Like ADP, Paychex routes accounts through dedicated representatives. Multiple customers describe being effectively stranded when a good rep leaves or is reassigned, with no mechanism to request a change.
Paychex's BBB profile shows a high volume of complaints concentrated on billing errors, payroll calculation mistakes, and difficulty cancelling services. The complaint pattern has been consistent over multiple years.
Paychex customers consistently describe additional fees emerging after contract signing — per-form fees, year-end processing charges, and state-specific compliance fees that weren't in the original quote.
State tax payment errors and late filings attributed to Paychex are a recurring thread across payroll forums — employers receiving penalty notices for miscalculated state UI rates and missed filing deadlines.
