HR & Recruiting

Gusto alternatives

Stay with Gusto if you are a small US business that wants simple payroll and benefits with public prices. Pick OnPay to save money, Rippling to run HR, IT and payroll in one system, or Deel to pay people abroad.

Rippling alternatives

Stay with Rippling if you'll use its IT and spend modules alongside payroll and HR. For payroll and basic HR at a published price, OnPay (or Gusto Simple, for one state) costs $169 a month for 20 employees.
