Trial Balance

A trial balance is a list of every account in your ledger with its closing debit or credit balance, where the debits and credits add up to the same total. It is the one report that proves the books are internally consistent — and the report your CPA will ask for before anything else.

What It Actually Proves, and What It Does Not

A balanced trial balance proves one thing: every transaction was entered with equal debits and credits. That is a real check, and it is a narrow one.

It does not prove the figures are right. A payment coded to the wrong expense account balances perfectly. Revenue recorded in the wrong month balances. An entire missing transaction balances, because it is missing from both sides. A trial balance that adds up tells you the arithmetic works, not that the accounting does.

That is worth saying because “it balances” is often treated as the end of the month-end close. It is closer to the beginning.

Where It Shows Up

At month end, as the starting point for review: you read down the trial balance looking for accounts whose balance makes no sense — a negative asset, a suspense account with anything in it, an expense account with a credit balance.

At year end, as the handover document. When a CPA asks for your books, what they generally want is a trial balance with supporting reconciliations, because it is the most compact complete picture of the ledger.

During due diligence or a loan review, because it shows every account rather than the summarised view a profit and loss gives.

What Goes Wrong

Treating balance as correctness. Covered above, and the commonest misunderstanding.

Accounts that should be empty and are not. A suspense account, a clearing account or undeposited funds with a lingering balance is a signal that something was parked and never resolved.

Balances with the wrong sign. A liability with a debit balance or an asset with a credit balance is almost always an error, and a trial balance is where you see it.

Nobody reading it. The most common failure is simply that the report is produced and not reviewed, so the signals it carries are never acted on.
