NRR is the single most-watched health metric in subscription business. NRR above 100% means the existing customer base is growing in revenue terms even before accounting for new acquisitions—a powerful signal of product-market fit and customer success effectiveness. NRR below 100% means the customer base is contracting and acquisition must outrun churn just to stand still. RevOps owns the data infrastructure, definitions, and reporting cadence that make NRR a reliable management instrument across sales, customer success, and finance.
