Support done well is a craft — and a business advantage. Customer Support Excellence is a field guide for leaders building high-performing B2B SaaS support organizations, distilling the philosophy, structures, and daily disciplines that separate great support teams from ticket factories. Across twenty focused sections, it covers the foundations (support's mandate, operating principles, and team design), the execution disciplines (case management, communication, knowledge, escalation and incidents, QA, automation and AI, voice of the customer, and onboarding), the measurement layer (the metrics that matter, tooling, and a five-stage maturity model), and the business of support — segmentation and entitlements, channel strategy, workforce management, cost-to-serve economics, compliance, AI governance, and monetized Premier support tiers. Six ready-to-use appendix templates, from an SLA matrix to a QA scorecard and a 30/60/90 ramp plan, turn the guidance into tools you can adopt today. Written for the leaders who have to scale quality and efficiency at the same time.
