Frequently Asked Questions


  • 1. Is QuickBooks Online the only software that you work with?

    Being a Certified QuickBooks Online ProAdvisor means I have a level of familiarity and expertise with QBO. However, while I am most comfortable with that platform, I do not work exclusively with it and will work with other software.

  • 2. What's the difference between a bookkeeper and a CPA?

    A bookkeeper records and classifies daily financial transactions (such as payroll, sales/service income, and bill payments), reconciles accounts against bank/credit card statements, and generates financial statements for management to review. A bookkeeper can also help with certain accounting advisory services (see my services page). A CPA is more than capable of this, but many CPAs typically specialize in the preparation and filing of taxes and can also perform a company audit. Both are important to running a business/organization. 

  • 3. Do you do taxes?

    No, taxes make my stomach hurt. However, I am happy to refer you to a good tax person.

  • 4. Do I need a bookkeeper and a tax preparer?

    This is a question every business owner should decide for themselves. It is my recommendation that you have someone (you/me/someone else) managing your bookkeeping and then a completely separate person preparing/filing the taxes. It's good to have another set of eyes on your finances on a regular basis, and many tax preparers focus more on tax work than on the monthly bookkeeping side.

Launching a nonprofit is a rewarding and inspiring endeavor, but one of the most overlooked and often misunderstood aspects of early success is financial management. A solid financial foundation doesn’t just support operations, it builds trust with donors, enables strategic growth, and ensures long-term sustainability. If you're a new nonprofit founder, here are essential tips for setting up proper bookkeeping systems, managing your cash flow, and preparing for the future. 1. Start with a Robust Bookkeeping System Before the first donation hits your bank account, you need a reliable bookkeeping system. It doesn’t have to be overly complex, but it must be accurate, organized, and scalable. Here are some things to consider when getting started. First, c hoose the right software. Options like QuickBooks for Nonprofits, Wave, or Aplos are tailored to nonprofit needs and offer features like fund tracking and donation reporting. Second, u se the accrual method. While cash accounting might seem simpler, accrual accounting gives a clearer picture of your financial health and is generally required for grant reporting and audits. Third, s et up a chart of accounts. Create clear categories for revenue (grants, donations, program income) and expenses (program services, administrative costs, fundraising). Keep it simple but comprehensive. Finally, t rack restricted vs. unrestricted funds. This is critical in nonprofits. Ensure your bookkeeping system can track how and when restricted funds are used. 2. Structure Your Accounts Wisely Structuring your financial accounts correctly from the beginning will save you major headaches down the line. The first step in doing this is to open a dedicated nonprofit bank account. Never mix personal and organizational finances. This ensures transparency and is necessary for 501(c)(3) compliance . The next step is to separate operating and reserve funds. Create distinct accounts for day-to-day expenses and long-term reserves or restricted grants. Lastly, implement internal controls. Even in a small team, assign roles to separate financial duties (e.g., one person enters expenses, another approves payments). This helps prevent errors and fraud. 3. Keep a Close Eye on Cash Flow Nonprofits can be especially vulnerable to cash flow challenges due to grant cycles, donor seasonality, and reimbursement delays. To meet these challenges, first create a cash flow forecast. Project your inflows and outflows monthly. Update it regularly to anticipate and manage shortfalls. Second, invoice promptly and follow up. If you’re billing for services or waiting on pledged donations, establish a system to track and follow up consistently. Third, build a 3–6 month operating reserve. It won’t happen overnight, but aim to set aside reserves that can cover operating expenses during lean times. 4. Plan for Growth, But Stay Grounded As your nonprofit grows, your financial needs and reporting requirements will evolve. When starting out, document financial policies and procedures. As soon as you can, put key practices in writing. This creates consistency and is essential for audits or grant applications. Next, hire or contract a bookkeeper or accountant. Even if you’re bootstrapping, working with a financial professional can help ensure compliance and accuracy. Finally, use your financial data strategically. Regularly review financial reports with your board and leadership team to inform decisions and align spending with mission goals. Final Thoughts Starting strong with your nonprofit’s finances isn’t just about compliance; it’s about stewardship. Donors, grantors, and beneficiaries alike depend on your organization’s ability to use resources wisely and transparently. By investing time and care into your financial setup early on, you're not just tracking dollars, you're building trust, sustainability, and impact.

