A serious ticket desk with email, chat, SLAs and a knowledge base; setup is the first ticket.
Email becomes an assigned team inbox with notes and collision warnings; the nicer modules open a wallet.
Tickets, SLAs and a knowledge base in a clean Frappe shell; the five-minute installer still leaves you the pager.
