Website & Branding for Blockchain Payments Consortium (Mysten Labs)
Quote Follow-Up Automation for HVAC & Plumbing
Most home-service quotes don’t get rejected, they just go quiet. I built a system that follows up on them automatically.
What it does
Takes each quote through a simple form
Schedules up to 8 timed texts over 30 days
Stops instantly on a reply, a STOP, or a booked/lost update
Uses AI to draft replies to objections, with a human approving every one
Built with safety first
No duplicate texts, even when processes overlap
Only contractor-approved wording is sent
Texts go out only during local business hours
Opt-outs are honored immediately
Stack: n8n, Postgres, Groq, Docker, Twilio
Status: built and tested end to end, ready to pilot.
I build automation systems like this for service businesses. Message me if you’d like one for yours😊 .
