About each tool

ADP RUN

ADP RUN is the small business arm of ADP, the world's largest payroll provider. It delivers rock-solid payroll processing with automatic tax calculations, filings, and payments across all 50 states. ADP's massive scale means unmatched compliance expertise — they process payroll for 1 in 6 US workers. RUN includes HR tools, new hire reporting, and integrations with popular accounting software. The downside is pricing opacity — ADP doesn't publish rates, and costs can escalate with add-ons. The interface is functional but not as modern as Gusto or Rippling. Best for businesses that prioritize reliability and compliance over slick UX.

Gusto

Gusto is the go-to payroll platform for small businesses, combining full-service payroll with benefits administration, HR tools, and time tracking. It handles federal, state, and local tax filings automatically, offers direct deposit, and includes an employee self-service portal. Where Gusto excels is its user experience — it's genuinely easy to set up and run payroll in minutes. The platform also includes health insurance brokerage, 401(k) management, and workers' comp, making it a true all-in-one HR suite for companies with 1-100 employees. Compared to ADP or Paychex, Gusto wins on simplicity and pricing transparency. The trade-off is that larger companies (100+ employees) may outgrow its reporting and customization capabilities.
