Preventing Accounting Errors IN your business

Avoid financial missteps and strengthen your business foundation with smarter accounting practices.

Running a small business requires wearing many hats from managing operations and leading a team to handling customer relationships and making strategic decisions. With so much on your plate, accounting often falls lower on the list of priorities. Yet, accurate financial management is one of the most critical elements of long-term success.

At Smith Schafer, we’ve worked with Minnesota businesses for more than 50 years, helping owners simplify their financial systems, strengthen compliance, and make confident decisions. Here are several common accounting mistakes we see and how you can avoid them.

Mixing Personal and Business Finances

When your business is new, it’s tempting to use the same bank account for both personal and business expenses. But this shortcut creates unnecessary complexity.

Using one account can lead to:

  • Confusion when separating transactions
  • Significant issues when filing taxes   
  • Missed tax deductions
  • Problems applying for business loan or line of credit

Establishing separate business accounts for checking, credit, and savings helps you maintain accurate records and simplifies tax preparation. It also presents a more professional and organized financial picture to lenders and investors.

Skipping Accounting Software

While spreadsheets may work initially, manual tracking can quickly become inefficient as your business grows. Modern accounting software provides automation, accuracy, and valuable insights into your financial health.

Choosing the right platform for your business, and setting it up correctly, is essential. Smith Schafer’s business consulting team can help you evaluate and implement accounting software that fits your goals and scales with your growth.

Not Tracking Business Costs Accurately

Inaccurate or incomplete financial records can lead to poor decision-making, cash flow challenges, and compliance risks. Every transaction matters from small vendor payments to client deposits.

Consistent recordkeeping gives you visibility into profitability, expense trends, and future needs. Whether you handle your books internally or work with an external partner, investing in accuracy will save you time and money.

Misclassifying Expenses

Proper expense classification is vital for accurate reporting and tax compliance. Misclassifications can lead to skewed financial statements or missed deductions.

Review your chart of accounts monthly to ensure accuracy and identify redundant or unnecessary categories. A CPA can help you set up a structure that fits your specific business model, improving both clarity and tax readiness.

Poor Cash Flow Management

Cash flow is the heartbeat of any business. Confusing revenue with cash on hand can create operational strain and limit flexibility.

To manage cash flow effectively:

  • Monitor incoming and outgoing payments regularly
  • Create cash flow forecasts
  • Build a reserve for unexpected expenses

If cash management feels overwhelming, our Outsourced CFO Services can help you stay on top of your finances and plan for the future.

Trying to Do Everything Yourself

Small business owners are resourceful but accounting requires precision, expertise, and time. Attempting to manage it all can lead to errors and burnout.

By outsourcing your accounting to trusted professionals, you gain more than accurate books. You gain a proactive partner who can help identify opportunities, avoid costly mistakes, and keep your business compliant.

That’s where Smith Schafer comes in. We provide scalable accounting and tax services tailored to businesses. Our team combines decades of experience with personalized guidance so you can focus on what matters most, running your business.
