A service advisor is the front-counter professional who connects a shop's customers, its technicians and its business.
The advisor documents the customer's concern on a repair order, obtains authorization for the work, follows the job through the shop, and explains the results and the invoice at pickup.
Dealerships, independent shops and quick lubes have their own versions of the counter job, under titles such as service writer, service consultant and customer service advisor.
What is a service advisor (service writer or service consultant)?
The service advisor sits at the service counter and owns the conversation that turns a vehicle problem into an authorized repair.
A customer describes a symptom; the advisor translates it into a documented concern, a repair order and an estimate the customer can approve, then follows the job through the shop to pickup.
The job is distinct from the technician's, and the credential built for the counter draws the same line: ASE counts service-writing experience toward it, not hands-on repair.
The record in the Supreme Court's Encino Motorcars case describes advisors as the workers who meet and greet vehicle owners, solicit and suggest repair and supplemental services, and give cost estimates.
Service writer is a working title for the same counter job, and federal statistics treat the two together; ASE likewise counts service writer and consultant experience together toward its C1 credential.
In the O*NET occupational database, the titles 'Service Writer' and 'Automotive Service Writer' are linked to the same occupation as 'Service Advisor', and no federal data series reports service writers separately from service advisors.
There is no dedicated SOC code for the role.
O*NET's current release (31.0) links 'Service Advisor' and 'Automotive Service Advisor' chiefly to 43-4051 Customer Service Representatives, and none of those links come from the official SOC index itself.
The classification has moved before.
The prior O*NET release (30.2) linked advisor titles to 49-3023 Automotive Service Technicians and Mechanics; that link is gone in the current 31.0 file, so O*NET's download no longer files advisors with technicians.
Search O*NET's own keyword tool for 'service advisor' and the top match is customer service representatives, followed by automotive service technicians and mechanics, then first-line supervisors of mechanics — a relevance ranking, not an official crosswalk.
For career research the effect is simple: no federal data series has a service-advisor line of its own.
Any federal pay or outlook figure for this role is borrowed from another occupation, and the pay section below shows which one and how well it fits.

What does a service advisor do all day?
The advisor's day runs on the repair order, from the first greeting to the final invoice.
ASE's task list for its C1 Automobile Service Consultant credential is a good map of the counter job.
It includes confirming the repair order and obtaining the customer's authorization, documenting the customer's concern, performing and documenting a vehicle condition check at drop-off, and documenting which recommended services the customer accepted or declined.
The job has a sales and communication core as well.
ASE's C1 task list covers explaining inspection results and estimates, prioritizing and presenting service recommendations, communicating the value of additional services, and overcoming objections.
Warranty and payment knowledge is part of the work too.
ASE expects service consultants to know warranty policies, service contracts, technical service bulletins and campaigns or recalls, and to identify the customer type and source of payment: first-time, warranty, repeat repair or fleet.
ASE's own test blueprint shows where the test's weight sits: 23 of the C1 test's 50 scored questions (46%) cover communications, 18 (36%) cover product knowledge, and 9 (18%) cover shop operations.
One dated dealership guideline gives a sense of the volume.
NADA's 2010 service guide says each service advisor should write 18 to 22 repair orders a day, totaling 40 to 50 flat-rate hours, with single-item repair orders only 10 to 15% of them — a guideline, not a measured average.
Ask at the interview
Where do service advisors work?
Dealerships put the advisor at the center of the service department, and their service operations run at scale.
NADA Data counted 16,990 franchised new light-vehicle dealerships in the U.S. in 2025, writing more than 276 million repair orders in a year, with service and parts sales topping $164 billion.
The average franchised store in NADA's 2025 data wrote 16,252 repair orders and booked $9,687,942 in service and parts sales; service and parts accounted for 13.3% of total dealership sales dollars.
Outside dealerships, Census County Business Patterns counted 169,572 automotive repair and maintenance establishments with paid employees in 2023, independent shops and chain stores alike, employing 992,292 people, including 84,859 shops classified as general automotive repair.
Those shops run small: 102,158 of the 169,572 establishments had fewer than five employees in the same count.
On a team that size, the counter, the phones and the front office can be one person's job.
Quick lubes staff the same counter under their own titles.
Jiffy Lube, for example, calls its front-counter role Customer Service Advisor (CSA) and describes it as educating customers on recommended services.
Its Jiffy Lube University training, the company says, is ASE Accredited Training Provider curriculum recognized by the American Council on Education.
