Accounting for small business is one of the first things new entrepreneurs need to get right, yet it is often the last thing they prioritize. Carol Treska, CFO Services Manager at Pease Bell CPAs, has spent years helping small business clients across industries avoid the financial missteps that stall growth. Her advice, originally shared at the Female Entrepreneur Summit (FES) in Northeast Ohio, offers a practical roadmap for any founder setting up shop.
The FES was created to support the underserved population of female business owners in Ohio and beyond. Now a well-established event, it brings together hundreds of female entrepreneurs to learn from nationally recognized presenters and panelists. Treska joined attorneys and a member of the Small Business Association on a panel focused on one question: how do you avoid the most common mistakes when starting a business?
The answer starts with two decisions that affect nearly everything else: your business entity structure and your accounting setup.
Why your business entity structure matters more than you think
Choosing the right business entity structure is not just a legal formality. It directly determines how much you pay in taxes, how you handle liability, and how you can eventually sell or transfer the business. Many first-time entrepreneurs default to a sole proprietorship because it is the easiest to set up, but that simplicity comes at a cost.
A sole proprietorship offers no separation between personal and business assets. If the business is sued or accumulates debt, personal savings, property, and other assets are exposed. Beyond liability, sole proprietors pay self-employment tax on all net earnings, which can add up to a 15.3% surcharge on top of income tax. The IRS Self-Employed Individuals Tax Center lays out these obligations in detail.
An LLC, or limited liability company, creates a legal barrier between the owner’s personal assets and the business. It also offers flexibility in how income is taxed. A single-member LLC is taxed as a sole proprietorship by default, but the owner can elect to be taxed as an S corporation, a move that can meaningfully reduce self-employment tax liability once the business reaches a certain income threshold. The Small Business Administration’s guide to choosing a business structure is a useful starting point before you commit.
LLC vs S corp: which entity is right for your startup?
The LLC vs S corp decision is one of the most searched business formation questions for good reason. The two structures are not mutually exclusive. An LLC is a legal designation that governs liability protection and business operations. An S corp is a tax election that governs how the IRS treats business income. You can form an LLC and then elect S corp tax status, getting the liability protection of one with the tax treatment of the other.
The key benefit of an S corp election is the ability to split income into salary and distributions. Only salary is subject to payroll taxes, while distributions are not. For a business owner earning $120,000, paying herself a reasonable salary of $70,000 and taking $50,000 in distributions could save several thousand dollars in self-employment taxes per year. The IRS expects S corp shareholder-employees to take reasonable compensation before distributions, and its S corporations page covers the election requirements and links to its guidance on this standard.
However, an S corp election is not free. It requires the owner to run payroll, file additional tax returns, and maintain corporate formalities. For very early-stage businesses or those with low and unpredictable income, the administrative burden may outweigh the savings. A CPA can model the numbers for your specific situation and tell you exactly when the switch makes financial sense, which is one reason proactive tax advisory services pay for themselves.
How to set up accounting for a small business from day one
Setting up accounting for a small business correctly from the start prevents costly cleanup later. Treska emphasizes that the accounting system is not just a way to track money. It is the foundation for tax compliance, cash flow management, and informed decision-making.
Start by opening a dedicated business bank account. Co-mingling personal and business funds is one of the most common mistakes new entrepreneurs make, and it can jeopardize the liability protection that your LLC or corporation provides. Courts can “pierce the corporate veil” if they determine that the business and personal finances were not kept sufficiently separate.
Next, choose an accounting method. Cash-basis accounting records revenue when you receive payment and expenses when you pay them. Accrual-basis accounting records revenue when it is earned and expenses when they are incurred, regardless of when money changes hands. Most small businesses start with cash-basis because it is simpler, but businesses that carry inventory or invoice clients with payment terms may need accrual-basis to get an accurate financial picture.
Finally, select accounting software that matches your business complexity. Cloud-based platforms allow real-time access to financial data and simplify collaboration with a CPA or bookkeeper. Whatever tool you choose, commit to recording transactions consistently, weekly at minimum. Businesses that let bookkeeping slide for months end up paying their accountant significantly more to reconstruct records at tax time. Outsourced client accounting services can carry this load for owners who would rather focus on growth.
Common accounting mistakes to avoid when starting a business
Mistakes to avoid when starting a business are not limited to choosing the wrong entity. Many entrepreneurs make errors in their day-to-day financial operations that compound over time.
