Paychex uses a Sierra agent for transactional payroll calls such as entering hours. Sierra reports early results of 95% positive client satisfaction and 93% positive customer effort scores.

Outcomes are reported exactly as stated by the source; we have not independently audited them.

How it works

  1. Agent handles transactional payroll requests by phone.
  2. Service reps focus on complex cases.

Risks & compliance

  • Wrong or hallucinated answers to customers; needs guardrails and handoff
  • Vendor-published results; not independently audited
  • Regulated financial disclosures and identity verification
