How to hire a service manager: sourcing, screening and what to offer

A service manager runs your service operation: they schedule and assign the work, supervise the techs and advisors doing it, inspect completed jobs, review performance and make the hire, promotion and discipline recommendations that shape your bench. Before you post anything, write down which pieces of that the seat owns at your shop — the job looks different in a dealer service department, an independent garage and a quick lube.

The closest federal occupation profile is O*NET's First-Line Supervisors of Mechanics, Installers, and Repairers (49-1011). Its task list reads like the job description you should be writing: supervising and coordinating mechanics and repairers, inspecting completed work, and setting schedules and assignments based on work priority and the skill of the crew. The list goes on through monitoring work levels, reviewing performance, and recommending hires, promotions, discharges or discipline.

"Service Manager" is one of that occupation's sample job titles, and the code spans every repair trade — not just auto.

Then translate the profile into your building with numbers you can defend. NADA's 2025 data put the average franchised dealership at 16 technicians (including the body shop), 16,252 repair orders written and $9.69 million in service and parts sales. Compare that ratio to your own: divide your shop's annual repair orders by the technicians writing them, and you have the per-technician volume this seat supervises at whatever scale your bays run.

Smaller operations run a different shape, and the averages above are dealership averages — not a target for your counter. Your manager may supervise three techs and one advisor, handle customer callbacks personally and still turn a wrench on Mondays. What transfers from the dealership picture is the span of the job: production, people, paperwork and the department's numbers all report to one seat.

Draw the seams in your own org chart before you hire. Decide where the foreman seat ends and this one starts — you might put the foreman on wrench-time supervision and the manager on the schedule, the counter and the numbers, or merge the two chairs. Decide the same for the advisor desk: selling and closing work is advisor work, owning the department is manager work.

For the full role profile — the day-to-day work, the settings and the career path — see what a service manager does, then write your shop's version of it.

Start inside the trade. Look first at your own senior tech, your foreman, your best advisor, and the managers running service departments at dealers, chains and competing independents around you. An internal move arrives already knowing your customers and your software; an outside hire arrives knowing a different way to run a board — and section four is how you tell them apart.

The pool sits where the technician workforce sits. BLS's Occupational Outlook Handbook counted about 825,800 automotive service technician and mechanic jobs in 2025, with 32% at automobile dealers, 25% at automotive mechanical and electrical repair shops, and 15% self-employed. Dealers, independents and chains are all part of that pond.

The pond circulates, too. BLS projects an average of 66,200 openings a year for automotive service technicians and mechanics over 2025–35, mostly from replacing workers who change occupations or retire. Movement cuts both ways. The openings that let you hire a manager out of a dealer lane or a chain are the same kind of openings that can take people off your own bench. That is why the last section treats retention as part of hiring.

Work the channels in this order:

• Your own shop first. An internal move brings your process knowledge and working relationships the candidate already has; the management screen in the screening section below matters more than the resume, because the move from wrench to manager is a bigger change than a move between shops.
• Dealer fixed-ops. Assistant service managers, dispatchers and dealer foremen run department work at the dealership scale from section one; recruit them on what a smaller shop can offer that a dealer lane cannot — schedule, breadth, a seat that reports to the owner.
• Chain and quick-lube stores. Store and general managers there run crews and numbers in a different trade; whether the management repetitions transfer to a repair department is exactly what the screening section below tests.
• Managers at competing independents. An experienced hire arrives with the job already learned — recruit on your schedule, your plan and what makes your shop genuinely different.

Wherever you source them, the posting has to sit where shop people already look. The cross-role guide to where to post shop jobs walks the channels in detail.

The post is your filter and your legal surface at once. Describe the scope you wrote down in section one: the span of control, the schedule including Saturdays and opening or closing rotation, the pay plan type, the benefits, and the shop management software you run — named as your own stack, not ranked.

State your credential stance plainly, too. ASE certification is voluntary, so if you want a credentialed manager, say the requirement is your shop's or an OEM program's, never the law's.

