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-based sales management system since 2012. They attempted to migrate to a no-code tool, but experienced unacceptable performance issues with page transitions, data searches, and report generation for actual business operations. With over 1,400 customers, more than 50,000 parts items, and over 50,000 delivery slips, a generic no-code solution was unable to 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, and the company was manually processing complex tasks in Excel—including agent reward calculations, carryover management, quarterly accumulation tracking, and minimum payment threshold determinations. This created constant risks of calculation errors and payment mistakes, along with significant operational burden. The company attempted to resolve these issues using generative AI independently, but lacked the development expertise needed and ultimately abandoned the effort.
Operates online sales with nationwide shipping using a LINE order management tool. As order volume increased, manual tasks such as order organization, order slip creation, and shipping list registration with Yamato Transport grew significantly, making human errors more likely to occur. Attempted to resolve the issue independently using generative AI, but found that it took longer than expected and abandoned the effort.
