Plumbing Technician Bonus Plan: How a Plumbing Company Built a Quarterly Plan Around a 50% Gross Margin Floor

A good plumbing technician bonus plan pays people for the money a job actually keeps, not the money it bills. That sounds obvious until you look at how a typical invoice is built. One plumbing company on Housecall Pro sat down to set up a quarterly bonus for its four technicians and hit the problem right away: material line items, including subcontractor costs, were sitting inside job revenue. On a large job those costs can run into the thousands, which means gross margin looked healthy when the job had barely broken even.

This article walks through the plan the company built to fix that: a 50% gross margin benchmark, a 20% seller and 80% performer revenue split, and a graduated bonus paid quarterly. It also covers the unglamorous rules that make a plan like this hold up, like how to treat PTO, recalls, and warranty hours.

Start With Margin, Not Revenue

Revenue-based bonuses are easy to build and easy to game. A technician who sells a big repipe with a heavy subcontractor component looks like a star on revenue and may have contributed very little margin. If the bonus pool is funded by revenue, the company pays full price for that job.

The company's answer was to recalculate every job's margin on corrected revenue. All line items in the materials section, including subcontractor costs, are deducted from job revenue first. Labor costs were already accurate, so they stayed as they were. Gross margin is then recalculated on the adjusted number, and 50% became the benchmark for bonus eligibility. When a technician's margin drops below it, the plan prompts a conversation about why instead of quietly paying out anyway.

This is the same logic behind other margin-aware plans. If you want to see how a different company protected margin without losing its team, read the pay plan that clawed back 2 points of margin.

Why Plumbing Technician Bonus Plans Work Better Quarterly

Plumbing production is lumpy. One week has three big repairs; the next is a string of small calls. A weekly bonus punishes the slow week and rewards luck. The company chose to pay quarterly on completed jobs and production hours, so the number reflects an actual stretch of work instead of a snapshot.

A quarterly cycle has a downside: people lose sight of where they stand. The company solved that by planning to show each technician their progress during the quarter, including where they sit in the graduated tiers. A bonus that only shows up at the end is a surprise. A bonus that shows up on a dashboard every week is a goal.

If you are weighing payout timing for your own company, the general guidance on tiered bonus structures is a good place to sanity-check how many tiers you need and how far apart to space them.

The Revenue Split: 20% to the Seller, 80% to the Techs Who Do the Work

Most plumbing companies have a version of this question: who gets credit when one technician sells and another performs the work? The company in this story answered with a simple split. Twenty percent of job revenue goes to the seller and the remaining eighty percent goes to the technicians performing the job. The first technician assigned to a job is treated as the seller by default.

Two details keep the split from getting messy:

• A "sold-only" tag handles the exceptions. When the technician who sold the job did not complete it, the job gets tagged and credit follows the tag. These cases are rare, and the company contact estimated them at about 5% of jobs, so the company chose to tag them instead of building complex rules around them.
• Helpers count as job costs. Helpers listed on a job are treated as a cost of that job, not as participants in the revenue split. That keeps the split between the people who earn the commission and avoids shrinking the technicians' share every time a helper rides along.

For a different take on the seller and completion split, including how a company handled a 22% pool, see how a plumbing company split a 22% pool between the seller and the techs who finish the job.

Defining Production Hours Before the First Payout

Hours are where bonus plans quietly go wrong, because everyone assumes their definition is the obvious one. The company wrote its rules down before running a single calculation, using Housecall Pro timesheet hours as the source because those hours are expected to match payroll.

• PTO and vacation hours qualify for bonus pay but do not count as production hours.
• Recall hours count toward production, because the technician is still working.
• Warranty hours do not count toward production.

Writing these rules out matters more than the specific choices. A technician who takes a week of vacation should not see their bonus collapse, and a technician who spends a week redoing someone else's warranty work should not be rewarded for producing nothing. Neither outcome is obviously right. Both are painful if you decide them after the fact.

The Materials Problem: Making Gross Margin Honest

The hardest technical piece was getting costs out of revenue without changing what customers see. Material entries, including subcontractors, are included in total revenue on the invoice, so a job with thousands of dollars in outside costs reports a margin that is far too high. The company's preferred fix was to test whether a miscellaneous cost field could hold these costs without showing up on the customer's invoice. If it does not work, the fallback is to pull the material line items directly. Either way, the rule is the same: subtract everything in the materials section before judging the job.

The company also has a backend workaround if the reporting route fails, but described it as something that would make its own process harder. That is a useful reminder when you are designing a plan. If the correct data takes extra effort to capture, the plan will be accurate only as long as someone keeps making that effort.

What the Setup Accomplished

This plan was still being built when the work was reviewed, so the results are about what got defined and verified before the first payout, not a year of paychecks. Those results are worth stating plainly:

• A single margin rule now applies to every job: subtract all material and subcontractor costs from revenue, then test the result against a 50% benchmark.
• A defined 20/80 revenue split replaces case-by-case credit decisions, with a sold-only tag for the roughly 5% of jobs that do not fit.
• Production hours are defined for PTO, recalls, and warranty work before anyone's pay depends on them.
• Payout moves to a quarterly cadence, with in-quarter visibility planned so technicians can see their tier as results build.
• The first rollout covers four technicians, with a fifth possible later, and a follow-up review scheduled to run the numbers on the current week and one or two earlier weeks.

How to Build Your Own Plumbing Technician Bonus Plan

1. Fix the revenue number first. Deduct materials and subcontractors from every job before you calculate margin.
2. Pick a margin floor and decide what happens when someone falls below it. A conversation is often better than a cliff.
3. Choose a payout cadence that matches your job mix. Lumpy work usually calls for quarterly, weekly work for weekly.
4. Write down hour rules for PTO, recalls, and warranty work.
5. Tag the rare exceptions instead of building rules for them.
6. Test on past weeks before the plan goes live so no one is surprised.

FAQ

How do you structure a bonus plan for plumbers?

Most plans pick a metric the technician can influence, such as gross margin or production hours, set a floor, and pay out in tiers above it. The company here used a 50% gross margin benchmark with a graduated quarterly payout.

Should plumbing bonuses be paid weekly or quarterly?

It depends on how lumpy your production is. Quarterly averaging smooths out big-job weeks and slow weeks, but it works best when technicians can see their progress during the quarter.

How do you split credit when one plumber sells and another performs the job?

Pick a fixed split and a tag for exceptions. Here, 20% of revenue goes to the seller and 80% to the technicians who do the work, with a sold-only tag for the rare job where the seller did not perform it.
