A request from your auditor can feel urgent when financial statements, tax schedules, board papers, and an AGM deadline are already competing for attention. Knowing what happens during an external audit helps directors and finance teams prepare the right records early, answer questions efficiently, and avoid preventable delays.

An external audit is an independent examination of an organization’s financial statements and selected underlying records. Its purpose is to enable the auditor to express an opinion on whether the financial statements are prepared, in all material respects, according to the applicable financial reporting framework. For Singapore companies, this commonly includes the relevant financial reporting standards and statutory requirements.

The process is structured, but it should not be disruptive when the audit is planned well. The precise procedures depend on the size of the entity, its operations, its risk profile, and the quality of its accounting records.

What Happens During an External Audit?

An external audit generally moves through planning, risk assessment, evidence gathering, review, and reporting. Although these stages can overlap, each has a clear purpose: the auditor needs sufficient appropriate evidence before signing an audit report.

The audit team remains independent from management. Management prepares the financial statements and is responsible for the accuracy of its records, internal controls, and disclosures. The auditor tests and evaluates the information provided. This distinction matters because an audit does not transfer financial reporting responsibility from directors or management to the audit firm.

Planning starts with understanding the business

Before detailed testing begins, the auditor seeks to understand the organization and its environment. This includes its business activities, ownership structure, accounting policies, revenue sources, major expenses, financing arrangements, related-party transactions, and significant changes during the year.

For an SME, planning may focus on sales processes, inventory, cash controls, payroll, and director transactions. For a charity or nonprofit, the focus may also include restricted funds, donations, grants, and fund utilization. For an MCST, maintenance fund collections, sinking fund balances, contractor costs, and managing agent records may require particular attention. A group audit may involve component reporting packages and consolidation adjustments.

The auditor will usually issue a request list and agree on a timetable with the client. A practical timetable identifies when the draft financial statements will be ready, when supporting schedules can be provided, who will answer audit queries, and when the board or AGM needs the final report. Early coordination is often the simplest way to protect a reporting deadline.

Risk assessment determines where testing is needed

Auditors do not verify every transaction. They assess where material misstatements are more likely to arise, then design procedures that address those areas. A material misstatement is one that could reasonably influence the decisions of users of the financial statements.

Revenue recognition, inventory valuation, receivables collectibility, management estimates, related-party balances, and manual journal entries are common areas of focus. The auditor also considers fraud risk. This does not mean the auditor assumes wrongdoing has occurred. It means the audit must be designed with professional skepticism, particularly where transactions or estimates could be manipulated.

During this stage, the auditor may ask how approvals are obtained, who can process payments, whether bank reconciliations are reviewed, and how changes to accounting records are controlled. Effective internal controls can reduce the need for certain detailed tests. Weak or undocumented controls may lead to more substantive testing and more supporting documents being requested.

Audit Fieldwork: Documents, Testing, and Questions

Fieldwork is the stage most clients associate with an audit. The team examines records and performs tests to obtain evidence supporting the amounts and disclosures in the financial statements.

Typical records requested may include:

• Trial balance, general ledger, and draft financial statements
• Bank statements, bank reconciliations, and confirmations
• Sales invoices, contracts, customer receipts, and receivables aging reports
• Supplier invoices, payment records, expense schedules, and creditor listings
• Payroll reports, tax records, fixed asset registers, and lease agreements
• Board minutes, key contracts, loan agreements, and related-party information

The auditor selects samples based on risk, value, and the nature of the population. For example, a sample of sales may be traced from the ledger to invoices, delivery documents, and customer receipts. Expense transactions may be checked against supplier invoices, approvals, and payment evidence. Bank balances may be independently confirmed with the bank, while trade receivable balances may be confirmed directly with selected customers.

Some evidence comes from observation. Where inventory is material, the auditor may attend a physical stock count and perform test counts. The auditor is not responsible for conducting management’s count, but observes the process and checks whether the final inventory records are reliable.

Questions during fieldwork are not automatically signs of a problem. They are part of the evidence-gathering process. A prompt, complete response usually keeps the audit moving. If a document is unavailable, explain why and provide alternative evidence where possible rather than leaving the request unanswered.

The auditor evaluates estimates and unusual transactions

Not every financial statement figure comes directly from an invoice or bank statement. Management may need to estimate expected credit losses, inventory obsolescence, useful lives of assets, impairment, provisions, or the fair value of certain instruments.

The auditor evaluates whether these estimates are reasonable based on available evidence and whether the related disclosures are adequate. This can involve comparing prior-year estimates with actual outcomes, reviewing assumptions, or considering market and operational conditions at year-end.

Unusual transactions often receive additional attention. Examples include large year-end sales, significant payments to related parties, new loans, restructuring costs, or transactions entered into shortly before the reporting date. These items are not necessarily incorrect, but they may carry higher accounting or disclosure risk.

Differences and control issues are discussed

Testing may identify errors, missing disclosures, classification issues, or differences between accounting records and supporting evidence. The audit team will discuss these matters with management and request proposed adjustments where appropriate.

Some differences may be minor individually but important in total. Others may relate to disclosure rather than the amount recorded. Management decides whether to adjust the financial statements, but uncorrected differences must still be evaluated by the auditor when forming the audit opinion.

The auditor may also communicate internal control deficiencies to management or those charged with governance. This is intended to help the organization strengthen its processes. It is not a substitute for management’s own responsibility to maintain adequate controls.

Final Review, Management Representation, and the Audit Report

Once fieldwork is substantially complete, the auditor performs final procedures. These commonly include reviewing events after the reporting date, assessing whether the organization can continue operating as a going concern, checking the overall presentation of the financial statements, and considering whether the evidence obtained supports the planned opinion.

Management is normally asked to provide a written representation letter. This confirms certain matters discussed during the audit, such as management’s responsibility for the financial statements, the completeness of information provided, and disclosures relating to related parties, subsequent events, or potential litigation. A representation letter supports audit evidence, but it does not replace underlying documents and records.

The final audit report is then issued with the financial statements. An unmodified opinion is commonly described as a clean opinion. It means the auditor concludes that the financial statements present fairly, in all material respects, under the applicable framework. It does not mean the business is financially strong, free from all errors, or guaranteed to be fraud-free.

Where necessary, the report may contain a qualified opinion, adverse opinion, or disclaimer of opinion. These outcomes are less common and arise when there is a material issue with the financial statements or when the auditor cannot obtain sufficient appropriate evidence. Clear communication early in the process gives management the best chance to resolve issues before report finalization.

How to Keep the Audit Efficient

An efficient audit is usually the result of preparation, not shortcuts. Reconcile bank accounts and key control accounts before submitting the trial balance. Ensure the fixed asset register, receivables aging, payables listing, and inventory records agree with the ledger. Prepare supporting schedules that explain significant movements from the prior year.

It also helps to appoint one internal coordinator who can track requests, gather documents, and involve the right people when questions require operational input. Finance staff should not feel they need to guess at an answer. Accurate, timely explanations are more useful than quick but incomplete responses.

A qualified audit team should apply the same professional standards whether the entity is a growing business, charity, MCST, or group company, while keeping requests proportionate to its circumstances. Koh & Lim Audit PAC focuses on clear coordination, responsive communication, and timely audit completion so clients can meet their reporting and AGM obligations with less operational stress.

Treat the audit as a practical annual check on the quality of your financial reporting. With organized records, early communication, and a realistic timetable, it can become a manageable part of governance rather than a last-minute disruption.
