Development of a Unified Estimation and Contracting Software System for Custom Construction Projects

The client relies on multiple spreadsheets and specialized knowledge for creating custom home estimates, leading to time-consuming manual rework, errors, and bottlenecks. Price volatility and customizable options require frequent updates, which are difficult to manage efficiently, resulting in delays and reduced capacity to serve clients effectively. Sales teams are unable to generate independent estimates quickly, harming customer experience and scaling potential.

A medium-sized custom home builder specializing in high-end, customizable residential projects, seeking to streamline their estimating and contracting workflows to increase efficiency and scalability.

• Reduce time to generate accurate estimates and contracts from potentially several hours to under one hour.
• Develop a scalable, flexible software system that integrates multiple customization options with real-time pricing updates.
• Enable non-technical staff, such as sales personnel, to independently produce and modify estimates and agreements without developer intervention.
• Minimize data entry errors and improve consistency by automating data transfer and validation processes.
• Allow administrators to easily update pricing, options, and other variables in response to market fluctuations without requiring complex reprogramming.
• Create a unified platform that replaces multiple spreadsheets and manual workflows, enhancing collaboration among sales, estimating, and contracting teams.

• Unified, formula-based estimation engine capable of handling multiple customizable options for home designs.
