Top 10 KPIs for Plumbing Contractors in 2027

1. Plumbing Contractor Average Residential Ticket

Average residential ticket ranks first because it is the single number that moves fastest with price-book discipline and option presentation, and it compounds across every call a technician runs. Total residential service revenue divided by completed revenue-producing calls, excluding new construction, commercial work, and diagnostic-only trips. A $40 lift across six calls a day, five days a week, is a five-figure annual swing per truck.

It is for residential service shops with a written price book and technicians trained to present tiered repair, replace, and upgrade options. It trades away simplicity: you must split diagnostic-only trips into a separate line or the denominator silently deflates the average. Compared with trip-fee capture directly below, ticket needs a full quarter of coaching before it moves, while fee enforcement shows results in weeks.

2. Plumbing Contractor Trip-Fee Capture Rate

Trip-fee capture ranks second because it is the most controllable number on the scorecard and the fastest to pay. Dispatch or diagnostic fees actually collected divided by dispatches where a fee was owed. A nine-truck shop running 30 to 40 after-hours dispatches monthly and waiving a third at $150 to $250 each leaks $18,000 to $40,000 in pure margin annually.

It suits any shop where technicians currently waive the fee at their own discretion, and it needs no new software. It trades away goodwill in rare cases where a customer walks over the fee, which is why a low manager-approved waiver rate beats zero waivers. Compared with average residential ticket above, it changes behavior within four to six weeks rather than a quarter.

3. Plumbing Contractor Billable Hour Utilization

Billable hour utilization ranks third because it measures whether the shop's largest fixed cost, paid technician time, converts into revenue at all. Invoiced labor hours divided by total paid technician hours, with drive time, shop time, warehouse pulls, paid training, and warranty callbacks excluded from the numerator. A five-point gain on a full-time technician converts roughly 200 previously unbilled hours into billable ones.

It is for owners and dispatchers, not technicians, since routing and schedule density drive it. It trades away the flattering number most shops report: counting drive time as billable inflates utilization by ten to fifteen points and hides the routing inefficiency causing soft margin. Compared with revenue per technician below, utilization answers whether work is happening, while revenue per technician answers how much each truck produces.

4. Plumbing Contractor Revenue Per Technician

Revenue per technician ranks fourth because it rolls utilization, ticket, and mix into one field-labor productivity figure. Annual residential service revenue divided by full-time-equivalent field technicians, excluding dispatchers, warehouse staff, office personnel, and the owner. Apprentices and helpers count only at the share of the week they run calls solo, and the rule must be written down and held constant.

It is for owners benchmarking trucks against each other and against published trade surveys. It trades away diagnostic precision: a decline tells you something is wrong but not whether the cause is idle technicians or small tickets. Compared with billable hour utilization above, it is the outcome measure, and utilization is the upstream lever you pull to move it.

5. Plumbing Contractor Service Gross Margin

Service gross margin ranks fifth because it is the number lenders and buyers underwrite, and it exposes whether pricing covers the real cost of delivery. Service revenue minus direct labor, materials, consumables, and allocated truck cost, divided by service revenue. Technician burden including payroll taxes, benefits, and workers' compensation belongs above the line, and truck cost belongs in the calculation.

It is for shops preparing for financing, acquisition, or a serious margin conversation. It trades away the comfort of a wage-only margin, which flatters itself by a wide margin and collapses under lender scrutiny. Compared with revenue per technician above, margin describes the quality of the revenue while revenue per technician describes its quantity, and the two must be read together.

6. Plumbing Contractor Membership Attach Rate

Membership attach rate ranks sixth because members call their own plumber first, lowering acquisition cost on every future cycle and scheduling visits into slack capacity. New paid memberships enrolled divided by eligible completed calls to non-members, kept strictly separate from retention. The offer belongs early in the call, before the pricing conversation, while the customer is still evaluating the relationship.

It is for residential shops with a real membership program and a delivered annual inspection. It trades away some current-call ticket attention, since the enrollment conversation consumes time that could go to option presentation. Compared with service gross margin above, attach is a field sales metric, while margin is an operations outcome that lags it by a quarter.

7. Plumbing Contractor First-Time Fix Rate

First-time fix rate ranks seventh because callbacks cost twice: they consume a slot that could have sold new work and arrive as unbillable warranty time. Calls resolved on the first visit with no return trip for the same issue within 30 days. A deferred quote is not a first-time fix, because the customer's problem is still there when the technician leaves.

It is for shops whose technicians are pushed to pack the board, since eight calls against an honest capacity of six invites cut corners. It trades away short-term utilization gains, because the callbacks land two weeks later and erase them. Compared with membership attach rate above, first-time fix is the defensive floor that keeps an aggressive ticket push from splitting jobs into return visits.

