Historic peak was 2.87%. October hit 16.6% — a 4–5x jump
Given away in discounts in a single month before the fix
Unchanged through the price increase. Not one sale lost to higher prices.
From a prior-year loss to a profitable year.
In 7 months, an $8M foundation repair and waterproofing company went from a $300,000 net loss to a 16.6% profit margin — without adding any extra volume. The owner ended the year buying a BMW and learning to fly a plane. The problem wasn't the market, the economy, or a bad team. It was a flat 10% commission plan that made discounting completely free for every sales rep. In one month alone, the team gave away $353,000 in discounts. The fix was three moves: a 3% price increase, a new commission structure that penalized discounting, and monthly P&L visibility. The close rate never moved.
We'll call the company Solid Ground Waterproofing. The owner has asked us to keep the details anonymous, but the numbers are real and drawn directly from the engagement record. We'll call him Derek.
"I'm about to see who's giving away my farm on my orders. Honeymoon's over, guys."
Derek said this on a call in August 2025, pulling a discount report from his CRM while Stuart Trier watched. He'd never run the report before. Nobody had told him to. He started reading the numbers out loud.
The total for July: $353,000 in discounts. Given away by his own sales team. In a single month.
His reaction was immediate:
"That's where my profit's all going. We're giving it away to the customer."
Back up a year. Solid Ground Waterproofing had crossed $8M in sales the prior year and posted a $300,000 net loss. Derek had three explanations for it: the company was still getting efficient on foundation repair, a Chicago permitting process had delayed jobs and forced refund of deposits, and a new crawlspace underpinning service had cost more to launch than it earned in its first year. All three were true. None of them was the main problem.
Derek is 39. He started the company at 23, posting ads on Craigslist for epoxy crack repairs after leaving a job plowing roads for the Department of Transportation. The company grew organically — one job, then two, then a crew, then five crews — until it became something he never planned for it to be. "If you look at this," he told Stuart on their first call, "you'll probably start to see what's more looking like a patchwork quilt than a company that was built from the ground up."
By July 2025, he had 50 employees, 7 sales reps, and a fixed overhead built for $10M in revenue that he wasn't hitting yet. He was doing his own bookkeeping — roughly 10 hours a week — and handling marketing coordination on top of it. "I've been doing this for 15 years," he said, "and I'm almost 40, but I don't own a house and everything I've done, I've put right into this."
He wasn't looking for motivation. He was looking for the leak.
When Stuart asked him to pull the discount report, they both found it.
Stuart Trier has run nearly 1,800 coaching calls with home service operators since 2022. He saw the problem immediately.
"Incentives drive the world," he told Derek. "If it costs them nothing, they're going to be like, why not discount them?"
That's exactly what was happening. Derek's sales reps were on a flat 10% commission. Whether they sold a job at full price or took 10% off the top, their commission rate didn't change. Discounting was free for them. It was coming entirely out of Derek's margin.
The math is brutal once you see it. If a job carries an 8% net margin and a rep drops the price by 2%, they've just given away 25% of the company's profit on that job — and their own paycheck barely moves. Under a flat commission structure, there is no financial argument for holding price. The rep absorbs none of the pain. The company absorbs all of it.
Derek pulled the breakdown by rep. Everyone was doing it. "Ryan did the most. Mike actually did pretty high up there. Steve had a great month, but he discounted the shit out of it. So did Chris."
The month he was looking at — July 2025 — had a 35% close rate. Not catastrophic. But the margin was gone. "Divided, it took away 63% of the profit. Damn," Derek said, doing the math live.
And here's the thing: the company wasn't even losing jobs to competitors. The close rate told them that. Customers were buying. They just weren't paying full price — because nobody was asking them to.
A flat commission rate pays the same percentage regardless of what price the rep closes at. A rep earning 10% makes $350 on a $3,500 job and $300 on the same job discounted to $3,000. The difference is $50. That's not enough to change behavior.
Commission incentive alignment means restructuring the rate so that the financial gap between discounting and not discounting is large enough to matter. In practice: raise the full-price rate above the old flat rate, and cut the rate on discounted jobs sharply. The rep who sells at full price earns more than they did before. The rep who discounts earns meaningfully less.
