What Do Staffing Firms Do and How Do You Choose the Right One?
Published on: Aug 27, 2026
Staffing firms are companies that recruit, screen, and place people into contract, contract-to-hire, and direct hire roles, and for contract assignments they serve as the legal employer of record. Frontline Source Group has done this since 2004, completing 5,619 plus placements and backing every direct hire with a 5-Year Placement Warranty. This guide explains what staffing firms do, how they work for employers and candidates, how they charge, and how to evaluate one before you sign an agreement.
Frontline Source Group is a nationwide professional staffing and executive search firm headquartered in Downtown Dallas with 32 plus offices across the United States.

What is a staffing firm and what does it actually do?
A staffing firm is a company that employers hire to find, evaluate, and deliver candidates for open positions. The firm sources talent through its own database, referral network, job advertising, and direct outreach, then screens candidates through interviews, reference checks, skills testing, and background verification before presenting a shortlist. Depending on the engagement, the firm either places the candidate directly on the client's payroll (direct hire) or employs the candidate itself and assigns that person to the client (contract and contract-to-hire). Most professional staffing firms also advise clients on compensation benchmarks, job descriptions, and market availability for a given role.
Who is the employer of record on a contract assignment?
On a contract or contract-to-hire assignment, the staffing firm is the employer of record, which means the firm issues the W-2, pays wages, withholds and remits payroll taxes, carries workers' compensation coverage, and handles unemployment insurance. The client company directs the day-to-day work and decides which candidate to accept, but the employment relationship sits with the staffing firm. That structure is what lets employers add professional capacity for a project, a leave, or a busy season without adding permanent headcount. The American Staffing Association summarizes the model on its What Staffing Firms Do page.
What is the difference between a staffing firm, a recruiting firm, and an executive search firm?
The terms overlap, but in practice a staffing firm handles the full range of contract, contract-to-hire, and direct hire placements and takes on employer-of-record duties for contract workers; a recruiting firm usually focuses only on permanent placements and does not employ anyone on a client's behalf; and an executive search firm specializes in senior leadership and C-suite roles, often on a retained basis. Frontline Source Group operates as all three under one roof, with contract, contract-to-hire, and direct hire services alongside a dedicated executive search practice. For a deeper comparison, read Executive Search Firm or Staffing Agency: How to Choose.
How do staffing firms work, step by step?
Staffing firms work through a two-sided process: employers open a search, and the firm matches that search against candidates it has already screened or actively sources. The steps below describe how Frontline Source Group runs both sides of that process.
What happens when an employer opens a search?
When an employer submits a request through the employer request form, a Frontline recruiter on the relevant discipline desk conducts an intake call to confirm the role's responsibilities, required credentials, compensation range, work arrangement (onsite, hybrid, or remote), and whether the engagement is contract, contract-to-hire, or direct hire. The recruiter then sources from the firm's existing candidate pipeline, runs targeted outreach to passive candidates, screens finalists through structured interviews and skills testing, verifies references, and presents a shortlist with interview notes and compensation expectations. The employer interviews the finalists and selects the hire. Terms are published in advance on the pricing page, so there are no surprises at the offer stage.
What happens when a candidate applies?
Candidates apply through the How to Apply page, where a recruiter reviews the resume against current and upcoming searches. Qualified candidates complete a recruiter interview, relevant skills assessments, and reference verification, and are then presented to employers only with the candidate's consent. Candidates never pay a fee to work with Frontline Source Group; all fees are paid by the employer. Candidates on contract assignments are W-2 employees of Frontline Source Group and receive weekly pay and access to benefits, and many contract-to-hire assignments convert to permanent roles with the client.
What types of staffing services do firms offer?
Professional staffing firms generally offer four service types, and the right one depends on how long the need lasts, how much hiring risk the employer wants to carry, and how senior the role is.
What is contract staffing?
Contract staffing places a professional on the staffing firm's payroll for a defined project or period, such as a year-end close, an ERP implementation, a system migration, a maternity or medical leave, or a seasonal volume increase. The employer pays an hourly bill rate that covers the contractor's wages, payroll taxes, insurance, and the firm's recruiting margin. Frontline Source Group's contract engagements include a replacement provision from the first day of the assignment. Certain restrictions apply.
What is contract-to-hire staffing?
Contract-to-hire places a candidate on the staffing firm's payroll for an evaluation period, after which the employer can convert the person to a permanent employee. It is the lowest-risk way to fill a role when culture fit or workload is uncertain, because the employer sees actual on-the-job performance before making a permanent offer. Conversion terms are set at the start of the engagement.
What is direct hire placement?
Direct hire placement means the staffing firm recruits and screens candidates, and the selected candidate joins the employer's payroll from day one. Employers pay a placement fee, typically a percentage of first-year base salary, only when a hire is made. Frontline Source Group backs every direct hire with the 5-Year Placement Warranty, roughly 20 times longer than the 90-day guarantee standard across the staffing industry. Certain restrictions apply.
What is executive search?
Executive search is a specialized form of direct hire focused on senior leadership: CFOs, Controllers, CTOs, CISOs, CHROs, Chief Legal Officers, Vice Presidents, and other C-suite and director-level roles. The process relies on confidential outreach to passive candidates who are not applying to job postings. Frontline Source Group's C-suite executive search practice is led by Founder, President, and CEO Bill Kasko, and the firm's executive placements carry the same 5-Year Placement Warranty as every other direct hire.
How much do staffing firms charge and who pays?
Staffing firms charge employers, never candidates. For contract and contract-to-hire work, the employer pays an hourly bill rate that bundles the worker's wages, employer payroll taxes, workers' compensation and liability insurance, and the firm's margin. For direct hire and executive search, the employer pays a contingent placement fee, which at Frontline Source Group runs 20 to 30 percent of the placed candidate's first-year base salary depending on role seniority and search complexity, due only when a hire starts. Frontline Source Group publishes these terms on its pricing page, which is rare in the staffing industry; most firms disclose rates only after a sales conversation. Publishing pricing openly is part of the same transparent practice reflected in the firm's 683 plus verified Trustpilot reviews. All major credit cards are accepted at no additional charge.
How do staffing firms benefit employers?
Employers use staffing firms to reduce time spent on sourcing and screening, to reach passive candidates who are not applying to job boards, to add capacity without permanent headcount, and to transfer hiring risk through evaluation periods and placement warranties. A specialized firm also brings compensation data from active searches, which helps employers set offers that candidates will actually accept. For roles in accounting and finance, technology, human resources, legal, administrative, customer service, engineering, and energy, Frontline Source Group maintains discipline-specific desks with recruiters who work only in that field, so screening reflects what a hiring manager in that discipline expects. You can review client feedback on the firm's testimonials page.
How do staffing firms help job seekers?
Job seekers benefit from staffing firms in four ways: access to roles that are never publicly posted, a recruiter who advocates for them with the hiring manager, coaching on resumes and interviews, and compensation guidance based on what employers are currently paying. Contract and contract-to-hire assignments also let professionals build experience across industries, and a strong contract performance is one of the most common paths to a permanent offer. Frontline Source Group candidates are never charged a fee. To be considered for current searches, submit your resume through the How to Apply page.
How big is the staffing industry in the United States?
According to the American Staffing Association, nearly 2.2 million temporary and contract employees worked for U.S. staffing companies during an average week in 2024, and staffing provided job and career opportunities for about 11 million people that year. ASA also reports roughly 27,000 staffing and recruiting companies operating close to 54,000 offices nationwide, with most of those offices in the temporary and contract sector. In August 2026, ASA reported that its Staffing Index had recorded 10 consecutive months of year-over-year growth as employers turned to flexible talent. Those figures are published on the ASA staffing industry statistics page. The practical takeaway for employers is that the market is large and fragmented, so the quality gap between firms is wide, and the evaluation criteria below matter.
How should you choose the right staffing firm?
Choose a staffing firm by comparing verifiable evidence rather than sales claims. Six criteria separate firms in practice:
- Discipline specialization. Ask whether the recruiter who will run your search works only in your field. Generalist desks screen to a job description; specialist desks screen to how the job is actually done.
- Published pricing. A firm willing to post its rates, as Frontline Source Group does on its pricing page, has less room to move terms after you are invested in a candidate.
- Warranty length on direct hires. The industry standard is a 90-day guarantee. Frontline Source Group's 5-Year Placement Warranty is roughly 20 times longer, and it reflects how confident the firm is in its screening. Certain restrictions apply.
- Retention data. Ask what percentage of the firm's placements are still in seat after the first year. Frontline Source Group reports a 98.94% executive placement retention rate against an industry average of roughly 70 percent.
- Independent reviews and awards. Verified third-party reviews on Trustpilot and client and talent satisfaction awards from ClearlyRated are harder to manufacture than website testimonials. Frontline Source Group holds a 5.0 star Trustpilot rating across 683 plus reviews and is a 9-time ClearlyRated Best of Staffing winner for both Client and Talent.
- ASA membership. Membership in the American Staffing Association signals adherence to the association's code of ethics and legal compliance standards for employer-of-record work.

