Workflow
1. Diagnose Stage & Need
Ask: "Where are you in your customer success journey?"
| Stage | Signals | Focus |
|---|---|---|
| Early-stage (1-100 customers) | Founder handles support, no formal processes | → Lightweight onboarding, manual health checks |
| Growth (100-500 customers) | Can't personally know every customer | → Systematize onboarding, implement health scoring |
| Scale (500+ customers) | Building CS team, need playbooks | → Full CS org, automation, QBRs |
Primary Need Identification:
| Need | Signals | Next Step |
|---|---|---|
| Onboarding | "Customers don't activate", "time to value is long" | → Step 2: Onboarding |
| Churn | "Customers leaving", "high churn rate", "why are we losing customers?" | → Step 3: Churn Prevention |
| Satisfaction | "Need NPS", "measure satisfaction", "customer feedback" | → Step 4: NPS & CSAT |
| Health Scoring | "Predict at-risk customers", "proactive CS" | → Step 5: Health Scoring |
| Support | "Support process", "ticketing", "QBRs" | → Step 6: Support & QBRs |
2. Onboarding
Transform new customers into successful, activated users. See references/onboarding.md for complete templates.
Onboarding Framework
The Goal: Deliver first value as fast as possible.
Signup → First Value Moment → Habit Formation → Expansion
(Time-to-value) (Stickiness) (Growth)
Define Your Activation Moment:
| Business Type | Typical Activation | Why |
|---|---|---|
| B2B SaaS | First workflow completed | Core value realized |
| Collaboration tool | Team member invited | Network effect |
| Analytics | First report generated | Insight delivered |
| Marketplace | First transaction | Both sides connected |
Onboarding Stages
| Stage | Goal | Timeframe | Key Actions |
|---|---|---|---|
| Welcome | Set expectations | Day 0 | Welcome email, account setup |
| Setup | Configure product | Day 1-3 | Core settings, integrations |
| Activation | Reach first value | Day 3-7 | Guided workflow, first success |
| Engagement | Build habit | Day 7-30 | Feature education, check-ins |
| Expansion | Deepen usage | Day 30+ | Advanced features, team growth |
Stage-Appropriate Onboarding
Early-Stage (Manual, High-Touch):
- Personal welcome call for every customer
- White-glove setup assistance
- Direct founder/CEO communication
- Learn what customers actually need
Growth (Hybrid):
- Self-serve for SMB, high-touch for enterprise
- Automated email sequences with personal check-ins
- In-app guidance (tooltips, checklists)
- Segment by customer size/value
Scale (Automated with Exceptions):
- Fully automated self-serve onboarding
- Tech-touch for most, high-touch for strategic accounts
- CSM assignment based on ARR threshold
- Onboarding metrics dashboard
Onboarding Email Sequence
| Timing | Purpose | Key Elements | |
|---|---|---|---|
| Welcome | Immediately | Confirm, set expectations | Login link, what's next, support contact |
| Quick Win | Day 1 | Drive first action | One specific task to complete |
| Setup Help | Day 3 | Remove friction | Common setup issues, FAQ link |
| Activation Push | Day 5 | Drive to value moment | "Here's what successful users do first" |
| Check-in | Day 7 | Personal touch | "How's it going? Questions?" |
| Feature Intro | Day 14 | Deepen engagement | One underused feature |
| Success Story | Day 21 | Social proof | Customer similar to them |
| Expansion | Day 30 | Grow usage | Team features, advanced use cases |
Onboarding Metrics
| Metric | Formula | Target |
|---|---|---|
| Time to First Value | Days from signup to activation | <7 days (SaaS) |
| Activation Rate | Users reaching activation / Total signups | >60% |
| Onboarding Completion | Users completing all steps / Total signups | >80% |
| Day 7 Retention | Active day 7 / Total signups | >40% (B2B) |
3. Churn Prevention
Stop customers before they leave. See references/churn-prevention.md for intervention playbooks.
