I used to think that if the bottom line on my Profit and Loss (P&L) statement was green, I was winning the game.
Back when I was just starting to scale, I’d wait until the 15th of the month, open up my accounting software, and scroll straight to the bottom. If there was money left over, I’d breathe a sigh of relief, close the laptop, and get back to work. I thought I was being "fiscally responsible."
I was actually flying a plane by looking at the rearview mirror.
The problem with relying solely on your P&L is that it’s a history book. It tells you what happened last month, but it doesn't tell you why it happened, and it certainly doesn't tell you if you’re about to fly into a mountain tomorrow. As we’ve shifted Telos Bookkeeping to support a wider range of solo business owners: from those just starting out to those hitting that $10M revenue milestone: I’ve realized that the "medical-only" world didn't have a monopoly on financial confusion. Whether you’re running a boutique clinic or a growing digital agency, the math of scaling stays remarkably similar.
If you want to move from "surviving" to "scaling," you need to look beyond the P&L. You need a dashboard that tells you how the engine is running right now.
Here are the three numbers you should be tracking every day (or at least every week) to ensure your business doesn't just grow, but actually thrives.
1. Gross Profit Margin: Your Business’s "Fuel Efficiency"
Most owners are obsessed with "Top Line Revenue." It’s a vanity metric. You can have $5 million in revenue and be $1 million in debt. Revenue is the noise; Gross Profit Margin is the signal.
Why we use it
Gross Profit Margin (GPM) tells us how much money is left over after you pay for the "Cost of Goods Sold" (COGS): the direct costs required to deliver your service or product.
Value to you
Think of GPM as your business’s fuel efficiency. If you’re driving a semi-truck that gets 4 miles to the gallon, it doesn't matter how big your gas tank is; you’re going to spend a fortune just to move an inch. If your GPM is too low, you have to work twice as hard to keep the lights on.
What we do
At Telos, we don't just look at the dollar amount. We look at the percentage.
Formula: (Revenue – COGS) / Revenue = GPM%
If you’re a solo founder scaling toward $10M, your GPM needs to be healthy enough to fund your "back office" (marketing, rent, and your own salary). If your margin starts to dip, it’s usually a sign of "scope creep" or that your pricing hasn't kept up with inflation.

2. Payroll Percentage: The Weight of Your Engine
For most service-based businesses, payroll is the single largest expense. It’s also the most emotional one. Hiring your first employee is a milestone, but if you don't track the Payroll Percentage, that milestone can quickly become a millstone around your neck.
Why we use it
We calculate payroll as a percentage of your Gross Profit, not your total revenue. Why? Because you can’t pay people with money you’ve already spent on materials or subcontractors. You pay them from the "pot" that’s left over.
Value to you
Think of your team as the weight of the engine. If the engine is too heavy for the car’s frame, you won’t be able to accelerate. If your payroll percentage is creeping above 50-60% of your Gross Profit, you are likely overstaffed or under-productive. You’re essentially working for your employees instead of them working for the vision of the company.
What we do
We help our clients find the "Goldilocks Zone."
- Too low: You’re burning out, your quality is dropping, and you’re the bottleneck.
- Too high: You’re bleeding cash and have no "freedom fund" to reinvest in growth.
- Just right: You have enough support to stay in your "Zone of Genius" while maintaining a healthy financial reporting service rhythm.
3. OPEX Percentage: The Aerodynamic Drag
Operating Expenses (OPEX) are the costs of staying in business that aren't directly tied to producing your product: things like software subscriptions, rent, insurance, and that $200-a-month "research" budget you use for Amazon books.
Why we use it
OPEX is the "silent killer" of scaling businesses. It’s the "death by a thousand subscriptions." We track OPEX as a percentage of Gross Profit to see how much of your hard-earned margin is being eaten by overhead.
Value to you
OPEX is aerodynamic drag. Every unnecessary expense is like a parachute deployed behind your car. It might not stop you, but it sure makes the engine work harder. When you’re a solo owner scaling to $10M, you need to be as "lean" as possible.
What we do
We conduct "Subscription Audits." It’s amazing how many $49/month tools a business can accumulate over three years. By keeping your OPEX percentage within a specific range (usually 20-30% of Gross Profit, depending on your industry), we ensure that your growth actually results in more profit, not just more complexity.

The Transformation: From "Guessing" to "Knowing"
I used to think that "more revenue" was the answer to every problem.
- Short on cash? Sell more.
- Can't afford a new hire? Sell more.
- Stressed out? Sell more.
Now I believe that "better data" is the answer.
When you track these three numbers daily or weekly, the "fog of war" lifts. You stop making decisions based on your bank balance (which is a lie, by the way, because it doesn't account for upcoming taxes or uncleared checks) and start making decisions based on trajectory.
Scaling a business is a journey toward freedom and autonomy. But you can’t be free if you’re a slave to a spreadsheet you don't understand. Real growth happens when you take ownership of your numbers: just like you took ownership of your craft when you started this business.
How to Start Today
You don't need a PhD in finance to do this. You just need a system.
- Stop looking at Revenue alone. Start asking, "What was my Gross Profit this week?"
- Audit your team’s impact. Is your payroll fueling growth, or is it just a safety net for your own procrastination?
- Cut the parachutes. If you haven't logged into that software in 30 days, kill the subscription.
If you’re feeling overwhelmed by the "math" side of your $10M journey, that’s exactly why we’re here. We provide bookkeeping confidence so you can get back to the work you actually love.
Whether you’re in a medical practice or running a high-growth startup, the goal is the same: A business that serves your life, rather than a life that serves your business.
What’s the one number you’ve been avoiding looking at? Let’s face it together.
