ROI Analysis — 12 months. Investment: $15,000. Returns: time savings 20 hrs/wk × $50 × ~52 wks = $52,000/yr; conversion lift 15% on $40K/mo lead revenue ≈ $6,000/mo × 12 = $72,000/yr. Total annual benefit ≈ $124,000. Net gain $109,000. Simple ROI = ($124,000 − $15,000) / $15,000 = 727%. Payback period ≈ 1.5 months. Verdict: strongly positive; primary risk is realizing the full 15% conversion lift — model a conservative 7% case at 360% ROI.
