Costs buyers often miss

  • Platform fees or seats that must be paid before usage creates value
  • Pass-through STT, realtime model, TTS, telephony, and orchestration bills that are hard to forecast
  • Credit or character pricing that hides the cost of long calls and long-form audio
  • Manual QA, compliance review, and call summaries that only happen after the expensive mistake
