Cleanup Bookkeeping

Learn It

Sometimes a bookkeeper inherits books that have not been properly maintained. Maybe the previous bookkeeper left. Maybe the owner was doing their own books. Maybe nobody was doing the books at all. The result is the same: the books are messy, incomplete, and not trustworthy.

Cleanup bookkeeping is the process of bringing those books back into order. It involves four steps:

The four steps of cleanup are:

1. Investigation. Understand the business. Gather statements, supporting documents, and records.
2. Reconstruction. Determine what the books should say based on the evidence.
3. Correction. Record supported adjustments to fix what is wrong.
4. Validation. Confirm the ending financial statements make sense.

The Cleanup Process

A bookkeeper does not start with journal entries. They start by understanding the business and the scope of the problem. Here is the order:

• Understand the business first. What does it do? How does it make money? What bank accounts and credit cards does it use?
• Establish cleanup scope. Which months or years need cleanup? What is already done?
• Protect existing records. Do not delete transactions. Reverse or adjust them. Keep an audit trail.
• Determine a reliable starting point. What is the last date the books were known to be correct? Often this is the last reconciled bank statement.
• Gather statements and support. Bank statements, credit card statements, loan statements, payroll reports, invoices, bills.
• Reconcile cash first. As we covered in Bank Reconciliation, cash is the most reliable starting point.
• Reconcile credit cards. See Credit Card Reconciliation.
• Review Accounts Receivable. Look for old invoices, negative balances, and unapplied payments. See Accounts Receivable.
• Review Accounts Payable. Look for old bills, duplicate entries, and vendor credits. See Accounts Payable.
• Review loans. Compare book balances to lender statements. See Loans and Debt.
• Review payroll liabilities and sales-tax liabilities.
• Review fixed assets. Make sure all assets are on the schedule and depreciation is recorded. See Fixed Assets and Depreciation.
• Review equity. Confirm owner contributions, draws, and distributions. See Owner Equity.
• Review clearing accounts. These should normally be zero. See Clearing Accounts and Undeposited Funds.
• Identify duplicates and omissions. See Bookkeeping Errors.
• Review P&L classification. Are expenses in the right accounts? Is revenue correct?
• Make supported corrections. Record adjustments with documentation.
• Document assumptions. If something cannot be fully resolved, document what was reviewed and what is assumed.
• Validate ending financial statements. Does the Balance Sheet balance? Does the P&L make sense? See P&L and Balance Sheet.
