Stack Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Ryosuke Fukuda; hereinafter "Stack") announces that Nissen Co., Ltd. (Headquarters: Minami-ku, Kyoto; President: Jun Habuchi; hereinafter "Nissen"), which operates catalog and online shopping businesses, has adopted our commerce operation platform "SQ" for the renewal of its core e-commerce platform.
Nissen is one of Japan's leading retailers. Through this initiative, Nissen will migrate its core e-commerce site, "Nissen Online," from its existing e-commerce system infrastructure to Shopify's enterprise-level commerce platform. In this migration and post-migration operations, "SQ" will play a role in integrally managing a wide range of business areas, including orders, inventory, logistics, customer data, sales promotion, and analysis.
■ Background of Adoption
Nissen initially planned a complete rebuild of its core e-commerce system with a full-scratch approach but revised its policy after considering execution risks, costs, and operational burdens, ultimately deciding to adopt Shopify.
In line with this, "SQ" was adopted as the operational foundation to support Nissen's unique hybrid sales model spanning e-commerce, catalogs, and call centers, as well as Japan-specific business requirements such as subscription services, proprietary payment methods, post-payment options, and complex shipping settings.
■ Role of "SQ"
"SQ" will act as a bridge between various sales channels centered on Shopify and Nissen's long-established internal systems, connecting them smoothly. This will support the construction of a flexible and robust system architecture that can withstand future business growth and changes in business requirements while maintaining stability.
■ About Stack Inc.
Stack Inc. primarily provides the commerce operation platform "SQ," which integrates the main business areas of retail companies. It also offers peripheral solutions for specific needs, such as the Shopify extension apps "Appify" and "VIP," and the lottery sales-focused cart system "FAIR." Currently, it has been introduced to over 250 brands, mainly major apparel companies.
