Can I check the status of a specific bill using the agent?

Yes! Use the `get_bill` tool with the Bill ID. Your agent will fetch the latest status, including whether it is unpaid, partially paid, or fully paid.

How do I list all my active vendors in BILL?

Simply ask the agent to `list_vendors`. It will retrieve the directory of all business vendors registered in your BILL account.

Does the integration support paying bills directly through the agent?

No. For security and to comply with MFA requirements for financial transactions, the current toolset is focused on querying and auditing (listing bills, checking statuses). Initiating payments must be done through the official BILL platform.
