What ChangeGuard does
Systematic review, every time.
The same rigorous analysis your project manager would do — if they had unlimited time and never missed a step.
Markup Rate Verification
Extracts and calculates actual labor, material, equipment, overhead, and profit markups from invoices and cost sheets — compared against your contract allowances.
Entitlement Screening
Cross-references each change against your baseline contract to assess whether the claimed scope was actually excluded from your original price.
Cross-Change Intelligence
Detects repeated mobilization charges, previously-paid scope, and fragmentation patterns across your full change register — not just the current submission.
The process
From submission to findings in minutes.
Upload the change order package
Submit the contractor's submission — cost breakdown, backup documentation, and your baseline contract.
ChangeGuard reviews it
The system extracts markups, screens entitlement, checks contract terms, and compares to your change history.
