Halloween might only come once a year, but for many small business owners, bookkeeping mistakes can haunt them all year long. From missing receipts to unbalanced accounts, these errors can creep up quietly and cause financial headaches when you least expect them.
At SMG, we’ve seen how small missteps can snowball into bigger problems. Here are the top 5 common bookkeeping mistakes to watch out for - and how to keep them from giving you a fright.
1. Ignoring Account Reconciliation
Avoiding reconciliation is like leaving your jack-o’-lantern lit overnight — things can rot before you even notice. When you skip it, small discrepancies grow into big problems.If your bank balance doesn’t match your books, you might have missing transactions, duplicate entries, or even unnoticed fraud. Reconciling monthly keeps your records clean and your confidence high.
Tip: Schedule time at the end of each month to review your bank and credit card statements. If you’re not sure what to look for, our team can help.
2. Mixing Business and Personal Expenses
This is one of the most common - and most chilling - mistakes we see. Using the same account or card for business and personal purchases may seem convenient, but it makes tracking expenses a nightmare and can cause problems during tax time.
Tip: Keep a dedicated business bank account and card. It keeps your records clear and protects your deductions if you’re ever audited.
3. Forgetting to Track Receipts
Lost receipts are like ghosts - they come back to haunt you when you least expect it. Without documentation, you risk missing out on legitimate business deductions or scrambling during tax preparation.
Tip: Snap photos of receipts and upload them to your accounting software in real time. Tools like QuickBooks and Xero make it simple to organize everything digitally.
4. Misclassifying Expenses
Putting expenses in the wrong category can distort your reports, affect your tax filings, and mislead your financial decisions. For example, labeling a personal expense as business-related can lead to compliance issues, while misclassifying business costs can cause missed deductions.
Tip: Take a few minutes each week to review your expense categories. Consistency now saves hours later.
5. Waiting Until Year-End to Clean Up Books
What is the scariest mistake of all? Waiting until December to do your bookkeeping. That’s when small errors pile up, missing receipts become impossible to find, and the rush to meet tax deadlines begins.
Tip: Build simple habits throughout the year - monthly reconciliations, weekly expense reviews, and quarterly financial check-ins. You’ll avoid the year-end panic and make tax season far less terrifying.
Don’t Let Your Books Turn Into a Horror Story
Bookkeeping doesn’t have to be spooky. With a little organization and the right support, you can keep your finances clear, compliant, and under control.
