The `list_invoices` tool provides a list of all invoices, and every field (like Invoice ID or total amount) is validated against a schema. You never get corrupted data. Similarly, calling `list_payments` ensures that payment amounts and dates are correct, preventing silent financial errors in your Python code.

Manage client accounts via the Zoho Billing MCP Server for Pydantic AI.

Use `list_customers` to get a list of clients. The agent then uses `retrieve_customer` to pull details, knowing that every field—from name to address—is typed and validated at runtime. It also gives access to `list_projects`, allowing you to track which billable projects are linked to specific client accounts.