Then there is the pay line. These states require it in the posting itself:

• California: employers with 15 or more employees must include the pay scale in any job posting and give it to any job board or recruiter they post through. A pay scale is a good-faith estimate of the salary or hourly range the employer reasonably expects to pay upon hire.
• New York: employers with four or more employees must disclose the compensation or a range of compensation, plus the job description if one exists, for jobs performed at least in part in New York.
• Washington: employers with 15 or more employees must disclose the wage scale or salary range — or the fixed wage, if only one amount is offered — and a general description of all benefits and other compensation.
• Illinois: employers with 15 or more employees must include the pay scale and benefits in specific job postings for positions performed at least partly in Illinois — a rule in effect for postings after January 1, 2025.
• Massachusetts: starting October 29, 2025, employers with 25 or more employees in the state must disclose the pay range in job postings.
• Minnesota: employers with 30 or more employees at one or more Minnesota sites must post the starting salary range or a fixed pay rate plus a general description of benefits and other compensation, and the range may not be open-ended.
• Colorado: compensation must be disclosed in all job postings and notices, internal and public, together with benefits information and how and when to apply.
• Maryland: for positions performed at least in part in Maryland, the wage range and a general description of benefits and other compensation go in each posting, set in good faith.

Size changes the answer. Census County Business Patterns counted 84,859 general automotive repair establishments in 2023, with 55,637 of them employing fewer than 5 people and another 20,883 employing 5 to 9 — roughly nine in ten general repair shops run with fewer than 10 employees. That keeps most independent shops under the 15-, 25- and 30-employee lines; New York's line sits at four employees, so even a small crew hiring a manager can be covered.

New York's law carves out wording for one pay type: a job paid solely on commission complies by including a general statement that compensation will be based on commission. Read that narrowly. A manager plan with any salary or base behind the bonus is not paid solely on commission, so post the good-faith minimum and maximum range the law defines.

Watch the adjectives, too. The EEOC treats a help-wanted ad that shows a preference based on a protected trait as unlawful, and its own example is an ad seeking “recent college graduates,” which may discourage people over 40 from applying and may violate the law. Keep age-coded phrases — young, energetic, recent grad — out of a manager ad.

Rules change. These thresholds, dates and carve-outs are the versions the agency pages showed when we checked; confirm the current requirement with your state labor agency before you publish the post.

A manager interview audits judgment, not charm. Build the screen around the decisions the seat makes every week:

• Schedule and assignment drill. Hand over a made-up week — three techs (one strong diagnostic, one green, one mid), a queue of open repair orders, one advisor out — and have them build the board aloud: who gets what, in what order, and why. Assigning work by priority and by each person's skill is the exact task O*NET lists for this occupation.
• Declined-work walkthrough. Give them an anonymized repair order with declined recommendations and ask two things: what they would have done differently at authorization, and how they would coach the advisor who wrote it.
• Comeback case. Describe a disputed comeback — the tech blames the parts, the customer blames the shop — and ask how they inspect the completed work and what they say at the counter. You are listening for a process, not a verdict.
• Numbers conversation. Sit them with one month of your own anonymized figures — repair orders, hours sold, comebacks — and ask what they would look at first. You are listening for how they think about the department, not for a target they can quote.
• Software walk-through. If the resume claims shop management system experience, have them show it — open a repair order, reassign a job, pull a report.

Keep the exercises lawful as well as realistic: the EEOC requires that a required test be necessary and related to the job, and that it not exclude people based on a protected trait. A screen that tends to knock out applicants 40 or older needs a reasonable factor other than age.

Know which federal rules cover you: the equal-pay law reaches employers with at least one employee, Title VII, the ADA and GINA start at 15 employees, and the age-discrimination law starts at 20. State and local laws can reach smaller shops.

Before a conditional offer, skip disability and medical questions; you may ask whether the candidate can perform the job's duties and how they would perform them. Marital status, plans to marry and the number or ages of children generally should not come up before hire, and most employers should not ask about citizenship before an offer — the Form I-9 process may not run before the offer is accepted.

After a conditional offer, a medical exam or disability-related questions are allowed only if every new hire in the same job completes the same step, with the answers kept confidential in separate files. Criminal records can be considered at the final decision stage, but applicants may not be treated differently based on race or national origin when you weigh them.

