Why Your Technicians Are Underquoting Jobs (And How to Stop It)

The Problem Nobody Talks About

You're losing money on every estimate your technicians write. Not because they're dishonest—they're not. But because they're quoting in the dark.

Here's what happens: A plumber gets a call Tuesday morning. Customer needs a water heater replacement in a tight crawlspace, plus rerouting some copper lines. The tech has done this maybe eight times in the past two years. But does he remember what he charged in 2023? Does he know whether copper prices have moved? Does he know if that same job in a similar Burnaby neighbourhood went for $2,400 or $2,800? Almost never.

So he quotes what feels right—or what he quoted last month for something vaguely similar. He might be $500 under. He might be $800 under. Over a year, across your whole team, that's real money walking out the door.

Why This Happens

Your technicians aren't lazy or careless. They're working with incomplete information.

• No access to your own history. Your job records exist—in email, old invoices, maybe a spreadsheet nobody updates. Your tech doesn't have them in his pocket when he's on a call or at the job site.
• Regional costs shift quietly. Material prices, labour rates, and seasonal demand move. A job that cost $1,800 to quote in January might legitimately be $2,100 in July. Your team doesn't see that signal.
• Complexity gets undervalued. A straightforward furnace swap is one thing. But if the ductwork is corroded, or the electrical needs upgrading, or the install is in a crawlspace—those factors should move the quote up. Without a checklist or a system, they often don't.
• Memory is unreliable. Even your best tech can't recall 200 jobs accurately. He remembers the dramatic ones, not the typical ones.

What This Costs You

Let's be concrete. A $1.2M HVAC business in the Lower Mainland might write 40–60 quotes a month. If the average underquote is $400–$700 per job, and your close rate is 40–50%, you're losing $6,400–$14,000 a month in margin. That's $77,000–$168,000 a year.

Even a smaller plumbing operation—say, 20 quotes a month at a 45% close rate—might be leaving $3,600–$6,300 annually on the table.

And that's just the direct cost. Underquoting also trains your customers to expect lower prices, makes it harder to raise rates, and can make a job unprofitable if complications emerge mid-work.

How to Fix It

Give your technicians instant access to their own data.

When a tech pulls up a job on his phone—or better, when he's sitting in the customer's home—he should be able to search your past jobs by type, location, and date. "Water heater replacement, East Vancouver, last 12 months." Boom. He sees three similar jobs: $2,200, $2,350, $2,100. He now has a real anchor, not a guess.

Build a simple complexity checklist into your quoting process.

Before the tech hits "send" on an estimate, a few yes/no questions should trigger price adjustments: - Is the work in a confined space (crawlspace, attic, basement)? - Does it require rerouting or upgrades to other systems? - Is it an emergency or after-hours call?

Each "yes" bumps the quote by a percentage or a flat amount. Consistent, defensible, fair.

Track regional and seasonal benchmarks.

Once a month, your office manager or dispatcher should flag material price changes or seasonal demand spikes. A simple Slack message—"Copper is up 8% this month" or "July is peak HVAC season; add 10% to labour estimates"—keeps your team in sync.

Review underquotes in your team huddles.

When a job comes in under budget (or over), mention it. "Hey, that furnace swap we quoted at $2,100 came in at $1,950 in materials—looks like prices dropped. Let's adjust next month's quotes." Your team learns and recalibrates.

The Upside

When your technicians quote faster and more accurately, several things improve:

• Fewer back-and-forth emails asking for clarification or revised estimates.
• Higher close rates because customers get answers the same day.
• More confident technicians who feel supported by data, not guessing.
• Consistent margins across your business, even as markets shift.

Your team already has the knowledge. They just need the tools to use it.
