Customer Support
SaaS, open source and skills for customer support work — with the limits of each written down.Before you pick
What decides it
Each vendor writes its own definition of 'resolved' — it is both the KPI and the invoice line. Silence windows and verified fixes bill differently.
What to avoid
Grounding on your help centre imports its retired policies. Humans quietly ignore those; the agent quotes them as current — and you are held to it.
What is changing
These are moving from answering to acting — refunds and cancellations written into live systems. Evaluation shifts to write scopes, spend caps and approval gates.
