An Auditor is a professional that companies hire to review their financial documents, data, statements and accounting entries for accuracy and legal compliance. Auditors research and gather information from an organization’s account balances, various financial statements, balance sheets, financial reporting systems and tax returns. Using this information, Auditors ensure there are no gross errors or fraud and that the company’s financial data is presented in a fair and accurate way. These financial professionals work either as independent contractors or are hired as part of a company’s financial department.