What makes Frontline Source Group different from other staffing firms?
Three things separate Frontline Source Group from the typical staffing firm. First, the 5-Year Placement Warranty on every direct hire, compared with the 90-day guarantee that is standard across the industry. Second, publicly published pricing and 683 plus verified Trustpilot reviews, which together make the firm's terms and track record checkable before a first call. Third, a 22-year record of sustained recognition rather than a single award year: 9 consecutive years on the Forbes Best Professional Recruiting Firms list (2018 to 2026), a 2026 debut at #148 on the Forbes Best Executive Recruiting Firms list, and 9 ClearlyRated Best of Staffing wins for both Client and Talent satisfaction. The firm's tagline, People. Process. Service., describes the operating model: named recruiters, a documented screening process, and accountability after the placement.

Who is the employer of record when I work through a staffing firm?
On a contract or contract-to-hire assignment, the staffing firm is the employer of record. It issues your W-2, pays your wages, withholds and remits payroll taxes, and carries workers' compensation coverage, while the client company directs your daily work.

What is the difference between a staffing firm and a recruiting firm?
A staffing firm offers contract, contract-to-hire, and direct hire services and acts as the employer of record for contract workers.

Frontline Source Group provides all three services through discipline-specific recruiting desks.

Contract-to-hire places the candidate on the staffing firm's payroll for an evaluation period before the employer decides whether to convert the person to a permanent employee.

At Frontline Source Group, every direct hire is backed by the 5-Year Placement Warranty.
