Frequently asked questions

What is a PEO and how does co-employment work?

A PEO (Professional Employer Organization) enters a co-employment arrangement with your company. The PEO becomes the employer of record for tax and insurance purposes, which lets your employees access Fortune 500-level benefits and the PEO's workers' comp rates. You keep day-to-day control of your employees.

Is Insperity or ADP TotalSource bigger?

ADP TotalSource is backed by ADP, one of the largest HR technology companies in the world. Insperity is a large standalone PEO with over 300,000 worksite employees across the US. Both are ESAC and IRS-certified.

Can a small company (under 25 employees) use either PEO?

Yes. Both providers work with companies as small as 5 employees, though pricing tends to favor larger headcounts. Under 15 employees, it's worth comparing a PEO to simply purchasing small-group health insurance directly.

How long does implementation take?

Both typically take 4–8 weeks to fully onboard, including benefits enrollment, payroll migration, and HR system setup. Plan for the onboarding period to require active HR bandwidth from your side.

TriNet organizes clients by industry vertical and tailors benefits, compliance, and consulting to sector-specific norms. Insperity is the white-glove service PEO. TriNet is the industry-specialist PEO. Both are IRS-certified. Both serve 50-500 employee companies. The difference is whether you want depth of service or depth of industry expertise. Not sure?

TriNet is the stronger PEO for companies in tech, professional services, and life sciences that want industry-specialised benefit packages and a PEO with deep vertical expertise. ADP TotalSource is the stronger call for companies that need ADP's compliance infrastructure, want to stay within the ADP ecosystem as they grow beyond PEO, and where the ADP brand carries weight with investors or the board. The deciding signals are industry vertical, growth trajectory, and exit strategy.
