A general ledger contains all the accounts for recording transactions relating to a company's assets, liabilities, owners' equity, revenue, and expenses. In modern accounting software or ERP, the general ledger works as a central repository for accounting data transferred from all subledgers or modules like accounts payable, accounts receivable, cash management, fixed assets, purchasing and projects. The general ledger is the backbone of any accounting system which holds financial and non-financial data for an organization. The collection of all accounts is known as ledger account.
