What Is a Staffing Agency?
A staffing agency is a company that recruits and supplies workers to client organizations for temporary, contract, temporary-to-hire, or permanent roles.
In many temporary staffing arrangements, the agency employs or engages the worker, handles agreed employment administration, and assigns that person to work for a client.
The client typically directs the worker’s day-to-day activities within the responsibilities agreed between the parties.
The term staffing agency is often used broadly for firms that provide:
- Temporary workers
- Contractors
- Temporary-to-hire workers
- Direct-hire recruitment
The exact employment relationship, legal responsibilities, and commercial structure depend on the service model, contract, worker classification, and jurisdiction.
Staffing agencies at a glance
Staffing agencies typically:
- Recruit workers for client assignments and permanent vacancies
- Maintain candidate pools for recurring and urgent hiring demand
- Screen candidates for skills, availability, location, pay, and assignment requirements
- Coordinate onboarding and documentation
- Manage schedules and assignment communication
- May employ temporary workers and process payroll
- Earn revenue through staffing margins, markups, contract fees, or placement fees
- Share certain responsibilities with clients where joint employment applies
How does a staffing agency work?
A staffing agency typically manages more than candidate sourcing.
The process can continue from the initial client requirement through the worker’s assignment, payroll, billing, and eventual redeployment.
1. Win and qualify the client requirement
The staffing agency first agrees the details of the assignment with the client.
This may include:
- Job role
- Number of workers required
- Work location
- Shift schedule
- Start date
- Assignment duration
- Pay rate
- Client bill rate
- Required skills
- Supervision
- Safety responsibilities
- Screening requirements
- Onboarding requirements
- Time approval
- Conversion terms
- Service levels
A complete staffing order should describe the actual work environment, not just the job title.
Recruiters may also need to understand:
- Physical requirements
- Equipment used
- Workplace hazards
- Overtime expectations
- Required licenses or credentials
- Manager contacts
- What happens if a worker is absent
- What happens if a worker is unsuitable
2. Recruit and build an available worker pool
Staffing recruiters may source candidates through:
- Previous workers
- Referrals
- Job applications
- Job boards
- Community channels
- Professional networks
- Direct outreach
Because staffing demand can be time sensitive, candidate availability is particularly important.
An available worker record may include:
- Confirmed start date
- Shift preferences
- Travel radius
- Pay expectations
- Work authorization
- Credentials
- Previous assignments
- Availability status
Maintaining accurate candidate information can help staffing agencies respond more quickly when clients have urgent requirements.
3. Screen and clear workers
The agency evaluates whether each worker meets the job-related and assignment-specific requirements.
Depending on the role and client, screening may include:
- Interviews
- References
- Background checks
- Drug testing
- License verification
- Safety orientation
- Work samples
- Client-specific documentation
Requirements vary by assignment and jurisdiction.
The agency should clearly record:
- Which checks are required
- Who owns each check
- Who reviews the result
- When documents expire
- What happens if the assignment changes
4. Submit or assign candidates
The next step depends on the staffing service.
For direct hire, the staffing agency usually presents candidates to the client for selection.
For temporary or contract staffing, the agency may confirm the worker’s assignment once required screening and client approval are complete.
Workers should receive accurate assignment information, including:
- Job responsibilities
- Client name
- Location
- Schedule
- Pay
- Assignment duration
- Reporting contact
- Dress requirements
- Equipment requirements
- Time-entry process
Clear assignment information can reduce misunderstandings before a worker starts.
5. Manage the active assignment
For temporary and contract staffing, the agency’s work continues after the worker starts.
The agency may track:
- Attendance
- Time worked
- Assignment extensions
- Rate changes
- Schedule changes
- Workplace incidents
- Client feedback
- Worker feedback
- Redeployment opportunities
- Assignment end dates
Recruiters and staffing operations teams need to stay in contact with both workers and clients throughout the assignment.
6. Process time, payroll, and billing
In many temporary staffing models, approved worker time feeds directly into payroll and client billing.
The agency may need to calculate and track:
- Regular hours
- Overtime
- Worker pay
- Client billings
- Payroll taxes
- Deductions
- Benefits
- Other employment costs
Accurate time and rate information is critical because errors can affect both worker pay and client invoices.
