All evaluations are based on publicly available information. We do not perform hands-on product testing.

Choose Gusto if

• You want transparent pricing without a sales conversation
• You have a relatively simple payroll setup in one or two states
• You want to get set up quickly without a heavy implementation process

Choose ADP RUN if

• You have employees in multiple states and need strong compliance support
• Your business has a complex workforce setup that warrants a full-service provider
• You prefer a dedicated account representative over a self-service model

The bottom line

For straightforward small business payroll, Gusto is the simpler, more transparent, and typically less expensive option. ADP RUN earns its place for businesses with genuine multi-state complexity or compliance requirements that justify the heavier setup and quote-based pricing.