Understanding Churn
Types of Churn:
| Type | Cause | Prevention |
|---|---|---|
| Voluntary | Customer decides to leave | Value delivery, engagement |
| Involuntary | Payment failure | Dunning emails, payment recovery |
| Downgrade | Reduced spend | Demonstrate value, right-size plans |
Churn Timing Patterns:
| When | Likely Cause | Intervention |
|---|---|---|
| First 30 days | Poor onboarding, no value found | Activation focus, onboarding calls |
| At renewal | Didn't see ROI | QBR before renewal, value recap |
| After price increase | Price/value mismatch | Communicate value, offer options |
| After champion leaves | Relationship-dependent | Multi-thread contacts |
Churn Analysis Framework
Step 1: Calculate Churn Rate
Monthly Logo Churn = Customers lost / Customers at start of month
Monthly Revenue Churn = MRR lost / MRR at start of month
Net Revenue Retention = (MRR at end + expansion - churn) / MRR at start
Step 2: Segment Churn
Analyze churn by:
- Customer segment (SMB/Mid/Enterprise)
- Tenure (first 90 days vs. established)
- Acquisition channel
- Plan type
- Use case / vertical
Step 3: Identify Patterns
| Question | What It Reveals |
|---|---|
| When do they churn? | Onboarding vs. renewal problem |
| Who churns? | Segment fit issues |
| What predicts churn? | Leading indicators |
| Why do they say they're leaving? | Root cause |
Churn Intervention Playbook
| Risk Level | Indicators | Action | Owner |
|---|---|---|---|
| Critical | Cancellation request, angry ticket | Same-day call, escalate | CS Leader |
| High | Usage dropped >50%, no login 14+ days | Outreach within 24h | CSM |
| Medium | Usage declining, support tickets up | Automated + personal touch | CSM/Automated |
| Low | Minor engagement dip | Automated nurture | Automated |
Exit Survey
When customers churn, learn why:
Exit Survey Questions:
-
What was your primary reason for canceling? (Required, single select)
- Found a better alternative
- Too expensive
- Missing features we needed
- Didn't use it enough
- Poor customer support
- Company/budget changes
- Other
-
What could we have done differently? (Optional, open text)
-
Would you consider us again in the future? (Required, Yes/No/Maybe)
-
How likely are you to recommend us to others? (NPS scale)
4. NPS & CSAT
Measure and improve customer satisfaction. See references/nps-csat.md for survey templates.
NPS (Net Promoter Score)
The Question:
"On a scale of 0-10, how likely are you to recommend [Product] to a friend or colleague?"
Scoring:
- Promoters (9-10): Loyal enthusiasts who refer others
- Passives (7-8): Satisfied but vulnerable to competition
- Detractors (0-6): Unhappy customers who can damage brand
NPS Calculation:
NPS = % Promoters - % Detractors
Range: -100 to +100
NPS Benchmarks:
| NPS Score | Rating | Context |
|---|---|---|
| 70+ | World-class | Top companies (Apple, USAA) |
| 50-69 | Excellent | Strong customer loyalty |
| 30-49 | Good | Healthy, room to improve |
| 0-29 | Needs work | More detractors than ideal |
| Negative | Critical | Urgent action needed |
B2B SaaS NPS Benchmarks:
| Segment | Median | Top Quartile |
|---|---|---|
| SMB | 30 | 50+ |
| Mid-market | 35 | 55+ |
| Enterprise | 40 | 60+ |
CSAT (Customer Satisfaction Score)
The Question:
"How satisfied are you with [specific interaction/product]?"
