Equipped with tens of thousands of electrical material data. Automating everything from material selection to the calculation of composite unit prices, we achieve a departure from rough estimates and ensure profit security.

The most challenging aspect of creating estimates for electrical work is likely the identification of a vast array of materials such as cables, switches, and outlets, as well as the calculation of "composite unit prices" that include labor costs. In today's world, where material prices fluctuate dramatically, manual management using Excel has reached its limits. "Koujiya-san," which specializes in electrical equipment construction, comes standard with data on electrical materials from major manufacturers. With just one click, you can access the latest unit prices and smoothly create complex hierarchical estimates. Calculations that separate "materials and labor" or combine them into composite unit prices can be done freely. By achieving standardization that ensures "the same amount regardless of who creates it," we dramatically shorten the time needed for estimate creation. Why not focus on sales activities to secure more projects or on-site management with the time saved? We invite you to experience the capabilities of the estimating software chosen by professionals in electrical work.
