An audit career involves checking whether an organisation’s financial information is accurate and whether its controls and processes work as intended. External auditors, usually employed by accounting firms, examine clients’ financial statements and give an independent opinion on whether they present a true and fair view in line with accounting standards. Internal auditors work inside organisations, reviewing risks, controls, compliance and operations, and reporting to management and the audit committee. Most auditors start as associates or trainees at accounting firms, study for a professional qualification such as the CPA, ACA or ACCA, and progress through senior and manager levels toward partner, or move after a few years into corporate finance, internal audit, advisory or financial leadership roles. Audit is demanding during busy season but offers structured training, recognised qualifications and some of the strongest exit options in finance.
This guide is for students, graduates and career changers considering audit. It explains what external and internal auditors do, the skills and qualifications required, the career ladder, what busy season is really like and where audit can lead.
External audit vs internal audit
| External audit | Internal audit | |
|---|---|---|
| Employer | Accounting firms | The organisation being audited (or outsourced providers) |
| Main purpose | Independent opinion on financial statements | Assurance and advice on risks, controls and operations |
| Reports to | Shareholders, via the audit report; audit committee | Audit committee and senior management |
| Scope | Mainly financial reporting | Financial, operational, compliance, IT and strategic risks |
| Regulation | Heavily regulated, with independence rules | Guided by professional standards, such as those of the Institute of Internal Auditors |
| Typical qualification | CPA, ACA, ACCA | CIA, plus CPA or ACCA for many |
| Pace | Busy seasons around year-end reporting | More evenly spread, driven by the audit plan |
What external auditors do
External audit follows a broadly consistent cycle for each client:
- Planning: understanding the client’s business, risks and controls, setting materiality and designing the audit approach.
- Controls testing: checking whether key controls, such as approvals and reconciliations, work as designed.
- Substantive testing: testing balances and transactions directly, for example confirming bank balances, inspecting invoices, counting inventory and testing revenue recognition.
- Reviewing judgements: assessing management’s estimates, such as provisions, impairments and fair values.
- Completion: reviewing the financial statements and disclosures, evaluating misstatements, and forming the audit opinion.
- Reporting: issuing the audit report and communicating findings to the audit committee.
Junior auditors usually focus on testing and documentation, while seniors run fieldwork and managers and partners focus on judgement areas, client relationships and the overall opinion.
What internal auditors do
Internal auditors evaluate how well an organisation manages its risks. A typical internal audit might review the purchasing process, cybersecurity controls, compliance with regulations or the effectiveness of a new system. Internal auditors interview staff, review documents, test samples, identify weaknesses and recommend improvements, then follow up to check that actions are implemented.
Internal audit offers broader exposure to how a business works than external audit, often with more predictable hours. Many internal auditors start in external audit and move in-house after qualifying.
Skills auditors need
- Attention to detail: spotting inconsistencies and errors in large volumes of information.
- Professional scepticism: questioning evidence and explanations rather than accepting them at face value.
- Accounting knowledge: understanding financial statements and relevant accounting standards.
- Analytical skills: identifying unusual trends and risks, increasingly using data analytics tools.
- Communication: asking clear questions of client staff and explaining findings to managers and audit committees.
- Time management: working to tight deadlines across several clients.
- Teamwork: audits are delivered by teams that must coordinate closely.
- Integrity: auditors are trusted to be independent and objective.
Qualifications for an audit career
- CPA (U.S.): licensed CPAs are required for certain public accounting work, including signing audit opinions. Requirements include education, the Uniform CPA Examination and experience, set by each state.
- ACA (ICAEW), ACCA and ICAS (UK and internationally): chartered accounting qualifications commonly completed by auditors in training programmes at accounting firms.
- CIA (Certified Internal Auditor): the main global qualification for internal auditors, awarded by the Institute of Internal Auditors.
- CISA (Certified Information Systems Auditor): for IT auditors focusing on technology risks and controls.
Most large accounting firms sponsor qualifications for their graduate auditors, including exam fees and study leave. Check each body’s official requirements, as they change periodically. Our accountant salary guide shows how qualifications affect pay.
The audit career ladder
| Level | Typical experience | Main responsibilities |
|---|---|---|
| Associate / trainee | 0–2 years | Testing, documentation, studying for qualification |
| Senior associate / in-charge | 2–4 years | Running fieldwork, supervising juniors, client contact |
| Manager | 4–7 years | Managing engagements, budgets, reviewing work, client relationships |
| Senior manager / director | 7–10+ years | Overseeing portfolios of clients, complex judgements, business development |
| Partner | 10+ years | Signing audit opinions, leading client relationships, firm leadership |
Progression tends to be structured, with promotions often linked to qualification and performance reviews. Many auditors leave after qualifying or after reaching senior or manager level to take up roles in industry.
Pay
The U.S. Bureau of Labor Statistics reports a May 2025 median annual wage of $83,680 for accountants and auditors (BLS). Pay for auditors varies by firm size, location, qualification and level. Starting salaries at large firms are typically structured and rise with promotion and qualification. Partners at large firms earn considerably more, with profit shares. Moving into industry often brings a pay increase after qualification, especially into financial controller and finance manager roles.
