B2B Customer Success Manager (CSM) Capacity Limit.

## The Math of Burnout

The CFO often declares: "Every Customer Success Manager (CSM) must hold a $2,000,000 Book of Business!" If the product costs $100,000 a year, the CSM only manages 20 accounts. Highly manageable. But if the product costs $15,000 a year, the CSM must hold 134 accounts.

### FAQ

**Q: Why do accounts churn under high-volume pressure?**
A: If answering standard emails and running Quarterly Business Reviews (QBRs) takes just 2.5 hours per client per month... 134 clients requires **335 working hours** per month. The CSM physically only works 160 hours. They simply stop answering emails from low-value clients, and those clients churn furiously across the board.
