What it means
Bookkeeping happens in two stages. Transactions are first written into a journal in date order, then posted into the ledger where they are grouped by account, and the general journal is the catch-all journal that handles anything the routine books do not.
The reason it matters outside the accounts department is that the general journal is where judgement enters the numbers. Sales invoices and supplier bills mostly record themselves, but accruals, provisions, reclassifications and write-offs are typed in by a person who decided they were needed.
Anyone reading a set of accounts is really reading the outcome of those decisions. A typical entry has five parts: the date, the account to be debited, the account to be credited, the amounts, and a short narration explaining why the entry exists.
The narration is the piece people skip and auditors read first, because it is the only place the reasoning is recorded. Most businesses also run special journals for high-volume routine activity, such as a sales journal, a purchases journal and a cash receipts journal.
In modern accounting software these are hidden behind invoice and payment screens, so the general journal is often the only journal a finance manager touches directly, usually at month end. The nuance worth knowing is that manual journal entries carry more risk than any other posting type, because they can move large amounts between accounts without a supplier or customer document behind them.
Sensible controls require a second person to review and approve entries above a set value.
In practice
Real-world examples.
Example
A manufacturer discovers in November that a $15,000 machine repair was posted to the equipment account instead of repairs expense. A general journal entry debits Repairs Expense $15,000 and credits Equipment $15,000, with a narration citing the original invoice number.
Example
A consultancy has delivered $48,000 of work in December that will not be invoiced until January. The bookkeeper raises a journal entry debiting Accrued Revenue $48,000 and crediting Revenue $48,000 so the income lands in the year it was earned.
Example
Two founders inject $250,000 of start-up capital into a new company. Because there is no sales or purchase document involved, the transaction is recorded straight into the general journal, debiting Cash at Bank and crediting Share Capital.
Think of it
“The general journal is the catch-all record for transactions that don't fit elsewhere-adjustments and unusual items.
Formula
Calculation
The governing rule is not a formula so much as an equality: Total debits = Total credits for every entry.
A design agency buys a photography rig for $60,000 on 1 March, paying $20,000 from the bank and signing a note payable for the remaining $40,000. The journal entry debits Equipment $60,000, credits Cash at Bank $20,000 and credits Notes Payable $40,000. The credits total $20,000 + $40,000 = $60,000, which matches the single debit, so the entry balances.
At the end of March the agency records depreciation on the same rig over a five year life with no residual value. Annual depreciation is $60,000 / 5 = $12,000, so the monthly charge is $12,000 / 12 = $1,000. The journal entry debits Depreciation Expense $1,000 and credits Accumulated Depreciation $1,000, and once again debits equal credits.Case study
Seen in the real world.
Norvell Instruments is a fictional maker of laboratory equipment used here purely as an illustrative case. Its year-end profit came in $340,000 above forecast, and the chief executive asked the finance team to explain the surprise before the board meeting.
The answer sat in the general journal. A single manual entry had reversed a $340,000 warranty provision on the grounds that claims had fallen, but the narration said only "provision adjustment" and no one had reviewed it. When the team went back to the claims data, the fall was explained by a product launch delay rather than better reliability, so the provision was reinstated.
In this illustrative example the company changed one thing: any journal entry above $50,000 now needs a written rationale and a second approver. The general journal did not cause the problem, but it was the only place the problem was visible.
Watch out
Common mistakes.
- Confusing the general journal with the general ledger, when the journal is the chronological record of entries and the ledger is the same information regrouped by account.
- Posting journal entries without a narration, which leaves nobody able to explain six months later why an amount was moved between two accounts.
- Using manual journal entries to force a set of accounts to agree to a target figure, rather than finding and correcting the underlying transaction.
Questions
People also ask.
Do small businesses still need a general journal?
Yes, because even a business that runs entirely on cloud software will need adjusting entries for depreciation, accruals and owner contributions that no invoice screen produces.
What is the difference between a journal entry and a transaction?
A transaction is the underlying economic event, while the journal entry is the formal bookkeeping record of that event expressed as balanced debits and credits.
Can a journal entry have more than two lines?
Yes, an entry can involve any number of accounts, and the only requirement is that the total of the debit lines equals the total of the credit lines.