7. End, extend, convert, or redeploy workers
A staffing assignment can end in several ways.
It may:
- Finish as planned
- End early
- Be extended
- Convert into permanent employment
- Lead to another assignment
The agency should record information such as:
- Assignment end reason
- Final approved time
- Conversion fee, if applicable
- Updated worker availability
- Client feedback
- Worker feedback
- Follow-up actions
Where possible, staffing firms may also redeploy successful workers into another assignment.
Main staffing agency services
Staffing agencies can operate across several different service models.
| Service | Worker relationship | Client use | Agency revenue |
|---|---|---|---|
| Temporary staffing | Worker is assigned for a limited period under the agreed employment model | Cover absences, seasonal peaks, projects, or fluctuating demand | Spread between client billings and direct worker costs |
| Contract staffing | Worker provides services for a fixed term or project | Access specialist capacity or defined-duration support | Margin, markup, or contract fee |
| Temporary-to-hire | Worker begins on assignment with the possibility of permanent client employment | Evaluate mutual fit before making a permanent decision | Staffing revenue plus any agreed conversion fee |
| Direct hire | Candidate becomes an employee of the client | Fill a permanent position | Placement fee triggered under the agreement |
A staffing firm may offer one or several of these services depending on its market and operating model.
Example of a staffing agency workflow
Imagine a food manufacturer needs 24 packaging workers for a ten-week seasonal production increase.
The client operates two shifts and provides the staffing agency with:
- Production requirements
- Job duties
- Pay rates
- Bill rates
- Shift times
- Overtime expectations
- Site-access requirements
- Safety information
- Supervisor contacts
The staffing team first reviews its existing available-worker pool.
Recruiters contact previous workers with strong attendance records and then source additional candidates.
New applicants are screened for:
- Schedule availability
- Transportation
- Work authorization
- Job requirements
- Start date
The agency and client also document which onboarding and safety responsibilities belong to each party.
Workers receive assignment details and general preparation from the agency.
The client provides site-specific information such as:
- Workplace orientation
- Hazard information
- Work instructions
- Required equipment
Twenty-four workers begin the assignment, while four additional workers remain available as backups.
The staffing agency monitors attendance and replaces two workers who leave early.
Approved time then feeds into payroll and client billing.
Near the eighth week, the client decides to:
- Extend 12 assignments
- Hire three workers permanently
The conversion follows the terms agreed in the staffing contract.
The success of the staffing operation depends not only on filling the initial positions but also on:
- Worker communication
- Attendance
- Time accuracy
- Assignment management
- Fast replacement
- Redeployment
Staffing agency vs. recruitment agency
The terms staffing agency and recruitment agency are sometimes used interchangeably, but their operating models can differ.
| Point | Staffing agency | Recruitment agency |
|---|---|---|
| Core service | Supplies temporary, contract, temporary-to-hire, and permanent talent | Finds candidates for client vacancies, commonly permanent roles |
| Worker relationship | May employ or engage workers assigned to client organizations | Candidate commonly becomes an employee of the client after placement |
| Operating cycle | Can continue through assignment management, time, payroll, billing, and redeployment | Commonly runs from client brief through accepted hire and follow-up |
| Revenue | Staffing margin, markup, contract fee, or placement fee | Placement fee or retained fee |
| Main records | Orders, availability, assignments, shifts, rates, time, payroll status, compliance | Jobs, candidates, submissions, interviews, offers, placements, and fees |
Recruitment agency can also act as a broader umbrella term.
Some firms provide both staffing and permanent recruitment services.
The distinction matters when evaluating:
- Contracts
- Technology
- Cash flow
- Worker responsibilities
- Compliance requirements
- Performance metrics
How do staffing agencies make money?
Temporary and contract staffing revenue commonly comes from the amount the agency bills the client for work performed by assigned workers.
The agency then pays the worker and covers the applicable employment costs under the arrangement.
The remaining amount contributes toward the agency’s operating expenses and profit.
Two important staffing metrics are markup and gross margin.
Staffing markup
Markup percentage = (client bill rate ? worker pay rate) / worker pay rate × 100
For example, if:
- Worker pay rate = $20 per hour
- Client bill rate = $30 per hour
The spread is $10.