8. Plumbing Contractor Booked-To-Sold Conversion

Booked-to-sold conversion ranks eighth because it isolates the on-site presentation, which is where most shops actually lose work. Completed paid jobs divided by dispatched appointments, measured at the technician-on-site layer rather than the phone layer. The phone layer already has its own metric, call-to-book, and conflating the two hides where the loss occurs.

It is for field supervisors coaching technicians on option presentation and pricing conversations. It trades away the reassuring blend that makes booking and selling look like one number, which is precisely the blend that prevents diagnosis. Compared with first-time fix rate above, conversion measures whether work was sold at all, while first-time fix measures whether the sold work was finished correctly.

9. Plumbing Contractor Drain And Water-Heater Mix

Drain and water-heater revenue mix ranks ninth because these two categories carry the highest tickets and the clearest upgrade paths in residential plumbing. Combined drain work including cabling, hydro-jetting, camera inspection, and sewer repair plus water-heater repair, tank replacement, and tankless conversion, as a share of total service revenue. Watching the mix reveals drift toward low-value break-fix volume while call counts still look healthy.

It is for shops whose revenue per truck is flat despite steady call volume. It trades away the simplicity of a single blended average, which hides whether the shop is winning profitable work or just staying busy. Compared with booked-to-sold conversion above, mix describes what was sold, and conversion describes whether anything was sold at all.

10. Plumbing Contractor Call-To-Book Conversion

Call-to-book conversion ranks tenth because it is the only metric in the stack that lives entirely off the truck, and it caps everything downstream. Inbound calls that become scheduled appointments, driven by scripting, hold times, and after-hours answering. When it is weak, the problem is the call center, not technician performance, and no amount of field coaching will fix it.

It is for shops with a dedicated dispatcher or answering service handling search, referral, past-customer, and membership-renewal calls. It trades away nothing operationally but demands separate ownership from booked-to-sold conversion, since blending the two hides whether the loss happened on the phone or in the driveway. Compared with booked-to-sold conversion above, it is the upstream gate that determines how many appointments exist to sell into.

How we ranked these

Each metric was scored on three weighted factors: how directly it maps to cash margin, how quickly a manager can act on it, and whether it can be measured per technician without shared-cost allocation guesswork. Trip-fee capture, billable utilization, average residential ticket, and booked-to-sold conversion carried the heaviest weight because they move within a week and sit under a named person's control.

Deliberately excluded: blended commercial-plus-residential margin, quoted rather than billed revenue, and any metric requiring allocated overhead to compute. Those hide the operating problem inside accounting noise and cannot be coached. Also ignored were vanity call-volume rankings and single-number technician scorecards, since both reward behavior that damages callbacks and margin over a full season.

What to look for

What matters is whether the tool splits residential from commercial at the source, tracks trip-fee waivers by technician name, and reports billable utilization with drive time excluded from the numerator. If it cannot separate membership attach from membership retention, or cannot show first-time fix rate on a thirty-day window, it will produce numbers nobody can act on.

The mistake most buyers make is choosing software by dashboard aesthetics and integration count, then discovering the platform blends job types and counts quoted revenue as booked. Ask for a live demo using your own last quarter of job data. If the utilization figure looks ten points better than your gut says, the definition is wrong, not your gut.

Related questions

What is a good billable hour utilization rate for a plumbing contractor?

Most residential shops land between 55% and 70% when drive time, shop time, and training are correctly excluded from the numerator. Anything reported above 80% almost always means drive time got counted as billable. Run it per technician weekly, and treat a wide spread between your best and worst technician as a routing problem rather than a sales problem.

How should trip-fee capture rate be calculated?

Divide dispatch or diagnostic fees actually collected by dispatches where a fee was owed. Track waivers by technician name, not as a shop-wide average, because the behavior is individual and discretionary. A 3% waiver ceiling, published weekly on a visible board, typically closes most of the gap within one quarter without any change to pricing or policy language.

Why separate membership attach rate from membership retention?

Attach is new paid memberships divided by eligible completed calls to non-members, and it is a field sales metric. Retention is renewals divided by memberships up for renewal, and it is an operations metric owned by whoever delivers the included annual visit. Blending them hides whether you have a selling problem or a delivery problem, and the two require completely different fixes.

What counts as a first-time fix in plumbing service?

A call resolved on the first visit with no return trip for the same issue within a defined window, commonly thirty days. A deferred quote does not count, because the customer's problem still exists. Callbacks cost twice: they consume a slot that could have sold new work, and they arrive as unbillable warranty time that quietly destroys the utilization gain you were chasing.

How do I benchmark my plumbing shop against published industry data?

