How we generated ~300 inbound WhatsApp leads at ~€0.50 per lead

Premium product, no digital pipeline

Mandaya Energy sells premium solar and battery systems in Bali — not an impulse product. They sell a higher-ticket solution that requires trust, education, and a real sales conversation.

The challenge was clear: generate real buyer interest without wasting budget on low-quality leads.

Meta ads meets WhatsApp inbound flow

Instead of relying on generic awareness content, we built a simple but highly conversion-focused lead generation system around Meta ads and WhatsApp.

We positioned the offer around a very real pain point in Bali: power cuts, unstable electricity, and the frustration of relying on noisy generators. Then we created ads that made the problem feel urgent and relevant, while showing Mandaya as the premium, reliable solution.

From there, we sent people into an inbound flow designed to create action fast:

• Meta ad
• Instant form
• Direct WhatsApp message from the lead
• Sales conversation with the team

This meant the leads were not just passive form submissions. These were people actively raising their hand, filling out their details, and starting a WhatsApp conversation because they were genuinely interested in the product.

Real buyers, not cold traffic

• Around 300 inbound leads
• At roughly €0.50 per lead
• With a low three-figure ad budget
• For a product in the 4 to 5 figure range

That is what makes this case study so powerful. We were not generating cheap vanity traffic. We were generating hot inbound leads for a premium product, at a cost that gives the business massive room to profit.

This is exactly what we focus on at CCF: not just getting attention, but building simple systems that turn attention into real sales conversations.
