How trial balance works
At the end of a period, every account balance from the general ledger, cash, accounts receivable, revenue, expenses, is pulled into one list. Debit balances go in one column and credit balances go in another. If the two columns do not add up to the same total, there is an error somewhere in the books. This step is usually one of the first done during month-end close, before any financial statements are finalized.
Once the trial balance is in balance, accountants review it for accounts that look off, such as a negative balance where there should not be one, then use it to build the balance sheet and income statement. It is a quick check point, not a full guarantee that every entry is correct, since offsetting errors can still hide inside a balanced trial balance. Comparing the current trial balance to the prior period also helps catch an account that moved in an unexpected direction.
Example
A small firm's trial balance shows total debits of $84,200 and total credits of $82,900, a $1,300 difference. Review finds a $1,300 rent payment posted only as a debit to rent expense with no matching credit to cash. Adding the missing credit brings both columns to $84,200, and the trial balance is now in balance.
Trial balance in QuickBooks Online vs Xero
QuickBooks Online generates a trial balance automatically under Reports, pulling live balances from the general ledger. Xero offers the same report under its Accounting reports section, with the option to compare periods side by side. Neither tool requires manual entry, since the report updates as transactions are posted. Both tools let you drill into any account balance directly from the trial balance report for a closer look.
