A 25-person US agency hires remote W-2 employees and contractors across 8 different states.

• Outcome with Gusto: The team signs up online, configures multi-state tax filing via Gusto Plus ($80 base + $12/employee), and sets up health insurance benefits. Direct deposit runs automatically. Total cost: ~$380/month.

• Outcome with ADP: ADP Workforce Now handles global payroll processing, local tax compliance in each country, union wage scales, and ACA compliance. Dedicated account teams oversee audit management.

• Modern Employee Experience: Businesses that prioritize an easy digital onboarding experience for employees and contractors.
• Integrated SMB Benefits: Seamless access to 401(k), health, vision, and dental plans tailored for small businesses.

When ADP is Still the Better Choice

ADP is the necessary choice for enterprise organizations, global companies, and businesses with complex payroll requirements.

How to Choose the Right Solution for Your Team

3. Evaluate HR Resource Availability: If you lack an in-house HR team, Gusto Premium provides dedicated certified HR advisors.
4. Test Employee Portal Experience: Review both mobile apps to evaluate how easily employees can access tax forms and pay stubs.
