Fill up, send in the receipt, win a prize in the draw. Using LINE — the app closest to daily life in Japan — to naturally draw out a driver’s “let’s come back again.” KAITECH built exactly that promotion engine.

■ The Challenge

The gas-station operator wanted a way to keep encouraging drivers to return after filling up. With traditional flyers and paper campaigns, delivery was hard to control and impact hard to measure, and the connection with a driver who filled up once broke off on the spot. They needed a promotion platform drivers could join effortlessly and the operator could keep reaching through — anchored in LINE, an app already part of daily life.

■ Our Approach

KAITECH built a LINE-based promotion system for drivers. Starting from a low-barrier mechanism — upload a fuel receipt, receive a lottery ticket, win a prize in the draw — we extended it with announcements and coupon delivery. We handled the whole build: basic and database design, AWS infrastructure, UI design, coding, testing and the user manual. KAITECH has also built LINE marketing-support systems elsewhere, accumulating know-how in LINE-anchored promotion and customer engagement.

■ Results & Highlights

  • Receipt-and-lottery gamification lowered the barrier to join while driving repeat visits.
  • Announcements and coupons over LINE built a customer channel that doesn’t break off after the fill-up.
  • Achieved the delivery control that paper campaigns could not.
  • Delivered the promotion platform end to end, from basic design to the user manual.
  • Designed on the strength of our LINE marketing-support experience.

■ Why KAITECH Was The Right Fit

Marketing results come not from an impressive strategy but from executing, reading the numbers and improving quickly. Because KAITECH keeps a development team in-house, we can carry a promotion from concept through implementation to post-launch changes ourselves — analysis actually leads to action. Our strength is designing around LINE, widely used in Japan, to build mechanisms tied directly to a concrete outcome: the repeat visit.
