An audit is a systematic examination of an organization's financial statements, internal controls, or compliance with specific regulations. The primary goal is to provide an independent opinion on the accuracy and fairness of the presented information. Proper documentation serves as the evidence auditors need to verify transactions, account balances, and the overall financial health of the entity. Without it, the audit process can be delayed, become more expensive, and may even result in a qualified or adverse audit opinion. Understanding what to prepare streamlines the entire procedure and demonstrates a commitment to transparency and good governance.

The Foundation: Core Financial Statements and General Documents

This category includes the fundamental reports that paint a broad picture of your organization's financial position. Auditors will use these as a starting point for their analysis.

1. Financial Statements and Supporting Schedules

These are the centerpiece of any financial audit. You must provide the final versions of the key statements, along with the detailed schedules that back them up.

• Balance Sheet: A snapshot of your company's assets, liabilities, and equity at a specific point in time.
• Income Statement: Shows your revenue, expenses, and profit or loss over a period.
• Statement of Cash Flows: Details the movement of cash from operating, investing, and financing activities.
• Statement of Changes in Equity: Explains any changes in the owners' equity throughout the period.
• Supporting Schedules: These include detailed listings for accounts like prepaid expenses, fixed assets, accrued liabilities, and equity accounts.

2. Entity Constitution and Governance Records

These documents establish the legal and operational framework of the organization.

• Articles of Incorporation/Organization: The legal document that created the entity.
• Bylaws or Operating Agreement: The rules governing the internal management of the company.
• Minutes from Board of Directors and Shareholder Meetings: These are crucial as they record major decisions like approval of the financial statements, dividend declarations, appointment of officers, and significant contracts.

Verifying Transactions: The Detailed Evidence

Auditors perform substantive testing by digging into the details of your transactions. The following documents provide the necessary evidence to support the amounts shown in your financial statements.

1. Bank and Investment Records

Direct confirmation from financial institutions is vital for verifying cash balances.

• Bank Statements: For all accounts for the entire audit period.
• Bank Reconciliations: The prepared reconciliations for each account at the end of the period.
• Loan Agreements and Statements: Documents for all outstanding loans, lines of credit, and related covenants.
• Brokerage Statements: For any investment portfolios.

2. Accounts Receivable and Revenue Documentation

To verify that recorded revenue is valid and collectible, auditors will need:

• Aged Accounts Receivable Report: A detailed listing of customer invoices and their ages.
• Sales Invoices and Shipping Documents: Evidence that goods were shipped or services were rendered.
• Credit Memos and Write-off Approvals: Documentation for any adjustments to the receivable balance.

3. Accounts Payable and Expense Verification

Auditors need to ensure that liabilities and expenses are recorded completely and accurately.

• Aged Accounts Payable Report: A listing of outstanding bills to suppliers.
• Vendor Invoices: Supporting documents for major expenses.
• Accrual Schedules: Documentation for expenses incurred but not yet paid, such as wages payable or utilities.

4. Fixed Asset and Inventory Records

For companies with significant physical assets, this documentation is essential.

• Fixed Asset Register: A detailed list of all owned assets, including cost, date of purchase, and accumulated depreciation.
• Purchase Invoices for Capital Assets: Proof of the original cost of equipment, vehicles, and property.
• Depreciation Schedules: Calculations showing how the asset value is being expensed over time.
• Physical Inventory Count Sheets: Records from the most recent inventory count.
• Inventory Valuation Summary: Documentation supporting the cost assigned to ending inventory.

Supporting the Big Picture: Legal, Tax, and Internal Control Documents

Beyond transactional details, auditors must assess contingent liabilities, tax compliance, and the control environment.

1. Legal and Contractual Agreements

These documents help identify potential liabilities that may not yet be recorded on the balance sheet.

• Lease Agreements: For both operating and finance leases (e.g., office space, equipment).
• Major Customer and Vendor Contracts: Long-term agreements that could impact future financial performance.
• Loan Agreements and Covenants: As mentioned earlier, these are critical for debt compliance.
• Letters from Lawyers: Regarding ongoing or threatened litigation (often obtained via a legal letter request from the auditors).

2. Tax Compliance Records

Auditors need to verify that the company is compliant with all relevant tax authorities.

• Income Tax Returns: Filed federal, state, and local returns for the past several years.
• Sales Tax Returns: If applicable.
• Payroll Tax Filings: Documentation related to employee taxes.
• Correspondence with Tax Authorities: Any letters from the IRS or other tax bodies.

3. Internal Control Documentation

For larger audits, understanding the company's internal controls is a key part of the process.

• Accounting Manuals and Policies: Written procedures for key processes like revenue recognition and expense reporting.
• Organizational Charts: Showing lines of authority and responsibility within the finance department.
• Evidence of Management Review: Such as signed-off bank reconciliations and monthly financial package reviews.
