Why founders keep both
NRR can look fine while downgrade dollars leak—GRR hides upsell optimism on purpose.
Open both before you conclude health.
Definitions bite
How you tag churn needs to align with Finance or comparisons break quarter to quarter.
Count expansion only how your ledger defines it.
Operational follow-through
Add quick ratios or churn dollars when contractions swing wildly—even if logos look calm.
