When to stay with Sierra
Documented strengths from our Sierra review — switching isn't always the right call:
- Outcome-based pricing aligns cost with delivered value — you largely pay only for resolved interactions, not access
- Agents take real actions in business systems (returns, subscriptions, payments), not just answer FAQs
- Sierra builds and operates the agents for you rather than handing over a raw toolkit, lowering the setup burden
