Accounting can be divided into several fields including financial accounting, management accounting, auditing, and tax accounting.[5][6] Financial accounting focuses on the reporting of an organization's financial information, including the preparation of financial statements, to external users of the information, such as investors, regulators and suppliers;[7] and management accounting focuses on the measurement, analysis and reporting of information for internal use by management.[1][7] The recording of financial transactions, so that summaries of the financials may be presented in financial reports, is known as bookkeeping, of which double-entry bookkeeping is the most common system.
