What Is General Ledger?
The master record of all accounts and journal entries.
Detailed Explanation
Invoices post to AR, revenue, and tax accounts. It feeds financial statements.
Example
Month-end closes reconcile the GL to bank and subledgers.
Why It Matters
Audit-ready books start with a disciplined GL.
Key facts
- The general ledger (GL) is the primary accounting record containing all financial transactions of a business, organized by account.
- Every transaction in the GL follows double-entry bookkeeping: each debit must equal a credit, ensuring the accounting equation (Assets = Liabilities + Equity) remains balanced.
- The GL is organized via the chart of accounts — a numbered list of every asset, liability, equity, revenue, and expense account.
- Modern accounting software (QuickBooks, Xero, NetSuite, etc.) automatically posts transactions to the GL from invoices, bills, and bank feeds.
- Period-end close involves reconciling the GL to bank statements, AR/AP subledgers, and inventory counts before producing financial statements.
How it shows up in practice
A small consulting firm's general ledger contains roughly 80 active accounts: Cash, AR, Equipment, AP, Accrued Wages, Owner's Equity, Revenue, Salaries, Rent, Software Subscriptions, etc. When they invoice a client $5,000, the system creates: Debit AR $5,000, Credit Revenue $5,000. When the client pays: Debit Cash $5,000, Credit AR $5,000. The GL records every penny moving through the business — and forms the basis for monthly financial statements.
Common mistakes
- Letting the GL get out of sync with subledgers (AR, AP, Inventory) — quarterly reconciliations should bring them back into agreement.
- Posting directly to controls accounts (like AR or AP control accounts) instead of through proper subledger entries — breaks the audit trail.
- Failing to close the GL at period end — leaves transactions in 'open' periods that can be modified, complicating audit.
- Using too few or too many GL accounts — too few obscures useful detail, too many creates posting confusion.
- Not backing up the GL before period-end close — data corruption at this stage is catastrophic.
Frequently asked questions
What's the difference between the general ledger and subledgers?
The GL contains summary balances for each account. Subledgers (AR, AP, Inventory, Fixed Assets) contain the detailed transactions that compose those summary balances. Subledgers must reconcile to the GL controls account at period end.
How is the GL different from the trial balance?
The GL is the comprehensive record of all transactions. The trial balance is a list of all GL account balances at a point in time, used to verify that debits equal credits before producing financial statements. The trial balance is derived from the GL.
Can I see my GL in QuickBooks/Xero?
Yes — both have 'General Ledger' or 'Detail by Account' reports that show every transaction posted to each account. Useful for investigating unusual balances or preparing audit schedules.
How long should I retain GL data?
Minimum 7 years in most U.S. tax jurisdictions; some industries (healthcare, financial services) require longer. Best practice: keep GL data permanently in your accounting system, even after migrating to new software.
What's GL automation?
GL automation refers to systems that auto-post transactions to the GL from source documents (invoices, bills, bank feeds, payroll runs) using rules instead of manual journal entries. Most modern accounting software does this for 80-95% of transactions.
