Total debits should equal total credits. Bookkeepers run it during the month-end or year-end close to check the ledger before preparing financial statements. Last updated October 8, 2026 Updated October 8, 2026 · By [Robert Breen](https://learn.ynteractive.com/content/about) ## Why it matters for a small business The trial balance is the bookkeeper's first sanity check. If debits and credits do not match, something was posted wrong, and it is far easier to find this week than after the tax return is filed. It also gives an owner a one-page view of every balance, which makes odd numbers jump out: a cash account that is negative, or a suspense account that keeps growing. It has limits. A trial balance can match perfectly while an expense sits in the wrong account, a bill is entered twice on both sides or a whole transaction is missing. That is why it comes after [bank reconciliation](https://learn.ynteractive.com/content/glossary/bank-reconciliation) and before adjustments, not instead of them. Reading one well is a skill, so lean on your accountant for anything that looks off. ## In a real lesson: Turn a Client Meeting into Action Items and a Follow-Up Email (Accounting Firms) No Stepthrough lesson runs a trial balance, but the [Summarize a Client Meeting lesson](https://learn.ynteractive.com/content/chatgpt-client-meeting-recap-accounting-firm) shows the work that has to happen before one is useful. In a Q3 review between Millbrook Accounting and its client Cedar Lane Landscaping (both made up), Tom Alvarez says he has "reconciled the checking account and the credit card through August." He then flags a problem: "There are twenty-three transactions sitting in uncategorized." A trial balance run that day would balance, because each of those charges has two sides, yet one uncategorized line would hold all of them. That is the kind of number a reviewer spots on a trial balance and asks about. ChatGPT's job in the lesson is the recap: decisions, an action items table with owner and due date, and a follow-up email. Getting the missing statements and the uncategorized list cleared on a date is what lets the close, and the trial balance, happen on time.

A balance sheet is a financial statement showing only assets, liabilities and equity at a date. ### Unadjusted vs adjusted trial balance The unadjusted version comes straight from the ledger. The adjusted version is run after month-end entries such as accruals, prepaids and depreciation, and it feeds the financial statements. ## Tips - Reconcile bank and card accounts before you run it. - Scan for accounts with an unusual sign, like a negative cash balance or a credit balance in an expense account. - Ask AI to explain an account name or draft questions for your bookkeeper, not to decide adjustments. ## Related terms [General ledger](https://learn.ynteractive.com/content/glossary/general-ledger) · [Journal entry](https://learn.ynteractive.com/content/glossary/journal-entry) · [Closing the books](https://learn.ynteractive.com/content/glossary/closing-the-books) · [Bank reconciliation](https://learn.ynteractive.com/content/glossary/bank-reconciliation) · [Chart of accounts](https://learn.ynteractive.com/content/glossary/chart-of-accounts) · [Accrued expense](https://learn.ynteractive.com/content/glossary/accrued-expense) ## More Business terms [Turnaround time](https://learn.ynteractive.com/content/glossary/turnaround-time) · [Two-way match](https://learn.ynteractive.com/content/glossary/two-way-match) · [Upsell](https://learn.ynteractive.com/content/glossary/upsell) · [Utilization rate](https://learn.ynteractive.com/content/glossary/utilization-rate) ## Where you use it: free lessons - [Turn a Client Meeting into Action Items and a Follow-Up Email (Accounting Firms)](https://learn.ynteractive.com/content/chatgpt-client-meeting-recap-accounting-firm) (ChatGPT, 9 min) - [Build an AI Agent That Categorizes Business Expenses](https://learn.ynteractive.com/content/n8n-ai-agent-categorize-business-expenses-google-sheets) (n8n, 12 min) ## More free tutorials [AI for Finance](https://learn.ynteractive.com/content/industry/finance) ## Frequently asked questions **What is the purpose of a trial balance?** It checks that total debits equal total credits in the general ledger and gives a one-page list of every account balance. Bookkeepers use it to catch posting errors before preparing financial statements. **What errors does a trial balance not catch?** It misses errors that keep debits and credits equal: a transaction left out entirely, an entry posted to the wrong account, a duplicate entry or two mistakes that cancel each other out. **When do you prepare a trial balance?** At the end of each accounting period, usually monthly, and at year-end. Many teams run it before and after month-end adjusting entries, then use the adjusted version for reports.
