Estimator commission structure that works: 0.5% per role, a 20% margin floor, and why project-level profit caught a job showing -140% margin before payout.
An estimator commission structure sounds like the easy part of a sales plan. Estimators price the work, project managers deliver it, and each gets a small percentage for their piece. The trouble starts when the number you are taking a percentage of is wrong. One commercial service and installation company working through its plan on ServiceTitan found a job that showed an $11,000 invoice and a margin of negative 140%. The job was not a disaster. The revenue had been billed separately from the labor and material costs, so the job-level math was meaningless.
That single job changed how the company thinks about commissions. This article covers the structure it built: 0.5% for estimators, 0.5% for project managers, 1% for anyone who fills both roles, a gross margin floor, and a rule for when to calculate commission on the project instead of the individual job. It also covers why the company chose to run the calculations for a few weeks before paying technicians a cent.
The Base Estimator Commission Structure: 0.5% Per Role
The company's starting point was simple and easy to explain. Project managers earn 0.5%. Estimators earn 0.5%. When one person is listed in both roles on a project, they earn 1% total, which is the same as if two people had split the work.
That shape matches what shows up in construction pay research, where estimators who price winning bids and project managers who secure add-ons often earn a flat bonus or a small shared commission somewhere between 0.5 and 1 percent. The company's version has two features that make it easier to run than most:
- The rate attaches to a role, not a person. Rates stay stable when the team changes, and nobody has a private deal that surprises the next hire.
- Dual-role pay is additive, not negotiated. Someone who estimates and manages the project gets both pieces. No special case, no argument.
For comparison, a different approach to unifying inconsistent plans shows up in this account of how an 18-person electrical contractor unified five pay plans into one standard. The common thread is the same: a plan is easier to trust when a stranger can read it in a minute.
Classifying Jobs So the Right Rate Applies
Commission rules only work if the system knows what kind of job it is looking at. The company mapped its job types into three groups:
- Service: repair, maintenance, emergencies, deliveries, and parts pickup.
- Install: installation, replacement, and new construction.
- Door slabs: a separate job type, because the economics differ from both of the above.
The practical trick is naming. The company standardized on job type names that contain the word "service" or "install," so a new job type created next year gets classified by the commission logic without anyone rewriting the plan. It is a tiny habit that prevents a lot of future cleanup.
Job-Level Margin vs Project-Level Margin
This is where the estimator commission structure nearly went sideways. The plan pays against gross profit, and gross profit is only as good as the data behind it. On a project with multiple bill-outs, costs hit the job as work happens while revenue is billed in pieces. Look at any single job in the middle of that process and the margin can be absurd, like that $11,000 job at negative 140%.
The fix is a rule, not a formula: for projects with partial bill-outs, calculate commission on project-level gross profit, and for standalone jobs, use job-level gross profit. Deciding which is which still needs a reliable report, and the company was working that out when the review happened. Two other data issues surfaced at the same time:
- Jobs marked complete too early. Completion date is the commission trigger because most of the work is commercial and completion usually matches the invoice date. That only works if completion means complete. During the review, the team found a job marked complete that still had a balance remaining, and corrected it on the spot.
- Jobs attached to the wrong projects. ServiceTitan reporting showed jobs associated with projects they did not belong to, which would push commission to the wrong place.
The commission basis also changed slightly during the review: calculations now use the job subtotal rather than the tax-inclusive total, so tax never inflates anyone's payout. A margin-based plan from a different trade shows the same discipline; see the margin-based commission plan that closed a $500 monthly bonus gap.
A Gross Margin Floor Protects the Company
The plan includes a gross margin payout floor of 20%. Commission is only earned when a job clears it. Management asked whether the floor could later move to 30% and agreed to keep 20% for now after learning that raising it later would be a quick change. That is a good model for any floor: start where the data is trustworthy, and tighten it once the numbers have proven themselves.

Why Validate Before You Pay Technicians
A commission plan is a promise, and a promise built on unchecked data is a promise you may have to break.
The company is also considering pay for technician sales, including a possible 1% to 2% on sold estimates and separate pay for tracked add-ons. The key decision was about timing, not rate. Rather than roll out technician commissions immediately, the company decided to monitor the calculations for at least a couple of weeks, ideally a month, before paying anyone. If a calculation turns out to be wrong, catch-up payments can be made afterward.
It is easy to see why. Paying an incorrect amount and then correcting it a week later costs more trust than waiting. A month of shadow calculations also gives employees time to compare Sharewillow's numbers with their own tracking, which is exactly what the company's management wanted. Before this, one manager was recording completed projects by hand each month to track commissions, which is slow, easy to get wrong, and impossible for employees to audit on their own.
There is another data problem to solve before technician add-on pay works: sold-by assignments on invoice line items are not used consistently, so upsells are hard to identify. The fix is training. The team agreed to get familiar with recording add-ons and the sold-by person correctly before the technician plan goes live.

What the Review Produced
The company was still validating when this was written, so the results are about problems caught before payout, not a year-end total:
- A role-based rate card is set: 0.5% for estimators, 0.5% for project managers, and 1% for someone holding both.
- Job types are grouped into service, install, and door slab, with naming that classifies new job types automatically.
- A job showing $11,000 at negative 140% margin exposed why project-level profit is needed for partial bill-outs.
- A prematurely completed job was found and corrected before it could trigger a commission.
- Employees can drill into their own commission detail by job number and compare it with their own tracking.
- A 2 to 4 week validation window is set before technician sales commissions start.
How to Set Up Your Own Estimator and Project Manager Commissions
- Attach rates to roles. Keep dual-role pay additive.
- Standardize job type names so classification can be automatic.
- Decide when project-level profit applies and write it down before the first payout.
- Use completion as the trigger only if completion is trustworthy. Audit for jobs marked complete with a balance remaining.
- Calculate on subtotal, not on the tax-inclusive total.
- Set a margin floor you can defend, and revisit it once you trust the data.
- Run shadow calculations for a few weeks before real money moves.

FAQ
What is a typical commission for a construction estimator?
Many companies pay estimators a small share, often somewhere between 0.5% and 1% of the sale or gross profit, or a flat bonus per won bid. This company pays 0.5% to the estimator and 0.5% to the project manager.
Should commission be based on revenue or gross profit?
Gross profit protects margin. Revenue-based commission pays full price for a job that barely made money. If you use gross profit, make sure costs and revenue are matched on the same job or project, or the percentage will be calculated on a misleading number.
How do you pay commission on a project billed in several pieces?
Use project-level gross profit instead of job-level. Looking at one job in the middle of a partial bill-out can show wildly negative or positive margins that disappear once every bill-out and cost is combined.
