Cybozu, Inc. (Headquarters: Chuo-ku, Tokyo; President and CEO: Yoshihisa Aono) announced that it has published a case study on how Japan Engineering Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Yusuke Noju) uses “ki to e” on its customer case study page. Japan Engineering built a cost management system using the cloud service “ki to e,” shortening construction project lead times by 30%, reducing annual construction costs by ¥40 million, and cutting annual overtime by 5,000 hours. Japan Engineering is a construction and engineering company that handles projects ranging from specialized construction work to advanced plant engineering. In the construction industry, profit and loss management is often handled through rough estimates, and deficits are frequently discovered only after project completion. Visualizing profitability has therefore become a major challenge for many companies. Japan Engineering had been using spreadsheet software to manage profit and loss in order to secure reliable profits. However, complicated version control caused rework, and overtime became routine for staff. Fatigue at job sites also contributed to employee turnover, making it urgent to reduce workload and accurately identify cost discrepancies. The company also needed mechanisms to prevent unnecessary orders, increasing the need for flexible system design and accounting integration. In response, the company first considered introducing a packaged core system for the construction industry. However, it found it difficult to adapt its existing workflows to the package specifications and concluded that it needed a system aligned with its own business processes. After reviewing its system requirements, the company selected ki to e, a low-code tool that can integrate with accounting and other systems, based on the requirement that cost data entered into the system could be handled end to end through journal entries. In addition to the flexibility to build a system tailored to