Managing your business or personal finances requires more than just tracking your expenses or generating profit and loss statements. One of the most critical yet often overlooked aspects of bookkeeping is bank reconciliation. This simple yet powerful process can help you catch errors, prevent fraud, and ensure your records accurately reflect your financial reality. What Is Bank Reconciliation? Bank reconciliation is the process of comparing your internal financial records, such as those in your accounting software or ledger, to your bank statements. The goal is to ensure that every transaction listed by your bank matches what you've recorded. If discrepancies arise, you investigate and resolve them. Why Bank Reconciliation Matters There are many reasons bank reconciliation matters. First, mistakes happen. Whether it's a double entry, a missed transaction, or a typo, bank reconciliation helps you identify and fix these issues before they snowball into larger problems. Second, it allows you to detect fraud and unauthorized transactions. Regular reconciliation allows you to spot any unusual or unauthorized activity quickly. If your account was accessed fraudulently or if a vendor overcharged you, you'll catch it much faster by reconciling your statements regularly. Third, it ensures accurate financial reporting. Your financial statements are only as accurate as the data behind them. Reconciling ensures your books reflect the true state of your finances, essential for decision-making, tax filing, and securing loans or investments. Finally, it improves cash flow management. Knowing exactly how much cash you have on hand is vital for meeting obligations, planning future expenses, and avoiding overdrafts or bounced payments. How Often Should You Reconcile? Monthly is the standard recommendation, especially for small businesses and individuals. Most banks issue monthly statements, which provides a natural cadence for reconciliation. However, depending on your transaction volume, you might benefit from more frequent checks. These more frequent checks include (a) weekly or biweekly, which is ideal for businesses with high transaction volumes, such as retail or e-commerce or (b) daily, which is useful in high-risk environments or where fraud prevention is critical. This is more common in financial institutions or businesses dealing with large sums of money. In short, frequent reconciliation minimizes errors and helps you keep a close eye on cash flow. Tips for Effective Bank Reconciliation Use Accounting Software: Tools like QuickBooks , Xero, Wave, or FreshBooks can automate parts of the reconciliation process and reduce manual errors. Stay Organized: Keep digital or physical copies of invoices, receipts, and payment confirmations for easy reference. Assign Responsibility: Make reconciliation a routine task, assigned to a specific team member or accountant, to ensure consistency and accountability. Final Thoughts Bank reconciliation may not be the most glamorous aspect of financial management, but it's one of the most essential. Think of it as a regular health checkup for your finances. The more consistent you are, the less likely you'll face unpleasant surprises down the road. By reconciling your accounts regularly, ideally monthly, or more frequently as needed, you gain greater control, accuracy, and confidence in your financial decision-making. It's a small investment of time that pays significant dividends in peace of mind and financial integrity.

