Most direct sourcing content assumes there is one way to do it: the organisation builds its own branded talent pool, connects it to a Vendor Management System or a Direct Hire platform, and manages it internally. There is a second model that gets far less attention and, for most organisations past a certain scale, performs better. A workforce partner, often the incumbent MSP or RPO provider, builds and runs the direct sourcing pool on the client’s behalf, at a margin well below standard agency rates, and is contractually measured against the same fill-rate and time-to-fill SLAs that govern the rest of the contingent programme.
The cost difference between the two models is smaller than either side likes to claim. The more important difference is who has a commercial reason to keep the community warm once the initial build is finished.
Why the margin still exists
A partner-delivered direct sourcing model does not eliminate cost the way pure self-sourcing does on paper. The partner still charges a fee for managing the pool, recruiting into it, and running the compliance work behind every placement. What changes is the size of that fee relative to a standard agency placement. Because the model draws on the client’s own brand and existing candidate relationships rather than the partner’s open market network, the partner is not paying to source each candidate from scratch, and the margin reflects that. It typically sits well under half of standard agency markup, without falling to zero.
That distinction matters commercially. A client comparing “free” in-house direct sourcing against a partner fee is not comparing like for like. The in-house version has a real cost too, it is simply an internal cost that rarely gets attributed accurately to the programme, salary time spent on engagement, content, and redeployment work that would otherwise sit somewhere else in the HR function. A partner-delivered model puts a visible price on work that an in-house model hides inside existing headcount.
The incentive problem nobody prices in
Staffing Industry Analysts has tracked direct sourcing participation at a fairly flat 30 to 36 per cent since 2016, despite a demonstrably strong cost case for close to a decade. That gap between the economics and the adoption rate is the real story, and SIA’s own research points to why: organisations struggle to get staffing suppliers, MSPs, platforms and internal hiring teams aligned around the same objectives, and internal direct sourcing programmes in particular tend to lose momentum once the initial build is complete.
The reason is straightforward. An internal team building a direct sourcing pool is rarely held to the same SLA discipline as the rest of the contingent programme. Nobody loses a contract if the pool goes quiet for six months. Engagement work competes for time against every other HR priority, and because the pool’s decline is gradual rather than a single visible failure, it rarely triggers the kind of intervention a missed fill-rate SLA would trigger elsewhere in the programme.
A partner running the same pool under contract does not have that luxury. If the community is not generating candidates fast enough to hit agreed fill-rate targets, that shows up in the same SLA reporting the rest of the programme is measured against, and the partner has a commercial reason, not just a professional one, to keep the pool engaged, growing and responsive. The incentive to do the unglamorous ongoing work, the engagement cadence, the redeployment offers, the content that gives candidates a reason to stay responsive, is structurally stronger when a contract depends on it than when it depends on one internal team’s discipline surviving competing priorities indefinitely.
The benefits of each model
An organisation building direct sourcing for the first time, at modest volume, with a small enough contingent population that one person can plausibly own engagement personally, often does fine running it in-house. The stakes are low enough that inconsistent attention costs little, and the exercise itself builds internal capability worth having.
Once volume grows to the point an MSP is justified, the calculation changes. The pool now needs to hit fill-rate SLAs that matter commercially, alongside supplier channels that are already contractually accountable for their own performance. Running the direct sourcing channel to a lower standard of accountability than every other channel in the same programme is an odd inconsistency to build into a workforce strategy, and it is usually not a deliberate choice so much as something nobody examined closely once the initial platform was switched on.
The organisations most likely to be quietly underperforming on direct sourcing are not the ones without a programme. They are the ones with a programme nobody is actually accountable for.
Anne Rutledge, Executive Director of Talent Solutions, notes that when clients ask why their direct sourcing numbers have flattened after a strong first year, the answer is almost never the candidate pool itself. It is that the person originally responsible for keeping it warm moved on, took the informal knowledge of how the community was engaged with them, and nobody inherited the accountability along with the task.
