We're at 140 EE on a PEO, growing ~15% YoY. Health benefits are solid, payroll is fine, but the per-EE admin fee is starting to feel meaningful as a line item.
For people who've made the PEO → in-house transition: what was the trigger for you (headcount, cost, control, capability)? And what surprised you on the way out — exit fees, runoff on benefits, talent gaps when you suddenly own HR?
Disclosure: I'm an ADP District Manager. ADP runs both TotalSource (PEO) and Workforce Now (HRIS), so I see this transition from both sides — and I have a financial incentive in the answer. I'll be honest about both.
The math typically tips between 150-250 EE, but headcount is the wrong signal. The right signals are:
1. Per-EE PEO admin fee is now meaningfully above the cost of an internal HR hire. At 80 EE, a $90/EE/month PEO fee = $86K/year. That's less than one HR generalist. At 200 EE = $216K/year — that's an HR director plus a benefits coordinator. The math changes at scale.
2. You've outgrown the PEO's benefits flexibility. PEOs aggregate benefits across their master plan. Great when you're 30 EE and need group-buying leverage. Painful at 250+ EE when you want a custom plan design, a specific carrier, or non-standard ancillary lines. If your finance team is fighting the PEO's plan options, you've outgrown the model.
3. HR has become a competitive differentiator. Tech companies competing for talent often need an HRIS with a configurable career site, structured interview scorecards, OKR integration. PEOs don't optimize for that — they optimize for compliance + payroll baseline.
What surprised people who've made the transition (in my conversations):
- Exit costs are real but negotiable. PEOs typically have a clean exit at the natural renewal anniversary (reserves return, runoff is just IBNR). The expensive exit is mid-cycle. If you're considering a move, time it to your renewal — that alone saves $20-100K depending on size.
- You're now the employer of record. That means EPLI risk, workers' comp MOD-rate exposure, state unemployment registrations, FUTA/SUTA filings — everything the PEO absorbed. Most CFOs don't realize how much risk the PEO was carrying until they have to insure against it themselves.
- The HR talent gap. PEOs provide an outsourced HR helpdesk. When you leave, employees still need answers about leave, COBRA, FMLA, harassment investigations. You either hire that competency in-house or you contract it. Budget 0.5-1 FTE more than you think.
What tends to go well:
- Control over plan design. Most companies underestimate how much this matters until they have it.
- Faster decision cycles. No more waiting for the PEO to approve a new state hire or a contractor conversion.
- Better integration with finance. PEO data feeds are usually limited; native HRIS data integrates more cleanly with your GL.
For someone at 140 EE specifically: I'd watch the next renewal. If your PEO renewal is more than 90 days out, you have time to model the in-house TCO honestly. If it's within 60 days, you're past the clean-exit window for THIS cycle — start planning for the renewal AFTER this one.
Not every company should leave a PEO. Plenty of 300-EE companies stay in TotalSource because their HR ops team is small and they value the outsourced helpdesk. There's no single right answer.