In the world of nonprofit organizations, trust and transparency are everything. Whether you're applying for grants, reporting to your board, or communicating with donors, clear and accurate financial reporting plays a critical role. Yet for many nonprofits, creating and maintaining these reports can be time-consuming and overwhelming. The good news? Financial reporting doesn’t have to be complicated. With the right tools and strategies, your organization can streamline the process and ensure that your reports are both simple and effective. Here’s how: 1. Know Your Audience: Why Financial Reports Matter Before diving into how to create reports, it’s important to understand why they matter—and to whom. Donors want to see that their contributions are being used responsibly and effectively. Board members need a clear picture of the organization’s financial health to make informed decisions. Grantmakers often require financial documentation as part of their funding criteria. The public expects transparency, especially for organizations that rely on community support. Well prepared financial reports help build credibility and demonstrate accountability, which are key to your nonprofit’s growth and sustainability. 2. Focus on Key Financial Statements Keep it simple by focusing on the most relevant reports. The three main financial statements for nonprofits include: Statement of Financial Position (Balance Sheet): Shows what your organization owns (assets), owes (liabilities), and net assets. Statement of Activities (Income Statement): Displays revenue and expenses over a specific period. Statement of Cash Flows: Tracks the flow of cash in and out of the organization. Start with these core documents, and avoid overloading reports with excessive detail unless specifically required. 3. Use Consistent, Clear Formatting Consistency and clarity go a long way. Standardize your report layouts, use clean tables or charts where appropriate, and avoid overly technical language. Visuals like pie charts or bar graphs can help non-financial readers quickly grasp key points. 4. Leverage Software to Automate and Simplify Cloud-based accounting tools such as QuickBooks Online, Xero, or other nonprofit-focused platforms can help automate report generation. These tools allow you to: Set up customized reports Track restricted and unrestricted funds Generate real-time dashboards for board meetings Ensure accuracy through automation and built-in checks Using technology not only saves time—it also reduces the risk of manual errors. 5. Set a Regular Reporting Schedule Create a routine reporting schedule (monthly, quarterly, annually) and stick to it. This builds a rhythm that board members and stakeholders can rely on. It also ensures issues are caught and addressed early, rather than becoming larger problems later on. 6. Train Your Team (and Yourself) Even the best systems won’t help if the people using them aren’t confident. Offer training for staff or volunteers who are involved in financial tracking and reporting. If you're handling the books yourself, consider partnering with a professional bookkeeper familiar with nonprofit compliance and reporting standards. In Summary: Streamlining financial reporting for your nonprofit doesn’t mean cutting corners—it means making the process more efficient, more understandable, and more useful. With a focus on simplicity, consistency, and the right tools, you’ll be better equipped to earn donor trust, support your board’s decision-making, and keep your organization financially transparent.

A monthly budget is written on a piece of paper.
By Tim Prewette April 25, 2025
Creating a budget for your business might sound intimidating, but it doesn't have to be. A solid budget helps you plan for growth, avoid surprises, and feel more in control of your finances. Here's a quick-start guide just for you. What Is a Business Budget? A business budget is a monthly plan for your income and expenses. It helps you forecast revenue, control costs, and make confident financial decisions. Why Budgeting Matters: Keeps spending aligned with your goals Helps avoid cash flow issues Prepares you for slow months or surprise expenses Supports smarter business decisions Types of Expenses to Include: Fixed Costs : Rent, insurance, software subscriptions Variable Costs : Supplies, shipping, hourly labor Periodic Costs : Taxes, license renewals, annual fees Sample Budget Layout : Category Projected Amount Actual Amount Revenue $8,000 $7,500 Fixed Expenses $2,000 $2,000 Variable Expenses $1,500 $1,650 Periodic Savings $500 $500 Emergency Buffer $300 $300 Net Profit $3,700 $3,050 Budgeting Do's and Don'ts DO: Review your budget monthly Include a small buffer for the unexpected Track every transaction, no matter how small  DON'T : Rely solely on your bank balance. Your bank balance only tells part of the story—it’s a snapshot, not the full picture. Guess at expenses. Use real data when possible. Set it and forget it. Your budget should evolve with your business! Don’t confuse profit with cash flow . Just because your Profit and Loss report shows a profit doesn’t mean you have cash in the bank. Monitor both separately. Don’t ignore small, recurring expenses. Subscriptions, software, or transaction fees may seem minor but can add up significantly over time if left unchecked.

