First Time working with Staffing Agency
Hiring a Staffing Agency for the First Time? Here’s Exactly What Phoenix Employers Should Expect
You have always hired employees yourself.
Then something changes.
A large customer comes in.
Several employees leave.
Production increases.
Peak season approaches.
A warehouse adds another shift.
A project starts earlier than expected.
Or management simply realizes that supervisors and HR are spending far too much time trying to keep positions filled.
Someone finally says:
“Maybe we should call a staffing agency.”
If your company has never used one before, the process can seem confusing.
Who employs the temporary worker?
Who handles payroll?
How is the staffing company paid?
Who decides which workers come to your facility?
What happens when someone calls out?
Can you hire a great temporary employee permanently?
And perhaps most importantly:
What should you expect from the staffing agency before you trust it with part of your workforce?
For Phoenix employers considering temporary staffing for the first time, here is how the relationship generally works—and what you should have clear before the first worker arrives.
1. The First Conversation Should Be About Your Business, Not Just Headcount
A first-time employer may call and say:
“I need ten people.”
That's useful information, but it isn't enough to build a good staffing plan.
A staffing company should want to understand what those ten people will actually do.
That conversation may include the type of work, location, schedule, expected assignment length, compensation, working conditions, required qualifications, anticipated overtime, reporting structure, and whether the need is temporary, temp-to-hire, or potentially long-term.
The agency should also understand why the need exists.
Ten employees needed for a three-day project represent a different workforce problem from ten employees needed every week because a company is growing.
Understanding the business problem helps determine the appropriate staffing model.
2. Expect Questions About the Actual Job
Good recruiting starts with an accurate description of the work.
A staffing agency may ask about physical requirements, equipment used, work environment, dress or PPE expectations, previous experience, training, shift hours, breaks, attendance expectations, supervision, and other job-specific requirements.
Those questions aren't unnecessary paperwork.
They help prevent a common staffing failure:
The employee accepts one job and arrives to discover another.
For example, “warehouse associate” could mean picking small products in a climate-controlled facility or moving heavier materials in a very different environment.
The title alone doesn't tell the candidate enough.
The more accurately the agency understands the assignment, the more accurately it can recruit.
3. The Agency Should Understand the Worksite Too
The physical location matters.
Where should workers park?
Which entrance should they use?
Who do they report to?
What happens when they arrive?
Is the work indoors, outdoors, or both?
Are there site-specific procedures?
Does the shift start extremely early?
Is the facility difficult to locate?
These details may sound minor until ten new employees are standing in the wrong parking lot at 5:55 AM.
For Phoenix-area employers, geography also affects recruiting.
A facility in Tolleson may draw from a different practical labor pool than one in Mesa, Buckeye, Goodyear, Chandler, Glendale, or central Phoenix.
The job's location is part of the job.
4. You'll Need to Decide Which Staffing Model Fits the Need
Not every staffing request should be structured the same way.
For many employers, the first decision is whether the need is temporary, temp-to-hire, or a different type of recruiting arrangement.
Temporary staffing can make sense for demand spikes, projects, absences, events, backlogs, seasonal needs, or other variable workforce requirements.
Temp-to-hire can make sense when there is a genuine permanent opportunity but both employer and employee would benefit from evaluating the relationship through actual work before a permanent hiring decision.
The appropriate model depends on the position and business objective.
Don't automatically choose temp-to-hire simply because it sounds safer.
And don't label a genuinely permanent position “temporary” indefinitely simply to avoid making a hiring decision.
Clarity helps both sides.
5. Then Comes Pricing: Pay Rate, Bill Rate and Markup
This is often the part first-time staffing clients misunderstand.
The employee's hourly pay rate and the client's staffing bill rate are not the same thing.
For illustration only, suppose a temporary employee earns:
$20 per hour
and the staffing company's bill rate is:
$30 per hour.
The $10 difference is not automatically agency profit.
The staffing company's pricing has to support the costs and responsibilities included in its service arrangement, which can include employee compensation and applicable employer-side payroll costs, workers' compensation coverage, recruiting, onboarding, administration, insurance, account servicing, technology, operating expenses, and the agency's margin.