Failing to track expenses from day one. Every business expense, from domain registrations to coffee meetings with potential clients, is potentially deductible. Without a system to capture these costs in real time, deductions get lost and tax bills run higher than necessary.
Not setting aside money for taxes. Unlike employees who have taxes withheld from every paycheck, business owners must estimate and pay taxes quarterly. Entrepreneurs who spend everything they earn often face a painful surprise when quarterly or annual tax payments come due. A general rule is to set aside 25-30% of net income for taxes, and the IRS estimated taxes guidance explains the payment schedule, though your CPA can refine the estimate for your situation.
Skipping the CPA conversation until tax season. The most expensive time to consult a CPA is after the year is over and decisions have already been made. Proactive tax planning, ideally starting before the business is even formed, can save thousands of dollars. Entity selection, retirement account setup, and estimated tax payments all benefit from professional guidance early on.
Treating accounting as optional overhead. Solid financial records are not just for the IRS. They tell you which products or services are profitable, whether you can afford to hire, and when you need to raise prices. Entrepreneurs who treat accounting as a necessary evil miss the strategic value hiding in their own numbers.
Why female entrepreneurs benefit from CPA guidance early
Female entrepreneurs face a unique set of challenges when launching and scaling a business. Access to capital is one of the most cited barriers. Women-owned businesses receive a disproportionately small share of venture capital and small business lending. Clean, professional financial records can make the difference when applying for a loan or pitching to investors.
Beyond funding, a CPA who understands the specific needs of female-owned businesses can help with programs and certifications designed to level the playing field. The Women’s Business Enterprise National Council (WBENC) certification, for example, can open doors to corporate and government contracts. But the certification process requires detailed financial documentation that a CPA can help prepare.
Events like the Female Entrepreneur Summit play an important role in connecting women founders with this kind of expert guidance. By bringing CPAs, attorneys, and business advisors together with entrepreneurs at every stage, these summits provide the education and networking that many business owners would not otherwise access.
Setting your business up for long-term financial health
Getting your accounting for small business right is not a one-time task. As the business grows, the financial infrastructure needs to grow with it. What works for a solo freelancer billing $50,000 a year will not work for a company with employees, inventory, and six-figure revenue.
Plan for regular financial reviews, quarterly at minimum. These reviews should cover cash flow trends, profit margins by service or product, outstanding receivables, and tax projections. A CPA can turn these reviews into actionable strategies rather than backward-looking reports.
Consider building a relationship with a CPA firm that offers CFO-level advisory services, not just tax preparation. Firms like Pease Bell provide a full range of accounting services and fractional CFO support that give growing businesses access to strategic financial guidance without the cost of a full-time hire. This kind of partnership ensures that as your business evolves, your financial strategy evolves with it.
Frequently Asked Questions
What is the best business entity structure for tax advantages?
The best structure depends on your income level, growth plans, and tolerance for administrative complexity. An LLC with an S corp tax election often provides the strongest combination of liability protection and tax savings for small business owners earning above $40,000-$50,000 in net profit. Consult a CPA to model the numbers for your specific situation.
How do I set up accounting for a new small business?
Open a separate business bank account, choose between cash-basis and accrual-basis accounting, and select a cloud-based accounting platform. Record transactions at least weekly and keep all receipts. Hiring a bookkeeper or CPA from the start prevents costly catch-up work later.
What is the difference between an LLC and an S corp?
An LLC is a legal entity type that provides liability protection. An S corp is a tax classification that determines how the IRS taxes your business income. You can form an LLC and then elect S corp tax treatment to get the benefits of both: liability protection plus potential payroll tax savings.
What are the most common accounting mistakes new business owners make?
The most common mistakes include co-mingling personal and business funds, failing to track expenses from day one, not setting aside money for quarterly taxes, and waiting until tax season to consult a CPA. Each of these errors can cost hundreds or thousands of dollars to correct.
Why should female entrepreneurs work with a CPA?
Female entrepreneurs benefit from CPA guidance because clean financial records improve access to lending and investment, areas where women-owned businesses are historically underserved. A CPA can also help with certifications like WBENC that open doors to corporate and government contracts.
When should a small business switch from an LLC to an S corp?
Most CPAs recommend evaluating the S corp election once your business consistently earns $40,000-$50,000 or more in annual net profit. Below that threshold, the payroll tax savings typically do not outweigh the added administrative costs. Your CPA can run the specific calculation for your income level.
