Executive Summary

This case study covers a one-week beta pilot within a broader monthly engagement for a service-based Premium Vacuum retailer, combining AutoCall's AI Voice Agent with automated multi-touch SMS follow-up. From a lean list of 159 unique contacts, the system placed 623 calls, held 128 live conversations, and sent 834 follow-up texts, converting 17 booked appointments (a 10.7% contact conversion rate) and directly contributing to $5,000+ premium vacuum sales.

Total trackable revenue reached $13,400+ against a $1,500 monthly campaign cost, a return of roughly 8.93x from just the first week of activity. Following these results, the campaign has since gone live across multiple states in Australia, expanding beyond the initial beta.

The Strategic Challenge

A service-based Premium Vacuum retailer needed to convert a compact, cold lead list into booked sales appointments without adding manual dialing headcount. Outbound calling environments typically see the majority of dials land in voicemail or IVR rather than a live person, and the challenge was to turn a small pool of 159 contacts into qualified bookings, including hesitant or non-committal prospects, using voice and SMS automation alone.

Key Pain Points:

Small, finite lead pool (159 unique contacts) with no room to waste on poor follow-up
High voicemail/IVR rate (79.4% of all dials) typical of outbound calling
Need to convert neutral or hesitant prospects, not just clearly interested ones
No manual sales development team to run repeat dial and SMS cadences

The AutoCall Solution

AutoCall deployed its AI Voice Agent to handle outbound dialing, live qualification, and appointment booking, paired with an automated multi-touch SMS sequence to re-engage contacts who didn't answer or need a nudge before committing.

Solution Architecture:

623 outbound calls placed across 159 unique contacts
128 live conversations handled end-to-end by the AI agent
834 SMS messages sent as automated follow-up touches
17 bookings confirmed directly by the AI

Key Technical Features:

Automated re-dial logic to maximize live contact rate from a fixed lead pool
Multi-touch SMS sequencing layered on top of voice outreach
Real-time sentiment tagging on every live conversation
Direct appointment booking during the call, with no handoff required

Call Sentiment & Conversation Quality

Sentiment	Call Count	% of Total Calls	% of Live Conversations
Positive	10	1.6%	7.8%
Neutral	574	92.1%	89.1%
Negative	17	2.7%	13.3%

The AI agent secured 17 total bookings despite only 10 calls being categorized as explicitly "positive." This shows the system's ability to navigate neutral, hesitant, or inquisitive prospects and still guide them to a booking, rather than relying only on the easiest, most enthusiastic leads.

Performance Evaluation

17 Bookings from 159 Unique Contacts

A 10.7% overall conversion rate from a small, finite lead pool, with no fresh leads added, points to efficient use of the list rather than reliance on raw volume.

13.3% Booking Rate from Live Conversations

Of the 128 live conversations held, more than 1 in 8 converted directly into a booked appointment.

Multichannel Coverage

With 79.4% of calls landing in voicemail or IVR, the 834 automated SMS touches gave the campaign a second channel to recover and convert contacts the voice channel alone would have missed.

Financial Performance & ROI

Financial Metric	Value	Notes
Campaign Cost	$1,500	Full monthly service fee
Minimum Booking Value	$200	Baseline service floor per appointment
Baseline Booking Value	$3,400	17 bookings × $200 minimum
High-Ticket Sales Closed	$10,000+	2+ premium vacuum systems sold @ $5,000+ each
Total Revenue Generated	$13,400+	Baseline booking value plus high-ticket sales
Net Client Profit	$11,900+	Total revenue less campaign cost
Cost Per Booking (CPA)	$22.06	One week's share of the monthly cost ($1,500 ÷ 4) ÷ 17 bookings
Return on Investment	~793% (~8.93x)	Return on campaign spend in week one alone

At a CPA of $22.06 against a $200 minimum booking value, the client was already highly profitable on every booked appointment in the first week, before accounting for the high-ticket sales on top.

Operational Efficiency

Autonomous Operation

No additional sales development headcount required to run 623 calls and 834 SMS touches
Consistent qualification logic and sentiment tagging applied across every conversation
Full reporting on call outcomes, sentiment, and bookings with no manual tracking

Identified Opportunity: Email Channel

AutoCall also recommended layering automated email follow-up alongside the voice and SMS touchpoints, particularly to give the 79.4% of contacts who landed in voicemail or IVR a third way to re-engage. The client did not have email addresses available for this lead list at the time of the beta, so email was not included in this initial run. This remains an identified opportunity for a future phase of the campaign.

Client Testimonial

"We were very impressed and the results brought a return on our investment. We will be expanding this across multiple states now and potentially internationally."

Owner, Premium Vacuum Retailer

Conclusion

In just the first week of a month-long beta, a $1,500 investment converted into $13,400+ of trackable revenue for this Premium Vacuum retailer, an ~8.93x return. On the strength of these results, the campaign has since gone live across multiple states in Australia, moving from a single-market beta to a multi-state rollout.

What's Next?

Scale the multi-state rollout to capture compounding returns from repeat SMS and voice touches across a larger, geographically distributed lead pool
Layer in automated email follow-up once the client's lead lists include email addresses, closing the outreach gap left by the 79.4% voicemail/IVR rate
Benchmark performance state-by-state to confirm conversion rates hold as the campaign scales beyond the original beta market
