How is a Trial Balance Used in Accounting?
A trial balance is a report listing all general ledger accounts and their debit or credit balances at a point in time. It’s a key checkpoint in the accounting cycle because it supports period-end review and is commonly used as the starting point for preparing financial statements.
- A trial balance summarises GL balances and checks that total debits equal total credits.
- It supports financial statement preparation, review, and reconciliation workflows.
- A balanced trial balance does not guarantee the accounts are correct—reconciliations still matter.
What a trial balance shows
A typical trial balance includes
- account codes and account names
- debit and credit balances per account
- a total debit and total credit figure (which should match)
Trial balances can be produced at month-end, quarter-end, year-end, or any date for internal review.
Why it’s important
The trial balance provides a high-level map of the ledger. Finance teams use it to:
- validate that postings are mathematically consistent
- review unusual movements and unexpected balances
- identify accounts needing reconciliation or investigation
- support financial statement drafting and management reporting
It also helps auditors and reviewers navigate the ledger quickly.
Trial balance vs general ledger
The general ledger contains all transaction detail and journals. The trial balance is a summarised view of the GL by account. You often drill from trial balance to GL detail to explain movements.
Common issues even when it balances
A trial balance can “balance” while still containing errors, such as:
- transactions posted to the wrong account or dimension
- missing accruals or cut-off errors
- duplicate postings offsetting each other
- incorrect VAT/tax treatment
- balance sheet items not reconciled to external evidence
That’s why the trial balance is a starting point, not the finish line.
Best practices for review
- Compare period vs period and flag outliers
- Review suspense and clearing accounts routinely
- Ensure balance sheet accounts are reconciled to evidence (bank, AR/AP, tax, fixed assets)
- Document explanations for significant movements
Does a balanced trial balance mean the accounts are correct?
No. It only proves debits equal credits; classification and completeness issues can still exist.
When should a trial balance be produced?
At each reporting cut-off—monthly for management reporting and at year-end for statutory accounts.
Why do auditors request trial balances?
They provide a structured overview of balances and a starting point for testing and analysis.
