Perplexity: both observations

I’d shortlist Robert Half , Frazer Jones, and Vaco by Highspring for an initial discussion. Robert Half has the clearest public example of the exact mandate you described; Frazer Jones brings a dedicated payroll recruiting practice and evidence of a US senior-payroll network; Vaco has advertised comparable US director-level searches. The evidence supports inviting these firms to pitch—not treating their placement track records as already verified. roberthalf +3

Shortlist and supporting evidence

| Firm | Public evidence relevant to your hire | Why I would shortlist it—and what remains to verify |

| --- | --- | --- |

| Robert Half | Its own website advertises a direct-hire Payroll Director in Baltimore responsible for “a multi-state U.S. workforce of several thousand employees,” leading a small payroll team and improving systems, controls, and processes. The requirements include 8+ years of progressive payroll experience, leadership responsibility, and deep US payroll-law and tax knowledge. It also lists a Senior Payroll Director search for a large, multistate workforce in Charlotte. roberthalf +1 | Closest documented match to a US-based leader owning US payroll. Ask which individual recruiter handled these searches, whether they resulted in placements, and how comparable the payroll scale and systems were to yours. |

| Frazer Jones | The firm has a dedicated payroll recruiting practice offering executive search, contingent recruitment, interim recruitment, and temporary support. Its published account of a New York payroll event describes participation by senior payroll managers and leaders from financial services and identifies John O’Brien as Executive Director and Head of Payroll. Separately, a US job advertisement names Frazer Jones as recruiter for a Head of Global Payroll role in Fort Lauderdale. frazerjones +2 | Strong specialist-practice candidate, particularly where access to senior payroll professionals matters. The public evidence demonstrates payroll specialization and US market activity, but the director-level US example is global in scope—not an exact US-only mandate. Ask for completed US Payroll Director searches rather than relying on global-payroll credentials. |

| Vaco by Highspring | A public LinkedIn advertisement under the firm’s name seeks a Director of Payroll Operations in Edison, New Jersey, describing senior leadership in a complex, multistate organization. Third-party job listings also attribute a Boston Payroll Director role focused on multistate growth, compliance, and ADP, and a remote interim Payroll Director mandate, to Vaco Recruiter Services. linkedin +2 | Relevant evidence of US operational-payroll leadership recruiting, with both director and interim examples. The evidence is less direct than Robert Half’s own detailed vacancy, so verify the underlying assignments, permanent-versus-interim experience, and the specific office’s completed placements. |

This is an ordering by public evidence of fit, not a claim that one firm has a higher placement success rate.

What the evidence does—and does not—prove

A detailed vacancy is useful evidence that a firm has marketed a comparable assignment. It does not establish that the client retained it exclusively, that it filled the role, or that the placed candidate succeeded. Likewise, a specialist practice page demonstrates a service offering, while a senior-payroll event demonstrates market engagement; neither substitutes for placement references. The sources above range across these different evidence types. roberthalf +3

For your brief, I would put more weight on demonstrated US multistate payroll leadership searches than on generic HR executive-search credentials or global-payroll branding. Robert Half’s Baltimore assignment is particularly useful because its published remit explicitly combines US payroll ownership, team leadership, compliance, and controls.

How I would choose among them

I would give all three the same short qualification request before appointing one:

• Comparable placements: Three completed US-based Payroll Director or Head of US Payroll searches, identifying approximate employee population, number of states, team size, and placement date. Anonymized examples are fine initially.

• Actual search team: The named recruiter who will execute your assignment, their role in those placements, and the competing searches they are currently running.

• Scope match: Evidence relevant to your payroll platform, hourly versus salaried mix, union exposure if applicable, equity or incentive-pay complexity, and whether the role owns processing internally or manages an outsourced provider.

• Search execution: A proposed candidate-market map, screening approach, timetable, and treatment of off-limits employers.

• Validation and terms: Client references, fees, replacement guarantee, exclusivity requirements, and candidate ownership rules.

