Commitments with a date
Scheduling and reminders so follow-up happens when you said it would.
A complaint in chat becomes a ticket with an owner, a due date and a history. Nothing depends on someone remembering.
Tickets with priority, SLA and escalation, scheduling and reminders, appointment booking and repair orders, with resolution metrics.
After-sales that doesn't get lost in chat
Prioritized tickets, scheduling and appointments on the same platform where you support and sell.

From the sold product to the repair, with warranty check and payment.
The sale does not end at payment: after-sales lives here too.
