What Sigma Soft Service does

Sigma Soft Service Co., Ltd. (シグマソフトサービス株式会社) is a privately held Japanese IT services company founded in January 1990 and headquartered in Nihonbashi, Tokyo. The company operates under a 'One-Stop Solution' model spanning four integrated service lines: System Introduction Services (consulting, kitting, nationwide deployment of POS, network, and enterprise hardware), System Maintenance and BPO Services (24/7/365 helpdesk, field support, send-back repair, continuous improvement), Staffing Services (dispatch of IT engineers, helpdesk staff, and field technicians under labor dispatch permit 派13-306897), and A-Zen, a custom sheet metal manufacturing service launched in 2022 that produces bespoke store fixtures and equipment enclosures for retail and food service clients. The company's delivery model is asset-light, leveraging a nationwide service partner network of contractors and engineers combined with self-operated kitting centers in Saitama, Tokyo (Hachioji, Koto), and Osaka (Suita, Osaka city).

The firm serves a concentrated enterprise base in Japanese retail, food service, and manufacturing verticals, with named-reference deployment scales including approximately 4,000 convenience store kiosks, 2,000 supermarket POS units under regular maintenance, 2,600 insurance branch PCs, and 500 factory-floor PCs for a pharmaceutical manufacturer. The company holds Privacy Mark certification (registration 22000282(04)), JIS Q 15001 compliance, Security Action self-declaration, and Hospitality Promotion certification; its co-developed Emuktion Monitor Rack with M Corporation was formally adopted into the partner's product line in early 2025.

Revenue is generated through a mix of project-priced system integration engagements, recurring SLA-based managed services and BPO contracts (annual billing), monthly personnel dispatch at competitive market rates, and per-unit/per-project pricing for A-Zen custom manufacturing. The company reported 31 employees as of October 2024, expanded kitting center capacity by 250% in May 2024, and added NASEF JAPAN partnership and M Corporation co-development agreements in 2025-2026 to extend into the education and digital signage sub-verticals.