Under the restructured plan at Solid Ground Waterproofing: full price = 11% (up from 10%). Discount of up to 5% = the rep splits the discount with the company, earning roughly 5–6% on the discounted amount. Discount beyond 5% = 0% commission on that sale.
On a $3,500 job: full price at 11% = $385. Discounted to $3,000 at the old 10% = $300. The gap just went from $50 to $85 — and that's before you factor in that the rep now gets nothing if they discount too aggressively. The incentive is no longer pointing at the discount.
Derek raised prices 3% across all waterproofing and foundation products. It took about a minute in the estimating software — he selected all waterproofing products, raised them 3%, then did the same for foundation products. Done.
His instinct was to be transparent about it with the team. "I want them all bought in and on the same team here to win." He told the reps directly: prices are going up, and here's why. The increase was framing as much as anything else — it gave the reps a higher base to work from and made the new 11% rate feel even more like a genuine raise.
The new structure had three tiers. Full price: 11% (up from 10%). Discount of up to 5%: the rep splits the lost margin with the company. Discount beyond 5%: 0% commission on that job.
Stuart originally asked why Derek would allow any discount at all. Derek's answer: sometimes customers just want to feel like they got a deal. So they built in a workaround. Reps could anchor the price 3% higher and then "discount" back to the original — earning 11% on the net price either way. Derek put a $0 product flag in the CRM for tracking. By early September, he confirmed: "Anyone who's given a discount is marking it up first, and we have a process for that."
The rollout conversation with the team took one session. "They're super excited about being able to make more," Derek reported the following week. The reaction was almost universal: reps saw it as a raise. Because it was.
The third move was the simplest and in some ways the most important. Derek moved from quarterly financial reviews — which were really catch-up sessions to figure out what had happened — to monthly P&L reviews as a management tool. Margin was now visible in near-real time. Leadership could see the numbers and hold the line instead of finding out 90 days too late.
The change worked faster than anyone expected.
By September 4 — less than a month after the new structure went live — Derek reported sales of $221,000 in the previous week and $129,000 already that week. The team was winning jobs priced $6,000 above competitors. One rep had immediately re-sent every open proposal at the new full price, with a note that the discounted version had expired by the original deadline. Customers bought. The rep declared: "I'm never discounting again."
Derek summarised the shift:
"They took their mind off price, which took the conversation off price, which took the customer's mind off price, and they just started selling."
August closed at $753,000. The top rep, Mike, crossed $1.3M for the year by mid-September. Month-to-date sales on September 15 were $380,000.
October was the number that confirmed it. Net profit: 16.6%. On $872,000 in revenue, that's roughly $145,000 in operating profit. A month earlier, the historic peak had been 2.87%. The close rate through all of this: 42.21% — essentially identical to where it had been before the price increase and commission restructure. Not one sale lost.
The friction: in November, Stuart pushed to move sales commissions into Cost of Goods Sold for cleaner margin visibility at the job level. Derek pushed back, with a legitimate operational reason: the variable penalty rates — 0%, 5%, or 11% depending on what happened on the sale — meant the job costing team couldn't finalize a job's margin the day after completion without knowing which commission rate applied. Moving commissions into COGS would require a process change that created real work for the people running job costing daily. Stuart conceded the point. "I'm not trying to create paperwork for the sake of creating paperwork." Real engagements have this kind of friction. The fix isn't always the clean version.
By January 2026, the company had its strongest January on record: $522,000 compared to $215,000 the prior year — a 143% increase year-over-year. The full year closed with approximately $393,000 in net profit, against a $300,000 net loss twelve months earlier.
Derek put it plainly:
"Last year we didn't have a profit to show. Now we're going to be showing somewhere around $393,000."
He bought a BMW. He bought a plane. "Now I just got to learn how to fly this thing."
The commission problem at Solid Ground Waterproofing is not a waterproofing problem. It's a compensation structure problem. It shows up in every trade where sales reps are on flat commission and have the authority to discount.
These trades have long estimation cycles and large job sizes. The flat commission problem is most acute here because the absolute dollar amount involved is high. A 5% discount on a $50,000 foundation job is $2,500. The rep's commission changes by at most $250. The company loses $2,500 in margin. At this job size, even a 2% discount is enough to wipe out meaningful profit — and under a flat structure, there's no financial reason for the rep not to offer it.
