Best When
A general contractor, specialty contractor, or construction company using Foundation Software wanting AI agents to automate job costing, certified payroll, AP processing, WIP schedule, AIA billing, and construction financial reporting.
Avoid When
DAVIS-BACON PREVAILING WAGE COMPLIANCE: Automated certified payroll for public works must apply correct Davis-Bacon or state prevailing wage rates by classification and jurisdiction; automated payroll with incorrect wage rates creates DOL back-pay liability and contract debarment risk. Union fringe benefit accuracy — automated union payroll must correctly calculate and remit union health, pension, and annuity fringe benefits per applicable CBA; automated fringe miscalculation creates union trust fund audit and ERISA liability. AIA billing accuracy — automated AIA G702/G703 Application for Payment must accurately represent completed work percentages; automated overbilling creates contract dispute and construction lien exposure. Lien waiver management — automated subcontractor payment must include conditional lien waiver exchange; automated payment without lien waiver creates mechanics lien on project property.
Use Cases
- • Tracking job costs from construction accounting agents
- • Processing certified payroll from compliance agents
- • Managing subcontractor payments from AP agents
- • Generating AIA billing from project billing agents
Not For
- • Non-construction businesses without job costing
- • Simple bookkeeping without construction-specific features
- • Technology or service firms without construction payroll

Known Gotchas
- ⚠ DAVIS-BACON WAGE RATE ACCURACY: Automated certified payroll must apply current DOL wage determination rates by trade classification and county; incorrect rates create DOL back-pay liability and federal contract debarment; update wage rates from DOL WD.gov before each automated payroll run
- ⚠ Union fringe benefit remittance — automated union payroll fringe calculation must match collective bargaining agreement (CBA) fringe schedules exactly; automated fringe underpayment creates union trust fund delinquency and ERISA violation
- ⚠ No webhooks — Foundation Software lacks webhook support; AP approval completion and payroll events require polling; implement scheduled polling for event-driven construction accounting workflows
- ⚠ AIA percentage complete accuracy — automated AIA G702/G703 completion percentage must reflect actual work-in-place verified by project manager; automated overbilling creates owner disputes and potential contractor fraud liability
- ⚠ Lien waiver prerequisite for payment — automated subcontractor payment workflow must require conditional lien waiver before payment release; automated payment without lien waiver creates property lien exposure
- ⚠ Certified payroll state compliance — certified payroll requirements vary by state (Federal Davis-Bacon, state prevailing wage, and Little Davis-Bacon acts); automated certified payroll must apply correct state-specific requirements per project location