Use published benchmarks for direction and spread, not absolute targets. Association surveys skew toward well-run member shops, software-vendor reports skew toward platform users, and franchise disclosures reflect royalty-paying locations with prescribed price books. Your own top-quartile versus bottom-quartile technician gap, measured on identical pricing and territory, is a far more trustworthy number.

Should commercial and residential plumbing metrics be reported together?

No. Commercial work runs at meaningfully lower gross margin and carries receivables measured in weeks rather than collected at the door. Residential service is priced at the truck and paid on completion. One blended margin line tells you nothing actionable about either business, so split them with a job-type flag at the source in your field-service system.

What is the fastest KPI to improve in a plumbing business?

Trip-fee capture rate. It requires no new leads, no pricing change, and no capital, only visibility. Publishing waiver counts by technician name weekly usually closes most of the gap in a quarter. The annual leakage from waived after-hours dispatch fees alone commonly runs between $18,000 and $40,000 in pure margin for a nine-truck shop.

How often should plumbing KPIs be reviewed?

Weekly for anything a technician or dispatcher controls directly: trip-fee capture, booked-to-sold conversion, membership attach, and utilization. Trend ticket and gross margin over thirteen weeks rather than month to month, because a single large replacement job distorts a short window. Review the full stack monthly with a revenue floor attached so margin targets do not reward shrinking the business.

FAQ

What are the best KPIs for plumbing contractors in 2027?

Average residential ticket, billable hour utilization, revenue per technician, trip-fee capture rate, membership attach rate, service gross margin, drain and water-heater revenue mix, first-time fix rate, and booked-to-sold conversion. Track them weekly, keep commercial separate from residential, and tie technician pay to a balanced set rather than one headline number that rewards the wrong behavior.

Why can't plumbing contractors use a generic SaaS dashboard?

Subscription dashboards are built around recurring revenue, customer acquisition cost, and net revenue retention, where delivery cost is near zero after the first sale. A plumbing contractor's delivery cost is a truck, a technician, fuel, parts, and a finite number of daylight hours. Every meaningful metric is really a question about revenue produced per available technician hour, at what margin.

What is a healthy average residential ticket for a plumbing company?

There is no universal figure, because job mix drives it more than pricing does. The useful measurement is your own thirteen-week trend plus the gap between your top and bottom technician on identical job mix. A $40 increase in average ticket across six calls a day, five days a week, is a five-figure annual swing per truck using your own rates.

How do I calculate revenue per technician correctly?

Annual residential service revenue divided by full-time-equivalent field technicians. Exclude dispatchers, warehouse staff, office personnel, and the owner, because this metric measures revenue-producing field labor only. Apprentices and helpers are a judgment call; count them at partial FTE matching the share of jobs they run solo, write the rule down, and never change it mid-year.

What should service gross margin include?

Service revenue minus direct labor, materials, consumables, and allocated truck cost, divided by service revenue. Include technician burden such as payroll taxes, benefits, and workers' compensation, and include vehicle cost. A margin computed on bare hourly wage with no truck cost flatters itself by a wide margin and will not survive scrutiny from a lender or a buyer.

Why is drain and water-heater revenue mix worth tracking?

Those two categories generally carry the highest tickets and the clearest upgrade paths in residential plumbing, from cabling to hydro-jetting to camera inspection to sewer repair, and from tank repair to replacement to tankless conversion. Watching the mix tells you whether the shop is winning profitable work or drifting into low-value break-fix volume while call counts still look healthy.

What is booked-to-sold conversion and where should it be measured?

Completed paid jobs divided by dispatched appointments, measured at the technician-on-site layer rather than the phone layer. The phone layer already has its own metric, call-to-book. Conflating the two hides where the loss occurs, which for most shops is the on-site presentation of options, not the booking call that preceded it.

How do I stop technicians from waiving the dispatch fee?

Publish waiver counts by technician name weekly. Visibility alone typically fixes most of the behavior within a quarter because it becomes observable. For the remainder, require manager approval rather than issuing another policy memo. A rigid zero-waiver rule is not the goal; a low, visible, manager-approved waiver rate is.

Which plumbing KPIs pull against each other?

Ticket versus first-time fix, utilization versus first-time fix, trip-fee capture versus conversion, and margin versus growth. Pushing any one in isolation damages another. Score technicians on a balanced set, typically ticket, callback rate, trip-fee capture, and membership attach together, with a floor on defensive metrics rather than a bonus on one offensive number alone.

What is the most common reporting mistake in plumbing KPIs?

Counting drive time as billable. It makes utilization look excellent while gross margin stays stubbornly low, and it hides the routing inefficiency that is the actual problem. Drive time, shop time, warehouse pulls, and paid training all belong in overhead. If your utilization number drops sharply when you fix the definition, that drop is information, not failure.
