    QUICK ANSWER

    IT hiring agencies source, screen, and place technology workers, from help desk to senior engineers, either as permanent hires or contractors. They come in a few flavors: contract staffing, direct-hire recruiting, managed services, recruitment process outsourcing, and offshore staffing partners. An agency is worth it for a one-off or short-term role. For a team you’ll need for years, a model that recruits and keeps the person beats paying to fill the same seat over and over.

    A few jobs ago I had an IT role sit open for weeks. Every week it stayed empty, something on the roadmap slipped, and I got more willing to pay almost anyone to make the problem go away.

    That feeling is the entire business model of IT hiring agencies. They sell relief from an open seat.

    There’s nothing wrong with that. I’ve used them, and I run a staffing company now at Full Scale, so I’ll defend the good ones. But “agency” covers a half-dozen very different things, and most buyers shortlist two or three of them and never hear about the rest. Here’s how the category actually breaks down, and how to tell which one fits what you need.

    What IT hiring agencies actually do

    An IT hiring agency is a company you pay to find and place technology workers. The roles run the whole range: support and help desk, system and network admins, security, data, QA, and software engineers. Some place permanent employees, some rent you contractors, some run your whole hiring function.

    The label hides the differences. These five models all call themselves IT hiring agencies, and they behave nothing alike.

    TypeWhat they sellHow you payFits
    Contract staffingContractors who stay on the agency’s payrollHourly markup, every invoiceShort projects, surge capacity
    Direct-hire recruitingA permanent employee for your payrollOne-time placement fee on hireFilling a single open role
    Managed servicesAn outcome they run for you (e.g. a help desk)Monthly service contractSteady-state functions you’d rather not run
    Recruitment process outsourcingThey run part of your hiring functionRetainer or per-hireHigh-volume hiring at scale
    Offshore staffing partnerA dedicated remote employee who works for youFlat hourly rate, no placement feeOngoing engineering and product work

    If you only knew about the first two, you’re in good company. Most IT hiring shortlists are a contract shop and a direct-hire recruiter. The last three change the math in ways that matter for engineering teams especially.

    The cost model, briefly

    I won’t rehearse the whole fee breakdown here, because I covered it in detail for engineering roles in this piece on the software developer recruitment agency model. The short version: a direct-hire placement runs roughly 20 to 25 percent of first-year salary, more for senior roles, and contract staffing adds a markup that recurs on every invoice. The HR reference site Eddy puts permanent fees in the 15 to 25 percent range as a floor.

    Where it gets genuinely ugly is contingency search for hard-to-fill technical leadership, where I’ve seen fees climb toward half a year of salary. IT recruiters charging up to six months of salary is a real thing, not a horror story.

    The fee isn’t the part that should worry you, though. It’s what the fee is buying.

    Every placement model shares the same gap

    Here’s the thing that took me a few expensive hires to internalize.

    An IT hiring agency fills a seat. It does not build you a capability.

    The contract shop, the direct-hire recruiter, the high-volume RPO, they all get paid at the moment of placement. Their product ends the day the person starts. Whether that hire ramps up, fits the team, or is still there in a year is your problem, not theirs.

    For a lot of IT work, that’s fine. If you need a contractor to handle a migration over the summer, placement-and-done is exactly the right shape, and you don’t want a long relationship anyway.

    It’s the wrong shape for the work you’ll need forever.

    Your engineering team is not a seat to fill once. It’s a capability you’re going to keep staffing, growing, and retaining for as long as the company builds software. Paying a finder’s fee per head for something permanent is the most expensive way to do it, and it leaves you owning the hardest part, keeping good people, completely alone.

    Building a development team?

    See how Full Scale can help you hire senior engineers in days, not months.

    Demand makes this worse. ManpowerGroup found that roughly three out of four employers worldwide can’t find the skilled people they need, and technology is at the sharp end of that shortage. When good engineers are this hard to find, losing one you already have hurts twice: the gap, and the fee to fill it again.

