Frequently Asked Questions

How long does it take to set up a PEO?

Setting up a PEO typically takes 2–4 weeks from signing the agreement to running your first payroll. The timeline depends on the number of employees, the complexity of your benefits plan, and how quickly you can provide required documentation. Key HR can onboard straightforward cases (1–25 employees, no existing benefits) in as little as 7–10 business days.

What information do I need to set up a PEO?

To set up a PEO, you typically need: business formation documents (articles of incorporation or LLC agreement), Federal Employer Identification Number (FEIN), state employer tax registration numbers, current workers' comp policy information, employee roster with compensation and job classifications, and payroll history for the current year (for W-2 accuracy). Key HR's onboarding team guides you through every document requirement.

Can I set up a PEO quickly if I have an urgent workers' comp need?

Yes — Key HR can expedite workers' comp coverage for urgent situations. If your current workers' comp policy is being cancelled, if you're starting a new business and need coverage immediately, or if you've had a claim and need to find new coverage, Key HR can often provide interim coverage within 24–48 hours while the full PEO onboarding is completed.

What happens during PEO onboarding?

During PEO onboarding, your dedicated Key HR account manager: (1) Collects your business and employee documentation; (2) Sets up your payroll configuration in the Enwage platform; (3) Establishes your workers' comp coverage and classification codes; (4) Coordinates employee benefits enrollment if applicable; (5) Trains your HR contact on using the Enwage platform; (6) Runs a test payroll before going live. Most clients describe the process as straightforward with Key HR's guided onboarding.

Do my employees need to do anything when I set up a PEO?

Yes — employees need to complete a brief onboarding process with the new PEO. This includes: signing updated employment paperwork acknowledging the co-employment relationship, completing new I-9 verification (if not already on file), enrolling in benefits plans (if applicable), and setting up their employee self-service account in the Enwage platform. Key HR provides employees with a simple onboarding portal in both English and Spanish to complete this process.