The actual structure varies by staffing provider, position, risk classification, client requirements, and agreement.
This is why employers should compare what the price includes, not simply which agency quotes the smallest markup.
6. Understand Markup Before Comparing Quotes
Markup and gross margin are frequently confused.
Using the illustrative example above:
A $20 pay rate and $30 bill rate would represent a 50% markup on the pay rate.
That does not mean the agency has a 50% profit margin.
Employers comparing proposals should ask each agency to explain terminology and what services and responsibilities are included.
A cheaper bill rate can become expensive if the workforce repeatedly fails to arrive, turns over rapidly, performs poorly, or requires constant replacement.
7. Review the Service Agreement Before Workers Are Requested
Before the relationship begins, the parties should understand the actual agreement governing it.
This may address matters such as pricing, payment terms, timekeeping, overtime billing, invoicing, insurance requirements, employee conversion terms, replacement procedures, responsibilities of each party, and other conditions relevant to the relationship.
Read it.
Don't wait until you want to permanently hire a temporary employee to ask whether conversion terms exist.
Don't wait until an invoice arrives to ask how overtime is billed.
Don't wait until a no-show occurs to ask how replacements are handled.
The best time to understand the rules is before the first assignment begins.
8. Understand Who Employs the Temporary Worker
In a typical staffing arrangement, the staffing agency is generally the temporary worker's employer for payroll purposes and handles responsibilities assigned to it under the staffing relationship, such as paying the employee and applicable payroll administration.
However, using a staffing agency does not mean the client can ignore workplace responsibilities.
The client still controls important aspects of the actual work environment and day-to-day assignment, and legal responsibilities can depend on the circumstances and applicable law.
Employers should not assume:
“They're the agency's employee, so nothing is our responsibility.”
That is too simplistic.
Each party should understand its responsibilities under the agreement and applicable requirements.
9. Workers’ Compensation and Safety Should Be Discussed Upfront
Staffing pricing and placement can be affected by the actual work being performed.
That is another reason job descriptions need to be accurate.
A staffing company needs to understand what employees will really be doing rather than receiving a generic title that doesn't reflect the assignment.
Likewise, the client should maintain an appropriate workplace and provide required site-specific instruction, supervision, equipment, procedures, and safety measures applicable to the work.
If the job changes materially, communicate with the staffing agency.
Don't hire someone for one assignment and quietly move them into substantially different work without discussing it.
10. Recruiting Begins Once the Assignment Is Defined
After the position, requirements, pricing, and relationship are established, recruiting can begin.
Depending on the assignment and staffing company, candidates may come from existing applicant pools, previous successful workers, referrals, recruiting campaigns, job advertising, outreach, or other sources.
Speed depends on the actual requirement.
Finding several general laborers for a straightforward assignment may be different from recruiting a large group for an overnight shift or finding workers requiring specialized experience.
This is why an honest staffing company shouldn't automatically promise:
“We can fill anything tomorrow.”
Sometimes rapid staffing is possible.
Sometimes more time is required.
11. Ask How Candidates Are Matched to Your Assignment
Employers should understand enough about the agency's recruiting process to know what they're buying.
How does the agency determine that someone is appropriate for the job?
How are schedule and location confirmed?
How are required qualifications handled?
How does the agency communicate working conditions?
What happens when a candidate says the job isn't right for them?
A good recruiting process isn't about convincing every applicant to accept.
It should also help unsuitable candidates decline before they become unsuccessful employees.
12. Screening Should Match the Actual Position
Screening practices can vary by role, employer requirements, staffing company, applicable law, and the nature of the assignment.
The important principle is that requirements should be identified before recruiting is completed.
If a position requires a particular qualification, credential, screening step, or experience level, communicate it upfront.
Adding major requirements at the last minute can delay staffing and create unnecessary rework.
Employers should also avoid requirements that aren't actually relevant to the position merely because:
“That's what we've always requested.”
Every requirement can affect the candidate pool.
Know why it exists.
13. Day 1 Is Where the Staffing Plan Meets Reality
A spreadsheet may say:
20 workers confirmed.
