Customer Success
定义
Expansion revenue is net new recurring revenue from existing customers — via seat additions, tier upgrades, product add-ons, or usage increases. Expansion is higher-margin and higher-conversion than new-customer acquisition and is the primary driver of negative net churn.
要点
- More efficient than acquisition — expansion close rates often 2-5x new-biz rates
- Drives NRR above 100%
- Typically owned by CSMs or expansion-focused AEs
- Expansion motion differs from net-new sales — value-based vs need-based
示例
A 50-seat customer expands to 75 seats mid-contract, adding $12,500/year to their contract. That's $12,500 in expansion ARR without new customer acquisition.
