Destructive or important actions
For operations that modify data, delete data or create any important billing operations, the Billing Assistant requires explicit confirmation to protect against accidental changes. Here is an example:- You: “Terminate subscription for Acme Corp”
- Billing Assistant: “This subscription is currently active ($2,500/month). Type
CONFIRMto proceed.”
CONFIRM to execute destructive actions such as terminating subscriptions, issuing invoices or refunds or removing customers.
Security
The Billing Assistant AI Agent is designed with security as a priority:- Organization-scoped access: You can only query and modify data within your own organization;
- Permission-based: Actions are limited to your account permissions;
- No cross-tenant access: Your data is isolated from other organizations;
- Prompt injection protection: The AI Agent is designed to ignore attempts to bypass security controls; and
- Batch operation limits: To prevent abuse, batch operations are capped and throttled to prevent excessive load.
Conversation history
Your conversations with the Billing Assistant are saved, allowing you to:- Return to previous conversations;
- Maintain context across sessions; and
- Reference past queries and responses.

Tips for best results
- Be specific: “Show invoices over $1,000 from last month” works better than “Show me some invoices”;
- Use follow-ups: After getting a list, ask follow-up questions like “Tell me more about the first one” or “Retry all of these”;
- Specify timeframes: Include date ranges when relevant (“in the last 30 days”, “from Q3”);
- Name entities clearly: Use customer
external_id, invoiceid, or useful identfiers when you have them; and - Chain tasks together: Complete related operations in one conversation to save time.
