A replacement-focused shop cut quote turnaround from three days to same-day.

Great Lakes technicians were strong in the field but estimates piled up on their phones until end of day, sometimes end of week. Homeowners comparing replacement quotes rarely waited that long. The shop wasn't losing on price or workmanship, it was losing on speed, and nobody had measured that until it started costing real money.

The bottleneck

Estimates depended on a technician typing up notes after their last job of the day, which usually meant estimates went out one to three days after the site visit, sometimes longer during busy weeks.

The owner estimated they were losing close to a third of replacement bids to competitors who simply quoted faster, not cheaper, based on follow-up calls with homeowners who'd already signed elsewhere.

Financing reminders were inconsistent, so some qualified homeowners never got a nudge toward approval before choosing someone else, even after expressing real interest on-site.

Technicians were effectively doing two jobs, the install work and the paperwork, and the paperwork always lost to the next scheduled call.

The workflow

AI Quoting now pulls the technician's voice notes and site photos right after the visit and assembles a structured draft estimate automatically, matched against Great Lakes' current equipment pricing and install specs.

The office reviews and sends instead of writing from scratch, cutting the writing step down to a five-minute check instead of a from-scratch buildout.

Financing reminders go out automatically to homeowners who haven't responded within a set window, timed to land before the typical competitor's second follow-up.

Every quote still passes through an owner review step before it reaches the customer, so nothing goes out unchecked, and the owner can override pricing on any job without touching the underlying system.

The bid doesn't win because it's the cheapest, it wins because it's the one that showed up in their inbox first. That's the whole game now.

Lessons learned

Scope

Automate the draft, not the decision

The agent assembles the estimate, but a person still reviews and sends it. Keeping a human in the loop on anything customer-facing and price-related builds trust with the team fast, and it means the owner never has to explain a number he didn't approve.

Change Management

Sell the tool as less paperwork, not more process

Technicians didn't resist this rollout because it removed a task they hated instead of adding one. If you want field staff to actually use a new system, make sure their first experience with it is something disappearing off their plate, not something new landing on it.

Trust & Guardrails

Let the owner keep the pen on pricing

Every quote still routes through an owner review step, and pricing overrides are simple and visible. Speed only helps if the numbers stay right, so the fastest fix is the one that never asks you to give up control of the thing you care most about.

What to Automate First

Find where speed, not skill, is losing the job

Great Lakes wasn't losing bids on quality, they were losing them on response time. Before automating anything, figure out whether you're actually competing on speed, price, or trust, because the fix looks completely different depending on the answer.

My techs used to grumble about paperwork every single day. Now they take photos and talk into their phone for thirty seconds, and the quote's basically written by the time they're back in the truck.
