Employment Agency

Employment agencies is a broader term covering temp, contract, and permanent placements.

An employment agency is a third-party firm that connects employers with job candidates, handling sourcing, screening, and placement across temporary, contract, and permanent roles. Employment agencies earn fees through contingency placements (paid on hire) or retained engagements (paid upfront). At enterprise scale, agencies operate within managed service programs (MSP) coordinated through vendor management systems. Also called: staffing agency, placement agency.

Types of employment agencies

Not every agency serves the same use case. Enterprise HR teams typically engage four distinct types.

Temporary staffing agencies supply workers for defined assignments, from days to several months. The agency acts as the employer of record, handling payroll, benefits, and workers’ compensation. Volume fluctuations, seasonal peaks, and project coverage are the primary drivers. According to the American Staffing Association, U.S. staffing companies employed an average of two million temporary and contract workers per week in Q4 2025.

Direct-hire agencies (also called permanent placement agencies) identify full-time employees for roles where the client company takes on the employment relationship at hire. Fee is typically charged as a percentage of first-year salary, paid once the candidate starts. These agencies handle sourcing and initial screening, but the legal employer responsibility shifts fully to the client.

Executive search firms specialize in senior and C-suite recruitment. They operate almost exclusively on a retained basis, meaning fees are paid in installments regardless of placement outcome. Assignments are confidential, research-intensive, and can run 60 to 120 days.

Temp-to-hire agencies offer a trial period: the worker is on the agency’s payroll for a set number of hours, then converts to a permanent employee if the client and candidate both agree. This model reduces permanent hiring risk and is a standard option in high-volume operational roles.

Employment agency vs staffing agency vs recruitment firm

These three terms are used interchangeably in casual conversation, but they describe meaningfully different service models. Misclassifying them leads to wrong vendor selection, misaligned fee expectations, and compliance gaps.

Employment agencies sit at the broadest point in this taxonomy. A single agency vendor can cover temp, contract, and permanent placements, which is why large enterprises often use employment agencies as the catch-all vendor category inside an MSP program while maintaining separate specialist relationships for executive search.

Fee structures

Understanding fee mechanics protects procurement conversations and prevents surprise costs.

Hourly markup applies to temporary and contract placements. The agency bills the client a blended hourly rate that includes the worker’s pay, payroll taxes, benefits, workers’ compensation insurance, and the agency’s margin. Typical markups range from 40 to 75 percent over the worker’s base pay rate, depending on skill category and market.

Contingency placement fees apply to direct-hire assignments. The agency earns a fee, typically 15 to 25 percent of the candidate’s first-year base salary, paid only if the candidate is hired and remains employed past a short guarantee period (30 to 90 days). No placement means no fee.

Retained search fees apply to executive and highly specialized roles. The total fee is 25 to 35 percent of first-year compensation, split into three installments: at engagement, at candidate presentation, and at offer acceptance. Retained engagements buy exclusive focus and a broader, more methodical search.

Volume discounts and rate cards are standard in enterprise programs. When managing 10 or more agency relationships, negotiating a master rate card with tiered markup schedules by job category (administrative, technical, professional, executive) is common practice. Rate cards anchored in a VMS enforce compliance automatically.

Compliance: EEOC, FCRA, and co-employment

Compliance risk is where poorly managed agency relationships create enterprise liability.

EEOC joint employer exposure. The Equal Employment Opportunity Commission provides explicit guidance that anti-discrimination statutes apply to temporary and contingent workers placed by staffing agencies. Both the agency and the client company can be held jointly liable if discriminatory practices occur, including discriminatory job orders, screening criteria that disparate-impact a protected class, or hostile work environment claims arising on the client’s premises. Written job orders should be specific, skills-based, and free of language that could signal protected-class preferences.

FCRA requirements. When an agency runs background checks or credit inquiries on candidates before placement, the Fair Credit Reporting Act governs disclosure, consent, and adverse action procedures. Enterprises using agency-sourced background reports must confirm the agency’s screening process complies, including candidate authorization forms, pre-adverse action notices, and dispute rights. The Consumer Financial Protection Bureau’s 2024 guidance extended FCRA coverage to algorithmic scoring tools used in hiring decisions, including many ATS-integrated assessment products.

Co-employment risk management. Temp and contract workers on agency payrolls can claim employee status with the client if behavioral control indicators are present, such as the client setting work schedules, directing day-to-day tasks, providing equipment, or granting long-term access to internal systems. Standard mitigation practices include limiting assignment duration (typically to 18 months), routing all work direction through a statement of work, and avoiding integration of temp workers into permanent employee programs (benefits portals, all-hands, performance reviews).

State-level variation. California AB5, New York’s wage theft prevention laws, and Illinois’s Day and Temporary Labor Services Act each impose additional requirements on temp agency relationships. Enterprise HR teams with multi-state footprints should audit agency contracts annually against each state’s current requirements.

Managing agencies at enterprise scale: MSP and VMS programs

Ad-hoc agency management does not scale past a few dozen annual placements. When contingent workforce spend exceeds $5 to $10 million annually, a managed service program (MSP) is the standard operating model.

An MSP is a third-party provider, often itself a large staffing firm, that manages the entire vendor ecosystem on behalf of the client. The MSP consolidates requisition management, agency vetting, rate card enforcement, SLA tracking, and invoice consolidation. The client gains a single point of accountability; agencies gain structured access to a high-volume buyer.

A vendor management system (VMS) is the technology layer. Requisitions flow from the client’s ATS or HRIS into the VMS, agencies submit candidates through the VMS portal, timesheets are approved in the VMS, and invoicing is automated. SAP Fieldglass leads the market by spend volume; Beeline is the leading challenger, with faster typical implementation timelines of four to nine months versus six to twelve months for Fieldglass. Both platforms support integration with Workday, SAP SuccessFactors, and Oracle HCM.

Key agency performance metrics to track inside a VMS program include: submittal-to-interview ratio, time-to-fill by job category, offer acceptance rate, assignment completion rate, co-employment incident rate, and diversity supplier spend percentage.

Direct sourcing, where enterprises build their own talent pools of pre-vetted candidates and engage agencies only to supplement, is growing as a cost reduction strategy. AI-enabled private talent clouds are increasingly integrated into VMS platforms to allow program owners to present internal re-engagement candidates before releasing requisitions to the agency supply chain.

Evaluating an employment agency for enterprise use

Before adding a new agency to your vendor panel, run against this checklist.

Compliance posture. Does the agency have documented EEOC-compliant job order procedures? Is their background screening FCRA-certified? Can they provide a co-employment liability insurance certificate?

Assessment practices. How does the agency screen candidates beyond resume review? Pre-employment skills assessments reduce placement failure rates. Agencies that integrate structured assessments for role-specific competencies before submitting candidates deliver measurably better quality of hire than those relying on resume and phone screen alone.

Technology integration. Can the agency accept requisitions from and submit candidates into your VMS? Do they have API connectivity to SAP Fieldglass, Beeline, or Coupa?

Diversity and inclusion. Does the agency report diversity metrics on candidate slates and placements? EEOC audit trails require documented supplier diversity tracking for large employers.

Guarantees and replacement terms. What is the refund or replacement policy if a placed candidate departs in the first 30, 60, or 90 days? Are guarantees tied to invoice payment terms?
