Sierra Agent: Outcome-based pricing tied to agreed results; Sierra also describes blended consumption pricing for routing or greeter interactions.

Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.

A source missing from this directory is not proof that a provider cannot support it.
Use the same representative calls, approved instructions, and escalation rules in both pilots. How does it handle interruption and uncertainty? Which actions can it complete, and which require approval? What context reaches a human during transfer? Record conversation quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Goodcall: Architecture is undisclosed. Confirm fair-use terms, number portability, transfer behavior, languages, and regulated-data handling. Sierra Agent: Public voice detail is limited. Confirm telephony, transfer, recording, retention, language, and exact billable outcome.
