Executive Summary
Business owners do not care which ad got the most clicks or which voucher was redeemed the most. They care about which customers become valuable. The biggest finding is that long-term value comes from repeat customers and a small group of whales, not from the first visit.
A Free Engine Check customer returns 84% of the time and is worth RM2,519 over their lifetime. An RM50 Voucher customer returns only 28% of the time and is worth RM621. The difference in customer value largely comes from the difference in repeat behaviour. The first visit hides this completely.
The same pattern appears across locations. A Klang Valley customer is worth nearly twice a Johor customer. Repeat visits generate 60% of revenue, while the top 10% of customers generate 49%. The offers that create repeat customers and whales are the offers that grow the business.
This changes the question from cost to value. Put more budget into the promotions that create valuable customers, especially Free Engine Check, Air-Cond packages, and referral programmes. Stop spending on promotions that do not create valuable customers, particularly the RM50 Voucher in Johor and Penang.
With a 40% margin, the business can spend up to 30% of a customer's first-year value to acquire them. That leaves plenty of room to invest more in the offers that work while avoiding unnecessary spending on low-value customers.
