How to Read Your Profit & Loss Statement (Without Falling Asleep!) | Small Business Guide
I get it, as a small business owner the term Profit & Loss Statement (P&L) can make one shudder. Financial reports can feel overwhelming, and sometimes accountants throw around jargon like you’re supposed to just “know” what it means.
But here’s the truth: your P&L is more than just a bunch of numbers. It’s your business’s story—showing where your money comes from, where it’s going, and how much is left over. Once you understand it, you can make smarter decisions, spot problems early, and set yourself up for more profit.
And with the right tools (like QuickBooks Online), you can make this report simple, relevant, and even—dare I say—interesting.
What Is a Profit & Loss Statement?
A Profit & Loss Statement (also called an Income Statement) is a financial report that shows:
- Revenue (Income) – How much money your business earned.
- Expenses – How much you spent to keep your business running.
- Net Profit (or Loss) – What’s left after expenses.
It typically covers a specific time period (monthly, quarterly, or yearly) and answers big-picture questions like:
- Am I making money?
- Are my expenses too high?
- Which months are the most profitable?
- Do I need to adjust my pricing or cut costs?
Breaking Down the Sections of a P&L
1. Revenue (Top Line)
This is all the income your business has earned before subtracting expenses. Depending on your business type, this might be:
- Sales from products
- Service fees
- Membership dues
- Donations (for nonprofits)
In QuickBooks Online, you can break this down into different income categories so you can see exactly which streams are most profitable.
2. Cost of Goods Sold (COGS)
These are the direct costs of producing your products or delivering your services.
Examples:
- Product-based business: raw materials, manufacturing costs, shipping.
- Service-based business: subcontractor payments, software used to deliver services.
- Nonprofits: program delivery costs.
QuickBooks tracks COGS separately so you can see your gross profit—revenue minus COGS.
3. Operating Expenses
These are the costs of running your business that aren’t tied directly to production. Examples include rent, utilities, marketing, payroll, and office supplies. This is where “small” recurring expenses can quietly eat into profit.
4. Net Profit (or Loss)
The famous “bottom line.” If this number is positive, you’re profitable. If negative, you’re spending more than you earn. This is your ultimate measure of financial health.
Why Small Business Owners Struggle With P&L Statements
- The numbers feel meaningless without context.
- Reports are too generic for their specific business model.
- They run it once a year for taxes but don’t use it to guide operations.
This is where customizing your P&L in QuickBooks Online changes the game.

P&L Insights for Different Business Types (With Practical Examples)
Service-Based Businesses
Service-based owners—consultants, salons, agencies—often have inconsistent income and less obvious COGS.
Common P&L issues:
- Forgetting subcontractor costs in COGS.
- Not separating billable tools/software from general expenses.
- Hard-to-read monthly trends due to irregular income.
QuickBooks Tip: Set up classes for each service type. Filter your P&L by class to see which services are most profitable.
Example: A marketing agency runs a P&L by class and discovers their social media management service has a 65% margin, while their website design service only has a 30% margin due to contractor costs. They shift focus to social media packages, boosting overall profitability.
Product-Based Businesses
Retail, e-commerce, and manufacturing businesses often face messy inventory tracking and hidden shipping costs.
Common P&L issues:
- Inventory not properly matched to sales.
- Shipping costs buried in operating expenses instead of COGS.
- Discounts and returns skewing revenue.
QuickBooks Tip: Integrate QuickBooks with your POS or e-commerce platform to sync sales, COGS, and inventory automatically.
Example: An online boutique integrates QuickBooks with Shopify. Their P&L shows that a best-selling dress has a 15% profit margin after shipping and returns. They renegotiate with their supplier and raise prices slightly, improving the margin to 28%.
Nonprofits
Nonprofits use a P&L (often called a Statement of Activities) to track program performance and funding allocation.
Common P&L issues:
- Not separating restricted vs. unrestricted funds.
- Mixing program expenses with administrative expenses.
- Categories that don’t match grant reporting needs.
QuickBooks Tip: Use class tracking to assign each transaction to a program or funding source. Run your P&L by class for clear program-level results.
Example: A youth mentorship nonprofit runs a P&L by program and finds their after-school program runs a $5,000 annual deficit, while the summer program has a surplus. They use this insight to apply for a grant specifically for the after-school program.
How to Read Your P&L Without Falling Asleep

- Scan for Expense Changes – Look for spikes in categories.
- Check the Bottom Line – Is your net profit margin healthy for your industry?

How Often Should You Review Your P&L?
- Monthly: For decision-making and early issue detection.
- Quarterly: For strategic planning.
- Annually: For tax preparation and year-end review.
Using Your P&L to Make Real Decisions
