About Us
Contractors Software Group — A Proven Leader Bringing Technology and Construction Together
J. Knutson & Associates, Inc. www.jknutson.com, our parent company, launched in 1984 as a value‑added reseller of commercial, industrial, and residential construction software. After more than a decade of hands‑on experience working directly with all types of construction companies, we saw a major gap in the market – and Contractors Software Group was born to deliver purpose‑built solutions for residential and light commercial construction companies.
We didn’t just enter the market; we helped shape it.
Our commitment to helping builders and contractors work smarter has driven every innovation we’ve introduced.
Our first major breakthrough, The Plus Series, quickly became the industry’s preferred fully integrated construction management solution. For more than eight years, it helped companies streamline operations, eliminate duplicate data entry, and gain better control over every phase of the building process.
As construction firms demanded greater performance and scalability, we introduced The Professional Series. Powered by a robust SQL-based backend, it delivers the speed, reliability, and data management capabilities growing companies need to manage more projects, more employees, and more complexity with confidence.
Recognizing that many smaller builders were still relying on spreadsheets, manual processes, and disconnected solutions like QuickBooks, we developed The Simple Series. This affordable, easy-to-implement platform gives contractors a clear path to professional construction management software without the cost or complexity of enterprise systems.
When customers asked for greater flexibility, we responded with our Cloud Hosted Series, allowing construction companies to securely access their software anytime, anywhere, for a predictable monthly investment with no costly server infrastructure to maintain.
In 2019, we expanded our ecosystem with CSG Central, a powerful web-based communication portal that connects builders, employees, subcontractors, vendors, and clients through real-time project information. We also launched CSG Central’s Remote Time Card Entry Web App, enabling field crews to submit time directly from the jobsite while automatically syncing with The Professional Series. The result is faster payroll processing, reduced administrative work, improved job costing accuracy, and greater visibility across the organization.
Today, Contractors Software Group is recognized as a leader in construction management technology. Our solutions have received industry-wide recognition, including Constructech’s Top Products Award for The Simple Series and TechHome Builder’s Innovative Housing Technology Award for The Plus Series for four consecutive years.
What truly sets us apart is our ability to provide a complete, fully integrated business management platform for construction companies. From sales, marketing, and customer service to estimating, purchasing, scheduling, job costing, accounting, and real-time communication, every component works together in a single system designed specifically for builders and contractors.
With customers throughout the United States and Canada, our network of certified channel partners provides comprehensive implementation, training, and ongoing support, ensuring every client receives the tools and guidance needed to maximize their success.
As construction continues to evolve, our mission remains unchanged: to deliver innovative technology that helps builders gain control, improve productivity, increase profitability, and build a stronger business.
Whether you’re a small contractor looking to move beyond QuickBooks or a growing builder seeking a fully integrated enterprise solution, Contractors Software Group delivers the software, support, and industry expertise you need to build more efficiently, profitably, and competitively.
