The challenge: 25-30% of calls going to voicemail while the team was out on site

GreenLeaf Property Maintenance provides gardening, cleaning, handyman, and general maintenance services to residential and commercial clients across Perth. The company has 14 field operatives and one office coordinator who managed all inbound calls.
The problem was predictable: the office coordinator couldn't keep up. During peak periods, 25-30% of calls went to voicemail. Field operatives were frequently pulled off jobs to answer their mobiles when the office line was engaged. Every missed call was a potential booking lost to a competitor who picked up faster.
The coordinator spent 6 hours a day on the phone, leaving almost no time for scheduling optimisation, invoicing, or supplier management. Hiring a second coordinator would cost $65,000 AUD per year.

The solution: Every call answered on the first ring, repeat clients recognised by phone number

Thrumble AI handles all inbound booking and inquiry calls. The AI answers every call on the first ring, in a natural Australian English voice, and walks the caller through a structured booking flow: service type, property address, preferred date and time, access details, and any special requirements.
For quoting requests that require an on-site assessment, the AI books a quote visit and captures photos or descriptions of the work via an SMS link sent during the call.
Repeat clients are recognised by phone number, and their property details and service history are referenced during the conversation, giving callers a personalised experience.

The results: The numbers speak for themselves

• 1,100 job bookings processed per month through AI calls.

• Zero missed calls. The 25-30% voicemail rate dropped to 0%.

• Field operatives are no longer interrupted. On-site productivity improved, with an estimated 45 minutes per operative per day recovered.

• Average booking call duration: 1 minute 50 seconds, down from 5 minutes 20 seconds with the coordinator.

• 88% of calls fully resolved autonomously. 12% routed to the coordinator for complex quoting or commercial contract inquiries.

The commercial impact: $110K saved. Monthly bookings up 28%.

$110,000 AUD per year saved by not hiring a second coordinator, plus the existing coordinator now has 6 hours per day freed up for scheduling, invoicing, and business operations.
The elimination of missed calls has increased monthly booking volume by 28%, worth an estimated $185,000 AUD in additional annual revenue.
