Use these tools to understand recurring revenue, acquisition cost, churn, retention, and payback before making growth decisions.

- Measure churn in both logos and dollars when expansion masks problems.
- Pair CAC, LTV, and payback with the same ARPU and margin inputs.
- Contrast NRR and GRR when upsell flatters headline retention.
