Software for Contractors: Check This Before You Buy

October 4, 2026

This is the video behind the post. It walks a heating and cooling shop through all 3 steps, so you can see a fix turn up in software the owner already paid for.

Before you buy any software for contractors, run 1 check. Look at what you already pay for, run 3 questions on the tool, then write down build or rent and why.

This post is not a list of products. It doesn’t rank them, and it won’t tell you which one to buy. It’s the check to run first, so that you don’t pay twice.

Software for contractors: why the better pitch wins

You know your bottleneck now. So you go looking for a fix. If you don’t have yours yet, find your business bottleneck first.

1 person says buy this app. Another says have it built.

You can’t tell who’s right, so you go with the better pitch. And a few months later, you’re paying for the wrong fix.

You’d think the choice is build or rent. It isn’t yet. First, check what you already pay for.

Then the rule is short. Rent the commodity, build the advantage, own the decision.

Commodity means the same for every business, like email or card payments. Advantage means how you win, like how you follow up.

The full version of that rule is in build vs buy software. This post turns the rule into 1 decision. It takes 3 steps, and they go in order.

Step 1: check what you already pay for

This step stops you paying for a fix you already have.

You check the truck for the part before you drive to the supplier.

So ask 1 question: “Does software I already pay for fix this?”

It’s the question most owners skip.

Some field service software now answers your calls with AI. Housecall Pro, software that runs home service businesses, sells that as an add-on.

Buildertrend, software for builders, can invoice straight from a change order.

If yours does it, turn it on. That’s renting the commodity, and it’s often the simplest fix.

In the video, say Tess runs a small heating and cooling shop. She’s made up, but her week will sound familiar.

Her bottleneck was missed calls. A company quoted her on a custom phone system.

Then she checked. Her own software sold call answering as an add-on. She turned it on. Nothing to build.

The mistake is shopping before you look at what you have.

Nothing you own does it? That’s fine. Go to step 2.

Write down what you found. Keep it for step 3. (Step 1 in the video)

Step 2: run the 3 questions

This step sorts any tool into build or rent.

You buy the van off the lot. You fit out the back yourself.

So take the tool, and ask 3 questions:

1. “Is this how I win, or is it a commodity?”
2. “Could I keep it running if I built it?”
3. “Does the rented one fit how I work?” Or does it force you to change how you work?

Take accounting. QuickBooks is accounting software, and it does the job. It’s a commodity, and it fits. So rent it.

Now take your quote follow-up. That’s how you win, and it has to work your way. So build it.

Here’s why. You make the call with your eyes open.

If you’ve been stuck on custom vs off the shelf software, these 3 questions are how I’d sort it. The Business Development Bank of Canada asks the same thing about bigger company software in custom or off-the-shelf systems.

Now try the 3 questions on a tool you’re about to renew. You may be renting your advantage. Or paying to build a commodity.

The mistake is letting the best pitch answer for you.

That’s your 3 answers. Hold onto them for step 3. (Step 2 in the video)

Step 3: decide, and write the reason

This step makes the decision yours, with the reason on paper.

On a job, a change gets written down before anyone picks up a tool.

So take your bottleneck. Take what you found in step 1, and your 3 answers.

Then write 1 line. Build or rent, and why.

Tess writes, “Rent. Every shop needs calls answered, and my software does it.”

The mistake is deciding while someone is selling to you. The right move is deciding on paper first.

And if the answer is rent, that’s fine. Rent the good ones. Before you sign up for one, the Government of Canada’s Get Cyber Safe guide for small and medium businesses is worth a read. (Step 3 in the video)

Why the order matters

Check what you pay for. Run the 3 questions. Decide, and write why.

Skip step 1, and you may pay for a fix you already have. Skip step 2, and the best pitch may decide for you. Skip step 3, and the decision may never get made.

Write your 1 line

Now write yours. Build or rent, and why.

1 short line will do:

“____. Because ____.”

Put build or rent in the first blank. Put your own reason in the second.

Not sure which problem to run this on? Which business problem to fix first shows you how to pick 1 by what it costs you.

Try it on your own bottleneck

Here’s your move for this week: take your bottleneck, and write 1 line. Build or rent, and why.

If you want help with it, the full lesson is free in my Skool community. It’s lesson 2.4 in Map Your Business, and the 3 questions are there to copy. Then post build or rent, and your 1 line reason, in your Build Card thread.
