Sage 300 CRE API
Sage 300 Construction and Real Estate has no public REST API — only a legacy SOAP/COM layer for certified Sage partners. Integuru can generate a production-ready HTTP API — chat with us to get started.
Overview
Sage 300 Construction and Real Estate is the financial backbone for a large segment of mid-size and enterprise general contractors, subcontractors, and real estate developers in North America. It covers job cost accounting, project management, subcontractor management, accounts payable, payroll, and equipment tracking. Construction finance teams that manage project-level profitability, subcontractor payment schedules, and cost-to-complete forecasting often do so entirely within Sage 300 CRE. For construction tech platforms, lenders, and surety bond companies that need programmatic access to job cost data, Sage 300 CRE is one of the most common systems of record — and one of the most difficult to connect to.
Sage 300 CRE has no public REST API. What Sage does expose is a legacy SOAP/COM-based integration layer called the Sage 300 CRE Open APIs, designed for certified Sage implementation partners using Windows-native development tooling. This is not a modern developer experience: it requires a Sage partner agreement, COM-compatible tooling, and deep knowledge of the legacy SDK. Development teams building construction tech products, data pipelines, or financial reporting tools have no self-serve path to Sage 300 CRE data, and the COM layer is not a realistic option for a team building a web-based product or a cloud-native integration.
Integuru generates a production-ready HTTP API for Sage 300 CRE by working at the web application layer, using the same authenticated HTTP requests the Sage 300 CRE browser interface sends when a project accountant pulls a job cost report or reviews a subcontractor payment. No Sage partner agreement, no COM tooling, and no legacy SDK knowledge is required. The Production plan includes 24/7 on-call maintenance so session changes and web application updates are handled before they disrupt your calls.
The web application layer. The Sage 300 CRE Open APIs and the Sage 300 CRE browser-based web application are entirely separate surfaces. Integuru works at the web application layer, using the same HTTP requests the browser sends when a construction accountant navigates job cost or subcontractor records. This is how every Sage 300 CRE user accesses their data today — Integuru maps those requests into a documented API.
Why Teams Need This Integration
The complete absence of a REST API creates hard blocks for every team that needs Sage 300 CRE data programmatically.
Construction ERP connectors and data synchronization platforms. Platforms that synchronize financial data between Sage 300 CRE and project management tools, BIM systems, or owner reporting portals cannot operate without a structured data feed from Sage. list_projects and get_project_detail provide the job roster; get_job_cost_summary and list_budget_line_items provide the financial picture at cost-code level. Without Integuru, these connections require manual exports from Sage on a schedule that no finance team reliably maintains.
Lender and surety bond platforms. Construction lenders and surety companies that underwrite bonds against a contractor's job portfolio need current cost-to-complete figures, subcontractor payment status, and change order exposure. get_job_cost_summary returns revised budget, committed costs, and cost to complete for each job. list_subcontractors and list_change_orders add subcontract exposure and change order risk to the financial picture. Pulling this from Sage 300 CRE currently requires either manual export by the contractor's accounting team or on-site access to the Sage instance — neither scales to a portfolio of dozens of contractors.
Subcontractor payment automation platforms. list_subcontractors and get_subcontractor_detail provide subcontract amount, payment history, and retention data per job. Platforms that automate subcontractor pay applications, lien waiver collection, or payment approvals need this data structured and accessible on a recurring basis. The absence of any API means these platforms currently rely on manual data entry from the contractor's Sage exports.
Change order management and claims tools. list_change_orders surfaces approved and pending change orders with amounts and approval dates for each job. AI-powered change order analysis tools, contract compliance platforms, and claims preparation products need structured change order history to identify cost growth patterns and risk exposure across a contractor's portfolio.
Construction finance and job cost reporting. Finance teams and CFOs at construction companies often need job cost reporting in tools outside Sage 300 CRE — Power BI dashboards, custom reporting portals, or board-level financial views. Integuru provides the data feed that makes this reporting live and automated rather than dependent on monthly manual exports.
Construction Workflows This Integration Covers
The seven planned actions cover the core financial and project management data that Sage 300 CRE holds:
- Job management:
list_projectsandget_project_detailsurface the active job roster with contract value, project manager, start date, and completion percentage. These anchor every downstream financial workflow. - Job cost financials:
get_job_cost_summaryreturns the financial state of a job including original budget, approved changes, revised budget, committed costs, and cost to complete — the core figures for lender reporting, surety underwriting, and executive dashboards.list_budget_line_itemsadds cost-code-level detail for granular budget tracking. - Subcontractor management:
list_subcontractorsandget_subcontractor_detailcover the subcontract record per job including trade, subcontract amount, retention, and payment history. These feed payment automation platforms, lien waiver tools, and subcontractor compliance monitoring. - Change order tracking:
list_change_ordersprovides change order history with status, amounts, and approval dates for risk analysis, claims preparation, and cost growth monitoring across the job portfolio.
Adjacent Integrations
Integuru already operates in adjacent field services and workforce verticals. The Cilio integration covers 7 live actions for work order management, dispatch, technician scheduling, and availability in the field services context — the session management and authentication patterns that Sage 300 CRE's web application represents are directly analogous. The HomeBase integration provides 5 live actions for employee records, timesheets, and wage data, applicable to construction payroll verification and workforce cost allocation against job codes. The IME integration covers live work order estimating, demonstrating that cost entry and financial workflow integrations in field operations already run in production on Integuru today.
What Sage 300 CRE currently offers publicly
Sage 300 Construction and Real Estate has no public REST API. The platform exposes data through a legacy SOAP/COM-based integration layer called Sage 300 CRE Open APIs, intended for certified Sage development partners running Windows-native tooling. There is no modern REST or JSON API available to development teams, no developer sandbox, and no self-serve programmatic access path. Teams that need to read job cost data, subcontractor records, or budget figures must do so manually through the Sage 300 CRE interface or through a certified Sage implementation partner.
Sage 300 CRE official siteActions Integuru could expose
Return a paginated list of active and completed jobs with job number, description, contract amount, and current status
Retrieve the full job record including owner, contract value, project manager, start date, and completion percentage
Return the cost summary for a job including original budget, approved changes, revised budget, committed costs, and cost to complete
List budget line items for a job with cost code, category, original budget, change orders, and cost to date
Return subcontractor records linked to a job with vendor name, trade, subcontract amount, and payment status
Retrieve the full subcontractor record for a job including contract terms, retention amount, and payment history
List change orders for a job with number, description, status, amount, and approval date
These actions reflect what Integuru would generate based on the workflows Sage 300 CRE exposes through its web interface. Final scope is confirmed when the integration is built.
