What to Do If You’re Months (or Years) Behind on Your Bookkeeping

Let’s face it: life gets busy. You start a business to do what you love—not to spend hours buried in spreadsheets. If your bookkeeping has fallen months (or even years) behind, you’re not alone. And the good news? It’s absolutely fixable.

At DPP Bookkeeping, LLC, we help small business owners just like you get caught up, cleaned up, and back on track. Here’s a step-by-step guide to help you move from financial chaos to clarity—without the stress.

Step 1: Take a Breath and Assess the Damage

First things first—don’t panic. Behind on your books? It happens.

Ask yourself:

  • How far behind are you? (3 months? 12 months? More?)

  • Are you missing bank statements, receipts, or invoices?

  • Have you filed taxes recently?

Tip: Make a quick list of accounts you use (checking, credit cards, loans, PayPal, etc.) and how far back the records go.

Step 2: Stop Mixing Personal and Business Finances

If you’re still using one bank account for everything, now is the time to separate it.

Why it matters:

  • Makes cleanup MUCH easier

  • Keeps your books accurate moving forward

Open a business bank account and commit to using it only for business transactions from here on out.

Step 3: Gather Your Financial Documents

You’ll need source data to recreate your books. Gather:

  • Bank and credit card statements (digital downloads work great)

  • Loan statements

  • Receipts (physical or digital)

  • Invoices and payment records

  • Any previous bookkeeping files or spreadsheets

Pro tip: Most banks let you download up to 18 months of statements. For older records, contact your bank directly.

Step 4: Choose a Bookkeeping System (or Bookkeeper)

Now’s the time to get serious about staying organized.

If you're DIYing:

  • Use QuickBooks Online (QBO) for automation and bank feeds

  • Set up your chart of accounts based on your industry

  • Import transactions one account at a time

If you're overwhelmed:

  • Hire a professional bookkeeper (like me!) to take over the heavy lifting

Why this matters: You’ll save hours of frustration and avoid common cleanup mistakes.

Step 5: Start with the Most Recent Year and Work Backward

It’s tempting to go all the way back to day one, but focus on what’s urgent first:

  • Start with the current or most recent tax year

  • Prioritize months where there were large transactions or major changes

  • Once you’re caught up to the present, go back further if needed

Step 6: Reconcile All Bank and Credit Card Accounts

This is where cleanup really happens:

  • Match every transaction in your books to your actual bank/credit card statements

  • Flag and fix duplicates or missing entries

  • Use reconciliation reports to ensure accuracy

Why it matters: Reconciliation ensures your books reflect real-world activity and prevents tax or cash flow errors.

Step 7: Run Key Financial Reports

Once your books are caught up and reconciled, generate your:

  • Profit & Loss Statement

  • Balance Sheet

  • Cash Flow Report

Why this matters: These reports help you (and your tax preparer) understand the financial health of your business and file taxes accurately.

Step 8: File Missing Taxes or Amend Past Returns (if needed)

If your bookkeeping has been out of date for more than a year, you may have missed a tax filing or underreported income.

Work with a CPA or tax professional to:

  • File back taxes

  • Amend past returns with corrected numbers

  • Minimize penalties or interest
