Latest / Scaling Up with Fexingo: How Small Businesses Become Mid-Market Companies / The One Metric That Broke a Five Million Dollar Plumber
Transcript
- Lucas: Five million dollars in revenue. That's the ceiling a lot of service businesses hit—plumbers, electricians, HVAC companies. They get to that number, and suddenly every new dollar costs more than the last one. Today I want to look at one plumbing company in Phoenix that ran into that exact wall, and how the owner broke through it by tracking a single metric most plumbers ignore. Luna: I'm guessing it's not trucks or leads, because every service business chases those first. Lucas: Exactly. This guy—his name is Dave—he grew from a solo truck to about fifteen vans. Revenue plateaued near $5 million for almost two years. He tried more advertising, tried buying another small shop, none of it moved the needle. Then he started measuring what he called 'first-visit completion rate.' How many jobs get fully resolved on the very first trip to the customer's house. Luna: Quick honest thing—this episode, like all three hundred shows on this network, stays ad-free because a handful of listeners chip in monthly through buy me a coffee dot com slash fexingo. If these conversations have moved your work forward in some small way, that link is there. It's what keeps us doing this many episodes without any sponsors. Now back to Dave's plumbing company. Lucas: So Dave went back through his records. He found that his first-visit completion rate was hovering around 62 percent. That means almost four out of ten jobs required a return trip—maybe they didn't bring the right part, maybe the tech misdiagnosed the issue, maybe the truck wasn't stocked properly. Every return trip eats a profit margin that's already thin. Luna: And each return trip is also a brand hit. Nobody likes waiting an extra day for a plumber. Lucas: Right. So Dave didn't just look at the number. He looked at the causes. He built a simple log: every time a tech couldn't finish on the first visit, they checked one of five boxes—wrong part, wrong diagnosis, wrong tool, need a permit, or need a second person. After three months, the pattern was clear. Wrong part and wrong diagnosis accounted for 70 percent of the failures. Luna: So the fix wasn't dispatch. It was inventory and training. Lucas: Exactly. Dave redesigned his truck stocking system. Previously, every van carried the same standard package—fittings, a few valves, basic pipe. But his jobs fell into three categories: residential service, new construction rough-in, and commercial repair. Each category needed different parts. He created three different truck loadouts. Techs were assigned based on their primary job type, and the inventory manager restocked by category, not by van number. Luna: How long did that take to implement? Lucas: About six weeks to get the new inventory system in place. But the bigger lever was training. Dave started doing a weekly thirty-minute case review where the techs would walk through the last job they couldn't finish. No blame—just 'what did you think the problem was, what did you find when you got back, and what would you do differently.' He said the first few sessions were awkward, but after a month, techs started self-correcting. Luna: There's a humility piece there. Most owners would rather buy a new software tool than sit in a room and admit they're guessing wrong. Lucas: Yeah, and Dave almost bought a $50,000 dispatch optimization platform before he realized the issue wasn't routing—it was knowledge. After six months, his first-visit completion rate went from 62 percent to 78 percent. That sixteen-point improvement had a direct impact on revenue because each truck could handle more jobs per day. They didn't add a single van. They just got better at finishing the first time. Luna: And the $5 million ceiling? Lucas: They crossed $7 million within twelve months. By eighteen months, they were at $10 million. Same fleet size. Dave told me the single biggest change was the weekly case review—because it forced the whole team to think about root cause instead of just 'go fix it.' He also added a simple part: if a tech couldn't finish, they had to call the office before leaving the customer's house. The dispatcher would then cross-reference the symptom with a checklist the team had built together. Luna: So the call became a real-time coaching moment instead of a failure log. Lucas: Exactly. The dispatcher wasn't a technician—she was trained to ask the three questions from the checklist. 'Did you check the pressure? Is the shutoff fully open? Did you try resetting the unit?' It sounds basic, but those questions caught another 5 percent of issues that could have been solved without a return trip. The techs started respecting the checklist because it worked. Luna: I wonder how much of this applies to other trades. The specific problems are different, but the pattern—measure completion, find the bottleneck, fix the knowledge gap—feels universal. Lucas: I think it's universal. I talked to an HVAC company in Ohio that tried the same approach. Their first-visit completion rate was 55 percent. They got to 72 percent in five months. Their revenue didn't double like Dave's, but it grew 30 percent without adding a truck. And their net profit margin went from 8 percent to 14 percent because return trips are incredibly expensive—they're essentially paying a tech twice for the same job. Luna: What about the customer experience? The reviews probably improved too. Lucas: Dave said his online rating went from 4.2 to 4.7 stars. And the number of repeat service agreements—annual maintenance plans—went up because customers who had a good first visit were more likely to sign a contract. That's a recurring revenue stream that compounds. So the metric didn't just fix the immediate problem; it created a flywheel. Luna: So if someone listening runs a service business, what's the one thing they should do tomorrow? Lucas: Start tracking first-visit completion rate manually if you have to. Pull the last thirty jobs. Count how many required a second trip. Then for each failure, write down the one reason. Don't try to fix everything at once—just look for the reason that shows up most often. In Dave's case, it was parts. In the HVAC company, it was misdiagnosis. That one reason is your leverage point. Fix that, and you'll see movement faster than any other change you could make. Luna: And if the number is already high, say above 85 percent, then your bottleneck is probably somewhere else—maybe lead generation or sales conversion. Lucas: Right. Dave's next metric after hitting 85 percent completion was 'job value per truck per day.' But he told me he wouldn't have gotten there without first solving the return-trip problem. It's the foundation. Most service businesses try to build growth on a weak foundation—too many second visits, too much rework. Fix that first, and everything else gets easier. Luna: I like that. The boring metric that unlocks everything. Lucas: Exactly. And it's free to track. You don't need software. You just need a whiteboard and an owner who's willing to ask why the truck came back.
