Staffing Agency vs Recruiting Agency: What Is the Difference?

A staffing agency supplies temporary and contract workers, stays on as the employer of record during the assignment, and handles payroll, benefits, and workers’ comp. A recruiting agency finds permanent employees for your company, collects a one-time placement fee when the person accepts, and walks away. That is the textbook answer. It is also about ten years out of date for anyone hiring in tech.

I got a call last month from a VP of Engineering in Irvine who wanted to “hire a recruiter.” What he actually needed was three contract QA engineers starting in two weeks for a compliance push, with the option to convert one or two of them afterward. That is staffing. Nobody told him the industry name for that. He just knew he needed people fast and did not want to put them on his headcount until the project proved out. We set up the contracts through KORE1’s IT staffing team, billed weekly, and he converted two of the three to permanent at month four. By the end he had used a staffing agency, a recruiting agency, and a contract-to-hire arrangement, all through the same firm, all on the same engagement. The labels did not matter. The structure did.

Gregg Flecke, business development at KORE1. We are a staffing and recruiting firm, which means we benefit when you use either service. I am going to explain both models honestly, including the parts where you do not need us at all.

What a Staffing Agency Actually Does

Here is how it works mechanically. The staffing agency puts the worker on its own W-2 payroll, carries the benefits and workers’ comp, and assigns that person to your site for a set period. You pay the agency a bill rate every week. The agency pays the worker a lower pay rate. The gap between those two numbers is how the agency makes money.

That margin covers more than you think. Workers’ comp insurance, employer-side FICA, state unemployment tax, liability coverage, the recruiter’s time, and the agency’s operating costs all sit inside that spread. The American Staffing Association reported that U.S. staffing companies employed an average of roughly two million temporary and contract workers per week in 2025, with industry sales exceeding $28 billion per quarter. Those are not small-time temp shops. That is a labor infrastructure.

Typical markup runs 25% to 50% depending on the skill level and risk profile of the role. A warehouse associate might carry a 30% markup. A senior cloud engineer on a six-month infrastructure migration? Closer to 40% to 45%, because the agency is carrying a higher pay rate and the replacement cost if the person quits mid-project is brutal.

When staffing makes sense:

• You need someone working next week, not next quarter
• The project has a defined end date, or you are not sure it will survive budget review
• Headcount is frozen but the work is not
• You want to evaluate someone’s actual output before committing to a permanent offer

When it does not: if you already know you want this person for the long haul and the role is funded permanently, you are paying a weekly margin you do not need to pay. Go direct hire.

What a Recruiting Agency Does

A recruiting agency, sometimes called a placement firm or headhunter, finds permanent employees for your organization. The worker goes on your payroll from day one. The fee is a one-time charge, usually somewhere between 18% and 25% of whatever the new hire’s first-year salary ends up being, and once the person starts, the agency’s involvement is mostly over. If the hire flames out inside 60 to 90 days, which happens, the agency either reruns the search for free or gives back a prorated cut of the fee. That is the guarantee window, and you should always negotiate it before signing.

Two models exist here, and confusing them costs companies time.

Contingency search means the agency only gets paid if you hire their candidate. No placement, no fee. The agency is taking the risk. The trade-off is that contingency recruiters are usually working five to ten searches at a time, and the one with the most responsive hiring manager gets the most attention. If you go dark for a week, your search quietly drops down the priority list.

Retained search is different. You pay a portion of the fee upfront, usually a third, a second installment at the shortlist stage, and the remainder on placement. The agency commits dedicated time to your search. This model makes sense for senior or executive roles where the candidate pool is small and the search requires significant outreach to passive talent. Below $120K base, most companies do not need retained. Above $180K, most should seriously consider it.

The Bureau of Labor Statistics classifies staffing and recruiting firms together under NAICS 561300, Employment Services, which tells you something about how blurry the line actually is from a regulatory perspective. The government does not draw the same hard boundary between these two businesses that blog posts do.

