B2B SaaS Metrics

B2B SaaS metrics are the family of subscription-business indicators — MRR, ARR, NRR, churn, expansion — that measure the business at the account and revenue level, not the visit level.

This family is built for the recurring-revenue model and its logic differs from web analytics: instead of 'how many visits', it asks 'how much stable monthly revenue, what logo churn rate, what net revenue retention'. Its backbone is two numbers — MRR/ARR, which counts recurring revenue, and NRR/GRR, which says whether revenue from existing customers is growing or leaking. The thing constantly gotten wrong is that these metrics cannot be derived from site traffic; their numerator is money and comes from billing and CRM, not the analytics script. What product analytics contributes is the behavioral denominator: which account is active, which feature it adopted, which is going dormant — and those signals, placed beside revenue data, build the B2B metric.
