Most owners can tell you exactly how busy they are. Far fewer can tell you, with confidence, whether the business is actually making money.
That’s not a knowledge problem. It’s a visibility problem. You don’t need an MBA or a full-time CFO to fix it, you need five numbers, tracked consistently, and a plain understanding of what each one is telling you.
1. Cash Runway
If your revenue stopped completely today, how many months could you keep paying the bills before you ran out of cash? That’s cash runway, and it’s calculated simply: cash on hand divided by average monthly expenses.
Profit and cash are not the same thing. It’s entirely possible to be profitable on paper and still run out of cash, especially in seasonal or project-based businesses. Aim for at least 3 to 6 months of runway. Less than that, and a single slow month or a late-paying client can put real pressure on the business.
2. Gross Profit Margin
Of every dollar that comes in, how much is left after paying for the direct cost of delivering your product or service? Gross profit margin, calculated as (revenue minus cost of goods sold) divided by revenue, tells you whether your core pricing actually works, before rent, software, or any other overhead even enters the picture.
This varies widely by industry. Service businesses often run 50 to 70 percent; product and retail businesses often run 20 to 40 percent. Know your own number, and watch the trend more than the absolute figure. Margin trending downward over several consecutive months, especially while revenue is growing, often means you’re winning less profitable work.
3. Net Profit Margin
After absolutely everything is paid, rent, payroll, software, taxes, interest, how much of each revenue dollar do you actually keep? Revenue growth means very little if this number is flat or shrinking. This is the real scoreboard for the health of the business, not how busy it looks from the outside.
Most small businesses land somewhere between 5 and 20 percent, depending on industry and business model. A net margin near zero or negative, particularly while revenue is increasing, is the classic sign of growing your way into a cash problem.
4. Days Sales Outstanding (DSO)
On average, how many days does it actually take a customer to pay an invoice after you send it? A sale isn’t real cash until it’s actually collected. Slow-paying customers can quietly starve an otherwise growing, profitable business of the cash it needs to operate.
Under 45 days is generally healthy for most small businesses, but the right number depends on your own stated payment terms. Watch for DSO steadily climbing month over month, or a small handful of clients consistently paying far past your stated terms.
5. Revenue Growth Rate
Is the business actually growing, and how fast, compared to last month or last year? Owners often feel busier without knowing whether revenue is actually increasing, or simply shifting around. This number replaces that feeling with an actual answer.
Track both month-over-month, for short-term trend, and year-over-year, which removes normal seasonal swings from the picture. Flat or declining growth for two or more consecutive periods, with no obvious explainable cause, is worth investigating.
Knowing the Numbers Is Step One
Tracking these five numbers will tell you more about your business than almost anything else you could measure. But numbers alone don’t fix a cash crunch, fix a pricing problem, or tell you whether you can afford to hire. That’s exactly the gap CFO advisory is built to close: turning these numbers into a plan, and turning that plan into decisions you can actually act on.
