Transforming Sales Structures: How Kokusai Kogyo's EneGaeru Biz Changed Kyoshin Koken's Operations

Transforming Sales Structures: The Impact of EneGaeru Biz on Kyoshin Koken



In a transformative move within the solar energy sector, Kokusai Kogyo Co., Ltd. has introduced its innovative economic effect simulator, EneGaeru Biz, to Kyoshin Koken Co., Ltd., a company specializing in solar power generation and storage battery installations based in Aichi Prefecture. Over the course of just three years since its implementation, the simulator has significantly restructured the company's sales operations, producing over 1,000 projects annually without incurring advertising expenses and drastically shortening proposal lead times.

Challenges Faced by Kyoshin Koken


Before the adoption of EneGaeru Biz, Kyoshin Koken encountered three primary challenges that hindered their sales processes:

1. Lengthy Lead Times: Reliance on manufacturers and trading companies for estimating and simulating industrial solar energy solutions meant that initial proposals took between one to one and a half months.

2. Data Acquisition Barriers: Over 60% of initial inquiries faced difficulties in obtaining demand values (electricity consumption data) within a 30-minute window, leading to stagnation in proposals.

3. Loss of Time on Re-proposals: Negotiations based on numeric adjustments like overload rates and optimal panel capacities resulted in a loss of an additional one to one and a half months every time a client request for alterations necessitated a new proposal.

Key Achievements Post-EneGaeru Biz Implementation


The integration of EneGaeru Biz not only solved these issues but also produced significant benefits:

1. Reduced Lead Time: The lead time for proposals was dramatically shortened from 1-1.5 months to just one week. By establishing a dual-phase proposal method, involving rapid initial proposals via custom spreadsheets followed by detailed offerings using demand data obtained through EneGaeru Biz, the stagnation in proposals was effectively eliminated.

2. Zero Advertising Cost with High Project Volume: The precision of rapid proposals built trust with partners, leading to 80-90% of projects being referrals from these partners. This arrangement facilitated a structure where partners are responsible for securing appointments, resulting in over 1,000 simulations conducted annually at no advertising expense.

3. High Prediction Accuracy: The simulator has proven prediction accuracy exceeding 95%. After comparing forecasts with actual results across projects operational for over a year, discrepancies remained within ±5%, indicating remarkably high precision. Presenting this data to clients has enhanced the reliability of proposals made to management, thereby improving conversion rates.

4. Empowering New Employees: With the development of operational manuals, newcomers with just two months of experience can effectively manage complex proposals tailored for executives. This has helped the company transition away from a dependence on individual expertise, ensuring consistent quality in proposals.

A Testimonial from Kyoshin Koken's Executive Director


Mr. Ichikawa, Executive Director at Kyoshin Koken, expressed, "EneGaeru Biz has enabled us to conduct accurate simulations swiftly in-house. To support our partners in securing orders, being able to simulate on-site is crucial. Moving forward, we aim to raise broader awareness of sound forecasting in the market, thus increasing the number of businesses where the advantages of solar power adoption can be realized."
