An auditor is a professional who examines and verifies a company's financial records to ensure accuracy and compliance with laws. They help organizations maintain transparency and trust by checking for errors or fraud in financial statements. Auditors can work for private firms, government agencies, or as independent consultants. There are two main types of auditors: internal and external. Internal auditors work within a company to improve processes and reduce risks, while external auditors are independent and provide an objective assessment of the company's financial health. Both types play a crucial role in maintaining the integrity of the financial system.
