Sage 300 Construction and Real Estate API
Sage 300 Construction and Real Estate (formerly Timberline) REST and OData API for construction and real estate accounting, job costing, and project management. Enables AI agents to manage job cost tracking and budget variance analysis for construction financial management, handle certified payroll and Davis-Bacon prevailing wage for construction compliance automation, access accounts payable and subcontractor payment processing for construction cash flow, retrieve WIP (Work in Progress) schedule and overbilling/underbilling analysis for project accounting, manage general ledger and financial reporting for construction company financials, handle AIA billing and Schedule of Values for owner billing automation, access equipment cost tracking for construction asset management, retrieve real estate portfolio and lease management for property financial reporting, manage subcontractor compliance and lien waiver tracking for construction risk management, and integrate Sage 300 CRE with Procore, project management, and HR platforms.

Best When
A general contractor, specialty contractor, construction company, or real estate developer using Sage 300 CRE wanting AI agents to automate job costing, certified payroll, AIA billing, WIP analysis, and construction financial reporting.
Avoid When
DAVIS-BACON PREVAILING WAGE: Automated certified payroll must apply current DOL wage determination rates by trade classification, county, and project type; incorrect rates create DOL back-pay liability and federal contract debarment. AIA billing accuracy — automated AIA G702/G703 completion percentages must reflect actual work-in-place verified by project manager or owner's rep; automated overbilling creates owner disputes and potential contractor fraud liability. Lien waiver management — automated subcontractor payment must include conditional lien waiver exchange before payment release; payment without lien waiver creates mechanics lien on project property. OData query complexity — Sage 300 CRE OData API supports complex queries but large dataset extraction without proper filtering can cause timeout and memory issues in automated workflows.
Use Cases
- • Tracking job costs from construction accounting agents
- • Processing certified payroll from compliance agents
- • Managing AIA billing from project billing agents
- • Analyzing WIP schedule from financial reporting agents
Not For
- • Non-construction or non-real-estate businesses
- • Simple bookkeeping without job costing requirements
- • Technology or service firms without construction operations

Known Gotchas
- ⚠ DAVIS-BACON WAGE RATE CURRENCY: Automated certified payroll must pull current DOL wage determination rates from WD.gov before each payroll run; hardcoded rates become stale and create DOL compliance liability; implement wage rate refresh before every automated certified payroll cycle
- ⚠ OData query timeout risk — Sage 300 CRE OData API with large job cost datasets and complex joins can timeout in automated extraction; always apply date range filters and project-specific filters; avoid unbounded OData queries on job cost tables
- ⚠ AIA percentage complete verification — automated G702/G703 completion percentages must match owner-approved stored material and work-in-place; automated completion percentage without owner concurrence creates billing dispute and retainage risk
- ⚠ No webhooks — AP approval workflow, payroll posting, and job cost update events require polling; no push notification for construction accounting event triggers
- ⚠ Module licensing controls API access — Sage 300 CRE API access is gated by licensed modules; automated workflows accessing payroll or real estate endpoints without corresponding module license return permission errors; verify module entitlements before building workflows
- ⚠ Lien waiver prerequisite — automated subcontractor payment release must retrieve signed conditional lien waiver; Sage 300 CRE does not enforce lien waiver exchange in API; implement lien waiver gate in automated AP workflow
