Sage 300 Construction API
No native web or REST API. Programmatic access runs through the legacy Timberline ODBC driver, read-only across much of the data, or the gated Development Partner Program. There is no developer portal, self-serve key signup, or official SDKs.
Frequently asked questions
Sage 300 Construction scores F on the API Report Card. No native web or REST API. Programmatic access runs through the legacy Timberline ODBC driver, read-only across much of the data, or the gated Development Partner Program. There is no developer portal, self-serve key signup, or official SDKs.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Sage 300 Construction and Real Estate (CRE), formerly Sage Timberline Office, is a construction and real-estate ERP/accounting platform.
Construction, Typically for general/specialty contractors, homebuilders, and real-estate/property owners needing integrated construction accounting and project/property financials. Finance and project teams run job costing, progress/AIA billing, change orders, AP/AR, construction payroll, and property/lease accounting; data flows across tightly linked modules as the back-office system of record.
A long-established, widely deployed construction ERP (the former Timberline) with a large North American install base and strong G2/TrustRadius/ITQlick footprint. Considered a pioneer and feature-rich, though losing ground to modern cloud ERPs.
Yes, Job costs, billings, change orders, AP/AR, construction payroll, and lease/property financials. This is the contractor/owner's core financial system of record.
30+ years old (Timberline lineage). Legacy on-prem architecture that has not kept pace with modern design; slow release cadence; cloud is a bolt-on rather than native.
No built-in web API; integration relies on ODBC driver and middleware. Full module integration requires enrolling in the Development Partner Program. Full sourced list under Sources below.
Common alternatives include Procore, Viewpoint Vista (Trimble), Foundation Software, CMiC, Premier Construction Software. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Sage 300 Construction API and MCP server so AI agents and internal tools can read and write Sage 300 Construction data. See the Sage 300 Construction integration docs at supergood.ai/docs/sage-300-construction-api.
