System Consulting & Integration

What System Consulting & Integration does

System Consulting & Integration (SCI / 株式会社 エス・シー・アイ) is a privately held Fukuoka-based IT services firm founded in January 1990. The company operates three integrated lines: (1) custom System Solutions — design, development, and maintenance of production management, inspection, inventory, logistics, and ERP-integration systems for manufacturing and distribution clients, built on Java, .NET, VB.NET, C#, Vue.js, React, PHP, and ASP.NET against SQL Server, Oracle, and PostgreSQL databases; (2) IT Service / Consulting — strategic and operational consulting plus technical support for packaging, mail order, seafood processing, uniform rental, and automotive sectors; and (3) the proprietary Yes! 人事 software product — a patent-protected (Patent No. 4602813) point-based retirement pension management system sold in three tiers (Light ≤70 employees, Executive 70–1,000, Excellent 1,000+) plus a Model Design simulation add-on, with annual maintenance contracts.

The business model combines one-time professional-services fees for custom development and consulting, perpetual software licensing for Yes! 人事 with subscription-based annual maintenance, and a small-volume customization services line that aligns the product with each client's retirement regulations. Go-to-market is direct enterprise field sales: website-driven inbound inquiries, on-site demonstrations in regional cities (e.g., Miyazaki, Nagoya, Sendai), and customization design engagement. Customer relationships include long-tenured Yes! 人事 deployments (e.g., Minami-Kyushu Mazda since October 2005, Alpen since June 2008) alongside service-only relationships with major corporates such as Fujitsu and Asahi Kasei.

SCI is small (1–10 employees) but operationally mature: 35+ years of continuous operation, ¥40 million registered capital, headquarters in Hakata-ku, Fukuoka, an established work-life balance culture (125 annual leave days, no overtime after 19:00), and a related-company affiliation with Soft Service Co., Ltd. The company is led by Representative Director Daifu Ryuichi (大寶 竜一) and holds membership in the Fukuoka Information Service Industry Association.
