Sage 100 Contractor

Sage 100 Contractor is a construction-specific accounting and project management platform built for small to mid-size specialty contractors and general contractors. Originally developed as Master Builder Software (founded ~1980 by Dan Smith), acquired by Intuit in 2001, then by Sage Software in 2006, and rebranded Sage 100 Contractor. The platform integrates job cost accounting, construction payroll (including union and certified payroll), estimating, project management, service dispatch, scheduling, and document control in a single system. It supports both on-premise and cloud-hosted deployment and is used by approximately 18,000+ contractor businesses across the US.
