External auditors are independent professionals who examine a company's financial statements and records to ensure accuracy and compliance with accounting standards. They provide an objective assessment of a company's financial health, helping stakeholders, such as investors and regulators, make informed decisions. These auditors typically work for accounting firms and are hired by organizations to conduct audits on a periodic basis. Their findings are documented in an audit report, which can highlight any discrepancies or areas for improvement, ultimately enhancing the credibility of the company's financial reporting and fostering trust among stakeholders.