When recruiting makes sense: the role is permanent, the person will be on your payroll, and you need help sourcing or screening candidates you cannot reach through your own channels. Especially true for specialized technical roles where the best candidates are not actively job hunting.

When it does not: if you have a strong internal recruiting team and the role is not hard to fill, the 20% fee is money you did not need to spend. A direct hire staffing engagement through an agency is worth the fee when your own pipeline is dry. Not when it is full.

The Comparison, Without the Fluff

Every article ranking for this keyword has a table. Fine. Here is ours, with the row about what happens when it goes wrong, which nobody else includes.

The table is useful. It is also misleading in one important way. It implies a clean binary. Staffing on one side, recruiting on the other, pick one. In practice, the majority of tech hiring engagements we run at KORE1 start as one model and shift to another mid-search. The client calls for contract help, decides three weeks in that the person is too good to lose, and asks about converting to permanent. Or the client calls for a permanent search, realizes the budget will not clear for six weeks, and asks if we can start the person as a contractor while the req gets approved. The models blend.

Contract-to-Hire: The Part Most Comparison Articles Leave Out

Contract-to-hire sits between staffing and recruiting, and for tech roles specifically, it has become the default engagement model over the last three years. The worker starts on the agency’s payroll as a contractor, works for an evaluation period of 90 days to six months, and then converts to your permanent headcount if both sides want to continue.

The fee mechanics work like this. During the contract period, you pay the same bill rate markup as a standard staffing arrangement. At conversion, there is a buyout fee. Most agencies price it between 10% and 20% of the projected annual salary, minus a credit for the weeks you already paid a margin on. The longer the contract period, the lower the conversion fee. Some agencies, KORE1 included, credit a portion of the margin already paid during the contract phase toward the conversion fee, which means a six-month contract-to-hire often costs less total than a direct placement at 20%.

Why is this the dominant model in tech? Two reasons.

First, a resume does not tell you if a senior DevOps engineer can actually run an incident response at 2 a.m. or if they just listed “on-call experience” because someone told them to. Ninety days of real work does. We had a client in San Diego, mid-size SaaS company, running a Kubernetes migration off a legacy VM deployment. They brought in a DevOps contractor through us at $78/hour. Good resume. Strong interview. Six weeks in, the team lead called me and said the contractor had rewritten the Terraform modules without telling anyone and broken the staging environment for three days. They ended the assignment on a Thursday and we had a replacement contractor starting Monday. That is the safety net. If that had been a direct hire, the manager would have been dealing with a PIP, an HR process, and a two-month backfill instead of a phone call.

Second reason: budget timing. Headcount approvals and project timelines rarely line up. A contract staffing arrangement lets you start the work now and formalize the headcount later. We see this constantly with Q4 projects that get funded in October but whose permanent headcount does not clear until January’s hiring plan.

The Fee Math, in Real Numbers

Nobody writes out the actual cost comparison, so here it is. Same person, same role, three different engagement models.

Take a real example. Your target hire would earn $110,000 a year on your payroll, roughly $53 an hour before benefits.

The numbers shift depending on markup, conversion credit, and benefits load. But the pattern holds. Contract is the most expensive per hour and the cheapest to exit. Direct hire is the most expensive upfront and the cheapest over two-plus years. Contract-to-hire usually wins on total cost if the conversion happens before month six.

One thing the math does not capture: the cost of a wrong hire. Ending a contract assignment is a phone call. Terminating a permanent employee is an HR event. If you are less than 80% sure about the permanence of the role or the candidate, contract-to-hire is the insurance policy. The premium is worth it.

Which One Fits Your Hire?

Forget the labels for a second. Answer four questions.

How soon do you need this person working? If the answer is “last week,” you need a staffing agency, because a direct hire search takes four to eight weeks and the person still has to give two weeks’ notice. A contract worker can often start within five to ten business days because there is no offer negotiation, no benefits enrollment, no background check backlog to clear.

Is this role permanent? If you know the role is funded for the long term and you have gone through the exercise of writing the job description, getting comp approved, and confirming headcount with finance, go direct. Pay the placement fee, skip the weekly margin, and bring the person into your culture from day one.

