Understanding Pricing Models
How each model is typically priced and what affects your cost
PEO Pricing
PEO pricing is typically structured as a percentage of payroll (3-15%) or per-employee-per-month fee ($150-$250+). This includes HR administration, benefits access, workers' comp, compliance monitoring, and dedicated support. Your actual cost depends on headcount, industry risk classification, and benefits selection. Many California businesses find PEO total cost competitive when factoring in benefits savings and reduced liability.
ASO Pricing
ASO pricing is usually a flat per-employee-per-month fee ranging from $50-$150 depending on services included. This covers HR administration, payroll processing, compliance monitoring, and access to your HR Business Partner. You maintain your own benefits and workers' comp policies, so your total cost is the ASO fee plus your existing insurance costs. ASO often has the lowest upfront cost.
HRO / Consulting Pricing
HRO/HR consulting is typically structured as a monthly retainer based on hours and expertise level needed. Strategic HR consulting might range from $2,000-$10,000+ per month depending on scope. This works well for businesses with some HR capacity who need expert guidance on complex California employment issues, executive coaching, or interim leadership.
