Staffing agencies in Michigan: 3,112 locations, 4th among states, and when an agency fee pays for itself

This report covers Michigan as a whole: employers and job seekers outside the big metros, analysts sizing the state, and B2B sellers planning a Michigan territory. Metro detail is in staffing agencies in Detroit and staffing agencies in Grand Rapids.

Michigan staffing agencies by the numbers

US Census Bureau, County Business Patterns 2023, State of Michigan, NAICS 56131 (Employment Placement Agencies and Executive Search Services) and 56132 (Temporary Help Services):

Every size class is published for Michigan. In broader bands, 2,322 establishments have 1 to 19 employees, 508 have 20 to 99 and 282 have 100 or more.

Why the counts look the way they do

Two things inflate Michigan's figures, and both matter if you're using them to size a market.

Temps are counted as agency employees. The Census definition of temporary help services says the workers supplied "are employees of the temporary help services establishment." Kelly Services shows the scale of the effect: its 2025 annual report says it placed about 375,000 workers with customers around the globe, together with supplier partners, while employing about 3,600 full-time staff in the United States and 1,300 abroad.

Half the establishments have no county. The Census Bureau puts employers "without a fixed location within a state (or of unknown county location)" in a statewide category, and notes that employment services firms may pay their workers out of a single payroll office. Michigan's county file shows how much this matters here:

"Not reported (high-noise figure)": the Census Bureau published Ingham's total but flagged it, because the noise it adds for confidentiality changed it by 5% or more. The statewide group holds 49% of Michigan's establishments and 59% of its employees. It includes 1,509 temp help records, 1,078 of them with fewer than five employees, which accounts for most of the state's unusually long tail of very small establishments, and 13 of its 14 establishments with 1,000 or more employees.

Other limits. These are establishments with paid employees, not companies, so one firm can appear many times, and self-employed recruiters aren't counted. Employment is one week in March 2023. Professional employer organizations are counted under NAICS 56133, not here.

Michigan's public staffing company

Revenue is as reported in Kelly's 10-K for 2025, which also says its headquarters is a leased facility in Troy.

The Michigan rule for job seekers and agencies

Michigan's Occupational Code licenses personnel agencies (MCL 339.1001 and 339.1003). A type A personnel agency puts a job seeker in touch with employers and takes a fee from the job seeker; a type B agency charges for career consulting. Neither may operate without a state license. The code exempts a business that employs people to do temporary or part-time work for a third party, as long as it pays their wages, Social Security, unemployment insurance and workers' disability compensation and stays responsible for their acts.

Michigan's minimum wage is $13.73 an hour, rising to $15.00 on 1 January 2027 (US Department of Labor state table), so contracts that run past the new year need a second pay rate.

Worked example: when an agency fee pays for itself

Illustrative example. The company, salary, fee and vacancy costs are invented to show the arithmetic.

Huron Ridge Controls (huronridge.example), an automotive supplier, needs a controls engineer at $105,000. Its own recruiting would take 12 weeks and $3,000 in job ads. A contingency search firm expects to fill it in 6 weeks for a 20% fee: $21,000.

The agency saves 6 weeks for $18,000 more in direct cost, so it pays for itself when each week the job sits empty costs more than $3,000 (overtime for colleagues, delayed launches, a contract engineer). Estimate that weekly cost before you decide; on roles tied to a program launch it's usually the biggest number in the calculation.

Selling to Michigan staffing agencies

For a state territory, start from the counties with real branches, Oakland, Wayne, Kent and Macomb, then treat the statewide records as a signal of companies running Michigan payroll centrally, where payroll, timekeeping and compliance decisions sit. Engineering and IT contract firms serving the auto industry buy differently from light industrial staffers: candidate data, credential checks and vendor management integrations rather than safety and transport. Read job posts to sort them. Separating real branches from payroll records takes research; Bebop finds agencies that match a description and explains why each fits.

I saw [agency] is recruiting [number] [role, e.g. controls and validation engineers] for programs in [area]. When a launch date is fixed, onboarding paperwork is often what delays a contractor's first day on site.

We [what you do, e.g. collect and verify onboarding documents and client-specific requirements before day one].

Would it help to try it on your next start?