Cash flow is the lifeblood of any business, and managing it effectively can be the difference between simply surviving and truly thriving. For growing businesses, the stakes are even higher. As operations expand, so do expenses, and without careful planning, even a profitable business can face cash shortages. Thankfully, there are practical, actionable strategies you can implement to keep your cash flow healthy and predictable. One of the simplest and most effective ways to improve cash flow is to accelerate incoming payments. Encourage prompt payment by setting clear terms, offering early payment incentives, and using invoicing software that sends automatic reminders. On the flip side, consider negotiating extended payment terms with vendors to give yourself a bit more breathing room. For example, a service-based business might offer a 2% discount for invoices paid within 10 days to encourage faster turnaround. Another powerful tool in your cash flow arsenal is creating and maintaining a rolling cash flow forecast. This means projecting your income and expenses 30, 60, or even 90 days ahead, and updating it regularly. It helps you anticipate shortfalls before they become urgent and gives you the opportunity to adjust spending or seek additional funds in a timely way. This kind of forecasting can be as simple as a spreadsheet, or you can use tools like Float, Pulse, or even integrations within your accounting software. Reducing overhead costs is also key. As your business grows, it can be easy for recurring expenses to quietly creep upward. Regularly review subscriptions, vendor contracts, and utility bills to ensure you’re not overpaying or paying for services you no longer use. Even small cuts can free up significant cash over time. For example, switching to a co-working space instead of a private office, or bundling services with a single vendor, might reduce costs without sacrificing quality. Inventory management plays a big role in cash flow, especially for product-based businesses. Holding too much inventory ties up cash that could be used elsewhere. Consider adopting a just-in-time approach or using software that helps optimize inventory levels based on real-time demand. A local boutique, for instance, might track seasonal trends to reduce over-ordering and ensure they’re not stuck with unsold stock. Finally, don’t overlook the value of working with a professional. A bookkeeper or financial advisor can help you track cash flow accurately, spot trends, and identify opportunities for improvement. They can also help you establish systems that reduce the manual work involved in financial tracking, freeing up your time for higher-level planning. With the right systems and support in place, you can not only stay ahead of your cash needs but build a business that grows sustainably and confidently.

