Jonas Construction Software

Jonas Construction Software is an integrated enterprise resource planning platform for general contractors, specialty subcontractors, and service contractors, providing construction-specific accounting, project management, job costing, service management, and payroll in a comprehensive back-office system for mid-size construction businesses. Headquartered in Toronto, Canada, and part of Jonas Software, a division of Constellation Software, Jonas Construction has served the construction industry for more than 30 years and built a customer base among contractors that have outgrown entry-level accounting software but have not adopted the cloud-native project management platforms that newer vendors provide. The system's depth in construction accounting, certified payroll, and union payroll management makes it a practical choice for complex union and prevailing wage construction environments.\n\nJonas Construction's integrated suite covers the complete construction business workflow including job cost accounting with real-time budget tracking, accounts payable and receivable, certified payroll and union reporting, subcontract management with lien waiver tracking, purchase orders, equipment management, project management with document control, and a service dispatch and work order management module for companies with service operations alongside construction. The integrated architecture means that job cost data, payroll, and project information share a common database, eliminating reconciliation between separate systems.\n\nJonas competes with Sage 300 Construction and Real Estate (Timberline), Viewpoint Vista (Trimble), Foundation Software, and Acumatica Construction in the mid-market construction ERP space. Its comprehensive integrated suite and deep payroll capabilities position it for contractors with 20 to 300 employees that need full back-office integration, particularly in sectors with union and certified payroll requirements. As part of Constellation Software, Jonas benefits from operational stability and ongoing product investment without the pressure of venture-driven growth requirements.