    When an IT hiring agency is the right call

    I’m genuinely not anti-agency. A few situations where one is the right tool:

    • A short-term or project role. Contract staffing exists for exactly this. You need hands for three months, you don’t want headcount, an agency contractor is clean.
    • A single permanent hire you can fully onboard yourself. If you have one open seat and the in-house leadership to absorb a new person, a direct-hire recruiter doing the sourcing can earn the fee.
    • A steady-state function you don’t want to run. A managed help desk or a monitored service is a reasonable thing to hand to a managed services provider. We’ve written before about where managed services beat staff augmentation and where they don’t.
    • A leadership search you’ll do once. A retained search for a head of IT or VP of Engineering, someone you expect to keep for years, is worth paying to get right.

    The honest test is the same one I apply to every hire: how long do I need this person, and who owns whether they stay.

    The category most shortlists miss

    There’s a sixth model that rarely makes the IT hiring shortlist, and it’s the one I bet my company on.

    An offshore staff augmentation partner is an IT hiring agency in the sense that we recruit and place technology talent. But we don’t get paid to fill a seat and leave. We recruit the developer, employ them, handle payroll and benefits and HR, and keep them on your team for the long haul. The developer works directly for you, and we own keeping them there.

    That last part is the whole difference. The incentives line up. We only keep getting paid if your developer stays productive on your team, so keeping good people happy is now our job, not just yours.

    The results show up in the numbers. Our developer retention runs 93 percent, and we’re Great Place to Work Certified in the Philippines, where 95 percent of our team calls it a great place to work versus 65 percent at a typical local company. A senior engineer runs about $35 an hour, fully loaded, with no placement fee bolted on top. And the Philippines happens to be the third-largest English-speaking country in the world, which is a bigger deal for a remote team than most people expect.

    When SOTA Cloud, a dental imaging software company, couldn’t fill its engineering roles locally, its CTO didn’t want a stack of resumes. He wanted a team that would stick. You can read how SOTA Cloud scaled with pre-vetted engineers for the full story. The model we used there is the same one I’d point any engineering leader toward for ongoing work.

    The mistake I’d warn you off, whichever direction you go:

    Don’t pick on price alone. Chasing the cheapest option you can find, what I call cheapshoring, is how teams end up paying twice. Our engineers are trained on the Product Driven approach because cheap labor that can’t think through a problem costs more than it saves.

    How to evaluate any IT hiring agency

    Whatever type you’re considering, put these questions on the table before you sign:

    • How long do you actually need this role filled? A few months points to contract staffing. Years points to a partner who owns retention, not a per-hire fee.
    • Who’s responsible if the person leaves? With most agencies, you re-hire and re-pay. With a staffing partner, they replace the person. Get it in writing.
    • How do they find candidates? Real recruiting reaches people who aren’t applying anywhere. “We post the role and screen applicants” is something you can do without paying agency rates.
    • What’s the two-year cost, not the two-month cost? Add the fee, the turnover risk, and the loaded cost of the hire. The cheap-looking option usually isn’t.
    • Do they care about the work or just the placement? The dedicated team model only works when the partner is invested in your product, not just billing the seat.

    The talent crunch isn’t getting easier, and I’ve written about why the usual fixes fall short in this piece on the developer shortage and what actually works. The right answer depends on the job in front of you. Just don’t let “we have a seat to fill” turn into “we’ll rent this seat forever.”

    Frequently asked questions

    What is an IT hiring agency?

    An IT hiring agency is a company that finds, screens, and places technology workers for other companies, covering roles from help desk and system administration to security, data, and software engineering. Depending on the type, it places permanent employees, supplies contractors, or runs part of your hiring function for you.

    What types of IT hiring agencies are there?

    The main types are contract staffing firms, direct-hire recruiters, managed services providers, recruitment process outsourcing firms, and offshore staffing partners. They differ in whether the worker is permanent or contract, who employs them, and whether the agency owns anything after the placement.

    How much do IT staffing agencies charge?

    Direct-hire placements typically cost 20 to 25 percent of first-year salary, with senior technical roles running higher, while contract staffing adds an hourly markup that recurs on every invoice. The full breakdown for engineering roles is in our guide to the software developer recruitment agency model.

    When should you not use an IT hiring agency?

    Skip the per-placement agency model when the role is permanent and ongoing, like your core engineering team. Paying a fee every time you fill or refill a long-term seat is more expensive than a staffing partner that recruits, employs, and retains the person for you.

    An open seat makes you want to pay anyone to fill it. The better question is whether you’re filling a seat or building a team. If it’s a team you need, let’s talk about how we’d build it.
