Preferred Supplier List (PSL)

To replace a scatter of individual deals with one set of rules. Without a panel, different managers sign different terms, the same candidate arrives from three agencies in a week, and ownership arguments end with legal involved or somebody paying twice. A panel fixes commercial terms once, defines who owns an introduction and for how long, and puts data protection, vetting responsibilities and contract language on a common footing. It also reduces the relationships to a number the team can actually manage, so briefings stay consistent and feedback reaches someone who acts on it. Agencies often prefer the arrangement too, since membership means real access rather than speculative submissions, and they can plan resourcing around it inside their own recruitment agency software. The trade-off is narrower reach, which bites hardest in specialist markets.

Rarely to everyone at once, and the release model is a deliberate choice. Assigning a role to a single supplier draws the most committed effort but depends entirely on picking the right one. Tiered release goes to a first group and widens after a set period if nothing lands, balancing commitment against coverage. Simultaneous release across the whole panel maximizes volume and reliably produces duplicate submissions and rushed profiles. Whatever the model, three things belong in the brief: the submission deadline, the route submissions must travel, and how long an introduced candidate stays credited to the introducing agency. Submissions should arrive through the applicant tracking system or a supplier portal rather than manager inboxes, because a CV sitting in an inbox is invisible to the duplicate check and becomes the ownership dispute nobody can resolve.

The clauses that cause arguments later. Ownership rules and their duration decide who is credited when a person introduced months ago is finally hired. Replacement or rebate terms set what happens when a placed hire leaves early. Off-limits clauses stop a supplier approaching staff it placed with you. Data protection terms cover how candidate information was collected, what the candidate was told, and how long the agency may keep it. Vetting responsibilities allocate who performs right-to-work and background checks, and since those requirements differ by country and sometimes by sector, employers should confirm them with qualified legal counsel rather than assuming the agency has it covered. Service levels for response and submission times belong here too, along with the invoicing route and an escalation path for disputes.

Measure it and refresh it, or the panel becomes a habit. Useful measures are per-agency and comparable: how many submissions reached interview, how many interviews reached offer, acceptance rates, and how their hires performed once they joined. Briefing compliance deserves tracking too, because an agency that ignores the brief burns reviewer time regardless of eventual placements. Review on a fixed cycle rather than when somebody complains, tier the panel on evidence, and let membership genuinely change. Feedback has to travel both ways: agencies told why candidates were rejected recalibrate, while those left guessing send more of the same. Watching what panel activity does to your cost per hire alongside speed keeps the commercial case grounded in something measurable rather than in impressions.
