Billing & Usage

  • Billing is applied at the account level, regardless of the number of projects or agents.

  • Charges are based on Conversational Minutes – the total active interaction time between agents and end users.

  • All payments are processed securely via Stripe.

  • The billing dashboard in the Administration Console provides real-time usage, historical invoices, and projected costs.

  • Some advanced features (SSO, premium analytics, custom integrations, Bring-Your-Own LLMs, etc.) are available only on Growth or Enterprise plans.

Best Practices

  • Start with the Free plan to evaluate capabilities and estimate usage.

  • Use the Growth calculator to find the most cost-effective volume and billing options.

  • Monitor usage reports regularly to forecast spend and avoid unexpected overage.

  • Use separate accounts when strict billing separation or compliance isolation is required across divisions.

  • Keep your billing email actively monitored for invoices and important notices.

By choosing the right plan and managing usage effectively, you can scale PromethistAI confidently—from your first agent to enterprise-wide deployments.