What busy season is really like
Busy season is the period when many clients’ year-end audits must be completed, often in the months after a common financial year-end. During busy season, auditors may work long hours, including some evenings and weekends, to meet reporting deadlines. Outside busy season, hours are usually more moderate, with time for training, smaller engagements and study.
How auditors cope:
- planning study around busy season, since exam dates and busy periods can clash,
- protecting sleep and exercise where possible,
- communicating early with managers about workload and deadlines,
- using quieter periods to rest and catch up.
Firms increasingly use technology, offshore teams and better planning to reduce peaks, but busy season remains part of external audit life.
How technology is changing audit
Audit is being reshaped by data analytics and automation. Instead of testing small samples manually, auditors can now analyse entire populations of transactions to find unusual items, such as journal entries posted at odd times or payments to new suppliers. Automation tools handle routine tasks such as confirmations and document matching, and AI tools are starting to support document review and risk assessment.
For auditors, this means:
- learning data analytics tools and basic programming or scripting where useful,
- focusing more time on judgement, risk assessment and communication,
- understanding IT systems and controls, since most financial data flows through technology,
- staying alert to how clients use AI and automation, which creates new risks to audit.
Where audit leads: common exit opportunities
Audit is often described as a launchpad because it gives you deep accounting knowledge, exposure to many businesses and a respected qualification. Common next steps include:
| Exit | Why auditors fit |
|---|---|
| Financial reporting / technical accounting | Deep knowledge of accounting standards |
| Financial controller / finance manager | Understanding of controls, close processes and reporting |
| FP&A and commercial finance | Business understanding plus accounting foundation |
| Internal audit | Natural extension of audit skills, with broader scope |
| Transaction services / due diligence | Financial analysis of acquisition targets |
| Forensic accounting | Investigative and evidence-gathering skills |
| Risk and compliance | Controls knowledge and professional scepticism |
| Investment roles | Accounting depth valued in research and credit analysis |
| Finance director / CFO | Many finance leaders started in audit |
Many auditors move after qualifying, often within one to three years. Our financial analyst career guide explains one popular destination.
A day in the life (hypothetical)
Here’s an illustrative day for a second-year audit associate during fieldwork at a manufacturing client:
- 8:30 Team catch-up with the senior to agree today’s priorities: inventory testing and accruals.
- 9:00 Reviews inventory count results and reconciles them to the client’s records, noting differences to follow up.
- 11:00 Meets the client’s finance assistant to request missing invoices for sample testing.
- 13:00 Tests a sample of year-end accruals against supporting documents and later invoices.
- 15:00 Uses a data analytics tool to scan journal entries for unusual postings, flagging several for further review.
- 16:30 Documents work in the audit file, clearly explaining procedures and conclusions.
- 18:00 Updates the senior on findings and open requests before finishing for the day.
During busy season, a similar day might run later. Outside busy season, associates often spend time on training, smaller audits and exam study.
Common mistakes new auditors make
- Documenting poorly. In audit, work that isn’t documented clearly is treated as not done. Write workpapers so that a reviewer can follow every step without asking you.
- Accepting explanations too easily. Professional scepticism means corroborating what client staff say with evidence.
- Sitting on problems. If you find an issue or fall behind, tell your senior early; late surprises are far harder to fix.
- Losing sight of materiality. Spending hours on trivial differences while missing a significant risk area is a common early mistake.
- Neglecting exams. Combining audit work and study is hard, but falling behind on qualifications can slow promotion.
- Not asking why. Understanding the purpose of each test turns routine procedures into real learning and prepares you for senior roles.
How to stand out as a junior auditor
Strong associates build a reputation quickly by preparing before client meetings, keeping a list of open requests and chasing them politely, learning the firm’s audit software and analytics tools early, and reviewing their own work before submitting it. Seniors and managers notice associates who anticipate what’s needed, communicate clearly and treat client staff with respect. Those habits often matter as much as technical knowledge in performance reviews and promotion decisions.
They also volunteer for unfamiliar areas, such as IT controls or complex estimates, which broadens experience and makes them more valuable on future engagements.
Finally, they build good relationships with client finance teams, because cooperative clients make audits smoother and faster for everyone involved.
Small habits like these, repeated across every engagement, are what build a strong reputation within a firm.

FAQ
Is audit a good career for graduates?
Yes, for many graduates. It offers structured training, sponsored qualifications and broad business exposure that leads to many future roles.
What is the difference between an auditor and an accountant?
Accountants prepare and manage financial records and reports; auditors independently examine those records to check they’re accurate and comply with standards.
How long should I stay in audit?
Many people stay at least until they qualify, which often takes around three years. Some build long careers to partner level, while others move into industry roles.
Is internal audit less stressful than external audit?
Often, because work is spread more evenly across the year. However, internal audit has its own pressures around reporting to audit committees and managing difficult findings.
Takeaway
An audit career offers structured training, a respected qualification and exposure to many businesses, at the cost of demanding busy seasons. External audit focuses on independent opinions on financial statements, while internal audit covers risks and controls inside organisations. Whether you stay to partner or move into finance leadership, audit builds a strong foundation for many careers in finance.
