EolasFlow uses a credit-based billing system. Credits are consumed by AI voice calls based on duration and the AI providers used. Purchase credits, track your usage, and manage billing from the Usage page.

## Credit System Overview

| Item              | Details                                                           |
| ----------------- | ----------------------------------------------------------------- |
| **Billing Model** | Component-based: each AI service (STT, LLM, TTS) has its own rate |
| **Welcome Bonus** | Free credits for new accounts                                     |
| **Payment**       | Pay-as-you-go via Stripe, or subscription plans                   |
| **Rounding**      | Per-second billing, aggregated per call                           |

## How Credits Are Consumed

Each call uses multiple AI services. Credit cost depends on which providers your assistant uses:

| Component                | Description                                                    |
| ------------------------ | -------------------------------------------------------------- |
| **STT (Speech-to-Text)** | Transcribing customer speech (e.g., Deepgram)                  |
| **LLM (Language Model)** | AI reasoning and response generation (e.g., OpenAI, Groq)      |
| **TTS (Text-to-Speech)** | Converting AI responses to speech (e.g., ElevenLabs, Cartesia) |
| **Telephony**            | Twilio call minutes                                            |

Different providers have different rates. Using Groq LLM + Cartesia TTS costs differently than OpenAI Realtime, for example.
