Which pay plan should you use for techs: hourly, flat rate, commission or hybrid?

A pay plan is the rule that turns a tech's work into a paycheck, and the plans you will choose between are built from four blocks: hourly, flat rate, commission, or a hybrid that combines a base wage with a variable layer.

The four are not interchangeable.

Each answers the same underlying question differently — whose day absorbs the risk of a slow week, a job that runs long, or a month when nothing sells.

Hourly is a fixed dollar amount per clock hour.

Your tech earns the same whether the day is packed or slow, and payroll is trivially predictable.

It is the baseline the other plans are measured against.

Flat rate — also called job rate or book rate — pays the job, not the time.

Your price book assigns each task a set of hours, and the tech earns those hours no matter how long the work actually takes.

Beat the book and the earnings per clock hour rise; run long and the tech earns no extra book hours for the overrun — though that time still counts as hours worked under the wage-and-hour rules below.

Commission pays a percentage of the revenue a tech generates — on replacement installations and maintenance-agreement sales, or on total ticket value.

Your labor cost rises and falls with sales; there is no fixed labor floor.

Hybrid is any structure that combines a base hourly wage with a variable layer — a bonus, a commission, or a spiff (a short-term incentive on one specific product) — paid against results you define.

In practice that means an hourly floor that protects quality work, plus a smaller incentive aimed at one or two measurable behaviours.

A pay plan is a set of instructions about what your shop values, and techs read it faster than any handbook.

Whatever the plan pays for — hours present, jobs closed, revenue booked, agreements attached — is what the day organizes itself around.

None of the four is neutral: each buys a behaviour, and each carries a failure mode you should know going in.

Hourly pays presence and process.

With no earnings pressure tied to speed, techs can take the time to diagnose properly, document the work and explain options to the customer — which is why hourly remains the natural fit for quality-critical diagnostic work.

The behaviour it can breed is the mirror image: paid hours with no billable work behind them.

Windshield time, bench time between calls and thin seasonal stretches are all paid by you.

Flat rate pays throughput.

A tech who consistently beats book time earns more per clock hour, which pulls the schedule tighter and rewards skill.

The failure modes are speed without accuracy — rushed diagnostics that return as callbacks — and cherry-picking, where techs compete for high-book-time, easy jobs and quietly dodge the dog work.

Your price book becomes a behavioural tool: a task priced badly will be avoided by the very techs you most want on it.

Commission pays selling.

Attach rates on maintenance agreements, replacement sales, add-on work — commission moves them; that is its job on a sales-side role.

The failure mode is overselling: when the paycheck rides on ticket size, some techs will push work a customer does not need, and the damage lands on your reviews and repeat business, not on the tech.

Hybrid pays whatever you point it at — so point it carefully.

The design intent is a stable base that keeps quality work steady, plus a variable layer aimed at one or two measurable outcomes: agreement renewals, callback rate, review scores.

If the variable layer pays on revenue alone, you have not built a hybrid; you have built a commission plan with extra steps, and you will get a commission plan's behaviour.

Match the plan to the shape of the work, not to whatever the shop down the street runs.

Three questions do most of the sorting: how predictable the job's scope is before the truck rolls, how cleanly you can measure the output, and how much of the job is actually selling.

Service and repair: the scope is unknowable until the tech diagnoses, so plans that punish diagnostic time backfire.

An hourly or hybrid base fits the diagnostic portion of service work; flat rate can work for the repair portion once your price book defines common repairs at set prices.

Flat-rating the diagnostic itself is the weak point: paid the same for a quick look as for a careful one, the tech has no earnings reason to be thorough.

Install and replacement: the scope is defined by the contract, which is what flat rate is built for — a defined job at a defined price.

Where the tech is also selling the replacement, commission or a commission-heavy hybrid fits the same logic, because the role is a sales role with a wrench in hand.

Maintenance and agreement visits: repeatable, scheduled, quality-sensitive.

Hourly keeps visit quality steady — there is little upside to rushing a tune-up and real downside if components get missed.

Where maintenance carries a commission layer, it attaches to selling the agreements themselves rather than to the visits.

A shop can therefore run more than one plan at once — hourly maintenance routes, flat-rate install crews, commission or hybrid sales roles — and a company-level mix like that is itself a hybrid strategy.

The design work is keeping each plan's pricing and compliance clean, not forcing one model across every truck.

Labor cost per billable hour — what a truck's working hour costs you against the hours you can actually charge for — is the number each plan moves differently.

No plan lowers it for free; each one relocates the risk.

Hourly: your cost is fixed per clock hour whether or not the hour produces billable work.

Payroll is predictable, but utilization drives the real cost: every paid hour of windshield time, bench time or thin schedule raises the cost of the hours that do bill.

You carry the demand risk.

Flat rate: your labor cost per job is set by the relationship you build into the plan between tech earnings and book price, and the tech carries most of the slow-day risk — fewer jobs mean fewer book hours earned — though every clock hour still counts toward the overtime math.

What you keep is pricing risk and rework: a task underpriced in your book pays the tech on a job that loses money, and a callback costs you the fix on top of a job whose revenue has already been counted.

Commission: cost rides the revenue line as a percentage — no sale, no labor cost — which is why commission structures survive thin months better than fixed payroll.

