Most plumbing business owners manage by gut feeling.
They know roughly how many jobs ran this week. They have a sense of whether revenue was up or down. They feel like the business is doing okay — or not.
That's not management. That's hope with a truck payment.
The plumbing companies that consistently grow — the ones that hit $3M, $5M, $10M and beyond — are run by owners who track specific numbers every single week and make decisions based on data, not feelings.
I've built and coached plumbing businesses to seven figures, and I can tell you with certainty: the difference between a business that scales and one that stalls is almost always the owner's relationship with their numbers.
Here are the 12 KPIs that matter most, what they should look like, and how to use them to run a better business.
Key Takeaways
- Call booking rate should be 85%+ — below 75% means you're leaving significant revenue on the table every week
- Average ticket is the fastest lever to pull for immediate revenue growth without adding a single new call
- Revenue per technician per day is the single most important productivity metric in a service plumbing company
- Maintenance agreement penetration rate is the key to predictable recurring revenue
- Track KPIs weekly, not monthly — monthly reviews are too slow to prevent problems from compounding
Why Weekly KPI Tracking Changes Everything
There's a principle in behavioral science called feedback loops — the idea that behavior changes fastest when the feedback is immediate, specific, and tied to a clear standard.
When your technicians know their average ticket is tracked weekly and reviewed in the Monday morning huddle, their behavior changes. When your CSRs know their booking rate is measured daily, they answer the phone differently.
Monthly reviews don't create this effect. By the time you see a problem in a monthly report, you've already lost 30 days of revenue and momentum. Weekly tracking creates a culture of accountability that monthly tracking simply cannot.
The 12 KPIs Every Plumbing Business Owner Must Track
1. Call Volume (Inbound Calls Per Week)
Call volume is the top of your revenue funnel. Every other metric downstream depends on calls coming in.
Track total inbound calls per week, broken out by source if possible (LSA, organic, referral, repeat customer). If call volume drops, you have a marketing problem. If call volume is strong but revenue is weak, the problem is downstream — booking rate, average ticket, or conversion.
Benchmark: Set a weekly call volume target based on your revenue goal. A company targeting $2M in revenue with a $450 average ticket and 85% booking rate needs approximately 100–110 booked calls per week.
2. Call Booking Rate
Booking rate is the percentage of inbound calls that result in a scheduled appointment. This is one of the most undertracked metrics in the plumbing industry, and one of the most impactful.
If your CSR answers 100 calls and books 72 appointments, your booking rate is 72%. That means 28 potential customers called, got a live person, and still didn't book — which means you paid for the marketing to generate that call and got nothing for it.
Benchmark: 85%+ is the target. Below 75% is a serious problem. Top-performing plumbing companies run 88–92% booking rates with well-trained CSRs and a structured call script.
For a complete breakdown of how to improve this number, read our guide on plumbing CSR and dispatcher training.
3. Average Ticket
Average ticket is total revenue divided by number of jobs completed. It's the single fastest lever to pull for immediate revenue growth — because it doesn't require a single additional marketing dollar or a single additional call.
If you have 10 techs running 5 jobs each per day and your average ticket goes from $350 to $450, that's an extra $5,000 per day in revenue — $1.25M per year — without changing anything else.
Benchmark: $400–$600 for residential service plumbing. Below $350 usually means techs aren't presenting options, aren't doing thorough diagnostics, or are discounting too aggressively.
See our full guide on how to increase plumbing technician average ticket for the specific strategies that move this number.
4. Revenue Per Technician Per Day
This is the master productivity metric for a service plumbing company. It combines average ticket, jobs per day, and utilization into a single number that tells you how efficiently your field team is converting time into revenue.
Benchmark: $1,200–$1,800 per tech per day for residential service plumbing. Below $1,000 is a red flag. Above $1,500 consistently means you have a high-performing team and strong systems.
Track this by individual technician, not just company average. A company average of $1,300/day might be masking one tech at $1,800 and another at $800 — and those two techs need very different conversations.
5. Jobs Per Technician Per Day
Jobs per day measures how many appointments each technician is completing. The target varies by service type — drain cleaning runs higher (4–6 jobs/day) than water heater installs (1–2 jobs/day).
If jobs per day is low, the problem is usually dispatch (too much drive time between jobs), job duration (techs taking too long), or call-backs (returning to fix work that wasn't done right the first time).
Benchmark: 3–5 jobs per tech per day for mixed residential service work.
6. Conversion Rate (Presented vs. Sold)
Conversion rate is the percentage of service calls where the technician presents an option and the customer approves the work. This is different from booking rate — booking rate is about getting the appointment, conversion rate is about closing the job once you're there.
A low conversion rate usually means techs aren't presenting options confidently, aren't using a price book, or are pre-judging customers and not presenting the full scope of work.
Benchmark: 65–80% conversion rate on presented options. Below 55% is a training and process problem.
7. Gross Margin % (Weekly)
As covered in our P&L guide, gross margin is the percentage of revenue left after paying for direct labor and materials. Track this weekly, not monthly.
Benchmark: 55–65% gross margin. A sudden drop week over week is a signal to investigate immediately — don't wait for the monthly P&L.
8. Maintenance Agreement Penetration Rate
Maintenance agreement penetration is the percentage of service call customers who are enrolled in a maintenance plan. This is the key to building predictable recurring revenue in a plumbing business.
Customers on maintenance agreements call back more often, spend more per visit, and refer more friends. The data from ServiceTitan consistently shows that maintenance agreement customers have 2–3x the lifetime value of one-time service customers.
Benchmark: 15–25% of active customers on a maintenance plan. Top performers run 30%+.
9. Customer Satisfaction Score (CSat) / Review Rate
Track the percentage of completed jobs that result in a 5-star Google review request being sent, and the percentage that actually leave a review. Your online reputation is a direct driver of inbound call volume through Local Services Ads and organic search.
Benchmark: Send a review request on 100% of completed jobs. Target a 15–25% review conversion rate (15–25 reviews per 100 requests sent).

