A contractor you bring in for a stretch of work turns out to be one of the people you most want to keep. They pick up how the team works without much hand-holding, they deliver, and they earn real trust. Then the assignment ends, they move on, and the working relationship goes with them.
Months later, a similar role opens, and the search begins again from nothing: a new brief to an agency, a new round of screening, a new set of candidates who aren't the person you already knew could do the job. For anyone who runs contingent hiring at scale, none of this reads as unfamiliar. What's easy to miss is the pattern underneath: the same thing, repeating.
Why do mature contingent programs keep losing their best contractors?
The answer isn't that they're being managed badly. In the traditional model, the relationship with the talent never belonged to the organization in the first place; it belonged to the staffing agency. So when an assignment ends, the contractor returns to the agency's pool, not the company's, and the next time the need comes around, the search starts from nothing. The program isn't losing people it was holding; it's discovering it was never holding them at all.
And the pattern, proven people cycling out and roles starting fresh, isn't particular to one kind of company or one kind of role. It shows up across industries:
-
Life sciences companies hiring lab technicians for each new study;
-
Banks staffing risk analysts through a remediation program;
-
Utilities bringing in field engineers for one build, then the next;
-
Manufacturers filling the same specialized line roles season after season.
Whatever the work, an organization that hires contingent talent in volume has likely felt it: a proven specialist finishes, leaves, and the next time the need comes around, the program is starting over. That's not a sign the program is run badly; it's the ordinary way agency-led hiring works.
What does it cost to let a proven contractor walk away?
It costs more than it looks, because the price never lands in one place. Start with the agency's cut, and it isn't trivial. In US IT staffing, for example, the agency's gross margin, the portion that sits on top of what the worker is actually paid, has run between roughly 23 and 25 percent for over a decade, according to Staffing Industry Analysts. On a contractor you've already used, that's a quarter of the bill you're paying again to re-access someone you know. Familiar roles also sit open for weeks while a fresh search runs, even though the organization already knows what “good” looks like. And what the last contractor understood about how the work gets done here leaves with the assignment, to be rebuilt from scratch by whoever comes next.
There's a quieter cost, too. Every time a proven person is dropped at the end of an assignment and cold-rehired through the market later, the organization trains its best contingent talent to behave like one-offs, less likely to return, and less likely to refer the next strong candidate. The relationship that could have compounded gets reset to zero instead.
None of these costs arrives as a line item anyone would challenge. They're spread thin across requisitions: a margin here, a few extra weeks there, a little lost knowledge somewhere else. Totaled across a year of repeat roles, it's real money and real time; it just never shows up as one number in one place, so it rarely gets questioned the way a sum that size normally would.
Why doesn't a well-run program prevent this?
The natural reaction is to treat this as a discipline problem: tighten the process, lean harder on suppliers, and the leak closes. For many programs, it won't, and the reason matters. The gap isn't in how well the program is run; it's in what the program is built to do. A contingent program is designed to fill the role in front of it, quickly and compliantly, and then close the requisition. Keeping proven people connected once the assignment ends was never part of that design.
So a program can hit every service level it's measured on and still let its most valuable talent walk back into the open market every time, not because anyone is underperforming, but because the model was never built to hold onto them. There's no version of running that same model harder that hands the organization a relationship it set up to live somewhere else.
Won't my MSP or VMS already solve this?
Not on their own, because they're built for different jobs. An MSP manages suppliers and the program; a VMS gives visibility and control over requisitions, spend, and compliance. Both make the current model run better, and both are worth having. But neither is designed to own the relationship with the talent after an assignment ends; that proven contractor still returns to a supplier's pool rather than the organization's. So the same gap remains, even in a well-tooled, well-managed program: the system that runs the hiring isn't the system that keeps the people.
What would it take to keep proven talent connected?
The talent an organization has already vetted and watched succeed doesn't have to scatter back into the market the moment an assignment ends. There's an approach built on keeping those people connected and within reach for the next role, so redeploying someone already trusted becomes the normal path rather than paying an agency to rediscover them.
It has a name: direct sourcing. Reusing proven people is the entry point, but the same approach widens the pool over time, drawing in alumni, referrals, past applicants, and people who opt in because they want to work for the organization specifically. It's less a tool to install than a different answer to a question most programs have never put to themselves directly: who should own the relationship with the talent you keep coming back to?
The people you've already proven don't have to start as strangers every time. See how owning the relationship turns repeat hiring into a contingent workforce that compounds, getting faster and more cost-efficient the more you use it.

Frequently Asked Questions
What is direct sourcing?
Direct sourcing is when a company uses its own brand and a private pool of talent (former contractors, alumni, applicants it has already screened, and people who have opted in) to fill roles directly, usually on a contingent basis, rather than asking a staffing agency to find someone new each time. The talent community belongs to the organization, which engages and hires from it directly. It's increasingly treated as a core part of a modern contingent workforce strategy.
How is direct sourcing different from using a staffing agency?
With an agency, the agency owns the relationship with the talent and takes a markup on each placement. Direct sourcing keeps both the relationship and the talent pool with the enterprise, so proven people can be re-engaged directly and roles filled faster on repeat hires. For organizations focused on agency cost reduction, that retained relationship is where much of the saving comes from.
Does direct sourcing replace an MSP or staffing suppliers?
No. Direct sourcing is one channel within a broader contingent workforce strategy, not a substitute for suppliers. According to Staffing Industry Analysts, it's best framed as a complement that preserves the speed, scale, and market reach suppliers provide, while giving the organization a faster, lower-cost route for the repeatable roles where it already knows what good looks like.
What kinds of roles is direct sourcing best for?
It works best for recurring, repeatable roles where demand returns and proven talent already exists, the role families an organization staffs year after year. These are the roles where building talent communities and enabling contractor redeployment pay off most, and where workforce efficiency gains compound over time. It's less suited to genuinely one-off needs, where there's no pattern to own.
Is direct sourcing the same as the procurement term?
No. In procurement and supply chain, “direct sourcing” means buying goods or materials straight from a producer without an intermediary. In a workforce context, it refers to sourcing talent directly into a community the organization owns, rather than through staffing agencies.