Pay history is its own trap. California, Illinois and Colorado bar employers from seeking an applicant's salary history, while California and Illinois allow asking about salary expectations, and California notes an applicant may volunteer history unprompted. Ask what they expect to earn, and present your plan.

Start with what you cannot quote. No published wage table describes a service-department manager's seat. The closest federal code is O*NET's 49-1011 — supervisors of mechanics, installers and repairers across every repair trade — and it is a proxy, not a match. Figures averaged from it describe supervisors of many trades, not your manager hire. Set the offer from your own market: what dealers, chains and competing independents publish in their own postings, and the plan you design.

Choose the structure deliberately. A straight salary is the simplest to budget. Salary plus a bonus tied to goals you set adds upside without handing over the keys. Base plus a share of department performance moves more of both the upside and the risk onto the manager, and full commission shifts the most risk to them.

Whatever you pick, write the whole plan down before the offer — the base, what the bonus is measured on, when it pays out, and what happens in a slow month.

Then treat every payout as wages. Bonuses, commissions and awards are supplemental wages subject to employment taxes and reported on Form W-2, with an optional flat 22% federal income tax withholding rate. Price the employer taxes behind a promised bonus before you promise it.

Two wage-hour rails shape a manager plan. First, a fixed salary does not by itself satisfy the FLSA for a workweek over 40 hours — the Department of Labor's own example divides a $405 salary across 45 hours, computes a $9.00 regular rate and adds half-time premium for the five overtime hours. Second, the dealership overtime exemption, 29 U.S.C. 213(b)(10)(A), names salesmen, partsmen and mechanics; it does not name managers, and it removes overtime only — never minimum wage. How these rules land on your manager's actual duties in your establishment is a question to take to the DOL or your counsel.

Put the benefits in writing too, because state law makes them disclosure content in covered postings: Washington and Maryland require a general description of benefits and other compensation, Illinois requires the benefits alongside the pay scale, and Colorado requires benefits information with every posting. Health coverage, paid time off, a retirement match, a training budget, uniforms — the mix is yours to set.

The employer-side guides on hiring for your shop cover pay plans, screening and onboarding for the rest of the bays and the front counter.

Onboarding starts before day one: have the system logins, the org chart and a written scope — the one from section one — ready. Then pace the ramp:

• Week one. Ride the whole operation: shadow the counter, the board and dispatch, and sit through one comeback from complaint to invoice.
• Weeks two to four. Take the board with backup; review their schedule decisions and repair-order authorizations daily until the judgment is yours to trust.
• By 90 days. Own the department rhythm — the schedule, the advisor coaching, a weekly numbers review — and run one staff meeting on their own.

Pay for the training time. Under the FLSA's training-time rule (29 CFR 785.27), time in lectures, meetings and training counts as paid working time unless all four of these hold: it is outside regular hours, truly voluntary, not directly related to the employee's job, and no productive work is performed. Your new manager's required courses and safety meetings are not "truly voluntary," so they are generally hours you pay for.

Set the manager's targets from your own records, not a borrowed average: repair orders per day, hours sold, comebacks, declined-work follow-ups — your shop management system already holds the inputs. A target built from your own last twelve months is one the manager can act on; a number quoted at a seminar is decoration.

Plan to keep them, too. BLS's Employee Tenure survey put the median time with a current employer at 4.4 years for installation, maintenance and repair occupations in January 2026 — the occupation group this seat supervises — versus 4.1 years for all workers. Retention is a habit, not a plaque: a schedule the manager can actually hold, a written pay plan you review together, one-on-one time with the techs and advisors they run, and a ladder you can name out loud.

Ask what would make them leave before a competitor does. A quarterly stay conversation costs an hour and surfaces the fixable stuff early — schedule drift, a stalled review, a bonus formula nobody can explain.

Employer information, not legal, tax or insurance advice. Pay-posting, interview, wage-hour and overtime rules come from federal and state agencies; confirm your specifics with your state labor agency, the DOL, the EEOC, a CPA or counsel.
