An audit of finances systematically evaluates a company's financial statements to ensure accuracy and compliance with accounting standards like GAAP or IFRS. Key steps include planning, internal control review, substantive procedures, and evaluation/reporting, culminating in an audit report that may indicate the financial status of the company. Audited financial statements ensure accountability, verify internal data accuracy, and provide insights for stakeholders, though audits do not guarantee complete accuracy or long-term viability of the business.
