At Protea Financial, we often meet business owners who are incredible at what they do, whether that is crafting an award-winning Cabernet, running a non-profit, or managing a bustling retail operation, but who view bookkeeping as a necessary evil. It is often treated as an afterthought, something to be rushed through late at night or handed off to a well-meaning relative.
However, bookkeeping is the diagnostic tool for your business’s health. When done correctly, it provides a roadmap for growth. When riddled with errors, it can lead to cash flow crises, tax audits, and missed opportunities.
We have seen the same patterns emerge time and again. The good news? These mistakes are entirely preventable. Here are the top bookkeeping mistakes we see, and actionable advice on how to avoid them.
1. Commingling Personal and Business Finances
This is the most common mistake, particularly for new small businesses. It happens innocently enough: you use the business card to buy lunch because you left your personal wallet in the car, or you pay a vendor from your personal checking account because the business funds were low.
Why it’s a problem: Commingling funds turns your books into a mess that takes hours to untangle. More importantly, it threatens your legal liability protection. If you treat your business bank account like a personal piggy bank, a court may decide to “pierce the corporate veil,” meaning your personal assets could be at risk in a lawsuit against your business.
How to avoid it: Maintain rigid discipline. Have separate bank and credit card accounts for the business. If you must put personal money into the business, record it formally as an “Owner’s Contribution.” If you take money out, record it as an “Owner’s Draw.” Never simply swipe and forget.
2. Treating Capital Assets as Immediate Expenses
When you buy a large piece of winery equipment, say, a new fermentation tank, a delivery van, or high-end office computers, it is tempting to simply categorize that cash outflow as an “Expense” to lower your profit (and taxes) for the year.
Why it’s a problem: Tax law distinguishes between expenses (consumables like paper, rent, and utilities) and assets (items with a useful life of more than one year). Expensing an asset immediately violates accounting principles and tax rules. It distorts your Profit & Loss statement, making it look like you lost money when you actually invested in value.
How to avoid it: Establish a capitalization threshold (e.g., $2,500). Any purchase over that amount that lasts longer than a year should be recorded as an Asset on the Balance Sheet and depreciated over time. Consult with your bookkeeper to set up proper depreciation schedules.
3. Relying Solely on the Bank Feed
Modern accounting software like QuickBooks Online has a wonderful feature that imports your bank transactions automatically. Many business owners believe that if the “bank feed” is empty, their bookkeeping is done.
Why it’s a problem: Bank feeds break. They disconnect. They duplicate transactions. Or, you might write a check that hasn’t cleared yet. If you rely only on the feed, you are looking at an incomplete picture. You might think you have $10,000 in the bank, but you actually have $5,000 because of uncleared checks.
How to avoid it: Perform a formal Bank Reconciliation every single month. This process compares your accounting ledger against the actual bank statement to ensure they match to the penny. It is the only way to catch bank errors, duplicate entries, or fraud.
4. Ignoring the Balance Sheet
Most business owners live and die by the Profit & Loss (P&L) statement. “Did we make money this month?” is the only question they ask.
Why it’s a problem: The P&L only tells half the story. It tells you about performance, but not about health. It doesn’t show you how much debt you owe (Liabilities), how much inventory you are sitting on (Assets), or how much customers owe you (Accounts Receivable). A business can show a profit on the P&L and still go bankrupt if it has no cash and massive debt.
How to avoid it: Review your Balance Sheet monthly alongside your P&L. Pay attention to your Accounts Receivable Aging (are customers paying you?) and your Inventory levels (are you tying up too much cash in stock?).
5. DIY Payroll
Payroll is deceptively complex. It is not just about writing checks; it involves withholding the correct federal and state taxes, paying the employer portion of FICA, filing quarterly reports (941s), and adhering to state labor laws regarding overtime and sick leave.
Why it’s a problem: The penalties for payroll errors are severe. The IRS does not look kindly on businesses that mishandle “trust fund taxes” (the money you withhold from employees). One missed deadline or calculation error can trigger fines that far exceed the cost of hiring a pro.
How to avoid it: Do not manually calculate payroll. Use a dedicated payroll provider (like Gusto or ADP) or hire a professional firm. The cost is negligible compared to the risk.
6. Misclassifying Employees as Contractors
It is cheaper and easier to hire a freelancer (1099 contractor) than an employee (W-2). You don’t have to pay payroll taxes or offer benefits. Because of this, many businesses try to squeeze employees into the “contractor” box.
Why it’s a problem: Government agencies are aggressively cracking down on this. If you control when, where, and how a person works, they are likely an employee. If you are caught misclassifying them, you will owe back taxes, unpaid overtime, and massive penalties.
How to avoid it: Learn the IRS common law rules regarding behavioral and financial control. When in doubt, err on the side of classifying workers as employees.
