What does a PEO do?
Quick Answer
A PEO (Professional Employer Organization) becomes the co-employer of a business's workforce, handling payroll, benefits, HR, workers comp, and compliance under one contract while the owner keeps day-to-day control.
PEO is the acronym owners hear right after the back office starts breaking. Here is what the arrangement actually is, minus the sales gloss.
How does a PEO arrangement work?
The PEO becomes the co-employer: employer of record for payroll taxes, benefits, workers comp, and compliance, while the owner keeps complete operational control — who gets hired, who gets fired, who works Saturday. Employees get paychecks and benefits through the PEO’s scale; the owner gets one contract instead of five vendors.
When does a PEO make sense — and when is it too much?
PEOs shine for businesses that want big-company benefits pricing and full administrative offload, typically from around ten employees up. For smaller teams, or owners who mainly need the payroll pain gone, a payroll-and-HR service model is often the better-fitting tool — the distinction covered in When should a business outsource payroll?, and the broader staffing question in Does a small business need an HR department?.
Which model fits is exactly the kind of question ProtectHealth’s Paychex partnership was built for: Paychex operates across the payroll, HR-support, and PEO spectrum, so the conversation can land on the right-sized tool instead of the tool someone happened to be selling.

Frequently Asked Questions
What is co-employment in a PEO arrangement?
Co-employment means the PEO becomes the employer of record for payroll taxes, benefits, and certain compliance duties, while the business owner remains the worksite employer directing daily work, hiring, and firing.
How is a PEO different from a payroll service?
A payroll service processes pay and tax filings as a vendor. A PEO takes on co-employment, bundling payroll with benefits administration, workers comp, and HR compliance under its own employer identification.
Does a PEO decide who a business hires and fires?
No. Operational control — hiring, firing, scheduling, and management — stays with the business owner. The PEO handles the administrative employer duties.
What does a PEO typically cost?
PEOs typically charge a percentage of payroll or a flat per-employee monthly fee. Whether the cost pencils depends on headcount, benefits goals, and how much administrative burden the business is carrying.
