Reunion offers tools to streamline this process, making it more efficient. We recommend that the Sponsor of the project(s) or the EPC/Primary contractor verify the payrolls toward the end of the project, after all data is inputted and any issues are resolved. ### 1. Navigate to the **Payroll Reports** page ![](https://help.reunioninfra.com/hs-fs/hubfs/Screenshot%202025-10-23%20at%203-49-49%E2%80%AFPM-png.png?width=670&height=364&name=Screenshot%202025-10-23%20at%203-49-49%E2%80%AFPM-png.png) ### 2. **Select the Payroll Weeks you want to certify** ![](https://help.reunioninfra.com/hs-fs/hubfs/Screenshot%202025-10-23%20at%203-50-53%E2%80%AFPM-png.png?width=670&height=301&name=Screenshot%202025-10-23%20at%203-50-53%E2%80%AFPM-png.png) ### 3.
