How Do Optimum HR and CoAdvantage Compare on Price?
Optimum HR uses transparent, unbundled pricing ranging from $100 to $150 per employee per month, while CoAdvantage structures costs through custom quotes that commonly follow either a percentage of payroll model or a per employee per month model with separate line items. That difference means Optimum HR clients can clearly see what each service costs, while CoAdvantage proposals require a consultation and a detailed quote to compare equivalent service levels. Both providers tailor pricing to employee count, payroll volume, benefits participation, and service requirements.
What Does Optimum HR Cost?
Optimum HR prices its services on a per employee per month (PEPM) basis, ranging from $100 to $150 PEPM, which provides more predictable costs than percentage of payroll models where fees rise automatically as payroll grows. Pricing varies based on employee count, benefits needs, workers compensation exposure, and service scope, and the unbundled structure means businesses can see exactly what each service contributes to their PEO investment. This gives clients clearer pricing visibility than bundled packages where individual service costs fold into a single fee.
What Does CoAdvantage Cost?
CoAdvantage does not publish public pricing and generates a custom quote after a consultation that reviews employee count, payroll volume, benefits selections, and workers compensation exposure. CoAdvantage is commonly structured either as a percentage of payroll or as a per employee per month model with separate line items for workers compensation, benefits administration, and administrative fees, and independent estimates place common costs near $20 to $30 per employee per week. Businesses should also account for possible implementation and technology fees that may apply at setup.
