Reasoning
Consolidating opinions by domain (onepagecrm.com, capterra.com, breakcold.com, forbes.com) and weighting by confidence, the majority supports quotes/invoicing. OnePageCRM domain ~0.90 true, Capterra ~0.82 true, BreakCold ~0.60 true, Forbes ~0.90 false. Weighted true ≈ 2.32 vs false ≈ 0.90, giving around 72% confidence in true. Thus the attribute should be true.
