Catching Up on Bookkeeping: A 30-Day Plan for Business Owners

Why Bookkeeping Catch-Up Matters

Falling behind on your bookkeeping happens more often than you think—especially for small business owners juggling sales, staffing, and operations. Whether you’re a few months or a few years behind, cleaning up your books is critical for tax compliance, loan applications, financial decision-making, and peace of mind.

The good news? With a structured plan, you can get your books current in just 30 days. Here’s a step-by-step guide to help you catch up—efficiently and correctly.


Week 1: Assess the Damage and Organize Your Files

Goals:

  • Determine how far behind you are (months or years)
  • Identify what financial records are missing
  • Set up systems to organize documents going forward

Tasks:

  • List each month or year that is incomplete or unfiled
  • Locate all bank and credit card statements, loan records, and receipts
  • Reconnect or set up your bookkeeping software (QuickBooks, Xero, etc.)
  • Create folders (physical or digital) by month and account

Tip: If you have no software set up yet, consider QuickBooks Online and consult with a professional to configure your chart of accounts properly from the beginning.


Week 2: Reconcile Your Bank and Credit Card Accounts

Goals:

  • Ensure every transaction is recorded and matched
  • Catch and fix errors, duplicates, and missed entries

Tasks:

  • Download transaction history from all business accounts
  • Reconcile each account month by month
  • Identify personal transactions that need to be reclassified
  • Create journal entries for any adjustments

Common Issues:

  • Transfers between accounts recorded as income or expense
  • Duplicate entries from manually entered and downloaded transactions
  • Loan payments recorded as full expense instead of principal/interest split

Week 3: Categorize Expenses and Clean Up Accounts

Goals:

  • Accurately assign all income and expenses to appropriate accounts
  • Ensure your reports reflect true business activity

Tasks:

  • Use standardized categories aligned with your industry and tax return
  • Categorize recurring expenses with rules (rent, software, subscriptions)
  • Record fixed assets and capitalize where necessary
  • Split personal and business expenses if you commingled funds
  • Clean up Accounts Receivable and Accounts Payable aging reports

Watch Out For:

  • Recording owner draws or contributions as income or expense
  • Deducting non-deductible expenses like fines, penalties, or personal meals
  • Leaving uncategorized or “ask my accountant” transactions unresolved

Week 4: Generate and Review Financial Reports

Goals:

  • Ensure your Profit & Loss and Balance Sheet are accurate
  • Prepare for tax filing or strategic planning

Tasks:

  • Run monthly Profit & Loss reports for each period
  • Review your Balance Sheet to ensure accuracy in asset and liability accounts
  • Check for negative balances in accounts that shouldn’t be negative
  • Identify large or unusual transactions and verify accuracy
  • Review Owner’s Equity section for accuracy in capital accounts and distributions

If You’re Filing Taxes:

  • Confirm that all income and expenses align with your prior tax returns (if applicable)
  • Prepare a year-end P&L and Balance Sheet for your CPA or Accountant
  • If you have payroll, confirm W-2s and 941s reconcile with year-end numbers

Bonus Tip: Set Up Systems to Stay Current Going Forward

Once your books are caught up, the key is to stay on top of them. Here’s how:

  • Schedule weekly bookkeeping sessions (30–60 minutes)
  • Automate transaction downloads and reconciliation in your accounting software
  • Create monthly checklists for reconciliations, categorization, and reporting
  • Consider outsourcing monthly bookkeeping if time is limited

When to Call in Professional Help

If your records are more than a year behind, you’ve received IRS notices, or your business is growing faster than you can keep up, working with a bookkeeping professional is the fastest, most accurate solution. They can:

  • Rebuild prior year books
  • Reconcile complex accounts
  • Prepare financials for back tax returns or audits
  • Set you up for future success with accurate, timely data