The markup is:
($30 ? $20) / $20 × 100 = 50%
Staffing gross margin
Gross margin percentage = (client billings ? direct worker costs) / client billings × 100
Using the same simplified example:
($30 ? $20) / $30 × 100 = 33.3%
Markup and gross margin are not the same.
Staffing agencies need to define which measure they use when pricing, forecasting, and reporting.
They may also need to account for costs such as:
- Overtime
- Holiday pay
- Payroll taxes
- Insurance
- Benefits
- Expenses
- Conversion fees
- Rebates
- Credits
- Rate changes
Cash flow also matters.
A staffing firm may need to pay workers before the client pays its invoice, which can create significant working-capital requirements.
How to evaluate a staffing agency
Staffing agency performance should be evaluated across delivery, workforce management, client service, and financial performance.
Useful metrics include:
- Fill rate
- Time from confirmed order to worker start
- Assignment start rate
- First-day attendance rate
- Worker cancellation rate
- No-show rate
- Assignment completion rate
- Assignment extension rate
- Temporary-to-permanent conversion
- Worker redeployment rate
- Client feedback
- Worker feedback
- Timecard submission accuracy
- Timecard approval accuracy
- Payroll exception rate
- Invoice exception rate
- Gross margin by client
- Gross margin by order
- Gross margin by role
- Gross margin by branch
- Days sales outstanding
- Overdue receivables
- Safety incidents
- Training completion
- Credential expiry exceptions
Metrics should be segmented by comparable service, client, location, shift, and period where useful.
For example:
- A high fill rate may hide poor worker retention
- A strong markup may hide overtime leakage
- High revenue may hide poor client payment speed
- Fast starts may hide weak worker attendance
The full staffing operation needs to be considered together.
Common staffing agency mistakes
Accepting an incomplete staffing order
Missing information about shifts, hazards, supervision, pay, screening, or time approval can create operational problems later.
Recruiters should qualify the full assignment before sourcing workers.
Treating availability as qualification
A worker being available to start quickly does not automatically mean they are qualified.
Recruiters should still verify:
- Required skills
- Credentials
- Transportation
- Schedule reliability
- Assignment requirements
Availability and qualification are different criteria.
Losing contact after placement
Temporary staffing requires active assignment management.
The staffing agency should continue to:
- Confirm worker starts
- Monitor attendance
- Capture feedback
- Communicate changes
- Track assignment end dates
- Plan extensions or redeployment
Mixing up markup and margin
Markup and gross margin use different calculations.
Using one term while calculating the other can create incorrect pricing and profitability decisions.
Staffing teams should define both formulas consistently.
Keeping payroll and recruiting records separate
Disconnected candidate, assignment, rate, time, and payroll data can create:
- Manual corrections
- Billing disputes
- Payroll errors
- Reporting problems
Staffing firms should define clear ownership and reconciliation points between systems and teams.
Leaving shared responsibilities unclear
Staffing agreements and operating processes should clearly define responsibility for areas such as:
- Screening
- Supervision
- Safety
- Training
- Incident reporting
- Time approval
- Worker communication
- Recordkeeping
Legal obligations can vary by jurisdiction and cannot always be reassigned solely through contract.
Staffing agency responsibilities
A staffing agency’s responsibilities depend on the jurisdiction and operating model.
Depending on the arrangement, responsibilities may include:
- Worker classification
- Wage and hour compliance
- Payroll taxes
- Benefits
- Insurance
- Worker records
- Required notices
- Leave administration
- Candidate screening
- Safety communication
- Data protection
In some temporary staffing arrangements, the staffing agency and client may share certain employment or workplace responsibilities.
The exact responsibilities depend on the facts of the arrangement and applicable law.

Build a more connected staffing operation
A staffing agency’s work does not end when a candidate accepts an assignment.
Successful staffing requires coordination across client requirements, worker availability, screening, assignment management, time, payroll, billing, and redeployment.
Review one active staffing order from client intake through payroll and billing.
Identify every point where missing information, disconnected records, or unclear ownership could create a problem for the worker, the client, or the agency’s margin.
