Service model comparisons
Choose the relationship before the vendor.
Each comparison isolates the decision that changes cost, control, and administrative depth — so the vendor conversation happens second.
PEO vs. ASOChoose a PEO for a broader co-employment relationship; choose an ASO for outsourced administration without co-employment.Fractional vs. full-time HRFractional HR fits bounded senior leadership needs; a full-time hire fits sustained daily ownership across a broad workload.PEO vs. payroll servicePayroll software or a payroll bureau solves a narrower problem than a PEO; the comparison is about what else you have to own.Insperity vs. TriNetBoth are national PEOs serving the same general size range; the differences show up in service model, industry focus, and contract terms.PEO vs. HR consultantA PEO absorbs recurring administration and risk through co-employment; a consultant advises and implements while you stay the employer.PEO vs. benefits brokerA broker shops your benefits; a PEO moves you into its own co-employment group. They are different buying power, not a better or worse version of the same thing.