At 6:00 AM, what matters is:
How many actually arrived ready to begin?
That's why first-day planning matters.
Workers should know where to go, when to arrive, who to ask for, what the assignment involves, and what they need to bring or wear as appropriate.
The client should know workers are coming and have a process for receiving them.
A staffing company can successfully recruit 20 people and the client can still have a terrible first day if nobody is prepared to onboard them.
14. Your Company Needs Onboarding Capacity Too
Suppose all 20 workers arrive.
One supervisor is responsible for checking everyone in, explaining the facility, handling required site-specific orientation, assigning work, answering questions, and simultaneously running the normal operation.
The staffing agency filled the order.
The client created a bottleneck.
Before requesting a large group, ask:
How many new employees can we effectively receive and train at once?
Sometimes staggered starts or smaller onboarding groups may work better, depending on the operation.
Hiring capacity and training capacity aren't the same thing.
15. Timekeeping Needs to Be Accurate From the Beginning
Temporary staffing typically requires a reliable way to record and approve hours worked.
The exact system varies.
Whatever method is used, establish the process before payroll and invoicing deadlines arrive.
Who reviews time?
Who approves it?
What happens when hours are wrong?
How are missed punches handled?
How is overtime identified?
How quickly must corrections be submitted?
Small timekeeping errors multiplied across dozens of employees can become significant administrative problems.
A clear process protects both the worker and the client.
16. Understand How Invoicing Works
The employer should know how frequently invoices are issued, what information appears on them, who receives them, how disputes are handled, what the payment terms are, and how different types of hours are billed under the agreement.
This is especially important for companies with multiple departments, job codes, shifts, locations, or projects.
Good invoice detail can make staffing costs easier to allocate internally.
Poor administrative setup can make a good staffing relationship unnecessarily frustrating.
17. Don't Wait Until Someone Fails to Discuss Replacements
Before the first worker starts, ask:
What happens if someone doesn't show up?
No staffing agency can realistically guarantee that human beings will never become sick, experience emergencies, have transportation problems, or make poor decisions.
What matters is the process.
Who does the client contact?
How does the agency verify the absence?
When does replacement recruiting begin?
How will the agency communicate status?
At what point is a replacement no longer useful for the remaining shift?
Those expectations should be established before 6:05 AM on the day a worker is missing.
18. Give the Agency Performance Feedback
This is where a staffing relationship can become significantly better over time.
Suppose five workers are assigned.
Three are excellent.
One is average.
One isn't a good fit.
Tell the staffing company.
Without feedback, the agency may assume everyone performed equally.
With feedback, it can begin identifying what successful workers have in common and, where appropriate, prioritize proven employees for future assignments.
The goal is to make Order #10 smarter than Order #1.
19. Ask for Successful Workers Again
If your business has recurring temporary needs, continuity can be valuable.
A worker who has already succeeded at your facility may know the commute, entrance, supervisor, schedule, basic process, expectations, and working environment.
When practical and when the employee is available, bringing that person back can reduce some of the uncertainty associated with starting someone completely new.
Over time, a company may develop a pool of preferred temporary workers.
Temporary doesn't have to mean unfamiliar.
20. If You Want to Hire a Temp Permanently, Check the Agreement
One of the best outcomes of temporary staffing can be discovering someone you want on your permanent team.
That's a win.
But employers should understand conversion terms before reaching that point.
The agreement may contain conditions relating to how or when a temporary employee can transition to the client's payroll.
Those terms vary by staffing company and agreement.
Ask upfront.
Then when a great employee emerges, everyone knows the process.
21. Measure the Staffing Agency by More Than Bill Rate
Once the relationship has operated for a while, evaluate outcomes.
A useful staffing scorecard might look like this:
MetricWhat It Tells YouWorkers RequestedYour demandWorkers ScheduledFill performanceWorkers ReportingDelivered capacityShow RateAttendance reliabilityOn-Time ArrivalShift readinessEarly RetentionAssignment stabilityReplacement ResponseRecovery capabilityReturning WorkersWorkforce continuitySupervisor FeedbackPerformance qualityConversionsTemp-to-hire outcomes where applicableInvoice AccuracyAdministrative qualityCommunicationService responsiveness
The lowest markup doesn't necessarily create the lowest total workforce cost.
