The numbers
US Census Bureau, County Business Patterns 2023, for the Cincinnati, OH-KY-IN Metro Area (CBSA 17140), NAICS 56131 (Employment Placement Agencies and Executive Search Services) and 56132 (Temporary Help Services):
| Measure (2023) | Cincinnati metro |
|---|---|
| Establishments | 375 |
| Employees (week of March 12) | 25,800 |
| Annual payroll | $971,625,000 |
| Average employees per establishment | 68.8 |
| Average annual pay | $37,660 |
| Share of US establishments | 0.72% of 51,830 |
| Industry (NAICS, 2023) | Establishments | Employees | Annual payroll | Average annual pay |
|---|---|---|---|---|
| Temporary help services (561320) | 293 | 24,006 | $892,528,000 | about $37,200 |
| Employment placement agencies (561311) | 50 | 1,641 | $66,460,000 | about $40,500 |
| Executive search services (561312) | 32 | 153 | $12,637,000 | about $82,600 |
Temp help is 78% of the locations and 93% of the jobs. A temp agency is the legal employer of the people it places, and the Census Bureau counts them at the agency's branch, not at the plant or warehouse where they work. That's how 293 branches come to average 82 employees each.
Big branches, and where they are
| Employees per establishment | Establishments |
|---|---|
| 1 to 4 | 138 |
| 5 to 9 | 32 |
| 10 to 19 | 30 |
| 20 to 49 | 50 |
| 50 to 99 | 46 |
| 100 to 249 | Not published |
| 250 to 499 | Not published |
| 500 to 999 | Not published |
| 1,000 or more | Not published |
In broader bands, 200 establishments have 1 to 19 employees, 96 have 20 to 99 and 79 have 100 or more; the 79 is the total less the smaller bands, because the Census Bureau doesn't publish the top classes for the combined codes. The temp help row shows the detail: 46 branches with 100 to 249 employees, 23 with 250 to 499 and 6 with 500 to 999. Its classes account for all 293 branches, so none has 1,000 or more.
| County | Establishments | Employees | Per location |
|---|---|---|---|
| Hamilton County, Ohio | 201 | 13,452 | 66.9 |
| Butler County, Ohio | 52 | 4,320 | 83.1 |
| Boone County, Kentucky | 43 | 4,740 | 110.2 |
| Warren County, Ohio | 37 | 1,177 | 31.8 |
| Kenton County, Kentucky | 18 | 1,583 | 87.9 |
| Clermont County, Ohio | 12 | Not reported (high-noise figure) | |
| Dearborn County, Indiana | 4 | 44 | 11.0 |
| Campbell County, Kentucky | 3 | Not reported (high-noise figure) |
The Census Bureau published the Clermont and Campbell employee figures but flagged them as high-noise: confidentiality noise moved them by 5% or more. These eight counties hold 370 of the 375 locations. The Northern Kentucky counties have 64 agencies between them, but Boone and Kenton alone carry 6,323 employees, a quarter of the metro's staffing headcount.
The counts are establishments with paid employees, not companies, so a national firm with branches in Blue Ash, West Chester and Florence counts three times, and self-employed recruiters aren't included. Professional employer organizations are a separate industry here (21 locations, 637 employees). No SEC-registered listed staffing company has its headquarters in the metro.
The kinds of agency you'll meet
| Type | Use it for | What to ask |
|---|---|---|
| Light industrial and warehouse temp | Distribution and manufacturing shifts | Shift differentials, overtime billing, attendance policy |
| Temp-to-hire | Production or office roles you want to try out | Hours before free conversion |
| Office, finance and IT contract | Project and backfill roles | Minimum term, rate for overtime |
| Healthcare staffing | Nurses, aides and technicians | Credential checks, replacement time |
| Direct hire placement | Permanent hires | Fee as share of salary, replacement guarantee |
| Executive search | Senior roles | Retainer stages, off-limits terms |
| PEO | Payroll and benefits for your existing staff | Which state registrations it holds |
The state rules, by side of the river
The metro spans three states, and the rules follow where the agency operates and where the work is done.
Kentucky. Kentucky's employment agency chapter, KRS Chapter 340, was repealed in 2000, so there is no state licence for a general staffing agency to show you. Professional employer organizations are different: KRS 336.236 required anyone providing professional employer services in Kentucky to be registered with the Department of Workers' Claims by 15 July 2024, and after that date an unregistered business may not offer PEO services or use names such as "PEO" or "employee leasing company." Registration requires ownership details and an audited financial statement filed each year.
