Rational Consulting Co., Ltd. is a Bangkok, Thailand-based software consultancy, headquartered at MS Siam Tower on Rama 3 Road. Its own site describes itself as a software consulting firm covering ERP, web development and mobile development, and states it has operated for "over 10 years," though no specific founding year is given.
The firm's Infor practice centers on Infor CloudSuite Industrial (CSI), Infor Warehouse Management System (WMS), and Infor Operating Services (OS), which lines up with its Infor Partner Network product listing (SyteLine/CloudSuite Industrial, WMS & Supply Chain, and OS & ION). Beyond ERP implementation, the company also offers web and mobile application development, digital-transformation business consulting, warehouse management solutions, and cloud-based enterprise systems.
The site's customer-reference section groups clients by industry, spanning automotive, aerospace, electronics, process manufacturing and trading sectors, but does not name any specific client companies in the text reviewed; only unlabeled logos and industry categories are shown, so no notable clients are recorded here.
