Three models, three stages of maturity
Most trade businesses evolve through three pricing models as they grow. Knowing where you are — and where you're going — is the difference between a shop that scales and one that's stuck trading time for money.
Time & materials (T&M)
You bill your hourly rate plus marked-up materials. It's transparent and low-risk on unpredictable jobs, which is why it's where most owners start. The problem is structural: your revenue is capped at your hours, customers feel every minute (and question it), and you get punished for being efficient — the faster you work, the less you bill. T&M is a fine floor. It's a bad ceiling.
Flat rate
You quote one price for the whole job, derived from a price book built on your real costs. This is the upgrade that changes the business:
- Customers prefer it. Certainty sells. A fixed number beats a meter running.
- Efficiency becomes profit. Beat your estimated time and your effective hourly rate climbs — you keep the gain instead of billing less.
- It scales to a team. A flat-rate price book lets a newer tech quote the same job the same way you would, without giving away margin.
The risk is estimating. Build your price book carefully, review it as costs move, and the occasional overage is dwarfed by the overall margin lift.
Service agreements
The most mature move, and the highest-leverage one — covered in depth in building recurring revenue. Customers pay a recurring fee for scheduled maintenance. It smooths your cash flow, fills your slow seasons, creates a pipeline of repair work, and — critically — raises the multiple a buyer will pay for the business.
Anchor everything to gross margin
Whatever model you use, the number that tells you if your pricing works is gross margin — revenue minus direct labor and materials, as a percent of revenue. For healthy residential service trades, that's 50–60%.
If you're consistently below 45%, the instinct is to chase more leads. Don't. Low margin on more volume just loses money faster. Below 45% is almost always a pricing problem — your rates don't cover your real costs — and the fix is the price book, not the marketing budget.
How to move up the ladder
- Know your real cost per hour (see the Start-track pricing basics) so every model is anchored to truth.
- Build a flat-rate price book from those costs and migrate off pure T&M.
- Launch a service-agreement program to layer recurring revenue on top.
Each step raises margin, smooths cash flow, and makes the business more valuable. Pricing isn't a one-time decision — it's the lever you pull as you grow.