Ohio. Ask an Ohio agency for its workers' compensation certificate from the Ohio Bureau of Workers' Compensation and confirm its entity status with the Ohio Secretary of State. If you're using a PEO for Ohio staff, ask which Ohio filings it maintains.
For a client with sites in both states, get certificates that cover each state where the agency's temps will work; a policy written for one state may not cover the other.
How to vet a Cincinnati agency
- Decide the type from the table above, and whether you need one agency for sites in both states.
- Check certificates and status in each state where the agency will employ people for you.
- Get the rate card: pay rate, markup, overtime bill rate, shift differential treatment and conversion terms.
- Ask for attendance numbers. At big branches the cost of a no-show is the line that stops; ask what share of ordered shifts the branch filled last quarter.
- Read ratings on ClearlyRated and call two clients running similar shifts.
Worked example: is the night differential marked up?
Illustrative example. The company, rates and markup are invented to show the arithmetic.
Licking River Cross-Dock (lickingriver.example) in Boone County orders 25 night-shift temps for 16 weeks at 40 hours a week: 16,000 hours. Base pay is $19.00 plus a $2.00 night differential, and the agency's markup is 40%. Agencies bill the differential one of two ways:
| Method | Bill rate | 16,000 hours |
|---|---|---|
| Markup on base pay and differential: $21.00 × 1.40 | $29.40 | $470,400.00 |
| Markup on base pay, differential at cost: $19.00 × 1.40 + $2.00 | $28.60 | $457,600.00 |
| Difference | $0.80 | $12,800.00 |
The differential is real wages, and payroll taxes and workers' compensation apply to it, so some markup on it is fair; a full 40% may not be. Ask before the order, not at the first invoice.
If you're looking for work
Agencies are paid by the employers they staff, so you shouldn't pay to register. Night and weekend shifts usually pay a differential; ask what it is before you accept. If you're offered a job through a PEO, the PEO handles payroll for an employer that has already hired you.
Selling to Cincinnati staffing agencies
The branches are large, which suits vendors selling per-worker tools: timekeeping and attendance, shift confirmation, screening, safety training, uniforms and protective equipment, and transport.
| Establishment size | Count | Who usually decides |
|---|---|---|
| 1 to 19 employees | 200 | The owner or a lead recruiter |
| 20 to 99 employees | 96 | Branch manager, with the owner signing |
| 100 or more employees | 79 | Area or regional operations; national firms often buy centrally |
Start with the 79 big locations, then split them by county and state: Boone and Butler branches average more than 80 employees, Hamilton's 67. Read each branch's job postings for shift patterns and volumes. At volume the research is the slow part; Bebop finds agencies matching a description and explains why each fits.

Subject: Night-shift no-shows at [client site type] Hi [first name], I saw [agency] is filling [number] night roles around [town] this month. On a 25-person night order, three no-shows is a late call to the client and a scramble before 10 pm. Our [product] confirms each shift by text two hours out and fills gaps from your standby list. Would it be worth testing on one order? [Your name]

Questions people ask
How many staffing agencies are there in Cincinnati?
Census County Business Patterns counted 375 staffing agency establishments in the Cincinnati metro in 2023, employing 25,800 people: 293 temp help branches, 50 employment placement agencies and 32 executive search offices. Hamilton County had 201, Butler County 52 and Boone County, Kentucky, 43. These are locations with paid employees, so a firm with several branches counts several times.
Do staffing agencies need a license in Kentucky?
Kentucky has no licence for general staffing or employment agencies: its employment agency chapter, KRS 340, was repealed in 2000. Professional employer organizations must be registered with the Department of Workers' Claims under KRS 336.236, which set a 15 July 2024 deadline. For a temp agency, check its business registration and ask for its workers' compensation certificate.
Why are Cincinnati staffing agencies so large?
Because temps are counted where they're employed, at the agency's branch, not at the client's site. The metro's 293 temp help branches carry 24,006 employees, about 82 each, and 29 of them have 250 or more. Boone County, Kentucky, averages about 110 employees per staffing location, the highest in the metro, against about 67 in Hamilton County.
How do temp agencies bill shift differentials?
Either with the markup applied to the whole pay rate, differential included, or with the markup on base pay and the differential added at cost. On a 40% markup and a $2.00 night differential the gap is $0.80 an hour, which comes to $12,800 over 16,000 hours. Neither is standard, so ask for the method in writing before you place the order.
