Journal entry

What is a journal entry, and how should you correct one once it's posted?

GlossaryUpdated 10 October 2026

Definition

A journal entry is a dated accounting record of a transaction, made up of debit and credit lines to specific accounts that must add up to the same total.

What is a journal entry made of?

Every transaction in double-entry bookkeeping is recorded as a journal entry with a date, a description and at least two lines. Some entries are created automatically by documents such as invoices and receipts; others, such as accruals or corrections, are entered by an accountant.

A customer pays an invoice by bank transfer

Example
Dr Bank
GBP 5,250
Cr Accounts receivable
GBP 5,250

Debits equal credits

GBP 5,250

Once posted, an entry shouldn’t be edited; it should be cancelled with a reversing entry and replaced, so the trail stays intact.

See books that keep themselves

Watch a goods receipt, a delivery and an invoice post their own journals in 1flux, then follow each ledger line back to its document.