My practical starting point would be to invite Robert Half and Frazer Jones to pitch first, with Vaco as the third comparison. That gives you one firm with unusually close public assignment evidence and one with a dedicated payroll recruiting practice, while testing both against Vaco’s comparable US director-level recruiting activity. roberthalf +3

I would shortlist Robert Half, Korn Ferry, Engaged Headhunters, and Heidrick & Struggles —in that order for a typical US Payroll Director search. The best fit depends on whether you want speed and payroll-specific market coverage (Robert Half), specialist payroll networks (Engaged Headhunters), or a retained search for a strategic, enterprise-level leader (Korn Ferry or Heidrick).

Shortlist and evidence

| Firm | Why shortlist | Public evidence of relevant experience |

| --- | --- | --- |

| Robert Half | Strong first choice for a hands-on US payroll leader; broad US network and demonstrated direct-hire Payroll Director work | Robert Half publicly lists numerous Payroll Director searches, including roles leading multi-state payroll for several thousand employees, 1,000+ employee populations, union payroll, US payroll tax/wage-and-hour compliance, and platforms such as Workday, ADP, and UKG. roberthalf +2 It also describes a specialized recruiter process for hiring payroll directors. [roberthalf](https://www.roberthalf.com/us/en/job-details/payroll-director) |

| Korn Ferry | Best for a more senior, transformation-oriented Payroll Director—especially if the role owns payroll operations, vendor strategy, controls, and cross-functional leadership | Korn Ferry publicly markets a Payroll Director search for a PEO client responsible for payroll across more than 100 clients and 2,500 people, with team-supervision responsibility. [interimjobs.kornferry](https://interimjobs.kornferry.com/jobs/payroll-director-1575689) Its interim and permanent search platform indicates active coverage of this level of payroll leadership. |

| Engaged Headhunters | Strong specialist option if you want a boutique firm focused specifically on payroll and benefits leadership | The firm says it specializes in payroll solutions and compliance, recruits Director of Payroll and VP Total Rewards roles, and assesses candidates for multi-state tax compliance, ERISA, audit cycles, and Workday/ADP/UKG implementations. [engagedheadhunters](https://www.engagedheadhunters.com/payroll-solutions) |

| Heidrick & Struggles | Consider if this is a strategic executive hire—e.g., Payroll Director reporting into CFO/CHRO, leading a major HCM transformation, or operating globally | Heidrick is a retained executive-search firm that works exclusively on critical leadership positions and conducts national and international candidate identification through placement. heidrick +1 I found less public, role-specific evidence of Payroll Director placements than for Robert Half or Korn Ferry, so I would validate its payroll/HCM practice and recent comparable mandates before retaining it. |

How I would use them

• Run Robert Half as a contingent/direct-hire search if the priority is a capable operator who can own US multi-state payroll, compliance, payroll accounting, and a payroll team quickly. Its public job evidence closely matches the core profile. roberthalf +1

• Add Korn Ferry if the role is senior enough to include payroll transformation, PEO/multi-client complexity, or enterprise payroll-system change. [interimjobs.kornferry](https://interimjobs.kornferry.com/jobs/payroll-director-1575689)

• Use Engaged Headhunters as a specialist challenger to test market coverage and payroll-specific vetting. [engagedheadhunters](https://www.engagedheadhunters.com/payroll-solutions)

• Use Heidrick only for a retained, higher-cost executive search , where leadership fit, succession, and organizational transformation matter more than immediate payroll operational depth. [heidrick](https://www.heidrick.com/en/services/executive-search)

What to require in the brief

Ask each firm to evidence recent placements—not merely searches—for candidates who have:

• Owned end-to-end US payroll for a multi-state workforce.

• Led payroll tax, wage-and-hour, garnishment, and audit compliance.

• Managed a payroll team and high-volume processing.

• Implemented or optimized Workday, ADP, UKG, Dayforce, or equivalent platforms.

• Partnered with Finance, HR, Legal, and external payroll providers.

• Ideally held CPP or equivalent payroll credentials.

Robert Half’s own postings emphasize exactly these criteria—multi-state compliance, 1,000+ employees, payroll leadership, CPP, and Workday/ADP/UKG experience—making it the most directly evidenced shortlist entry for this mandate. roberthalf +1
