70s Detailer is a premium automotive detailing studio in Indonesia, specializing in detailing, paint protection, and coating services. The brand serves a wide range of customers—from daily drivers to car enthusiasts—and attracts high-intent leads through strong Instagram and short-form video presence.

The problem: Managing WhatsApp conversations at scale

70s Detailer’s strong Instagram and short-form video presence drives a high volume of WhatsApp inquiries each month through click-to-chat ads and organic traffic. However, relying on the WhatsApp Business App limited the team’s ability to properly manage, retarget, and convert these conversations at scale.

Because broadcasts on the WhatsApp Business App are capped at 256 contacts, 70s Detailer struggled to reengage past leads in meaningful volume. Many customers who asked about coating or detailing prices—but weren’t ready to book immediately—went cold and never returned.

Lead status tracking was handled manually, making follow-ups inconsistent across outlets and admins. During peak periods (weekends, promotions, and seasonal campaigns), thousands of incoming messages included general questions, price shoppers, or non-serious inquiries. This overwhelmed admins and reduced focus on high-intent customers ready to book.

Customer data collection was also inconsistent. Admins often had to repeatedly ask for basic information such as car model, service interest, preferred outlet, and language. Without early qualification, chats were routed manually, slowing response times and increasing friction.

Finally, there was no after-hours coverage. Potential customers who messaged at night or outside operational hours—often after seeing ads or social content—received delayed responses. Many of these high-intent prospects booked with competing detailers instead.

The AELYST Solution

70s Detailer adopted WhatsApp API with AELYST to improve lead quality, scale broadcast messaging, and automate customer handling across the entire booking lifecycle. All WhatsApp conversations, Instagram DMs, ad replies, and follow-up broadcasts are now managed from a single unified platform.

By centralizing inbound chats and automation, 70s Detailer is able to qualify detailing and coating inquiries faster, route customers to the right outlet or admin, and reengage past leads at scale—without overwhelming the team.

Automatically capture customer data and route leads

AELYST enables 70s Detailer to automatically capture key customer details at the start of each chat—such as car model, service interest (detailing, coating, PPF), preferred outlet, and language. Based on this information, conversations are routed to the most relevant admin or outlet, ensuring faster responses and better workload distribution across the team.

This early qualification removes the need for repetitive back-and-forth and helps admins focus immediately on providing accurate pricing, availability, and recommendations.

Handle after-hours conversations and lead qualification with AI

An AI Agent greets customers outside operating hours, answers common questions (pricing ranges, service differences, estimated duration), and collects essential booking information before handing off to an admin.

By using AI to handle routine inquiries and filter out low-intent or irrelevant chats, 70s Detailer keeps human admins focused on serious customers—especially during peak periods such as weekends, promotions, and campaign launches.

Send retargeting broadcasts at scale

With WhatsApp API, 70s Detailer can now send high-volume, reliable broadcast messages for promotions, service reminders, follow-ups, and reactivation campaigns.

Broadcasts are segmented based on customer status—new inquiry, quoted, booked, completed service, or inactive—so each customer receives relevant and timely messages aligned with their stage in the booking journey.

Improve ad conversion rates with Meta Conversions API and lower-funnel events

To improve ad efficiency and attract higher-quality leads, 70s Detailer connected Meta’s Conversions API (CAPI) to AELYST to send key events such as qualified inquiry and booking confirmation back to Meta. These cleaner signals help ads reach audiences more likely to convert.

Lower-funnel events are also used to optimize short-form video campaigns, resulting in stronger targeting, higher booking intent, and more consistent lead quality.

With improved event tracking and automation, 70s Detailer maintains a steady flow of high-intent inquiries each month while improving overall conversion rates.

“With AELYST, WhatsApp became a true booking channel for us. AI qualification, smart routing, and targeted broadcasts helped us handle volume without sacrificing service quality—and significantly improved conversions.”