What do you need to become a service advisor?
The credential built for the role is ASE's C1 Automobile Service Consultant certification.
The C1 test has 50 scored questions covering communications, customer and internal relations, vehicle systems knowledge, sales skills and shop operations.
Certification requires passing the test plus two years of work experience in service writing.
ASE counts experience as an automotive service writer or consultant, or as a service manager, toward that requirement — hands-on repair experience does not count, and neither do school or training substitutions.
You can sit the C1 test before you have the experience.
ASE issues a score report, but the certificate waits until the two-year experience requirement is met.
C1 consultants recertify on ASE's five-year cycle.
The C1R recertification test runs 25 questions in 30 minutes, against 50 scored questions in 75 minutes for the initial test.
ASE's initial certification tests cost $62 per test plus a $34 registration fee per order — the general-test bracket that covers C1, which ASE's fee list does not name separately — the fees ase.com listed when this page was researched in 2026.
ASE frames C1 as voluntary: its stated purpose is improving vehicle service through the voluntary testing and certification of service consultants.
What any given employer asks for is that employer's own rule.

How much do service advisors make and how are they paid?
Start with what the federal numbers do and do not cover.
BLS's OEWS pay table has no occupation titled service advisor, service writer or service consultant — the May 2025 national file names no such occupation — so there is no official advisor median wage to quote.
The nearest proxy O*NET links the title to, 43-4051 Customer Service Representatives, had a BLS median of $21.53 an hour in May 2025 — and BLS projects that occupation to decline 5% from 2025 to 2035.
Both numbers deserve caution for this role.
O*NET's definition of the customer-service occupation excludes individuals whose duties are primarily sales, repair or technical support, which makes it an imperfect stand-in for the advisor's mix of sales, repair knowledge and customer work.
The projected decline, meanwhile, is driven by automation of scripted call-center and retail inquiries — not by anything happening at the service counter.
How any given shop pays its advisors is that shop's own plan; our research found no primary source for a typical advisor pay structure or commission split.
In the Encino Motorcars case, the dealership's advisors were paid on a pure commission basis — one employer's pay plan from one lawsuit, not evidence of a national structure.
Ask for any plan you are offered in writing: the base, the commission basis, and how customer-pay, warranty and internal hours each count.
One federal rule shapes advisor pay directly.
In the Encino Motorcars case, decided April 2, 2018, the U.S. Supreme Court held 5-4 that dealership service advisors are exempt from FLSA overtime under 29 U.S.C. §213(b)(10)(A).
The exemption is narrow.
It covers a salesman, partsman or mechanic primarily engaged in selling or servicing automobiles, and only at a nonmanufacturing establishment primarily engaged in selling such vehicles to ultimate purchasers.
That leaves advisors at independent shops and chains that do not sell vehicles outside the exemption.
Wage-and-hour questions belong with the U.S. Department of Labor's Wage and Hour Division or your state labor department — they can tell you how the rules apply to a specific offer, which this page cannot.
What is the career path from advisor to service manager?
The counter is not the top of the shop ladder.
Above it in the service department sits the service manager — and that step up is a real occupational line: O*NET links 'Service Manager' and 'Automotive Service Manager' to 49-1011 First-Line Supervisors of Mechanics, Installers, and Repairers.
ASE treats the two jobs as one experience family: time as a service manager counts toward the advisor's C1 credential, just as service-writing time does.
The same federal group covers the trade's other supervisor titles too: O*NET links 'Shop Foreman', 'Shop Manager', 'Garage Manager' and 'Body Shop Supervisor' to 49-1011.
What changes at that step is the unit you own.
O*NET's task data for 49-1011 supervisors includes deciding work schedules and assignments based on priority and staff skill, inspecting completed work, monitoring staff performance and doing skilled repair work themselves.
The supervisor definition even keeps a customer-facing duty: O*NET says these supervisors directly supervise and coordinate mechanics and may also advise customers on recommended services, and it excludes team or work leaders from the group.
Federal data does publish pay for this group.
Within automotive industries in May 2025, the 49-1011 supervisor group — the closest federal group to a service manager — had a median of $84,420 a year at automobile dealers and $70,930 a year at automotive repair and maintenance shops.
Management education exists for this ladder too.
The Automotive Management Institute (AMI), a 501(c)(3) nonprofit, offers management designations and certificates such as Accredited Automotive Manager (AAM) for the mechanical service and collision repair segments.