The penalty tier structure applies directly. The mark-up loophole also applies: reps can anchor at a higher price and "discount" it to the original, giving the customer the psychological win of getting a deal without touching the actual margin. This works especially well in trades where customers expect to negotiate.
Smaller job sizes, higher frequency. A flat-rate service call at $299 with a 10% discount becomes $269. Small in absolute terms. Catastrophic at volume across hundreds of calls a month. The logic is identical: discounting costs the rep almost nothing and costs the company its margin.
The structure is simpler at this job size — two tiers instead of three, with a clear floor below which reps don't discount at all, is usually enough. The principle is the same: hold price, earn more. Cut price, earn less. The gap has to be large enough to change behavior.
The cross-trade test is simple: pull your discount report right now. Filter by rep. Add up the total discounts given in the last 30 days. That number is the floor of what you're giving away. The ceiling is what your margin would look like if you'd sold every one of those jobs at full price.
Derek's business was generating strong sales. The team was good. The product was good. The jobs were getting done. None of that was the problem. The problem was a single line in a compensation plan that nobody had ever questioned — because the company was growing and the business felt like it was working.
$353,000 a month says otherwise.
The fix wasn't complicated. It didn't require firing anyone, cutting overhead, or finding more customers. It required changing what behavior the commission plan rewarded. Once the incentive pointed in the right direction, the team moved with it almost immediately.
Worth keeping in mind: the same commission-structure problem exists in every home-service business where reps have the authority to discount and pay nothing for the privilege. The discount report is sitting in your CRM right now. The question is whether anyone has pulled it.

How do I know if my sales commission structure is causing margin leakage in my home service business?
Pull your CRM or job-costing report and filter by the discount applied. If reps are routinely discounting 5% or more to close deals, and those discounts cost them nothing in commission, the structure is leaking margin. A flat commission rate — where a rep earns the same percentage whether they discount or not — removes all financial incentive to hold price. The test is simple: does discounting cost the rep money? If the answer is no, it will cost you.

What is commission incentive alignment and how does it affect home service profit margins?
Commission incentive alignment means structuring rep pay so that holding price pays more than cutting it — and cutting price costs the rep something real. In a flat commission structure, discounting is free for the rep. Realigning the incentive means introducing a penalty tier: a lower commission rate on discounted jobs, and a higher rate on full-price closes. When the financial gap between discounting and not discounting is large enough to feel, behavior changes. Usually within weeks.

What do I do with open proposals when I change the commission rate?
Notify customers that their quote expires on the stated validity date and that pricing will be updated at renewal. Most estimates carry a 21 to 30-day window — this is standard. In practice, reps who proactively resent open proposals at the new full price, with a clear note that the discounted version expires at the original deadline, found that customers bought immediately. The lesson: customers are more price-insensitive than most reps assume, especially when the rep presents the new price with confidence rather than apology.
Will my top sales reps leave if I change the commission structure?
Top performers almost never leave a restructure that raises their ceiling. A rep moving from 10% flat to 11% at full price sees it as a raise — because it is. The reps most likely to resist are those who rely on discounting to close, which is exactly the behavior you're eliminating. The restructure self-selects: strong reps who sell on value keep more. Weak reps who sell on price face a harder conversation. That conversation is worth having.
How do I raise prices in a competitive market without losing close rate?
A 3% price increase on a $5,000 job is $150. Most customers don't notice $150. What they notice is a rep who believes in the price they're presenting versus one who immediately caves. In this engagement, the close rate before the price increase was 42.21%. After: 42%. Statistically identical. Jobs were won against competitors priced $6,000 lower. Price resistance is usually rep resistance projected onto the customer. Fix the incentive structure, and the rep's confidence in the price will follow.

How much net profit should an $8M home service business be making?
A well-run home service business at $8M to $10M in revenue should be generating 15% to 25% net profit. Businesses in this range that are consistently under 10% net are almost always carrying one of three structural problems: uncontrolled discounting, a compensation plan that misaligns incentives, or overhead built for a revenue level they haven't reached yet. The first two are fixable quickly. The third requires a strategic decision about whether to grow into the overhead or cut it.
