description: >-
  FOCUS-aligned FinOps view of Vapi. Vapi's billing model is consumption-based per minute of
  voice agent runtime, with pass-through component costs for transcription, LLM, TTS, and
  telephony. Total cost ownership requires tracking each provider in the stack.
notes: Cost optimization on Vapi often means rightsizing the LLM/voice provider stack rather than the Vapi platform fee itself.

  description: Use Vapi call analytics plus underlying provider invoices to assemble total cost per call.
- name: Allocation
  description: Tag assistants and phone numbers to business units so call charges can be split in your FinOps store.
- name: Optimization
  description: Cheaper LLM and TTS providers usually drive far more savings than negotiating the Vapi platform fee.
- name: Accountability
  description: Assign owners for each component vendor (LLM, STT, TTS, telephony) since Vapi pass-through pricing depends on those contracts.
