What ROI should a typical HVAC/plumbing/roofing company expect, and what metrics prove it?

ROI varies by lead volume, missed-call rate, and average job value, so the most accurate expectation comes from comparing your “before vs after” funnel metrics. The strongest proof metrics are missed calls recovered, booking rate, speed-to-lead, cost per booked job, and hours saved—validated by call summaries and call-purpose analytics.
