Where the money leaks today

The admin that quietly costs you jobs

  1. Portal enquiries left in a shared inbox

    REA and Domain enquiries sitting in a shared inbox until Monday morning.

  2. Open-home callbacks done two days late

    Scan-in data manually entered, then SMS callbacks done two days after the inspection.

  3. Vendor reports hand-typed on Sundays

    Weekly written updates hand-typed on Sunday nights, often skipping a week when life gets busy.

  4. Listing copy written at 9pm

    Descriptions written late at night; social tiles built in Canva by the sales associate.

  5. Past buyers left to rot in the CRM

    Past buyer enquiries left untouched after they didn't bid on one listing.

  6. Appraisal requests leaking overnight

    'Find an Agent' form requests sitting unanswered for 24+ hours.

~$1,840 per enquiry

Every Domain or REA enquiry left for 2+ hours costs an average Melbourne office ~$1,840 in lost GCI / Zatersio Real Estate Sales Blueprint · May 2026

The solution stack

One core agent, four compounding add-ons

Core

Listing-to-Lead Engine

Three things in one. An AI voice and SMS responder picks up every REA/Domain portal enquiry in under 90 seconds, qualifies the buyer on price range, finance and timeline, and books an inspection straight into your agent's calendar. Open-home scan-in data flows into a personalised SMS within 15 minutes. And the AI drafts the weekly written vendor report per listing for the agent to review and send.

Every reply is compliant with the 2026 Victorian underquoting and reserve-disclosure rules: comparable sales, indicative price and suburb median are auto-attached. The principal stays in control of every send.

ValueRecover the equivalent of one extra sale per quarter (avg ~$20,200 GCI in Vic) and Core pays for itself in week one of the next listing.

AI Listing Copywriter

Generates branded property descriptions, 'Just Listed / Just Sold' social tiles and eDM blasts in your office's tone of voice. One brief in, full marketing pack out.

ValueSaves the principal or sales associate 3-4 hours per listing.

Appraisal Bot

Domain or REA 'Find an Agent' form lands and becomes an instant qualified booking. The AI captures address, property circumstances and vendor motivation, then books the appraisal into your diary with a personalised intro SMS.

ValueCaptures appraisal requests that currently leak overnight; conversion lifts dramatically.

Open-Home Follow-Up Automation

The scan-in app feeds the AI; every attendee receives a personalised SMS within 15 minutes thanking them, sharing comparable sales and inviting a follow-up call or private inspection.

ValueCuts 'who was that couple at the open?' admin to zero and accelerates buyer warming.

Buyer Database Re-engagement Agent

Re-warms stale CRM contacts who enquired on past listings. The AI matches their original criteria against new stock, sends a tailored SMS and books an inspection or callback when interest returns.

ValueRe-converts the silent majority of your database into active buyers without sales-agent time.

How we work together

From first call to live in six weeks

  1. Week 1

    Discovery

    Two 60-minute sessions with the principal and a lead agent or PM. We map your enquiry handling, vendor reporting and tenant comms, and check how Agentbox, VaultRE, Rex, PropertyMe or PropertyTree holds your listings, contacts and trust account before we lock scope.

  2. Weeks 2-4

    Build

    We train the agent on your buyer-qualifying and tenant-triage flows, build vendor-report drafting from your CRM data, and wire enquiry capture and updates back into Agentbox, VaultRE, Rex or your PM platform. You see test enquiries and draft reports each week.

  3. Week 5

    Pilot

    Live with one sales agent or one PM team. We check buyer enquiries are qualified and booked, vendor reports draft correctly, and the tenant inbox quietens without missing an urgent maintenance call, then tune in flight.

  4. Week 6 onward

    Retainer

    Roll out across the office. The monthly retainer kicks in: we own uptime, watch enquiry-response and vendor-report numbers, retune as listing volume and your rent roll change, and add the next automation when you're ready.

Integrate, never replace

We sit on top of the tools you already run

Agentbox, VaultRE, Box+Dice, Rex, PropertyMe, PropertyTree, Console and Ailo already store your data and process your trust account. We sit on top via their APIs and do the things they don't: answer the enquiry, qualify the buyer, draft the vendor report, quiet the tenant inbox, and never replace what's working.
