The problem
A dental implant clinic paid for Facebook leads but called them back hours later — by which time many had booked elsewhere or stopped answering.
What we built
- A GoHighLevel → n8n webhook bridge that fires within seconds of a new ad lead
- A Retell AI voice agent that calls unattended, answers questions, qualifies and books into the calendar
- Slack alerts to the team with the call summary
- Every lead and outcome stored in Supabase
- A show / no-show tracker so the team knows who actually arrived
How it flows
From trigger to done, step by step.

What changed

- ✓The team only speaks to qualified, booked patients
Why it matters · industry benchmark
Leads contacted within 5 minutes are 21× more likely to qualify than those contacted after 30 minutes.
