General Ledger
Also known as: GL, The Books
The general ledger is the complete record of every transaction your business has posted, organized by account.
What it actually means
The general ledger is the underlying record everything else is derived from. Each transaction is posted to accounts drawn from your chart of accounts, and every report — profit and loss, balance sheet, cash flow — is a view assembled from those postings. When a number on a report looks wrong, the ledger is where you go: drilling into a line shows the individual entries behind it with dates, vendors, and amounts. Modern accounting software maintains the ledger automatically as you categorize, but it remains the authoritative record, and an audit, a loan application, or a vendor dispute all end up looking at it.
Clicking a $3,100 advertising total on your P&L opens the ledger entries behind it: eleven charges, one of them a duplicate.
When a P&L line looks off — advertising at twice what you expected — the ledger is where you find the answer, usually a miscategorized transaction or a duplicate pulled in twice by a bank feed.
