ISA 2004, or the International Standards on Auditing 2004, is a set of auditing standards issued by the International Auditing and Assurance Standards Board (IAASB). These standards provide guidance to auditors on how to conduct audits of financial statements.
ISA 2004 is important because it helps to ensure that audits are conducted in a consistent and high-quality manner. This helps to improve the reliability of financial statements and to protect investors and other stakeholders.
