Simple System Co., Ltd.(シンプルシステム株式会社) is a DX consulting and enterprise software services company based in Yamaguchi Prefecture, Japan. It serves small and midsize businesses with strategic DX consulting, business automation, data-driven operational improvement, and web system development. The company also operates the DX Management Game, the simpleRec facial-recognition entry/exit management system, and several AI diagnosis/content subscription services. Its core positioning is not simply “building systems,” but designing practical digital mechanisms around real business challenges.
On the consulting side, Simple System covers business issue and workflow diagnosis, DX roadmaps, tool selection, custom system development, and automation implementation using RPA, GAS, API integrations, and related methods. For data-driven improvement, it emphasizes integrating e-commerce data, financial information, and customer data, including Amazon EC optimization, cash-flow analysis, financial visualization dashboards, and support for subsidies/financing. On the product side, the DX Management Game runs in the browser and supports multiple participants, team battles, AI recommendations, and real-time reports for organizers, making it suitable for training and workshops. simpleRec is a cloud-based facial-recognition entry/exit management system that supports multiple sites, multiple cameras, and viewing from multiple terminals.
Consulting fees are not published in a standardized way; quotes depend on the scope, scale, and duration of support. Engagement formats include one-off consulting, monthly advisory contracts, and project-based contracts, with a free consultation as the entry point. Disclosed pricing includes “1人CTO開発記録” at 980 JPY per month and the entrepreneurship diagnosis at 1,000 JPY with a one-month refund guarantee. The DX・AI diagnosis is completely free, and the SME Management Consultant matching service is free for companies. Pricing packages, seats, device fees, or usage-based billing for the DX Management Game and simpleRec have not been disclosed.
The main advantages are its focus on small and midsize businesses, its emphasis on starting small, and its integrated support from business strategy through implementation, delivered by a team with backgrounds in SME management consulting, information processing technology, and information security management. The company also operates its own EC, FC, finance, and AI platforms, giving it practical environments for validation. The weaknesses are the lack of key enterprise SaaS information: for simpleRec, details such as SLA, permission model, data retention, encryption, compliance certifications, public APIs, and payment methods are not disclosed. Third-party integrations are also described only broadly as RPA/GAS/API.
It is best suited to Japan-based small and midsize businesses, e-commerce operators, multi-location/FC organizations, and companies, universities, or groups that want to run DX training through gamification. Users in mainland China should note that website accessibility, Chinese-language support, cross-border payments, contracts, and personal information compliance are not explained. Based on the available text, access status can only be rated as unknown. For similar needs in China, it would be sensible to first evaluate DingTalk, WeCom, Feishu, Mingdao Cloud, Jiandaoyun, and local access-control/visitor-management vendors.
