Preparing for an external audit often involves gathering information from several departments, reviewing accounting records, and ensuring that important transactions can be traced to supporting documents. When these records are scattered, incomplete, or difficult to access, the audit may take longer than expected. A well-organised documentation process, on the other hand, helps auditors perform their procedures efficiently and allows company representatives to respond to enquiries with greater confidence.
For businesses preparing for a Financial Statement Audit, knowing which documents are commonly requested is a practical starting point. The exact requirements depend on the company’s operations, financial activities, and reporting circumstances, but most engagements involve a core collection of accounting, banking, corporate, and operational records. Preparing these materials before fieldwork begins can reduce avoidable delays and support a more orderly review.
1. General Ledger and Trial Balance
The general ledger and trial balance form the foundation of the financial information presented for audit.
The general ledger contains details of transactions recorded across the company’s accounts, while the trial balance summarises the closing balances of those accounts at a particular date.
Auditors use these records to understand how financial statement figures have been compiled and to select transactions for further examination.
Businesses should prepare:
- The final trial balance for the reporting period.
- Detailed general ledger listings.
- Opening balance information.
- Journal entry schedules.
- Supporting explanations for significant adjustments.
- Reconciliations between the trial balance and financial statements.
It is also useful to ensure that the accounting records are updated before submitting them. Unposted transactions and unexplained differences can create additional questions during the audit.
2. Bank Statements and Reconciliation Schedules
Bank documentation helps auditors examine the company’s cash balances and related transactions.
The finance team should generally have the following available:
- Bank statements covering the financial year.
- Bank reconciliation statements.
- Details of outstanding deposits and payments.
- Records of transfers between bank accounts.
- Bank confirmation information, where requested.
- Documentation relating to fixed deposits and other bank facilities.
Reconciliations should explain differences between the cash balance in the accounting records and the amount shown by the bank.
For example, an issued cheque that has not yet cleared may explain a timing difference. However, an unexplained adjustment or an old outstanding item may require further investigation.
3. Sales Invoices and Customer Records
Revenue is a significant part of many companies’ financial statements, so auditors often request documents that demonstrate how sales transactions were recorded.
Relevant records may include:
- Sales invoices.
- Customer contracts and agreements.
- Credit notes and sales returns.
- Delivery orders or proof of service completion.
- Customer statements.
- Accounts receivable ageing reports.
- Records of payments received after year-end.
These documents help auditors assess whether selected revenue transactions are supported and recognised in the appropriate accounting period.
Companies providing services should also retain agreements, project records, timesheets, or other evidence relevant to the work performed, where applicable.
4. Purchase Invoices and Supplier Documentation
Purchase records provide evidence for expenses, inventory acquisitions, and amounts owed to suppliers.
Commonly requested documents include supplier invoices, purchase orders, goods received notes, payment vouchers, and supplier statements.
Auditors may compare selected entries in the accounting records with these documents to determine whether the transactions are genuine, properly authorised, and recorded in the correct period.
Businesses should also prepare an accounts payable ageing report showing outstanding supplier balances.
This can help the audit team identify overdue amounts, investigate unusual balances, and consider whether liabilities have been recorded completely.
5. Payroll and Employee-Related Records
Employee costs can represent a substantial expense for businesses with permanent staff, contract employees, or other workforce arrangements.
Payroll documentation allows auditors to examine selected salary payments, deductions, and employee-related obligations.
Depending on the company’s circumstances, relevant records may include:
- Monthly payroll summaries.
- Employee salary registers.
- Employment contracts.
- Records of bonuses and commissions.
- Leave and other employee benefit schedules.
- Payroll payment records.
- Relevant statutory contribution documentation.
For Singapore companies, this may include applicable Central Provident Fund (CPF) contribution records and other employment-related documentation.
Personal employee information should be shared through appropriate secure channels and only to the extent necessary for the audit.
6. Fixed Asset Register and Supporting Documents
Companies that own property, equipment, vehicles, or other long-term assets should maintain an updated fixed asset register.
This register usually records the asset description, acquisition date, original cost, accumulated depreciation, and carrying amount.
Auditors may request:
- Fixed asset schedules.
- Purchase invoices.
- Disposal documents.
- Depreciation calculations.
- Records of asset transfers.
- Relevant ownership or registration documents.
- Supporting information for impairment assessments, where applicable.
The documentation helps the auditor assess whether assets have been recorded appropriately and whether depreciation and disposal entries are supported.
Where significant additions or disposals occurred during the year, management should ensure that the relevant transaction details are readily available.
7. Inventory Records and Stocktake Information
Inventory documentation is particularly important for retailers, wholesalers, distributors, and manufacturing businesses.
The company should prepare stock listings showing quantities and recorded values at the reporting date. Supporting documents may include purchase records, costing schedules, stock movement reports, and inventory adjustment records.
Other useful information includes:
- Physical stocktake instructions.
- Final stocktake results.
- Records of damaged or obsolete goods.
- Inventory ageing reports.
- Costing calculations.
- Goods received and delivery documentation.
Auditors may attend a physical inventory count or perform alternative procedures, depending on the circumstances and audit requirements.
Businesses should retain records explaining differences between physical quantities and accounting balances, together with any resulting adjustments.
