Invoice Investigator

Build a complete charge + payment timeline for a customer or specific invoice. Designed for dispute resolution.

Step 1 — Resolve the subject

If $ARGUMENTS looks like an invoice number (starts with INV):

• ZohoBilling_Get_an_Invoice with that invoice ID
• From the invoice, extract the customer ID

If $ARGUMENTS is a customer name:

• ZohoBilling_Search_Customers with search_text: $ARGUMENTS
• Confirm if multiple results. Proceed with customer_id.

If $ARGUMENTS is empty: ask "Which customer or invoice number should I investigate?"

Step 2 — Fetch all linked records (in parallel)
