How to fix: Project ID mismatch.

What happened?

The project number or ID in your payroll doesn't match the registered project on the portal. This happens when using the wrong contract number, project code, or when data crosses between different public works projects.

The Zero-Tolerance Solution

XMLExpress's Project Registry links every payroll to the correct project automatically, preventing cross-project ID mismatches. Select the project once, and every subsequent report uses the correct ID.

Stop Fighting Government Portals

Contractors spend an average of 4-6 hours per week manually fixing certified payroll errors. With XMLExpress, you can eliminate this bottleneck entirely.

  • Automatic mapping for any CSV format
  • Instant validation against the latest WH-347 XSD
