Overview
Jonas Construction Software is an all-in-one construction ERP and accounting platform built for mechanical, HVAC, electrical, plumbing, and other specialty and service contractors. Rather than bolting onto a third-party ERP, Jonas is itself the system of record: it combines general ledger, accounts payable/receivable, payroll, and job costing with project management and service management in a single database, so field and back-office teams work from the same real-time data.
The platform is organized around four pillars: accounting, project management, service management, and operations/reporting. On the accounting side it handles multi-company general ledger, AP/AR, U.S. and Canadian payroll (posted directly to job cost and GL), bank reconciliation, and work-in-progress (WIP) reporting built for construction financial workflows. On the project side it covers change orders, RFIs, submittals and transmittals, project scheduling, daily logs, document management, and drawing control. Service-oriented contractors also get work order management, dispatch scheduling, preventative maintenance contracts, and a client service portal.
Jonas reports more than 30 years in the construction software market and over 14,000 users, and vendor marketing describes more than 50 integrated modules across the suite. The company is headquartered in Markham, Ontario, Canada.

- Deep focus on mechanical, HVAC, electrical, plumbing, and specialty service contractors rather than general-purpose construction accounting
- Combines project-based construction management with recurring service/dispatch management in one platform
- Long incumbency in the trade-contractor market with a large existing user base (30+ years, 14,000+ users claimed by vendor)
