I spent six hours comparing estimating software last week.
Not because I needed a new tool. I wanted to understand why so many contractors I work with are using software that’s actively working against them.
They have spreadsheets that are five versions old. They have inherited templates from three years ago. They have formatting that looks professional but doesn’t actually cost the job correctly.

Take the free scorecard →Their estimating tool is dictating their pricing instead of supporting it.
The three tiers of estimating tools
Most contractors are in one of three situations.
Tier 1: The inherited spreadsheet. It’s an Excel file from 2019. Someone built it. It works most of the time. Nobody really understands it anymore because the person who built it left the company. You update it slightly for new projects and hope it still works.
This tool is broken, but you don’t know it’s broken until you compare your estimates to actual costs and realize you’re off by 8-15%.
Tier 2: The generic construction software. You bought a license to something that promises “estimating, job costing, and project management all in one.” It’s from a company that serves plumbers, electricians, framers, and remodelers.
It works okay for simple jobs. For complex jobs with custom work, you’re hacking around the constraints. You end up in spreadsheet mode halfway through anyway.
The tool is supposed to speed you up. Instead, you’re learning one system poorly instead of one system well.
Tier 3: The specialized tool built for what you actually do. You found or built a tool that’s designed specifically for residential remodeling. It understands your cost structure. It has templates for bathrooms, kitchens, additions, each with the right categories.
It’s expensive. It takes time to set up. But it removes the friction because it’s built for your actual work.
How the tool affects your pricing
This matters more than most contractors realize.
When your estimating tool doesn’t match your cost structure, you’re estimating for the tool instead of estimating for the job.
You have a category for “trim” and another for “hardware” and another for “installation.” The software wants you to pick one. The job has custom trim that’s half labor and half material. You arbitrarily pick a category. You’ve now lost cost clarity because you’ve shoehorned the job into a category instead of letting the cost structure match the actual work.
A better tool lets you build the cost structure to match your actual work. You can say “here’s labor, here’s material, here’s waste, here’s markup” for each element. You’re not forcing the job into predetermined boxes.
The result: your estimate is more accurate. You price with confidence. When the job comes in you know why (or why not) it hit your target.
Why I rebuilt our system
When I was running Casamia, we inherited an estimating spreadsheet from the previous owner. It was functional but not great.
We were estimating jobs at a 20% margin and actually delivering 15% because the estimate categories didn’t match our actual cost structure. We were baking labor and material waste into a single line item and not tracking them separately.
By year 2, I rebuilt the whole thing.
I created separate categories for:
- Base labor (crew time)
- Labor contingency (the overage we actually experienced)
- Material hard costs (the takeoff)
- Material waste (waste we actually experienced per material type)
- Material sourcing (the overhead of ordering and managing)
- Subcontractor costs
- Equipment rental
- Site management
- Permits and contingencies
Each category had subcategories. Labor had drywall, framing, finish, install, coordination. Each one had its own historical contingency because they had different overages.
The tool wasn’t fancy. It was a spreadsheet with a lot of detail and discipline.
But when we estimated a job, we could see our actual cost structure. We could price labor contingency at 18% because we knew we ran 18% over on labor. We could price material waste at 10% because that was real.
We stopped leaving money on the table because we were estimating what actually happened, not what we hoped would happen.
How to evaluate your own tool
Here’s what I’d check:
Does it match your cost structure? Can you create categories that match how you actually price jobs? Or are you forcing your work into predetermined boxes?
Does it separate labor, material, and waste? If you’re lumping these together, you can’t see which one is eating your margin.
Does it have historical data? Can you compare your estimates to actual costs? Can you see your real contingency by category?
Is it fast or is it friction? If it takes 40 minutes to estimate a job and the estimate is still inaccurate, it’s not serving you. A simpler tool that’s faster and more accurate is better.
Can you teach someone else to use it? If you’re the only person who understands the tool, it’s a liability. What happens when you take a week off or hire a new estimator?
Most contractors fail on the last one. Their estimating spreadsheet is so idiosyncratic that only they can use it.
The path forward
If you’re in Tier 1 (the inherited spreadsheet), your first move is to gut it. Look at your last 10 jobs. Figure out your actual cost structure.
Do you have separate contingency for labor vs material? Do you know your actual waste by category? Do you know what your sourcing overhead really is?
Build a new structure based on reality, not on what the spreadsheet already has.
If you’re in Tier 2 (the generic software), you’re paying for features you don’t use and not getting the features you need. The question is: is it fast enough that it’s worth the compromise? Or should you specialize?
If you’re in Tier 3 (specialized tool), you’re probably good. Just make sure you’re updating it as your actual costs change.
The tool should serve your pricing, not the other way around.
Most contractors have it backwards.