10. Call-Back Rate
Call-back rate is the percentage of completed jobs that require a return visit to fix a problem with the original work. This is a quality and training metric, not just a customer service metric.
Every call-back costs you a truck roll, a technician's time, and often a customer relationship. At a $200 average cost per call-back, a company with a 5% call-back rate on 1,000 jobs per month is burning $10,000/month in rework.
Benchmark: Below 3% call-back rate. Above 5% requires immediate investigation into training, parts quality, or diagnostic processes.
11. Lead Time (Days to Next Available Appointment)
Lead time is how many days out your next available appointment is. This is a capacity and demand metric that tells you whether you're understaffed, overstaffed, or just right.
If lead time is consistently above 3–4 days, you're losing customers to competitors who can get there faster. If lead time is 0 days (same-day availability always), you may be overstaffed or under-marketed.
Benchmark: 1–2 days for non-emergency work. Same-day or next-day for emergency calls.
12. Revenue Per Marketing Dollar (ROAS)
Return on ad spend (ROAS) measures how much revenue you generate for every dollar spent on marketing. This is the metric that tells you whether your marketing is working or whether you're just burning money.
Track ROAS by channel — Google LSA, Google Ads, Facebook, direct mail, etc. — so you know where to invest more and where to cut.
Benchmark: 5:1 ROAS minimum (5 dollars of revenue for every 1 dollar of marketing spend). Top-performing plumbing companies run 8:1 to 12:1 on their best channels.

How to Build Your Weekly KPI Scorecard
A KPI scorecard is a one-page document that shows all 12 metrics side by side: this week's actual, last week's actual, week-over-week change, goal, and YTD average.
Review it every Monday morning in your team huddle. Post it where your team can see it. Celebrate wins. Address gaps immediately.
The scorecard creates accountability without micromanagement. When a technician sees their revenue per day on a shared board, they self-correct. When a CSR sees their booking rate is 71% while the team average is 87%, they ask for coaching. The data does the managing for you.
Tools like ServiceTitan, Housecall Pro, and JobNimbus can generate most of these metrics automatically. The key is to pull them into a single view so you're looking at the whole picture, not just one number at a time.

Frequently Asked Questions
What KPIs should a plumbing business track?
The most important KPIs for a plumbing business are call booking rate, average ticket, revenue per technician per day, gross margin %, conversion rate, maintenance agreement penetration, call-back rate, and ROAS by marketing channel. Track these weekly, not monthly, for maximum impact on business performance.
What is a good booking rate for a plumbing company?
A good call booking rate for a plumbing company is 85% or higher. This means that out of every 100 inbound calls, at least 85 result in a scheduled appointment. Below 75% indicates a significant CSR training or process problem that is costing you revenue on every marketing dollar you spend.
What is a good average ticket for a plumbing company?
A good average ticket for residential service plumbing is $400–$600 per job. Below $350 typically means technicians aren't presenting full options or are discounting too aggressively. Above $600 consistently usually indicates strong diagnostic skills, good option presentation, and effective use of a flat rate price book.
How do I track KPIs for my plumbing business?
The most efficient way to track plumbing business KPIs is through your field service management software (ServiceTitan, Housecall Pro, etc.) combined with a simple weekly scorecard. Pull the key metrics every Friday, populate your scorecard, and review it every Monday morning with your team. The review process itself — not just the tracking — is what drives performance improvement.
What is revenue per technician per day for a plumbing company?
Revenue per technician per day is total revenue divided by the number of technician days worked. For residential service plumbing, the benchmark is $1,200–$1,800 per tech per day. Below $1,000 indicates a pricing, productivity, or scheduling problem. Track this by individual technician to identify your top performers and those who need coaching.
The Bottom Line on Plumbing Business KPIs
You can't manage what you don't measure. And you can't grow what you don't manage.
The 12 KPIs in this guide are not complicated. They don't require a finance degree or expensive software. They require discipline — the discipline to pull the numbers every week, review them with your team, and make decisions based on data instead of gut feeling.
The plumbing owners who build businesses worth selling — who create real wealth and real freedom — are the ones who treat their business like a business, not a job. That starts with knowing your numbers.
