The helpdesk that ignores revenue
In a pure helpdesk, every customer is the same: one more line in the queue. The account that pays the bills and the one-time requester look identical — because the tool can't tell the difference.
When the CRM lives in the same place, the customer card gains the relationship: the company they belong to, the deals in motion, the whole support history. Nobody starts a conversation from zero — support sees who they're talking to.