Are you sure about the candidate? Genuinely, though. Not “their resume looks great” sure. Actually sure. If you have any hesitation about fit, about whether the tech skills transfer from their last environment to yours, or about whether the role itself will survive the next reorg, contract-to-hire exists for exactly this scenario.

What is your budget structure? Contract spend often comes out of a different line item than permanent headcount. Some companies have frozen headcount but open project budgets. Some have the opposite. This is not a strategic question. It is an accounting question. But it determines which model is actually available to you right now, regardless of which one is theoretically optimal.

Most of the hiring managers who call us already know the answer to these four questions. They just have not connected the answer to the right engagement model yet. That is the conversation we have on the first call.

We do that math on the first call. Talk to our team if you want to run the numbers on a specific role. Fifteen minutes, no pitch deck.

How This Relates to Talent Acquisition

If you have read our piece on talent acquisition vs recruitment, you might wonder where staffing and recruiting agencies fit into that framework. Short version: talent acquisition is an internal strategy. Staffing and recruiting agencies are external services you plug into that strategy when your internal capacity hits a wall.

A company with a mature talent acquisition function might use a recruiting agency for the two or three searches per year that require deep passive sourcing their internal team cannot reach. A company without a TA function might use a staffing agency as their primary hiring channel for an entire department. Neither approach is wrong. The question is what your internal recruiting team can realistically handle on its own, given the number of open reqs, the difficulty of the roles, and whether the people you want to hire are actively looking or sitting comfortably at jobs they are not planning to leave.

Things Hiring Managers Ask Us

So is a staffing agency basically just a temp agency?

Historically, yes. Practically, not anymore. The “temp agency” label stuck from the 1980s and 1990s when most staffing firms placed clerical and light industrial workers for short assignments. The American Staffing Association now reports the industry places roughly 11 million workers annually across engineering, IT, healthcare, finance, and creative roles, with average assignment lengths stretching well past the “temp” label. A six-month infrastructure contract at $85/hour is not temp work. It is project-based employment managed by a staffing agency.

Do recruiting agencies only handle executive-level searches?

No. Some do. Those are executive search firms, specifically. A general recruiting agency handles placements across levels, from mid-career individual contributors through senior leadership. The fee percentage might shift, a junior marketing coordinator placement at $55K generates a smaller fee than a VP of Engineering placement at $220K, but the service model is the same: find the right person, present them, close the hire, collect the fee.

Realistically, what is the cost difference over a year?

Scroll up to the fee table. For a $110K role, the difference between a 12-month contract and a direct hire with a placement fee is functionally zero. The difference shows up on timelines shorter than a year, where contract is more expensive per month but cheaper to exit, and on timelines longer than 18 months, where direct hire pulls ahead because you stop paying a margin.

Can one agency do both?

Plenty do. KORE1 does. Most mid-size and large staffing firms offer contract, contract-to-hire, and direct hire placements. The firms that only do one or the other tend to be either very large commodity staffing houses focused on volume temporary placement or boutique retained search firms focused exclusively on executive roles. If your hiring needs span multiple models, which most companies’ do, look for a firm that operates across all three.

How fast can a staffing agency actually get someone started?

48 hours for roles where we already have screened candidates in the pipeline. Five to ten business days for specialized roles that require sourcing. The speed comes from the employment model. The worker is going on the agency’s payroll, not yours. No internal req approval, no benefits enrollment, no compensation committee review. You sign a service agreement, the agency sends a candidate, you interview, and the person starts. The operational overhead that slows down permanent hires does not apply.

Does it actually matter what I call it when I am shopping for a firm?

Not really. Call five firms with “staffing” in the name and five with “recruiting” in the name. Ask all ten to fill a permanent senior software engineer role. Nine will say yes. The market has converged. The distinction matters for understanding fee structures and employment models, which this article covers. It does not matter much for choosing which agency to call. Ask what engagement models they support, what industries they specialize in, and how they source. Those questions will tell you more than the label on their website.
