Overview
Harbourline is a six-person property firm handling residential sales across the south coast. Most of their pipeline came through website enquiries and portal listings, and most of it went cold before anyone replied.
When we measured it, the average time to first response was 47 hours. By then the buyer had usually booked a viewing with someone else.
The challenge
The team was not slow because they were lazy. They were slow because enquiries landed in three different places, nobody owned the first reply, and weekends were a black hole.
Leads reached within five minutes are far more likely to convert than those contacted half an hour later. Harbourline was losing that window every single time, and they could feel it in their numbers without being able to point at the cause.
Our approach
We started by mapping every route a lead could take into the business, then collapsed them into a single intake. One front door, one owner, one clock.
Rather than build a rigid script, we designed a system that reads each enquiry, drafts a reply in the firm's voice, and only asks a human to step in when the lead is high value or unusual.
What we built
Every enquiry now flows into one workspace. Within two minutes the system sends a personalised reply that answers the obvious questions and offers a calendar link to book a viewing.
Behind that, each lead is scored against Harbourline's own criteria, so the team knows who to call personally and who is happy to self-serve. The agent never sends anything the firm has not pre-approved in tone and structure.
The results
Average response time dropped from 47 hours to 4 minutes, including overnight and weekend enquiries. Booked viewings rose by 38% in the first month.
The founder got back roughly twelve hours a week that used to go on chasing and re-typing the same replies. More importantly, the firm stopped quietly losing buyers it never knew it had.