The discipline you take on in exchange is gross margin: if the plan pays on revenue rather than margin, a tech can buy a closing rate with discounts that eat the job's profit.

Hybrid: you carry a fixed floor — budget it like hourly payroll — plus a variable cost that tracks whatever metric you paid on, which you budget like commission.

The floor is the price of stability; the variable is the price of steering.

Both land in every paycheck, so both need margin room built in before you announce the plan.

The plan decides how your labor cost moves; the market decides the wage level underneath it.

Current wage data for both roles is on our HVAC technician salary page and plumber salary page.

The plan you pick does not change the wage-and-hour floor underneath it.

The Fair Labor Standards Act (FLSA), enforced by the U.S. Department of Labor, reaches every one of the four plans — the differences are in the arithmetic.

Flat rate is not overtime-free.

Flat-rate (per-job) pay does not remove the FLSA overtime duty: for job-rate and day-rate workers, the regular rate is total job pay divided by hours actually worked, plus an extra half-time for each hour over 40 in a workweek, and piece-rate workers follow the same method (29 CFR 778.111).

"Flat-rate techs aren't owed overtime" is false unless a specific exemption applies — and for an HVAC or plumbing service company, exemption is something to verify, never to assume.

Commission counts in the regular rate.

Commissions are pay for hours worked and must be included in the regular rate for overtime, whether or not they are the tech's only pay (29 CFR 778.117).

A narrow path around FLSA overtime exists for some commissioned employees — the section 7(i) exemption — and every one of its tests has to hold at once: the employer must be a "retail or service establishment," meaning one where 75% of annual dollar sales of goods or services is not for resale and is recognized as retail in that industry; the employee's regular rate must be more than 1.5 times the minimum wage; and more than half of the employee's pay over a representative period of at least one month must be commissions.

On that last point, HVAC shops should assume nothing.

In May 2020 the Department of Labor withdrew 29 CFR 779.317 — the list of businesses said to lack a "retail concept," which courts had read as specifically carving air-conditioning contractors out of the 7(i) exemption.

Whether an HVAC or plumbing service company qualifies for 7(i) now is decided case by case.

Do not build a pay plan on the assumption that commissioned techs are overtime-exempt; treat 7(i) as a question for your employment attorney, with your actual pay mix in hand.

Hybrids fold into the same math.

The base and the variable layers are one paycheck: commissions must be included in the regular rate whether or not they are the only pay, and per-job elements are regular-rated by the total-job-pay-over-hours-worked method.

Whatever the mix, the overtime calculation runs on the combined amount.

Federally funded work adds a layer.

The Davis-Bacon and Related Acts apply to contractors and subcontractors on federally funded or assisted contracts over $2,000 for construction, alteration or repair of public buildings or public works, and they require at least locally prevailing wages and fringe benefits.

On Davis-Bacon contracts over $100,000, the Contract Work Hours and Safety Standards Act also requires time-and-a-half for hours over 40 in a workweek.

Apprentice rates ride on registration: on a Davis-Bacon job, an apprentice may be paid below the journeyworker wage-determination rate only if individually registered in a program registered with the Department of Labor's Office of Apprenticeship or a recognized state apprenticeship agency, and the apprentice-to-journeyworker ratio may not exceed the ratio in that program.

Anyone paid at an apprentice rate who is not registered must get the full wage-determination rate for the work done — a rule that catches shops paying "apprentice wages" to unregistered helpers on federal jobs.

State public-works rules stack on top.

Many states run their own prevailing-wage laws — "little Davis-Bacon" acts — for state and local public works, with their own thresholds and rates.

Our research did not confirm those thresholds, and they vary by state; check your state labor department's rules before bidding public work.

Pay-plan compliance is fact-specific: the right answer depends on your pay mix, your establishments and your state. Confirm your plan's overtime treatment with an employment attorney or the Department of Labor's Wage and Hour Division before it goes live.

A pay-plan change is read as a change to the paycheck, and the surest way to lose a good tech mid-transition is a plan they cannot predict.

The switch is a communication and math problem before it is a compensation problem, and the shops that do it cleanly do the same things.

Model every tech's pay under the candidate plan using your own history — last year's jobs, actual book times, actual revenue — before you announce anything.

You need to know who gains and who loses under the new plan, because they will know within a pay period or two regardless.

Decide before the announcement how you will treat the losers: a transition adjustment, a phase-in schedule, or an honest conversation about why the role is changing.

Deciding after the first angry paycheck is deciding in the worst frame possible.

Explain the why in operational terms: what the change fixes — callback costs, idle hours, uneven workloads, agreement attach rates — and what it deliberately does not touch.

Put the mechanics in writing: how hours are recorded, how book times are set and reviewed, when variable pay is calculated and paid, and how overtime is computed under the new plan.

The regular-rate rules in the section above apply to the new plan from its first day, and retroactive overtime exposure is the most expensive way to learn that math.

Where you can, pilot the plan on a single crew for a defined period and fix the price book and the calculations before it goes shop-wide.

Then set the review date when you announce the plan: book times drift out of date, product mixes change, and a pay plan is a living document, not a one-time decision.

A plan techs can predict is a plan they will stay on.
