Can I draft a new invoice by providing a JSON list of items?

Yes. The `create_invoice` tool allows you to generate a draft invoice for a specific customer. You simply provide the contact ID and a JSON array of line items including names and prices, and the draft will be created in your Zoho account.

How do I find out the total amount due for a specific customer?

You can use the `get_invoice_details` tool for each of the customer's invoices. Your AI agent can help you list all invoices for a contact ID and then retrieve the detailed balance due for each one to give you a summary.

Is it possible to update a customer's company name via chat?

Absolutely. Using the `update_contact` tool, you can instruct your agent to change the contact name or company name associated with a specific ID, ensuring your CRM data is always accurate.