Scale: 1-5 or 1-7
CSAT Calculation:
CSAT = (Satisfied responses / Total responses) × 100
"Satisfied" = top 2 scores (4-5 on 5-point scale)
When to Use Each:
| Metric | Best For | Timing |
|---|---|---|
| NPS | Overall relationship, loyalty | Quarterly, after key milestones |
| CSAT | Specific interactions | After support ticket, after onboarding |
| CES | Ease of experience | After specific task completion |
NPS Survey Implementation
Timing Strategy:
| Trigger | Rationale |
|---|---|
| Quarterly | Regular pulse on relationship |
| Post-onboarding (Day 30) | Measure first impression |
| Post-support resolution | Measure support quality |
| Pre-renewal (60 days out) | Identify at-risk before too late |
Follow-up Questions (by segment):
For Promoters (9-10):
"What do you love most about [Product]?" "Would you be open to leaving a review or being a reference?"
For Passives (7-8):
"What would make you rate us higher?" "What's one thing we could improve?"
For Detractors (0-6):
"We're sorry to hear that. What's the main reason for your score?" "What would it take to improve your experience?"
NPS Follow-up Workflow
| Segment | Response SLA | Action | Owner |
|---|---|---|---|
| Detractors | 24 hours | Personal call, understand issue | CSM/CS Leader |
| Passives | 48 hours | Email follow-up, gather feedback | CSM |
| Promoters | 1 week | Thank you, referral/review ask | CSM/Marketing |
5. Customer Health Scoring
Predict and prevent churn before it happens. See references/health-scoring.md for detailed models.
Health Score Components
Build a composite score from multiple signals:
| Category | Weight | Signals |
|---|---|---|
| Product Usage | 40% | Login frequency, feature adoption, breadth of use |
| Engagement | 25% | Support tickets, NPS responses, event attendance |
| Relationship | 20% | Executive sponsor, champion strength, multi-threading |
| Financial | 15% | Payment history, contract value, expansion potential |
Simple Health Score Model
For Early-Stage (Spreadsheet-Based):
| Dimension | Red (0 pts) | Yellow (1 pt) | Green (2 pts) |
|---|---|---|---|
| Login Frequency | No login 14+ days | 1-2x/week | 3+ times/week |
| Feature Adoption | Only 1 feature | 2-3 features | 4+ features |
| Support Sentiment | Negative tickets | Neutral | Positive/none |
| Stakeholder Access | No response | Single contact | Multi-contact |
| NPS Score | Detractor | Passive | Promoter |
Score Interpretation:
- 8-10: Healthy (Green)
- 5-7: Needs attention (Yellow)
- 0-4: At risk (Red)
Stage-Appropriate Health Scoring
Early-Stage (1-100 customers):
- Manual health check spreadsheet
- Gut feel + basic usage data
- Review weekly with founder
- Focus on learning patterns
Growth (100-500 customers):
- Simple scoring model in CRM
- Automated alerts for red accounts
- Weekly health review meeting
- Start documenting playbooks
Scale (500+ customers):
- Automated health scoring platform
- ML-based churn prediction
- Real-time dashboards
- Tiered response playbooks
Acting on Health Scores
| Health | Action | Frequency | Goal |
|---|---|---|---|
| Green | Expansion focus | Quarterly QBR | Grow and advocate |
| Yellow | Engagement boost | Bi-weekly check-in | Return to green |
| Red | Intervention | Immediate | Save or learn |
6. Support Processes & QBRs
Build support systems that scale. See references/support-processes.md for templates.
Support Tier Structure
| Tier | Handles | Response Time | Escalation |
|---|---|---|---|
| Tier 1 | FAQs, how-to, basic issues | <4 hours | Can't resolve in 1 interaction |
| Tier 2 | Technical issues, bugs | <8 hours | Requires engineering |
| Tier 3 | Engineering escalation | <24 hours | Product decisions needed |
Support Metrics
| Metric | Definition | Target |
|---|---|---|
| First Response Time | Time to first human reply | <4 hours (business) |
| Resolution Time | Time to fully resolve | <24 hours (Tier 1) |
| First Contact Resolution | % resolved in one interaction | >70% |
| CSAT (Support) | Post-ticket satisfaction | >90% |
| Ticket Volume per Customer | Tickets / Active customers | Decreasing trend |
