Ledger
A ledger is a record-keeping book or electronic system used to track and organize financial transactions. It serves as a central repository for recording and summarizing all the financial activities of a business or individual. Ledgers typically contain accounts that represent different categories of transactions, such as assets, liabilities, equity, revenue, and expenses. By maintaining a ledger, users can track the flow of money, monitor balances, and generate financial statements to assess the financial health and performance of an entity.