As a small business owner, keeping a close eye on your finances is essential to your success. While day-to-day financial management like tracking expenses and income is important, it’s equally critical to have a clear understanding of where your business is heading financially. This is where financial forecasting comes in. In this post, we’ll explore what financial forecasting is, why it’s crucial for your small business, and how to create an effective forecast that will help you plan for the future. What is Financial Forecasting? At its core, financial forecasting is the process of estimating your business’s future financial outcomes based on historical data, current trends, and market conditions. Essentially, it's a prediction of how much revenue you expect to earn, what your expenses might look like, and what your profits (or losses) could be during a specific period in the future. Forecasting isn’t about making perfect predictions—it’s about making educated guesses based on the best available information. A solid financial forecast helps guide business decisions, manage cash flow, and avoid unexpected surprises. Types of Financial Forecasts There are two main types of financial forecasts small businesses typically use: Short-Term Financial Forecasting Timeframe: Typically covers periods of up to one year. Purpose: Focuses on immediate cash flow , upcoming expenses, and working capital needs. It helps ensure that you have enough funds to cover your day-to-day operations and avoid cash flow problems.  Long-Term Financial Forecasting Timeframe: Usually spans one to five years or more. Purpose: Provides a broader view of your business’s financial future, helping with strategic planning, growth targets, and investment decisions. This forecast is often used to inform business expansion plans and funding needs. Why Does Financial Forecasting Matter? Financial forecasting is vital for several reasons. Here’s why it should be a priority for your business: 1. Helps Manage Cash Flow Cash flow is the lifeblood of any business. If you’re spending more money than you’re making or if you have unpredictable income streams, forecasting helps you anticipate periods of cash shortfall and plan ahead to avoid financial stress. A good forecast lets you know when to expect large expenses or drops in revenue, giving you time to adjust. 2. Guides Decision-Making Accurate financial forecasting provides critical data to inform your business decisions. Whether you’re deciding when to hire new employees, invest in new technology, or explore new markets, having a financial forecast helps ensure that your decisions align with your business’s capacity and financial reality. 3. Improves Financial Planning A forecast acts as a roadmap for your business. By projecting future revenue, costs, and profit margins, you can identify potential issues and opportunities before they happen. This insight allows you to set realistic budgets, identify areas to cut costs, and spot trends that could drive growth. 4. Helps Secure Financing Whether you’re seeking a loan or looking to attract investors, potential lenders or investors want to know that your business is financially sound and has a plan for growth. A solid financial forecast demonstrates that you have a clear understanding of your business’s financial position and future potential. 5. Mitigates Risk Running a business always involves some level of risk, but forecasting allows you to anticipate and manage those risks. For instance, if you foresee a dip in revenue, you can adjust your expenses accordingly. Similarly, if you expect increased demand, you can plan to increase inventory or hire additional staff. 6. Increases Business Valuation Financial forecasting can give you a clearer picture of your company’s financial health , which is crucial if you're planning to sell your business or bring in investors. A strong, well-supported financial forecast increases confidence in your business’s value and future potential. How to Create a Financial Forecast for Your Small Business Creating a financial forecast involves gathering historical financial data, making assumptions about future performance, and projecting key financial statements. Here's how to get started: Step 1: Gather Historical Financial Data The first step in any forecast is reviewing your past financial performance . Look at your income statements, balance sheets, and cash flow statements from previous periods. This data will give you a baseline for future projections. Key metrics to gather: Revenue (sales and other income) Operating expenses (cost of goods sold, rent, utilities, etc.) Gross profit margin Net income Cash flow Step 2: Identify Key Assumptions Your forecast is based on certain assumptions about the future. These could include expected sales growth , planned price changes, or seasonal demand fluctuations. You'll need to make educated assumptions about these factors based on market research, industry trends, and your business’s historical performance. Common assumptions to consider: Sales growth rate Customer acquisition cost Pricing strategies Expense trends (e.g., inflation, salary increases) Step 3: Project Revenue and Expenses Revenue: Start by projecting how much revenue you expect to generate during the forecast period. Consider factors like seasonality, marketing campaigns, new product launches, or changes in your market. Expenses: Next, estimate your business expenses, such as rent, payroll, utilities, inventory costs, and marketing. Be sure to factor in both fixed and variable costs. Step 4: Prepare Financial Statements Based on your projections, create the following key financial statements: Income Statement : This shows projected revenue, expenses, and profits for the forecast period. Cash Flow Statement : This outlines the expected inflows and outflows of cash, helping you plan for periods when cash might be tight. Balance Sheet : This gives a snapshot of your business’s assets, liabilities, and equity, showing the financial position of your company. Step 5: Monitor and Adjust A forecast is not a set-it-and-forget-it tool. You should monitor your actual performance regularly and adjust your forecast as needed. If you experience unexpected changes, like a sales slump or unexpected expense, update your forecast to reflect those shifts. Tools to Help with Financial Forecasting Many small businesses use accounting software to help with financial forecasting. Some popular tools include: QuickBooks: Offers budgeting and forecasting tools to help you predict cash flow and expenses. Xero: Provides easy-to-use forecasting tools for small businesses. Excel or Google Sheets: A manual, but customizable way to create financial forecasts from scratch. Conclusion Financial forecasting is an essential tool for every small business . It gives you a roadmap for managing cash flow, making informed decisions, and positioning your business for growth. By understanding your financial future, you’ll be better equipped to handle challenges, seize opportunities, and keep your business on track. Remember, forecasting is an ongoing process, so regularly update your forecast to stay aligned with your business’s changing needs. With careful forecasting, you’ll not only protect your business’s financial health but also gain valuable insights that drive long-term success.
