Case Studies
Real-world business systems built with vibe coding — all delivered in under 1 month, from ¥300,000.

A customer who has been operating a desktop sales management system since 2012. They attempted to migrate to a no-code tool, but the response times for page transitions, data searches, and report generation were not practical for real-world operations. With over 1,400 customers, more than 50,000 parts items, and over 50,000 delivery slips, a generic no-code solution could not meet their needs.

There was an existing reservation system (external SaaS) incurring over ¥10,000 monthly in running costs, with inadequate direct booking flows from Google Maps and LINE. The clinic faced the challenge of low direct access numbers from patients.

Each affiliate had different commission rates, requiring complex processes such as agent reward calculations, carryover management, quarterly accumulation, and minimum payment threshold determinations—all handled manually through Excel. This created constant risks of aggregation errors and payment mistakes, along with significant manual burden. The company attempted to resolve these issues using generative AI but lacked the development expertise needed and ultimately abandoned the effort.

Operated nationwide shipping online sales using LINE's order management tool. As the number of orders increased, manual work for order organization, order form creation, and shipment list registration with Yamato Transport grew significantly, making human errors more likely to occur. Attempted to solve the issue independently using generative AI, but realized it would take more time than expected and gave up.
