Financial statements are the fundamental document by which quality business decisions are made. In order to be used as a basis for making business decisions, financial statements must be objective and realistic in expressing financial performance and financial position in business. Examination of the reality and objectivity of financial statements is carried out by hiring an authorized auditor who gives his independent opinion in the form of an independent auditor's report. Therefore, the purpose of the audit of financial statements is to enable the authorized auditor to present an opinion on the compliance of financial statements with all essential determinants of financial reporting in order to achieve a realistic picture of the company's operations. The relationship between auditing and financial statements is extremely important to external stakeholders. Namely, external stakeholders want to be sure that the information contained in the financial statements is correct, which is precisely what the audit allows them to do. Ensuring the quality of information contained in financial statements avoids the risk of making wrong business decisions that can result in large losses and irreparable damage. In the framework of this thesis, an attempt will be made to present and explain the process of auditing financial statements in such a way as to first analyze the importance of basic financial statements as a process of successful management, then the importance of legal frameworks and codes of professional ethics in the audit process is expressed, and at the end of the paper, the components are described parts and the revision process itself.
