Indexing Zoho Invoice Data for LlamaIndex

The `list_contacts` tool returns contact names, IDs, emails, outstanding balances, and unused credits. By indexing this output, you can query past sessions to answer questions like 'Who has the highest outstanding balance?' You build RAG applications where live API data is combined into a searchable index, meaning your AI client doesn't hallucinate when talking about your clients.

Managing Billing Records with LlamaIndex and MCP Server

The `list_invoices` tool provides invoice numbers, amounts, dates, and customer info. Indexing these results means you can ask complex questions like 'What were all the invoices over $500 last quarter?' This gives your AI client a grounded answer based on actual API data, not just general knowledge about billing cycles.

Creating Drafts and Estimates using LlamaIndex

The `create_invoice` tool builds an invoice in DRAFT status after receiving the customer ID and line items. Indexing this capability lets you verify if a required customer exists before running complex billing logic. You can also index `list_estimates` results to answer questions about quote statuses, such as 'Show me all accepted estimates that haven't turned into an invoice yet.'
