The company provides IT operational efficiency, cloud migration, and digital transformation (DX) support services primarily to small and medium-sized enterprises (SMEs) in Japan, organized into three service pillars: Cloud Services (AWS/Azure implementation, migration, and managed operations with BCP/DR design), DX Support (centered on the Pleasanter low-code platform, Mattermost secure business chat, and the proprietary おしごとゲート suite for IT asset, inventory, and document management, plus CoCo-Cre seat reservation and QueSkA internal surveys), and Custom Development/SES (staff augmentation and commissioned system development, with notable multi-year engagements such as full SCM implementations for manufacturing clients).

The underlying technology stack spans cloud infrastructure (AWS, Azure), the Pleasanter low-code/no-code platform (with both on-premises and cloud deployment), Mattermost business chat (cloud and on-premises, with AI plugin integration), and proprietary SME management applications built on Pleasanter. Recent product extensions include AI capabilities (Claude Code production-deployment service, Mattermost auto-reply, document summarization, and knowledge retrieval bots). Integration breadth covers Microsoft 365, Google Workspace, Jira, GitHub, GitLab, Jenkins, and OneDrive via Mattermost and cloud services.

Kokusai Software operates an exclusively direct, consultative GTM combining enterprise field sales, inside sales via website inquiry forms, free trial offerings for DX tools, downloadable educational content, and exhibition participation (e.g., IT Trend EXPO 2026 Summer). Pricing is quote-driven and not publicly disclosed; revenue streams include managed cloud services, professional services for DX consulting and custom development, and growing recurring support for proprietary product deployments. The company has been consistently profitable over 40+ years and operates entirely within the Kanto region of Japan.
