University of Illinois customers (non-students) can pay invoices via the GAR Online Payment Center.
Customers can pay invoices from campus departments online using an electronic check (e-check) or, in some cases, a credit card (Visa, MasterCard, Discover, American Express). This payment center is often used by non-students living in campus housing to pay their rent.
Users whose account number is entirely numeric will log into the system with their Enterprise ID. Account numbers that begin with "@" will log in with a unique set of GAR credentials, which are obtained through separate enrollment. For additional support, contact firstname.lastname@example.org or user documentation (PDF) on the OBFS website.