8. Loan Agreements and Financing Records
Borrowings and other financing arrangements can affect a company’s liabilities, interest expenses, cash flow, and financial statement disclosures.
The audit team may request:
- Signed loan agreements.
- Bank facility letters.
- Repayment schedules.
- Interest calculation details.
- Bank statements showing loan movements.
- Records of security or guarantees.
- Documentation of covenant requirements, where relevant.
These records help establish the terms of the financing arrangements and whether outstanding amounts have been classified and disclosed appropriately.
If the company entered into new financing arrangements or made significant repayments during the year, the related documents should be included in the audit preparation files.
9. Corporate and Statutory Records
Corporate documentation provides information about the company’s legal structure, governance decisions, and significant events.
Depending on the engagement, auditors may request:
- Company constitution.
- Register of members and relevant ownership information.
- Details of directors and company officers.
- Board and shareholder meeting minutes.
- Records of share allotments or transfers.
- Relevant resolutions and approvals.
- Statutory filings and corporate records.
These documents may help auditors understand significant transactions, changes in ownership, and decisions that affect the company’s financial reporting.
Board minutes can be especially useful when examining major investments, borrowings, asset disposals, or other significant business arrangements.
10. Tax Computations and Relevant Correspondence
Tax-related records can help auditors understand the company’s tax balances and the relationship between accounting profit and taxable income.
Common documents include:
- Current tax computations.
- Relevant tax returns.
- Notices of assessment.
- Records of tax payments.
- Correspondence with the tax authority.
- Supporting schedules for tax-related balances.
- Information about deferred tax, where applicable.
For Singapore businesses, relevant records may include correspondence and documents relating to the Inland Revenue Authority of Singapore (IRAS).
The audit team may examine whether tax balances are appropriately recognised and whether relevant financial statement disclosures have been made.
11. Contracts and Agreements Affecting Financial Reporting
Some important financial transactions cannot be understood fully from invoices or ledger entries alone. Contracts often explain the underlying terms and obligations.
Depending on the company’s activities, auditors may request:
- Major customer and supplier agreements.
- Property rental or lease agreements.
- Service contracts.
- Financing and guarantee agreements.
- Joint venture arrangements.
- Insurance policies.
- Significant settlement agreements.
These documents can be relevant when evaluating revenue recognition, lease accounting, contractual commitments, provisions, and other reporting matters.
Management should identify agreements entered into, renewed, or amended during the financial year, particularly those involving significant financial commitments.
12. Subsequent Events and Going Concern Information
Events occurring after the reporting date may affect financial statement recognition or disclosure. Auditors therefore consider relevant developments between the financial year-end and the date of the auditor’s report.
Useful documentation may include:
- Significant post-year-end sales and purchase transactions.
- Details of major payments and receipts.
- New financing arrangements.
- Information about legal disputes.
- Updates on significant customer or supplier difficulties.
- Cash flow forecasts.
- Budgets and financial projections.
- Management’s assessment of going concern.
For example, a major customer entering financial difficulty after year-end may be relevant when considering the recoverability of an outstanding receivable, depending on the circumstances.
The auditor evaluates these matters in accordance with the applicable auditing and financial reporting requirements.
Organising Documents Before the Audit Begins
Collecting the right records is only part of the preparation process. How the information is arranged can also influence how efficiently the audit progresses.
A practical approach is to create a document folder for each major financial statement category. The folders can contain the relevant schedules, reconciliations, supporting invoices, and explanations.
Businesses may find the following practices useful:
- Use consistent file names: Identify documents by reporting period, account category, and document type.
- Prepare a document checklist: Track which records have been submitted and which remain outstanding.
- Assign responsible employees: Make it clear who will handle requests relating to banking, payroll, sales, purchases, and other areas.
- Check schedules before submission: Ensure that supporting schedules agree with the accounting records.
- Explain unusual balances: Provide brief written explanations for significant movements or uncommon transactions.
- Protect confidential information: Use suitable access controls when sharing sensitive corporate or employee documents.
A centralised document repository can also make it easier for authorised employees and the audit team to locate relevant information.
Why Documentation Quality Matters
Audit documentation is important because auditors need sufficient appropriate evidence to support their conclusions. A financial balance without adequate supporting information may require additional procedures before the auditor can reach a conclusion.
Incomplete documentation can also lead to repeated requests, longer review periods, and unresolved audit matters.
For management, maintaining organised records offers benefits beyond the audit itself. It supports better transaction monitoring, improves accountability, and makes financial information easier to review throughout the year.
However, preparing every possible document does not mean that all records will automatically be examined. Auditors determine the nature and extent of their procedures based on the engagement’s circumstances and assessed risks.
Conclusion
A smooth financial statement audit depends partly on the company’s ability to provide complete, organised, and relevant supporting records. General ledgers, bank statements, sales and purchase documents, payroll information, asset schedules, corporate records, and financing agreements are among the materials commonly requested.
The precise document list will vary according to the company’s activities and reporting requirements. By maintaining these records throughout the year, assigning clear responsibilities, and responding promptly to audit enquiries, businesses can make the review process more manageable. Good documentation also contributes to dependable accounting information and a stronger financial reporting system.
