My brother had an issue with Gusto, but I've not yet, after having used them for... probably at least 10 years now. Maybe longer. I was a refuge from quickbooks payroll which managed to screw up state filings such that I had 2 years of bad filings with the state where they were charging me late fees for things QP screwed up. Huge hassle, cost me days of time and a drive to the state capital to turn in paperwork in person. I swore off quickbooks payroll and have been happy with gusto ever since. But... I'm a single person who occasionally does payments to subcontractors, not dealing with payroll for dozens/hundreds.
