4 reasons payroll-bundled ATS modules frustrate US recruiting teams
Payroll companies are world-class at multi-state tax withholding, W-2 filings, Garnishments, and ACA compliance. Recruiting is a completely different discipline—it is a top-of-funnel marketing, speed, and structured evaluation workflow. When recruiting is treated as a minor checkbox inside a payroll suite, four bottlenecks appear immediately:
- High candidate drop-off on mobile and desktop: Many payroll-hosted career portals still force candidates to create an account with password rules or manually re-type work history that is already on their PDF resume. High-demand US engineering, healthcare, and skilled-trades candidates simply close the tab.
- Zero explainable AI ranking for 300+ applicant floods: When an Easy Apply role on Indeed or LinkedIn brings in 400 resumes over a weekend, payroll ATS modules leave recruiters clicking through PDFs one by one. Treegarden's Edera AI scores and ranks every applicant against your role-specific criteria and screening questions immediately.
- Hiring managers refuse to log into the payroll portal to score interviews: Department heads associate ADP, Paycor, and UKG with approving timesheets and PTO—not collaborative hiring. In Treegarden, Reviewer Mode gives hiring managers a dedicated, distraction-free candidate review and scorecard interface.
- Rigid pipeline configuration: Changing screening questions, adding a panel rubric, or automating a stage-trigger email in an HCM suite often requires global admin permissions or a support ticket.
The PEPM cost illusion: why your "bundled" ATS isn't actually cheaper
Finance teams often assume the recruiting module inside ADP, Paycor, or UKG costs "almost nothing" because it is quoted as $2.50 to $4.50 per employee per month (PEPM). Run the math at 150 to 250 employees:
- At 150 employees, a $3.50 PEPM recruiting module add-on costs $525/month ($6,300/year).
- At 250 employees, that same $3.50 PEPM add-on costs $875/month ($10,500/year)—even if you only have 12 jobs open!
- By contrast, Treegarden Growth is a flat $399/month billed annually ($4,788/year) for up to 25 active jobs and unlimited users, regardless of whether you have 100, 250, or 500 employees on payroll.

Frequently asked questions
Can we use Treegarden for recruiting while keeping ADP, Paycor, or UKG for payroll?
Yes. Most US companies using Treegarden keep their existing payroll provider (ADP Workforce Now, Paycor, UKG, Paylocity, or Gusto) for payroll tax filing and benefits deductions, while replacing the clunky payroll recruiting module with Treegarden.
Is a dedicated ATS more expensive than a payroll PEPM recruiting add-on?
For companies with 100+ employees, a dedicated flat-rate ATS like Treegarden ($399/month billed annually on Growth) is frequently cheaper than paying $3 to $5 per employee per month (PEPM) for a payroll-bundled recruiting module ($6,000 to $12,000/year at 150–250 employees).