Likewise, the fastest fill doesn't necessarily create the best workforce.
Measure what actually happens after people arrive.
22. The Relationship Should Improve Over Time
A staffing agency should learn your business.
Not proprietary details it doesn't need.
But enough operational knowledge to recruit more intelligently.
Which shifts are hardest to fill?
Which workers succeed?
Where do employees tend to live?
What causes people to leave?
Which job descriptions produce good matches?
What feedback are workers providing?
When does demand normally increase?
Which supervisors need the most communication?
What does your company consider excellent performance?
Every assignment creates information.
A mature staffing relationship uses it.
How Flat Staffing Approaches a New Client Relationship
Flat Staffing has served the Phoenix Valley since 2018, supporting employers across warehousing, logistics, distribution, manufacturing, automotive operations, events, construction-related general labor, and other temporary workforce needs.
When a new company contacts us, we don't want to know only:
“How many workers?”
We want to understand enough about the operation to help determine what the business actually needs.
Sometimes that means temporary workers.
Sometimes temp-to-hire.
Sometimes the employer may discover that the real issue isn't headcount at all.
The more clearly the problem is defined, the better the workforce solution can become.
And once employees begin working, communication shouldn't stop.
Client feedback and employee feedback can help improve the next assignment.
Leadership Behind Flat Staffing
Flat Staffing is led by Nino Mihilli, and first-time staffing relationships reflect a simple business principle:
A good partnership should become more valuable as both sides learn.
The first staffing order contains uncertainty.
By the fifth, we should know more.
By the twentieth, we should know considerably more.
Which employees succeed.
Which schedules are difficult.
Which recruiting approaches work.
Where communication breaks down.
What the client values.
What workers experience.
If a staffing relationship processes the same mistakes repeatedly without learning, volume alone hasn't made it better.
The goal isn't simply becoming another vendor.
It's becoming a workforce partner that understands the operation well enough to create value.

The Bottom Line
Hiring a staffing agency for the first time shouldn't feel mysterious.
The process generally begins by defining the workforce problem and actual assignment. From there, the employer and agency establish the staffing model, pricing, agreement, responsibilities, recruiting requirements, communication process, timekeeping, invoicing, and expectations for what happens after employees arrive.
But choosing a staffing company shouldn't come down to:
“Who gave me the lowest markup?”
Ask what happens next.
Who are you recruiting?
How do you prepare them?
What happens when someone doesn't arrive?
How do you handle feedback?
Can successful workers return?
How do you measure performance?
What happens when I want to hire someone permanently?
And most importantly:
Will you understand my business better six months from now than you do today?
Because a staffing agency can provide workers.
A strong staffing relationship should help you build a better workforce.
Frequently Asked Questions
How does a staffing agency work for an employer?
The specific arrangement varies, but a staffing agency generally recruits and employs temporary workers for payroll purposes and assigns them to client companies under an agreed staffing arrangement. The agency and client each have responsibilities, which should be defined in their agreement and handled according to applicable requirements.
How much does a staffing agency charge in Phoenix?
There is no universal staffing-agency markup or bill rate. Pricing can vary based on employee pay, job duties, workers' compensation classification, assignment requirements, volume, screening, service requirements, risk, and other factors. Employers should compare the complete service and expected workforce outcomes rather than markup alone.
Who pays a temporary employee?
In a typical temporary staffing arrangement, the staffing agency pays its temporary employees. The client pays the staffing agency according to the agreed bill rate and invoicing terms.
Can I hire a temporary worker permanently?
Often there is a process for doing so, but conversion terms vary by staffing agreement. Employers should review those terms before the assignment begins rather than waiting until they find someone they want to hire.
What should I ask before hiring a staffing agency?
Ask about recruiting, candidate matching, pricing, bill rates, overtime, timekeeping, invoicing, insurance, assignment responsibilities, no-show procedures, replacements, communication, conversion terms, performance measurement, and how the agency handles recurring successful workers.
