For over 40 years, SDSI has designed and developed specialized desktop software for contractors, engineers, and service companies who couldn’t find the right tool on the market.
We learn your current workflows, pain points, and goals before writing a single line of code.
We prototype in real Windows environments so you see exactly how it will feel to use.
Clean, maintainable code with comprehensive documentation and training for your staff.
We don’t disappear after launch. Most of our custom projects evolve with the client for many years.
We specialize in practical, high-value tools that integrate tightly with Rapid Estimator or stand alone.
Real-time job cost tracking that pulls directly from your estimates and syncs with your accounting system. Daily production reporting for field teams.
Highly specialized calculators for niches like fire protection, curtain wall, precast, or complex mechanical systems that generic software can’t handle.
Windows tablet and desktop tools for daily logs, T&M tracking, material receiving, and punch lists with offline capability and seamless sync.
We frequently rebuild or extend 15- to 25-year-old internal applications into modern, supportable Windows desktop experiences.
We would be happy to discuss your project. Most custom engagements begin with a no-obligation discovery call.
