CallNow.au

Project Overview

Australian tradespeople, health practitioners, and service providers lose thousands of dollars in revenue every year to missed calls. When a potential customer rings and no one answers, they call the next business on Google — and that lead is gone forever.

CallNow.au eliminates this problem entirely. The platform provides an AI receptionist that answers every call with natural voice conversation, qualifies leads, books appointments, and sends SMS follow-ups — all without human intervention. But it goes far beyond call handling.

The system auto-generates professional business websites with suburb-specific landing pages for local SEO, manages Google Ads and Facebook campaigns from a unified marketing hub, syncs bookings to Google Calendar, and gives business owners a complete CRM with call transcripts and recordings. A companion mobile app puts the entire dashboard in their pocket.

Built as a multi-tenant B2B SaaS platform, CallNow targets ABN-registered Australian businesses that need enterprise-grade automation without the enterprise price tag.

Impact & Results

CallNow ensures every inbound call is answered, qualified, and converted into a tracked lead — eliminating the revenue leakage that costs small businesses an estimated $1,200+ per month in lost opportunities from missed calls alone.

The platform consolidates tools that would otherwise cost hundreds of dollars per month across separate vendors — receptionist services, website builders, booking systems, CRM, and advertising platforms — into a single subscription starting at $99/month.

At scale (~1,000 customers), the platform delivers unit economics of approximately $5 per customer per month against $99–$200 monthly pricing tiers, yielding 90%+ gross margins. Australian businesses gain 24/7 lead capture, automated local SEO, and multi-channel marketing management without hiring receptionists, web developers, or marketing agencies.
