A ledger is a record for economic transactions that includes cash, accounts receivable, inventory, fixed assets, accounts payable, accrued expenses, debt, equity, revenue, costs, salaries, wages, expenses, depreciation, and so on. In short, the book in which accounts are maintained is called a ledger. It is the primary record used by banks and other financial institutions to reconcile book balances. All the debits and credits during an accounting period are calculated to make the ledger balance.
The financial statements of banks, financial institutions, and enterprises are compiled using ledger accounts.
