How New Business Owners Can Use P&L, Budgeting, and Forecasting to Improve Profitability

Entrepreneurs should view financial reports as decision-making tools, rather than burdensome paperwork. A P&L reveals whether growth is profitable, budgeting drives disciplined resource allocation, and forecasting turns data into strategy. Together, they move you from reacting to results to actively managing your business’s future.

Why Financial Management Matters

As a small business owner, you already juggle sales, operations, marketing, and customer service. But when it comes time to apply for a loan, talk with investors, or simply explain how your business is performing, you’ll be expected to speak knowledgeably about your financials. That confidence comes from knowing how to read and use your reports.

Entrepreneurs who review their profit and loss (P&L) statement and participate in regular budgeting and forecasting can identify trends before they become problems and make proactive decisions about growth and cost control. Those who don’t understand their financial reports risk being caught off guard by cash shortages, runaway expenses, or missed growth opportunities.

At Wendroff & Associates, we work with hundreds of small business owners to help them prepare and learn how to interpret their financial reports. This article serves as a starting point for understanding your P&L, utilizing budgeting and forecasting effectively, and gaining insights to help you run a stronger, more profitable company.

What Is a Profit & Loss (P&L) Statement?

A profit and loss statement (also called an income statement) summarizes your revenue, expenses, and profit (or loss) over a specific period of time. It shows:

• Revenue: How much your business earned from sales or services.
• Cost of Goods Sold (COGS): The direct costs associated with producing your product or service.
• Gross Profit: Revenue minus COGS — an indicator of efficiency.
• Operating Expenses: Overhead, such as payroll, rent, marketing, and administrative costs.
• Net Income (or Loss): The bottom line — profitability after all expenses.

Think of your P&L as a report card for your business’s financial health. Reviewing it regularly helps you identify where profits are coming from, whether costs are under control, and whether the business is sustainable.

Wendroff Pro Tip: Even profitable businesses can fail if they don’t manage cash flow. Pair your P&L review with a look at your cash position to ensure you can fund operations while waiting for receivables to come in.

Why Your P&L Matters

When new business owners review their P&L, three questions should be top of mind:

1. Where are my profits coming from? Break down revenue by product, service, or location to see which parts of your business are performing best.
   
2. Are my expenses in line? Compare your current P&L with previous periods. If revenue grows 15% but expenses grow 40%, that’s a red flag.
   
3. Am I actually profitable? The bottom line tells you if you’re making money, breaking even, or losing money. Even unprofitable businesses can learn from their P&L to make adjustments that put them back on track.

How Should Business Owners Review a P&L Statement?

When you look at your P&L (we recommend doing this monthly), follow these steps:

• Start with Revenue – Look at trends over time. Is revenue increasing, flat, or inconsistent? Calculate net sales (gross sales minus returns, discounts, and allowances).
  
• Check Gross Profit – Formula: Revenue – COGS = Gross Profit. This shows how efficiently you’re producing and selling your product or service.
  
• Review Operating Expenses – Fixed (rent, insurance), variable (supplies, payroll), and non-cash (depreciation). Look for categories that have crept up unexpectedly.
  
• Examine Net Profit (Bottom Line) – Formula: Gross Profit – Operating Expenses = Net Operating Profit. After accounting for taxes and other income/expenses, this shows your true profitability.
  
• Compare Period to Period – Spotting patterns is more important than one-time numbers.
  
• Ask the Right Questions
  • Am I pricing my products/services correctly?
  • Are certain expenses growing too quickly?
  • Do I need to reinvest profits into growth, or focus on controlling costs?
    

Wendroff Pro Tip: Many new owners only look at their P&L at tax time. A monthly (or even quarterly) review is critical to staying ahead of issues.

Budgeting & Forecasting: The Next Step After Reviewing Your P&L

Your P&L shows you what has already happened. Budgeting and forecasting help you plan for what’s next.

Budgeting: Your Financial Roadmap

A budget projects what you expect to earn and spend over a set period, usually a year. For new business owners, it’s a proactive tool that:

• Establishes spending limits aligned with your goals
• Ensures you allocate resources to areas that support growth
• Provides benchmarks for comparing actual results against expectations

Wendroff Pro Tip: Don’t treat your budget as static. Revisit it quarterly to adjust for changes in sales, expenses, or external conditions.

Forecasting: Preparing for What’s Ahead

Forecasting takes budgeting a step further by projecting future revenue, expenses, and cash flow based on trends and assumptions. Unlike a budget, which is planned at the start of the year, a forecast is updated throughout the year.

• Short-term forecasting helps you manage cash flow and day-to-day decisions
• Long-term forecasting supports strategic planning, such as hiring, expansion, or launching new products

Forecasting helps you anticipate slow seasons, plan for upcoming investments, and avoid surprises that could disrupt operations.

Wendroff Pro Tip: Overly optimistic forecasts can be just as harmful as failing to forecast at all. Stress-test your assumptions with worst-case scenarios so you’re prepared.

How Do You Build and Review a Budget & Forecast?

1. Set Clear Financial Goals – Decide whether your priority is growth, debt reduction, or building cash reserves.
   
2. Estimate Revenue – Use historical data plus realistic sales targets. Avoid overly ambitious assumptions.
   
3. Identify Fixed & Variable Costs – Know which expenses are predictable and which fluctuate with sales.
   
4. Plan for Capital Expenditures – Large purchases (such as equipment, vehicles, and software) should be included in the budget.
   
5. Run Multiple Scenarios – Create best-case, worst-case, and most-likely forecasts. This prepares you for surprises.
   
6. Compare Budget vs. Actuals Regularly – Monthly or quarterly reviews help you adjust spending and forecasts before problems snowball.
   
7. Use the Right Tools – Excel may work for startups, but accounting software like QuickBooks Online can automate reporting and forecasting as your business grows.
   

How Do P&L, Budgeting, and Forecasting Work Together?

Here’s an example of how these tools work together for a new business owner:

• You review your P&L and see that marketing expenses doubled last quarter without a corresponding bump in revenue.
• You adjust your budget for next quarter, reallocating some of that marketing spend to sales training.
• You update your forecast, running a scenario where sales increase 10% from better-trained staff.
• At your next P&L review, you compare actual results against your budget and forecast to see if your decision paid off.

This ongoing cycle – review, adjust, forecast – creates a proactive financial strategy rather than reacting to surprises.
