For Penn State Users ONLY

1. Go to leo.psu.edu, click on the PSU Microsoft Login button, and follow the sign in process.  This will create your LEO User Profile.  
2. Click on the LEO Registration icon located on the LEO Landing Page to be directed to the LEO Registration site.  
3. Complete the brief LEO Registration form to request billing account approval; click the Submit button.

Established LEO users (those who already have a User Profile in LEO) can continue to access LEO Registration anytime to request new/additional billing accounts.

Your billing account is a cost collector provided to you by your advisor or administration and will be in the form of a SIMBA Cost Center (10 digit number), SIMBA Internal Order (12 digit number), or for ARL, a SIMBA WBS Element (12 digit number).

(Return to LEO Registration to create as many billing accounts as needed). When you Add a Billing Account, your advisor/supervisor will receive an email to approve or deny your request. After approval, your account will be available in LEO within 1-2 business days.

For assistance, please contact LEOHELP@psu.edu.

All facility usage is tracked by LEO and will be invoiced on a monthly billing cycle that ends on the 24th of each month. Your advisor/supervisor will receive the monthly invoice which will be paid via the University’s direct-bill payment process.

If you are an onsite operator (i.e.: you enter labs and/or operate equipment), you are required to REVIEW AND VALIDATE EACH AND EVERY TRANSACTION THAT YOU GENERATE WITHIN 5 CALENDAR DAYS OF USAGE. Failure to validate your transactions will cause administrative burden on core facility staff and your advisor/supervisor; facility staff may contact you to address repeated failure of this responsibility.

Transactions that are reviewed and deemed incorrect can be contested and corrected via the LEO Contest feature within 5 calendar days of usage.
