The short version
Most people in North American construction accounting still call it Timberline. Sage 300 Construction and Real Estate combines job cost accounting, payroll, billing, and procurement with property management functionality for owners and developers, and it carries one of the larger installed bases in the industry. The product is sold and supported today. It also represents the on-premises generation of Sage's construction portfolio, and that single fact shapes almost every buying decision around it.
Where Sage 300 CRE comes from
Timberline Software was founded in Oregon in 1971 and spent three decades as a fixture of US construction accounting. Sage acquired it in 2003 through its US subsidiary, marketed it as Sage Timberline Office, and renamed it Sage 300 Construction and Real Estate in 2012. The name invites a second confusion worth heading off: this has nothing to do with the Sage 300 mid-market ERP, which descends from Accpac.
Maintenance continues. Version 26.1 shipped in 2026, payroll tax updates keep arriving, and current Windows Server releases are supported. Sage has announced no end-of-life date, while positioning the cloud-native Sage Intacct Construction as the strategic successor and promoting migration tooling for 300 CRE customers.
Functional scope
Financials run general ledger, accounts payable and receivable, cash management, and job costing, with contract billing that includes AIA-style payment applications. Payroll processes United States and Canadian requirements, certified payroll among them, plus union rules. Project management, procurement, inventory, equipment cost, and service management extend the operational side. The genuinely distinctive piece is property management: leases, tenants, and portfolios, which lets a developer run construction and real estate operations out of one system. Sage Estimating integrates natively. Reporting leans on built-in inquiries plus Office- and ODBC-based tools.
Buyers, deployment, and cost
Customers are general contractors, specialty trade contractors, home builders, real estate developers, and property owners or managers across the United States and Canada. Firms that both build and operate real estate get the most out of the combination. Payroll, tax, and billing conventions are North America specific.
The application is Windows client-server, on-premises, built on an older database layer. Hosting partners can run it in private cloud environments; a browser-based SaaS product it is not. Sales and implementation go through Sage-certified consultants, and Sage publishes no pricing, so any budget starts with a partner quote. Weighing continued on-premises operation against a move to a cloud product is easier with an explicit cost model such as our ERP TCO calculator.
Our take
Nothing else in the Sage lineup matches this depth in combined construction and property accounting, refined over decades and backed by an experienced reseller channel. For a firm that builds and then operates the same portfolio, that combination still carries real value. Equally plain is the generational problem: client-server architecture, an aging database layer, and a vendor whose modernization investment sits with Sage Intacct Construction. A contractor buying a first construction system today should not start here, and should compare the cloud-native options honestly before committing. Existing customers are under no announced deadline, and the version 26 releases show that maintenance is real, but scope the eventual data migration early: decades of job and property history rarely move without pain.
