The Challenge

The owner was the default escalation point for every call, schedule change, and estimate. Two office staff couldn't keep up with after-hours emergency intake. Estimates took 2-3 hours each. Commercial prospecting had been postponed for two years because there was simply no time.

The Approach

  1. 01

    Discovery call + workflow mapping — identified 6 specific time drains across dispatch, estimating, and follow-up.

  2. 02

    Quick-Win priority: AI-drafted estimates from voicemail transcripts + photos. Connected to ServiceTitan.

  3. 03

    Implementation tier: automated lead triage, commercial prospect research workflow, review response drafts.

  4. 04

    30-day ROI verification: measured actual hours recovered vs. baseline.

The Results

By day 4, AI-drafted estimates were going out within 15 minutes of the customer's call. By day 30, the owner had reclaimed 14.5 hours/week and had booked 4 commercial walkthroughs that would have never happened under the old system. Tool stack runs under $180/month.

I went from being the middleman for everything — calls, status updates, estimates — to finally having time to go after the commercial accounts I'd been putting off for two years.
