How do you explain negative churn (expansion revenue) to board auditors who think NRR >100% is impossible?

## Brief
Negative churn = customers pay more than previous term (upsells, add-ons, multi-product). NRR >100% is the revenue outcome. Show contract trails to prove it's real.

## Detail

Board auditors often challenge NRR >100% because it contradicts their experience in non-SaaS businesses. You need transparent proof that expansion is real and not accounting fiction:

**Define Negative Churn Clearly**:
- Traditional churn: Customers leave, revenue declines
- Negative churn: Some customers expand (multi-product, tier-up, seat growth) faster than others churn
- **Net effect**: Customer cohort pays more in year 2 than year 1, creating NRR >100%

**Example**:
- Beginning MRR: 100 customers × $1K = **$100K**
- Churn: 5 customers × $1K = **-$5K** (5% churn)
- Expansion: 40 customers upgrade from $1K to $1.5K = **+$20K**
- Net New ARR: $100K - $5K + $20K = **$115K**
- **NRR = 115%** (expansion offset churn 4:1)

**Audit-Ready Evidence**:
1. **Segment your expansion revenue**:
   - Tier upgrades: Product A→B
   - Seat additions: +10 licenses
   - Multi-product: Add-on attach
   - Each cohort tracked separately

2. **Show contract trails**:
   - Q1 Book: $1M (avg contract $10K)
   - Q2 expansion: $150K new (existing customers)
   - Q2 net new: $180K (fresh logos)
   - Auditor can verify via CRM data

3. **Compare to CAGR**:
   - If revenue is growing at 60% but you claim 110% NRR, auditors will ask if that's driven by expansion or new logos
   - Formula: `CAGR = (Existing Customer Revenue Growth + New Logo Growth) ÷ Total Growth`

Bridge Group research shows:
- **Expansion-driven NRR >120%**: Sticky, high-value product
- **New logo–driven CAGR >100%**: Land-heavy motion (riskier)
- **Healthy mix**: 60% expansion, 40% new (sustainable)

```

**Operator moves**:
- Build dashboard: Expansion revenue by type (tier, seat, multi-product)
- Compare YoY expansion rates by cohort maturity
- Present auditors with 10-customer sample trail (contract A→B showing value increase)
- Set expansion targets: "We aim for 25% of cohort to expand annually, worth +$150K NRR."
