Definition
Win rate is sales effectiveness distilled - though definition discipline matters enormously: measured against SQLs versus all leads produce different truths serving different diagnoses.
Why it matters
Pair win rate with lead volume to locate the constraint: low volume with decent wins needs marketing; flood-and-fail patterns need qualification or sales enablement.
Formula
Deals won / Qualified opportunities
Benchmarks
B2B services: 20-30% from SQL is solid
