A Christchurch new-build developer was watching hot Meta leads go cold. Not because the ads were not working. Because by the time the SDRs got to them, the buyers had already gone to look at the competitor down the road.
Here is how they fixed it in 14 days, with the numbers.
The client asked to stay anonymous for now, so we have stripped the company name and the specific show home addresses. The data is unchanged.
The Setup
The setup, and what was breaking
The team builds 2 to 3 bedroom townhouses in the southwest Christchurch catchments. Halswell. Rolleston. Wigram. The buyers are mostly first-home buyers on KiwiSaver, looking in the $1m to $1.3m range, browsing Facebook on the couch at 9pm. Meta lead-form ads have been the core acquisition channel for over a year.
Two SDRs handled the call-back queue. They were good. They were also drowning. A weekend's worth of leads would land Monday morning and most would not get a call until Tuesday afternoon. By then, half had already booked a viewing with another developer.
That was the gap they wanted to close. Not lead generation. Lead response time.
The Funnel
What 931 dialled Meta leads produced
In a 14 day pay-as-you-go trial, the AI voice agent called 931 Meta leads. Same day, often within minutes of the form hitting the CRM. Here is what came out the other end.
| Outcome | Count | % of all dials |
|---|---|---|
| Humans answered | 348 | 37% |
| ↳ Qualified prospect | 71 | 7.6% |
| Viewing booked at show home | 49 | 5.3% |
| Tagged for 3 to 6 month follow-up | 22 | 2.4% |
The booking number is the one to focus on. 49 confirmed viewings at the show home, in 14 days, from one channel, with no SDR doing the cold legwork. 69% of every qualified prospect ended the call with a slot in the calendar.
The Math
The math, $7.12 per booked viewing
$7.12 per qualified booked viewing
Total trial spend was $505.70 across 14 days. Divided across the 71 qualified prospects, that is $7.12 each. For a developer selling $1m+ townhouses, the maths does not need rounding.
- Total trial spend (14 days, pay-as-you-go)$505.70
- Cost per dial$0.54
- Cost per answered call$1.45
- Cost per qualified prospect$7.12
- Cost per show-home viewing booked$10.32
The other number that mattered to the team:
21+ hours of SDR time reclaimed
That is roughly 1.5 to 2 weeks of full-time calling the dead numbers, the voicemails, and the "wrong number" replies every Meta list throws up. The two SDRs got those hours back to do what only humans can do: walk a buyer through the floor plan, follow up after a viewing, close.
What Worked
What made it work
Three patterns showed up clearly across the 14 days.
| Objection | Calls | Booked | Booking rate |
|---|---|---|---|
| KiwiSaver and first-home eligibility | 85 | 30 | 35% |
| Property specs (bedrooms, parking, school zones) | 77 | 28 | 36% |
| "Busy, call me back" | 34 | 6 | 18% |
On the KiwiSaver calls the agent walked buyers through the income caps, the deposit thresholds, and the difference between First Home Grant and First Home Partner. On the property spec calls it had the data sheet for every active development and quoted it line by line. On the "busy, call me back" calls it offered an immediate calendar slot for the show home instead of a future call. That last one is lower-rate, expected, but still better than the "we will get back to you on Monday" baseline of essentially zero.
Honest Framing
The honest caveats
Three things to be straight about.
The Pipeline
What's next
On the same conversion rate, an extra month at the same daily volume would book another 100+ viewings. Even at half that rate, the maths still works.
The team has now wired the agent into the lead webhook directly so every Meta form submission triggers a call within minutes of a buyer hitting submit. The 22 "not ready, follow up in 3 to 6 months" prospects are already queued for the next campaign, with the agent opening from the context of the last conversation: "Last time we spoke you said you were saving until winter, just checking in on where you got to."
That is the difference between a one-off lead-response patch and a pipeline that keeps compounding. Same agent. Same patch. Just better timing every cycle.
