The short answer

If you want to know your payroll cost without a sales call, Gusto is easier to price. If you prefer ADP's HR support tiers or already use ADP for benefits or workers' comp insurance, get a quote and compare the total after any promotional period ends.

Law-firm checks

Payroll is not trust accounting; keep IOLTA in your practice management or accounting system.
If you pay remote staff abroad, compare contractor-payment fees and get local classification advice.
Confirm who files California state payroll taxes and unemployment insurance on each plan.
