To ensure that everyone is prepared for the upcoming switch from our old payroll system and method of clocking-in / clocking-out to our new one, PLEASE READ ALL OF THE FOLLOWING INFORMATION: 

Starting February 12, 2023, the Celayix Team Xpress app is how you MUST clock-in/clock-out to be accounted for on the job and paid correctly. You can download the Team Xpress app from your app store by searching for “Celayix Team Xpress” and downloading the app from the official Celayix developer. If you don’t have a smartphone, please inform your supervisor.

To retrieve your login information for the Celayix Team Xpress app, you will need to access your SEI Team Email (that all active employees have). If you cannot remember your password for your SEI Team Email (or you have never accessed it before), here are the instructions to login:

1. Go to

2. Your email address is your [email protected]
