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. Conversations run by automated test suites also use minutes and appear as Testing minutes in the usage report.
-
All payments are processed securely via Stripe.
-
The billing page shows your usage, your subscription status and your invoice history. See The Billing Page.
-
Some advanced features (SSO, premium analytics, custom integrations, Bring-Your-Own LLMs, etc.) are available only on Growth or Enterprise plans.
The Billing Page
Account → Billing is visible to account Owners only. Below the plan cards, the Billing section shows:
Usage this month |
Your conversational minutes for the period selected in the Minutes Usage report (last 30 days by default). |
Subscription |
The status of your subscription, for example active. Go to payments opens the Stripe portal, where you can update your payment details. If the account has no subscription yet, a Free Tier card with Subscribe is shown instead. |
Minutes Usage report |
A daily chart of Minutes and Testing minutes. Choose From and To dates, or Last 7 days, Last 30 days or Last 1 year. |

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 the email address in your Stripe billing details 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.
