The general ledger serves a number of important functions for the business. It helps accountants prepare a trial balance to make sure that all debits and credits balance out. This process helps accountants identify errors, unusual transactions, and fraud, and it provides an opportunity to make corrections.The general ledger is especially important because it allows the business to produce financial statements, like income statements and the balance sheet, which provides detailed information for accountants, managers, and investors to make informed analyses about the business and its performance.
