FAQ

Questions Invoice Ninja owners ask.

  • 01

    Can I create a new invoice draft through my agent?

    Yes. Use the create_invoice capability by providing an existing Client ID and a JSON array of line items. Your agent will generate the draft in Invoice Ninja, ready for your final review and sending.

  • 02

    How do I check a client's outstanding balance?

    The get_client capability allows your agent to retrieve complete details for a specific client, including their current balance and payment history. This helps you quickly identify which clients need follow-up on outstanding payments.

  • 03

    Can my agent list all unpaid invoices?

    Absolutely. Use the list_invoices capability to browse your billing system. Your agent can filter through the results to show you which invoices are still in 'Sent' or 'Overdue' status directly through natural conversation.
