What is a Professional Employer Organization (PEO)?

A Professional Employer Organization (PEO) is a company that enters into a co-employment relationship with your business, taking on responsibility for payroll processing, payroll tax compliance, HR administration, employee benefits, workers' compensation, and risk management. The PEO becomes the employer of record for tax purposes, while you retain full control over your employees' day-to-day work. PEOs like KeyHR allow small and mid-sized businesses to access Fortune 500-level HR services and benefits at a fraction of the cost of building an in-house HR department.

How is a PEO different from a payroll service?

A payroll service processes your payroll but leaves you as the employer of record with full compliance liability. A PEO like KeyHR becomes your co-employer — filing payroll taxes under our EIN and assuming legal responsibility for payroll tax compliance. PEOs also provide HR compliance, employee benefits, workers' compensation, and risk management services that payroll processors do not offer.

How much does a PEO cost?

PEO fees are typically structured as a percentage of total payroll (usually 2–12%) or a flat per-employee-per-month fee. NAPEO research shows that businesses using a PEO save an average of 27.2% on HR administration costs compared to managing these functions in-house, when accounting for the full cost of staff time, software, benefits purchasing, and compliance penalties avoided.

How long does it take to switch to a PEO?

Most businesses complete the transition to KeyHR within two to three weeks. Our onboarding team handles data migration, parallel payroll runs, employee portal setup, and benefits enrollment. We design the transition to be seamless — your employees typically notice only improvements, like access to the Enwage self-service portal and better benefits options.

Payroll vs. PEO: Which HR Outsourcing Option Is Right for You?

Quick Answer

Should your business choose a payroll service or a PEO for HR outsourcing?

The payroll vs PEO decision comes down to the scope of your HR needs. A payroll service is the right choice if you only need accurate tax filing and direct deposit. A PEO is the right choice if you also need group health insurance, workers compensation coverage, HR compliance support, or access to an HR team. For most Florida businesses with 5 to 150 employees, the PEO delivers more value: the savings on workers comp premiums and the avoided cost of compliance violations often exceed the PEO additional fee. The key question is not which costs less, it is which protects your business better.

When business owners decide to outsource HR functions, the first question is usually: "Should I use a payroll service or a PEO?" The answer depends on how much HR support your business actually needs — and understanding the difference between the two is the first step.

What Does a Payroll Service Do?

A payroll service processes your payroll. That's its core function. You provide the hours and compensation data; the payroll company calculates withholdings, generates paychecks or direct deposits, and files the associated payroll taxes. Some payroll services also offer basic HR tools like onboarding forms or employee self-service portals, but these are typically add-ons rather than core offerings.

Well-known payroll services include ADP Run, Gusto, Paychex, and QuickBooks Payroll. These are software-first platforms designed to automate payroll processing. They do not provide HR consulting, workers' compensation coverage, group health insurance, or compliance guidance.

What Does a PEO Do?

A Professional Employer Organization (PEO) enters into a co-employment relationship with your business. Under this arrangement, the PEO becomes the employer of record for tax and benefits purposes, while you retain full control over day-to-day operations, hiring decisions, and business direction.

This co-employment structure allows the PEO to pool your employees with thousands of others across its client base — giving your small business access to Fortune 500-level benefits, lower workers' compensation rates, and dedicated HR expertise that would be impossible to access independently.

Cost Comparison

Payroll services typically charge $40–$200/month plus $4–$12 per employee per month. For a 20-person company, expect to pay $120–$440/month.

PEOs typically charge 2–12% of total payroll or $100–$200 per employee per month. For the same 20-person company earning an average of $50,000/year, a PEO might cost $1,700–$3,300/month — but this includes workers' compensation coverage, group health insurance access, HR consulting, and compliance support that would otherwise cost significantly more to obtain separately.

NAPEO research shows that businesses using PEOs grow 7–9% faster and have 10–14% lower employee turnover than comparable businesses that don't use PEOs. The ROI calculation goes well beyond the direct cost comparison.

When to Use a Payroll Service

You have a simple, stable workforce with minimal HR complexity
You already have strong in-house HR capabilities
You have an existing workers' comp policy you're satisfied with
You offer competitive benefits independently
Your primary need is automating paycheck processing and tax filings

When to Use a PEO

You want access to better health insurance without the cost of a large employer
Your workers' comp rates are high or you've had claims issues
You're spending significant time on HR administration instead of your business
You're growing and need scalable HR infrastructure
You operate in a highly regulated industry (construction, healthcare, staffing)
You want dedicated HR expertise without hiring a full-time HR director
