What is an aged trial balance?

An aged trial balance combines a trial balance (a listing of all account balances) with aging analysis for accounts receivable and payable, showing both the total balances and their distribution across time buckets. For professional service firms, the aged trial balance provides a comprehensive view of financial position with collection and payment insights in a single report.

Key characteristics

• Combines the trial balance with AR and AP aging

• Shows all account balances in one report

• Includes time bucket distribution for receivables and payables

• Used for the month-end review and audit

• Highlights potential collection issues

• Foundation for financial statement preparation

Why it matters for professional service firms

The aged trial balance combines balance verification with collection insights. Rather than reviewing separate reports, management can see both the overall financial position and the aging status. Professional service firms should review the aged trial balance monthly as part of the close process, investigating unusual balances, verifying aging accuracy, and identifying accounts requiring attention.

Real-world example

Tom's firm reviewed the trial balance and aging separately, sometimes missing connections between them. Implementing aged trial balance: single report showing all account balances plus AR aging (current $125K, 1 to 30 days $82K, 31 to 60 days $45K, 61 to 90 days $18K, over 90 days $12K) and AP aging (current $38K, 1 to 30 days $22K, over 30 days $5K). Monthly review revealed: one large AR in the 61-90 bucket was from a client with credit issues (flagged for collection focus), and one AP over 30 was a disputed invoice (resolution needed). The combined view surfaced issues that separate reports missed
