What to check before choosing

Whichever provider you shortlist, confirm these items in writing:

• Payroll taxes: Federal, state, and local tax calculations, filings, and payments.
• Benefits administration: Health, dental, vision, retirement plans, enrollment, and payroll deductions.
• Basic HR compliance: New-hire reporting, employee documentation, paid leave and overtime rules, and required notices.
• Workers' compensation: Whether coverage is included, integrated, or separately priced.
• Total cost: Monthly base fee, per-employee charges, benefits administration fees, and implementation costs.

If your business operates in California, pay particular attention to state-specific payroll taxes, paid sick leave, overtime, and other applicable employment requirements. Payroll software can automate many tasks, but it does not guarantee compliance with every obligation.fitsmallbusiness.com+5

My recommendation

For most small businesses, I'd shortlist Gusto and OnPay first, then compare Rippling if you need more sophisticated automation or ADP RUN and Paychex Flex if access to broader HR services matters more.

One question that would help narrow this down: How many employees do you have, and which benefits do you want to administer? For example, health insurance and a 401(k), or just retirement and basic payroll compliance.
