AI Voice Agent for a US Home Services Business

Brightpath Plumbing · Local Services · United States · Engagement: 7 weeks · Team: 3-person WOW pod

The challenge

Brightpath Plumbing was missing an estimated 40% of inbound calls, especially after 5pm and on weekends — when most emergencies happen. Their answering service booked appointments incorrectly a third of the time and cost $2,400/month. The owner was fielding calls himself on job sites, which meant messy scheduling and lost jobs to competitors.

What we built

WOW built a voice agent on Vapi with a GPT-4o backend, trained on Brightpath’s service catalog, pricing bands, and scheduling rules. The agent answers every call, qualifies the job (emergency vs. scheduled, service type, ZIP code coverage), quotes ballpark pricing where policy allows, and books directly into ServiceTitan via API. Complex or high-value calls are warm-transferred to the owner with a live summary. Every call is transcribed, tagged, and reviewed weekly to refine handling of edge cases.
