The General Ledger (GL) is the central repository and master accounting record for a company’s financial data. It contains a complete history of all financial transactions, organised and summarised by individual accounts as defined in the company’s Chart of Accounts.
Purpose and Function
The primary purpose of the GL is to compile and categorise all financial transactions to provide the necessary data for preparing key financial statements, including the Balance Sheet, Income Statement, and Statement of Cash Flows. It serves as the core of a company’s financial records, ensuring accuracy through the principles of double-entry bookkeeping where total debits must equal total credits.
Key Components:
- Accounts: The GL is comprised of all individual accounts a business uses, typically categorised into Assets, Liabilities, Equity, Revenue, and Expenses.
- Debits and Credits: Each transaction is posted to the ledger as a debit to one account and a corresponding credit to another, keeping the accounting equation in balance.
- Trial Balance: At the end of an accounting period, the balances of all GL accounts are summarised into a trial balance to verify mathematical accuracy before preparing the official financial statements.
Relationship to Other Records
Transactions are initially recorded chronologically in subsidiary ledgers or journals (e.g., sales journal, purchase journal). These entries are then periodically posted (summarised and transferred) to the General Ledger, which organises the data by account rather than by date. The GL is the ultimate source of truth for a company’s financial position.
