T&M Pricing Is Costing You More Than You Think

I ran time-and-material service calls for sixteen years. Thought I was being smart. Every hour covered, every part marked up, no guessing. Safe.

I was wrong about what "safe" meant.

T&M Doesn't Protect You. It Just Feels Familiar.

You're never the one who guessed wrong on hours. The customer absorbs the risk. That's what you tell yourself at 6 a.m.

What you're actually running is a pricing model that hands every customer a reason to fight you at the door.

How long can you pay your guys with zero new revenue? Shops that don't know that answer aren't in control. They're comfortable. T&M is the same problem in different clothes. You're not protected. You're just familiar with the uncertainty.

Four-hour job, quoted T&M. Your apprentice runs it. Takes six hours. Customer opens the door, sees the invoice, wants to know why it took six hours when the other shop did it in four. Now your tech is standing on a porch explaining labor to someone who doesn't care about your apprentice's learning curve. That's where your margin goes. Not to materials. Not to drive time. To that porch.

You don't get that conversation on a flat-rate ticket.

Your Best Tech Is Your Worst Revenue Problem

On T&M, your best tech makes you less money than a slower one.

Your guy who's done a hundred expansion tank installs and runs one clean in forty-five minutes — he generates the same revenue as the new guy who takes two hours. Less, actually. You might bill two hours on the slow guy and feel guilty billing two on the fast one.

The working foreman — the guy who runs three guys and still gets dirty — he's the engine of a small shop. Fast, clean, no callbacks. On T&M, you are financially penalizing him for being good. Every minute he shaves off a call is a minute you don't bill.

Flat-rate breaks that. A skilled tech running a 45-minute job on a 2-hour flat-rate ticket is making real money for the shop. He earns it. You earn it. Nobody's apologizing.

The fabricated math I've seen in trade publications on this — "1.8 hours average versus 2.2 hours average" — I don't know where those numbers come from. What I know is my own book. When I rebuilt my residential ticket pricing off my actual costs and ran it for ninety days against the same period the prior year, the margin difference wasn't small. It wasn't rounding error. It was the difference between a shop that was covering truck notes and a shop that was building cash.

The Dispute Tax

In the fall of 2011 I made two decisions in the same season. I fired Whitman Builders over $61,000 in receivables — they eventually paid 38 cents on the dollar in the bankruptcy. And I stopped running T&M on residential service calls.

I was done letting other people audit my work after the fact.

I had a customer in Shrewsbury. Called us for a water heater expansion tank and a PRV swap — routine work, maybe two and a half hours. My tech ran it longer because there was old galvanized in the line that needed to come out before the PRV would seat right. He wrote the invoice: time plus materials.

She met him at the door. Said the truck hadn't been there as long as the invoice claimed. She'd watched it.

She wasn't wrong to push back. I'd handed her something to push back on. A labor line is an invitation to negotiate. And some customers will take it.

A flat-rate ticket reading "Water Heater Expansion Tank Install" with a price on it doesn't give her a clock to watch. The job is the job. The price is the price. She approves it before work starts or she doesn't.

My tech spent forty minutes on that porch. I spent twenty on the phone. She paid. She didn't call back. The whole thing felt like a negotiation after the fact, which is the worst experience you can give someone who let you into their house.

That was the last T&M residential service call I ran.

The Flat-Rate Book Is Training Wheels

I'm not here to sell you a pricing subscription.

The books are fine for a year. If you're coming off a clipboard and writing T&M invoices in your truck by feel, a flat-rate book will feel like someone turned the lights on. Use it. Learn how it's built.

Then build your own.

A shop in Worcester paying a tech $34 an hour, running two truck notes, carrying workers' comp in a state that charges what Massachusetts charges — that shop and a one-man operation in rural Tennessee are not the same business. They should not charge the same price for a ball valve swap. But if you're both on the same subscription book, you are. One of you is probably fine. The other is slowly going broke and calling it a pricing problem when it's a thinking problem.

Every shop I've talked to that stayed on a subscription for three or four years without building their own rates had the same symptom: they couldn't tell you if they were making money on a job. Job closed, customer paid. Margin per job against what the flat-rate ticket actually paid? Nothing. No answer.

You can't run the 90-day math if you don't own your numbers. If your prices came from someone else's spreadsheet, you don't know what weather you're flying in.

What the Transition Actually Costs You

The first month feels like you're losing jobs you used to win. Your dispatcher is quoting numbers that feel high. Your close rate dips. A customer or two goes with someone cheaper.

Here's what I learned in month two: the jobs I was losing were jobs I'd been losing money on already. A customer who walks because your flat-rate price on an expansion tank install is higher than your old T&M number was a customer you were subsidizing. You just didn't know it because you weren't doing the math.

Then something changes. Customers who stay are buying the job, not watching the clock. Your techs stop getting questions at the door. The close rate comes back — not entirely, but the jobs closing are better jobs.

The staff friction is real. The guy who's been running T&M for eight years hears "we're switching to flat-rate" and his brain goes to one place: someone thinks he's stealing time. That's the read. I've seen it. It's not paranoid, it's how a tradesman who takes pride in his work processes a change to how his work gets measured.

I wouldn't announce this in a meeting. I'd have it across a workbench, one guy at a time. Something like: "The way we've been doing it, your best day and your worst day pay the customer the same. That ain't right. Flat-rate means when you run a clean job fast, we both make more money." Not about trust. About giving the fast, good tech a model that rewards him.

What to Do Monday Morning

Pick one service category. Water heaters. Expansion tanks. Drain cleaning. Something you do ten times a month with predictable labor and predictable parts. Build three to five flat-rate tickets from your own numbers — your actual labor rate, your actual truck cost, your actual parts cost with your actual markup. Run those for thirty days before you touch anything else.

Write the real price into the tickets from day one. Shops that soft-pedal the conversion — price it low to ease customers in, plan to raise rates later — just recreate the T&M problem with a different label. Your ticket has to reflect what the job costs you to run, plus margin. Not the shop down the street. Not what you think the customer will accept. What it actually costs you.

The moment you'll know your conversion is real is the first time a customer pushes back and your tech holds the number.

He needs one sentence ready. Not an apology. Not an overhead explanation. Something like: "That's our price for this job, covers everything — parts, labor, the works." Full stop. No invitation to counter.

Run that conversation in the shop first. You and your tech, door and customer, before it's real. It feels ridiculous for three minutes. The first real pushback he handles clean, you'll be glad you did it.

At day ninety, pull your numbers and compare them to the same ninety days the prior year on T&M. That comparison will either confirm the model or tell you something specific is wrong with your ticket pricing. Either way, you'll know what you're looking at instead of guessing.

Two Questions I Actually Get

My best tech is slow and thorough. Won't flat-rate punish him?

Depends on why he's slow. If it's because he does complete work with no callbacks, that's different from a tech who just runs long. Flat-rate rewards speed, but the reward only lands if the speed doesn't generate returns. A thorough tech with zero callbacks and strong repeat business — that value is real. If flat-rate is making him anxious, sit across the workbench and tell him you're timing the job, not the man.

Some of my builder clients ask for T&M on remodels. Do I hold the line?

Make the exception. But your T&M rate on remodel work with a GC needs to be high enough to cover the invoice scrutiny, the payment float, and the dispute drag. I had Whitman Builders on what I thought were reasonable T&M terms. I walked away with 38 cents on the dollar. Before the first man rolls on any GC job — T&M or otherwise — I want payment terms in writing. Thirty days. No pay-when-paid language. If they won't sign that, the rate isn't high enough to make it worth the risk.
