Execution Flow

Step 1: Retrieve Customer Payment Info

stripe.get_customer({
  customer_id: "{customer_id}",
  expand: ["default_source", "invoice_settings.default_payment_method"]
})

Step 2: List All Payment Methods

stripe.list_payment_methods({
  customer: "{customer_id}",
  type: "card"
})

Step 3: Analyze Payment History

analytics.get_metrics({
  customer_id: "{customer_id}",
  metrics: ["payment_success_rate", "failure_reasons", "retry_outcomes"],
  period: "12m"
})

Step 4: Update Default Method (if needed)

stripe.update_customer({
  customer_id: "{customer_id}",
  invoice_settings: {
    default_payment_method: "{best_payment_method_id}"
  }
})

Step 5: Send Expiration Notice (if needed)

messaging.send_email({
  template: "card_expiring",
  to: "{customer_email}",
  variables: {
    card_last4: "{last4}",
    expiry: "{exp_month}/{exp_year}",
    update_link: "{update_payment_link}"
  }
})

| [Type] | [XXXX] | [MM/YY] | [Active/Expiring/Expired] |

### Risk Assessment
**Failure Risk**: [Low/Medium/High]

| Risk Factor | Status | Impact |
|-------------|--------|--------|
| Card Expiration | [X] days | 🟢/🟡/🔴 |

|-------|----------|-----------|----------|---------|
| [Month] | [X] | [Y] | [Z] | [W] |

**Common Failure Reasons**:
1. [Reason] - [X]% of failures
2. [Reason] - [X]% of failures

### Recommendations

#### High Priority
1. **[Action]**
   - Why: [Rationale]
   - Impact: [Expected improvement]
   - Steps: [How to implement]

#### Medium Priority
2. **[Action]**
   - Why: [Rationale]
   - Impact: [Expected improvement]

### Cost Optimization
| Current | Optimized | Savings |
|---------|-----------|---------|
| $[X] processing fees | $[Y] projected | $[Z]/year |

**Recommendations**:
- Switch [X]% of volume to ACH: Save $[Y]/year
- Enable network tokens: Reduce declines by [X]%
- Add backup payment method: Recover $[X]/year in failed payments

### Automated Actions Taken
- [x] Scheduled card expiration reminder for [Date]
- [x] Enrolled card in automatic card updater
- [ ] Pending: Customer add backup method

### Next Steps
1. [Immediate action]
2. [Follow-up action]
3. [Long-term optimization]

Guardrails

• Never store or log full card numbers
• Request new payment method at least 30 days before expiration
• Do not retry failed payments more than 4 times
• Escalate high-value customers ($10K+ MRR) to human for failed payments
• Respect regional payment preferences (SEPA, iDEAL, etc.)
• Comply with PCI-DSS requirements at all times
