. Start building that 'IT lens'.

11Staying current once you are in

What people here do to keep up
  • Regularly attend webinars and workshops offered by the IIA or other professional bodies on emerging audit trends, regulatory changes, or new technologies.
  • Engage in peer-to-peer learning within the team, sharing insights from different audit engagements or challenging areas.
  • Seek out opportunities to learn new data analytics tools or techniques, even if it's just through online tutorials.
  • Participate in cross-functional projects or initiatives that give you exposure to different parts of the business and their control environments.

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Prompt Engineering & LLM Integration

AI is already changing how we research, summarise, and draft. Auditors who can effectively 'talk' to Large Language Models (LLMs) will significantly boost their productivity, allowing them to focus on critical thinking rather than manual drafting. Competitors are already using this to draft reports in minutes.

  • Effective Prompting Techniques
  • Context Windows & Token Limits
  • Output Validation & Hallucination Detection
  • Ethical AI Use in Audit

Advanced Data Visualisation for Findings

Presenting audit findings clearly and impactfully is crucial. Static tables are out; dynamic, interactive dashboards that tell a story are in. Being able to visualise data helps management quickly grasp complex issues and drives faster remediation.

  • Choosing the Right Chart Type
  • Dashboard Design Principles
  • Storytelling with Data
  • Interactivity & Drill-Downs

The ten Future Fluencies

Zavmo analysis

The credential is what you can do today. These are what keep you valuable.

A qualification proves you can do the job as it's defined today. These ten are what decide whether you're still the obvious person for it in five years. They're the capabilities employers are now writing into senior roles faster than people are learning them. Zavmo weaves them through whatever you study, so you come out with both: the credential and the fluency.

The highlighted ones are the Fluencies your role leans on hardest, from how Internal Auditor is actually changing.

The career path, and where it branches

Internal Auditor is a start, not a ceiling. Each step below asks for new skills and hands back more autonomy.

  1. You'll move from executing assigned sections to leading smaller audit engagements end-to-end, acting as the 'Auditor-in-Charge'. This means more responsibility for planning, managing junior staff (if any), and drafting the full audit report.

    • End-to-End Audit Planning Developing comprehensive audit programmes based on risk assessments.
    • Complex Finding Articulation Drafting nuanced findings and recommendations for broader business impact.
    • Quality Assurance Review Reviewing workpapers of junior staff for quality and adherence to standards.
Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of audit work can be repetitive. Imagine having a smart assistant that handles the grunt work, freeing you up to focus on the truly interesting bits – like deep analysis and finding those critical insights. That's exactly what AI can do for you in this role.

We're not talking about replacing auditors; we're talking about making you a more efficient, impactful auditor. AI tools are already here, and they're transforming how we approach everything from data analysis to report writing. You'll be using these tools to automate the mundane, so you can spend more time on what actually matters: professional judgement and strategic thinking.

Automated Report & Workpaper Drafting

Use AI to generate first drafts of audit findings, executive summaries, and workpaper narratives based on your structured data inputs and test results. You'll spend less time writing from scratch and more time refining the message and ensuring accuracy.

Regulatory & Policy Synthesis

Feed new regulations (like updates from the FCA or PRA) or complex internal policies into AI tools. They'll summarise key requirements and highlight potential impacts on existing controls, saving you hours of manual research and helping you identify audit risks faster.

Anomaly & Fraud Detection

Instead of manually sampling, use AI to scan vast datasets from our GL, T&E, or vendor master files. The AI will flag unusual patterns, outliers, or potential red flags that human auditors might miss, directing your investigative efforts to the highest-risk transactions.

Data Extraction & Reconciliation

Got messy data from different systems? AI-powered tools can help you extract, cleanse, and reconcile large datasets much faster than manual methods. This means less time on data prep and more time on actual analysis and testing, making your life a lot easier.
