Existing customers are your fastest growth path.
New customer acquisition costs 5-10x more than expansion revenue from existing customers. You'll learn net revenue retention (are your existing customers generating more revenue this year than last?), expansion MRR (how to upgrade customers to higher-value plans), customer health scoring (which accounts will churn if you don't intervene?), and NPS (net promoter score — will they recommend you?). By the end, you'll know exactly which accounts to focus on and why a 10% improvement in retention is worth more than a 50% improvement in new sales.
Net revenue retention measures how much recurring revenue you keep and expand from existing customers. Learn the formula, benchmarks, and why investors care.
