What is a general ledger?
The general ledger is the master record of a business's accounts, holding every transaction sorted into categories such as sales, expenses, assets and liabilities.
What general ledger means
In double-entry bookkeeping, every transaction affects at least two accounts. The general ledger, also called the nominal ledger, is where all of those accounts live. Each one, such as sales, rent, bank, VAT or loans, has a running list of entries and a balance.
The list of accounts is called the chart of accounts. It is organised into five groups: income, expenses, assets, liabilities and equity. Income and expense accounts produce the profit and loss account; the rest produce the balance sheet.
How it works
Most entries arrive automatically. A sales invoice in Xero or QuickBooks posts to sales, VAT and accounts receivable. A bank feed transaction you categorise posts to the bank account and to the relevant expense. Manual journals are used for year-end adjustments such as depreciation and accruals.
The sales ledger and purchase ledger hold the detail for each customer and supplier. Their totals feed control accounts in the general ledger.
Example
A business pays £1,200 rent including £200 VAT from its bank account. The general ledger records:
| Account | Debit | Credit |
|---|---|---|
| Rent (expense) | £1,000 | |
| VAT (input VAT) | £200 | |
| Bank (asset) | £1,200 |
Debits equal credits, so the ledger stays in balance. At the month end, listing every account's balance gives a trial balance, which is the starting point for the accounts.
Why it matters for your business
Every report you rely on, from management accounts to your VAT return and year-end accounts, comes from the general ledger. If transactions are posted to the wrong accounts, the reports are wrong too: overheads look higher or lower than they are, VAT is misreported, or profit is distorted. A clear, consistent chart of accounts and regular review of the ledger keep the figures trustworthy.
HMRC can ask to see your records, and Making Tax Digital requires VAT records to be kept digitally, which in practice means a properly maintained ledger in accounting software.
Keeping it clean
Common problems include duplicate accounts for the same cost, a suspense account that never gets cleared and personal spending coded as business expenses. A quick monthly review of balances that look odd catches these before the year end.
Common questions
Yes. In the UK the two terms are used interchangeably. Both mean the main set of accounts that holds every income, expense, asset, liability and equity balance, from which the trial balance and the financial statements are prepared.
Any business using double-entry bookkeeping has one, and all accounting software maintains it automatically. Very small sole traders using simple cash records may not, but a limited company needs proper double-entry records to prepare its statutory accounts.
