Step 1: Lock Prior Periods
Before touching data, lock all closed months to prevent accidental edits. This preserves past tax filings and protects historical accuracy.
Step 2: Reconcile All Bank and Credit Card Accounts
Start with current statements, then move backward. Each reconciliation should bring your ending balance in QuickBooks in line with the bank. Fix missing, duplicate, or uncleared transactions as you go.
Step 3: Review the Chart of Accounts
Years of ad-hoc entries can create redundant or misnamed accounts.
- Merge similar categories (for example, “Meals” and “Meals & Entertainment”).
- Delete unused accounts after confirming no active balances.
- Align categories with your CPA’s tax mapping.
Step 4: Clean Up Undeposited Funds
Undeposited funds are one of the most common QuickBooks errors.
- Match all received payments to deposits.
- Clear duplicates and ensure each deposit equals the bank record.
Step 5: Correct Opening Balances
Incorrect opening balances create reconciliation headaches. Compare QuickBooks starting balances with your earliest bank statement and adjust once, not month by month.
Step 6: Check Accounts Receivable and Payable Aging
Run aging reports to confirm no old or duplicate entries remain. Write off or correct balances older than 90 days if they are already settled.
Step 7: Verify Reports and Lock the File
After cleanup, generate a fresh Profit & Loss and Balance Sheet. Confirm totals match your bank, credit cards, and tax filings. Then lock the period again.
Optional: Document the Cleanup Process
Record what was changed, why, and by whom. This creates transparency for your CPA and prevents future confusion.
