ティ・エス・アイ Company Profile

We support our customers' businesses with proposal-based consulting centered on a customer-oriented service approach.

Our company was established as a subsidiary when the information systems department of a construction company became independent in April 1993. Furthermore, since January 2000, we have been operating as an independent software house to expand our business significantly. We are particularly focused on providing system support for the construction industry and offering original PC software that is immediately useful for practical operations, such as the "Construction Cost Management and Accounting System" and the "Site Cost Management System," along with educational services. Aiming for the full-scale informatization of small and medium-sized construction businesses, especially the realization of CALS/EC, we are actively engaged in sales activities in the metropolitan area, Chukyo, and the Keihanshin region, centered around proposal-based consulting with a fundamental stance of "user-oriented service."
