Customer Success Retention

Customer Success and Retention

Building customer success programs that reduce churn, increase retention, and drive expansion revenue — from onboarding and health scoring through engagement and advocacy.

When to Use

• Building a customer success function from scratch
• Reducing churn and improving retention rates
• Designing customer onboarding and engagement programs
• Implementing customer health scoring
• Driving upsells, cross-sells, and advocacy

Common Pitfalls

1. Reactive vs proactive — waiting for customers to complain instead of monitoring health scores
2. No onboarding structure — customers who don't see value in 30 days will churn
3. Health score without action — scoring is useless without automated triggers for intervention
4. One-size-fits-all — enterprise and SMB customers need different success approaches
5. Success = support — customer success is proactive, support is reactive; they're different functions
6. Not measuring outcomes — tracking activities (calls made) instead of outcomes (customer health improved)

Verification Checklist

• Onboarding program designed with time-to-value milestones
• Customer health score model defined (product, support, engagement, outcomes, sentiment)
• Health score thresholds set (green/yellow/red)
• Churn risk predictors identified and monitored
• Automated triggers for health score changes
• Quarterly business review process established
• Expansion playbooks defined (upsell, cross-sell, advocacy)
• NPS/CSAT survey program active
• Customer success platform configured
