Key takeaways

• Prepare a trial balance at the end of each accounting period by listing all general ledger account balances in three columns (account names, debits, credits) to verify that total debits equal total credits before creating financial statements.
• Use trial balances to catch common bookkeeping errors like transcription mistakes, missing entries, and misclassified transactions before they affect your financial statements and business decisions.
• Create three types of trial balances during your accounting process: an unadjusted version to start closing books, an adjusted version after corrections that serves as the foundation for financial statements, and a post-closing version to confirm your ledger is ready for the next period.
• Implement accounting software to automate trial balance preparation and eliminate manual calculation errors, allowing you to generate accurate reports instantly and focus more time on reviewing accuracy rather than performing calculations.

What is a trial balance?

A trial balance is a financial report that lists the closing balances of all accounts in your general ledger at a specific point in time. It helps you verify that total debits equal total credits before preparing financial statements.

Many businesses create a trial balance as the first step in closing their books at the end of an accounting period. It's a quick check to catch fundamental errors before a full financial audit.

Components of a trial balance

A trial balance uses a simple three-column layout:

• Account names: all ledger accounts from your chart of accounts listed on the left
• Debit balances: assets and expense accounts in the middle column
• Credit balances: liabilities, capital, and income on the right

You can omit accounts you haven't used during the period. The totals of the debit and credit columns should match exactly.

Trial balance example

This trial balance format shows the closing balances of all accounts in the general ledger at the end of a financial period.

The account names go in the far left column. All debit and credit balances from the general ledger are recorded in the 'Debit' and 'Credit' columns accordingly. The debit and credit columns total the same amount.

Why trial balances matter for your business

A trial balance helps you catch bookkeeping errors before they become costly problems. By verifying that debits equal credits, you can trust that your financial records are accurate.

Trial balances matter for small businesses because they:

• Error detection: spot mathematical mistakes, missing entries, and transposition errors before preparing financial statements
• Compliance confidence: ensure your books are accurate for tax time, audits, and various reporting mandates, such as those from the Securities and Exchange Commission (SEC) for public companies
• Better decision-making: base business decisions on reliable financial data rather than flawed numbers
• Audit preparation: provide auditors with a clear summary of your account balances

Trial balances are especially valuable at the end of each accounting period. They serve as a checkpoint before you finalise financial statements and close your books.

Types of trial balances

There are three types of trial balances: unadjusted, adjusted, and post-closing. Each follows the same format but happens at a different stage of the accounting process:

• Unadjusted trial balance: gathers initial data to start closing the books and checks for obvious errors that need adjusting
• Adjusted trial balance: includes corrected entries and serves as the foundation for preparing financial statements
• Post-closing trial balance: confirms the ledger is ready for the next accounting period after temporary accounts are closed

Unadjusted trial balance

An unadjusted trial balance captures all initial data from your general ledger before any corrections. It records day-to-day transactions that can then be adjusted to balance the ledger.

Common adjustments include:

• Accruals: adding unpaid bills or earned revenue not yet recorded
• Deferrals: recognising income only when it's earned
• Depreciation: spreading the cost of assets like vehicles over several years

These adjustments give you a clearer view of your business's financial position.

Adjusted trial balance

An adjusted trial balance is a summary of final account balances after all adjusting entries have been made. You prepare it after the unadjusted trial balance but before creating financial statements.

This report serves as the foundation for your balance sheet, income statement, and other financial reports.

Post-closing trial balance

A post-closing trial balance verifies that all debit and credit balances are equal after you've closed temporary accounts. You prepare it after finalising all financial statements for the period.

During the closing process, balances from temporary accounts (revenue, expenses, and dividends) move into retained earnings. The post-closing trial balance confirms your general ledger is ready for the next accounting period with a clear separation from the previous one.

How to prepare a trial balance

Preparing a trial balance is straightforward. Follow these steps to create an accurate report:

1. Gather your general ledger balances

Collect the closing balances for all accounts in your general ledger.

2. List accounts and their balances

Record account names in the left column, with debit balances in the middle and credit balances on the right.

3. Total your debits and credits

Add up each column separately.

4. Verify that totals match

If debits equal credits, your books are balanced; if not, review your ledger entries for errors.

These steps produce an unadjusted trial balance. You'll then prepare an adjusted trial balance after making corrections, and finally a post-closing trial balance once your financial reports are finalised.

Trial balances are less formal than balance sheets, so you can prepare them as often as needed. Accounting software like Xero automates this process, helping you avoid clerical mistakes and produce regular trial balances effortlessly.

Common trial balance errors

Simple mistakes can throw off your trial balance. Watch out for these common errors:

• Transcription errors: mistyping figures, such as entering $500 as $5,000
• Omission errors: transactions left out of the accounts entirely
• Misclassification errors: transactions recorded under the wrong account headings

Even minor errors can alter your financial statements and lead to business decisions based on incorrect information.

How to correct trial balance errors

Simple mistakes are easy to fix with the right approach:

• Recheck your numbers: review your trial balance thoroughly, take a break, and get a second pair of eyes to spot typos
• Verify your ledger: confirm ledger figures are correct before inputting them, and re-verify any figures that seem unreliable
• Use accounting software: use tools like Xero to prevent mistyped entries and speed up calculations, giving you more time to check accuracy

Trial balance vs balance sheet

A trial balance and a balance sheet both show financial information, but they serve different purposes:

• Trial balance: an internal bookkeeping report that lists all general ledger balances to check for mathematical errors
• Balance sheet: a formal financial statement that summarises your business's assets, liabilities, and owner's equity

The trial balance is a working document used to verify accuracy. The balance sheet is a polished report that shows your business's financial position to stakeholders, lenders, and investors.

How trial balances improve your financial reporting

Trial balances help accountants verify that your books are accurate before preparing financial statements. They're also an important document for auditors.

Your bookkeeper or accountant checks that debit and credit column totals match. If they don't, there may be a missing entry or an error when copying from the general ledger.

Once any mistakes are corrected, the adjusted trial balance becomes the foundation for your balance sheet, income statement, and other financial reports.

A balanced trial balance doesn't guarantee error-free books. Missing transactions or incorrect account classifications can still exist even when totals match.

FAQs on trial balances

Common questions about trial balances and how they fit into your accounting process.

What are the three rules of trial balances?

• Total debits must equal total credits: this confirms your double-entry bookkeeping is mathematically accurate. Franciscan friar Luca Pacioli first codified this system in a 1494 mathematics textbook
• Use the correct chart of accounts: categorise transactions under the right account headings
• Enter data accurately: avoid typos, omissions, and transposition errors when recording figures

How often should you prepare a trial balance?

Most businesses prepare a trial balance at the end of each accounting period, whether monthly, quarterly, or annually. You can also run one whenever you need to verify your books are accurate, such as before a major financial decision or audit.

Can accounting software automate trial balances?

Yes. Accounting software like Xero automatically generates trial balances from your general ledger data. This eliminates manual calculations, reduces errors, and lets you produce accurate reports in seconds.

What happens if my trial balance doesn't balance?

If debits and credits are unequal, review your bookkeeping to find the discrepancy. Check for transcription mistakes, missing entries, or transactions recorded in the wrong accounts. Review your general ledger entries systematically until you find and correct the discrepancy.

Do I need accounting training to use trial balances?

Anyone can use trial balances without formal training. A trial balance follows a simple format: list your accounts, record debit and credit balances, and check that totals match. Accounting software makes this even easier by automating the calculations for you.
