// An underwriter's notes on PEO
I'm Victor Difusco, an underwriter at Cornerstone PEO. Every week I read dozens of submissions from brokers around the country — what gets approved, what gets declined, and what you're overpaying for. I don't sell. I underwrite. And I can help.

No brochure language. A PEO — Professional Employer Organization — becomes your co-employer for admin purposes. Logically, it breaks down like this:
That's the whole trade. You keep the steering wheel; the paperwork rides in the back.
Who this is for
Two people who just need payroll handled. Fifty people drowning in comp audits. Either way, there's a lane — from simple admin and payroll services all the way up to the full PEO stack. You don't need workers' comp for us to have the conversation.
02
Patterns I see across dozens of submissions a week. This is the stuff that never makes it into the sales deck.
a.
First quotes are estimates. The approved rate comes after I read the submission — loss history, class mix, payroll verification. When the final number moves, it isn't a bait-and-switch. It's underwriting doing its job. Ask what could move your quote before you sign, not after.
b.
Wrong class codes. Payroll never split between office and field. Stale loss data feeding the formula. Your experience mod is the most expensive number you never check — and it follows you from carrier to carrier until someone fixes the inputs.
c.
Traditional comp bills you on estimated payroll, then audits you a year later and sends the difference as a bill. Pay-as-you-go ties premium to each actual payroll run. No estimates, no year-end shock. If your broker never offered it, ask why.
d.
Severe loss history with no corrective story. A class mix that doesn't match the payroll. Sloppy reporting that makes me guess. Underwriters don't decline businesses — we decline uncertainty. A clean, honest submission beats a polished one every time.
03
Nobody should hand over payroll, comp, benefits, and HR compliance to a stranger in one leap. So don't.
1
Hand off the admin grind. Keep everything else exactly where it is.
2
Ninety days. Watch how we perform when something goes wrong — that's the only review that matters.
3
Add workers' comp, benefits, and the compliance stack once the relationship proves itself.
04
The three things I check on every submission — and what they mean for your premium.
Your experience modification factor compares your loss history to your industry average. 1.00 is par. Above it, you pay a surcharge on every premium dollar; below it, a credit.
It follows you between carriers. And it's built from inputs — class codes, payroll splits, loss data — that are wrong more often than anyone admits. When I reprice a submission, this is the first page I open.
Your loss runs are the claim history your insurer reports about you — the raw material your mod is built from. Duplicate claims, reserves never adjusted down, claims that should be closed: I see it weekly.
They're yours by right. Your current agent can pull them in minutes. Most owners have never actually read theirs.
Every job in your company maps to a classification code, each with its own rate. Office staff coded as field labor is one of the most common — and most expensive — errors in the stack. Ten minutes to check; five figures to fix.
05
Most of my work starts with someone else spotting the problem first — a broker, a CPA, an agent. If that's you, here's how this works.
For brokers & agents
I read your submissions. Here's what makes one sail through my desk:
My commitments: your client stays your client — I don't poach books, ever. You're looped in on everything. If a PEO isn't the answer, I say so and send them back to you.
The partnership part: this is a real strategic partnership, not a favor. When someone you send my way becomes a Cornerstone client, you share in the economics. Both directions.
For accountants & CPAs
You keep the client — that never changes, and a clean back office makes you look good. Same as the brokers: a strategic partnership that runs both ways, including when your referrals come aboard.

I'm an underwriter at Cornerstone PEO, a family-owned PEO out of Medford, New Jersey. My desk is where broker submissions from around the country land — workers' comp, payroll, benefits, the full picture.
I don't sell PEO. I decide who gets in, at what rate, and why. That vantage point is the whole point of this site: the view from inside underwriting, written so a business owner can actually use it.
And I'm local. I live in Putnam / Westchester County, NY — if you're in the area, I'll come to you.
