1. The Personal Hook
I’m in my late twenties, and most of my friends fall into three camps: bankers, business owners, and the stuck.
We all came from similar schools, but our careers split into three tracks.
Those who stayed in finance or banking make good salaries.
Some started their own businesses — painting, roofing, landscaping, promotions, “influencing” — and either crushed it or struggled but loved the freedom.
And some got stuck in jobs that don’t really lead anywhere.
My line of work is organizing financial data so people can actually see if they’re making or losing money — and how much. Because of that, I have a front-row seat to that second group: entrepreneurs who’ve been at it 10–20 years. Over time, a pattern always emerges.
The people with the most upside are the ones who truly understand how money moves through a business.
2. Contracting Is a Financial Chain
Most people see contractors as service providers. But behind every brushstroke or renovation is a system of money moving through marketing, sales, production, and operations.
A successful painting company isn’t just “doing jobs.” It’s managing cash flow timing, departmental costs, and conversion rates from lead to closed sale.
I’ve had the benefit of seeing this up close — and I want to share what I’ve learned.
3. The Journey of a Single Dollar
Let’s follow one customer dollar through a contracting business:
| Stage | What Happens | % of Dollar |
|---|---|---|
| Marketing | Cost to acquire leads (ads, SEO, referrals) | -11% |
| Sales/Estimating | Sending estimator, intake forms, follow-up | -12% |
| Production | Painters, materials, production managers | -55% |
| Admin/Operations | Office staff, communication, scheduling | -9% |
| Payment Processing | Transaction fees | -3% |
| Profit | Net after all overhead | +10% |
(These vary, but this breakdown is typical for efficient residential contracting businesses with an average job size around $5K.)
4. Timing the Cash Flow
This is where contractors live or die — timing.
Even profitable companies can go broke if their cash flow timing is off.
Week 1: Pay for ads → leads start coming in
Week 2: Pay estimator and admin time → deliver quotes, collect specs
Week 3: Customer books the job and pays a 50% deposit
Weeks 4–5: Purchase materials, schedule crews, begin production
Week 6: Job completed → collect remaining 50%
Week 7: Pay labor and suppliers → profit realized
This rhythm creates what I call the Cash Flow Gap — the period between spending on marketing and receiving final payment.
The best-run companies know exactly how long that gap lasts — and plan around it.
Example 1: Standard Flow
| Stage | What Happens | % of Dollar | Net Cash | Notes |
|---|---|---|---|---|
| Marketing | Acquire leads | -11% | -11% | Negative cash flow |
| Sales/Estimating | Quotes & follow-up | -12% | -23% | Negative |
| Initial Deposit | 50% up-front | +50% | +27% | Positive |
| Payment Processing | Fees (half) | -1.5% | +26% | Positive |
| Production | Labor & materials | -55% | -30% | Negative |
| Admin/Operations | Office & scheduling | -9% | -39% | Negative |
| Final Deposit | Remaining 50% | +50% | +12% | Positive |
| Payment Processing | Fees (half) | -1.5% | +10% | Positive |
| Profit | After all overhead | +10% |
Even here, timing matters. Suppose a job takes less than five days and painters are paid biweekly — the 50% deposit may hit before payroll, making you cash-flow positive right away.
If materials are bought on a credit card with 30-day terms, the advantage grows.
Example 2: Optimized Timing
| Stage | What Happens | % of Dollar | Net Cash | Notes |
| Marketing | Acquire leads | -11% | -11% | |
| Sales/Estimating | Quotes & follow-up | -12% | -23% | |
| Initial Deposit | 50% up-front | +50% | +27% | Positive |
| Payment Processing | Fees (half) | -1.5% | +26% | Positive |
| Final Deposit | Remaining 50% | +50% | +76% | Positive |
| Payment Processing | Fees (half) | -1.5% | +74% | Positive |
| Production | Labor & materials | -55% | +19% | Positive |
| Admin/Operations | Office & scheduling | -9% | +10% | Positive |
| Profit | After all overhead | +10% |
That’s real leverage — understanding not just how profitable a job is, but when you actually see the cash.
5. What the Data Shows
Across the internal data I’ve reviewed, the top-performing contractors all do a few things differently:
- They track cost per lead, cost per estimate, and cost per job won.
- They budget production (labor + materials) as a fixed % of job price.
- They recognize that admin time — scheduling, confirming details, client communication — is a real, measurable cost.
- And most importantly, they manage cash flow timing, not just profit margin.
Put simply:
Contractors who understand their numbers build wealth.
Contractors who don’t burn cash without realizing where it’s going.
6. The Bigger Picture
These mechanics apply to every trade — roofing, electrical, plumbing, flooring.
You pay upfront to get the customer.
You deliver a service that’s part labor, part materials.
You rely on timing, efficiency, and process to stay profitable.
The numbers shift, but the pattern never changes.
7. The Takeaway
If you’re running or thinking about starting a contracting business, step back from the brush or the wrench and look at the flow of a dollar.
Every business has a rhythm: marketing, sales, production, delivery, cash-in.
Learn it. Measure it.
Master that rhythm, and you’ll scale faster — and with less stress — than 90% of your competition.
