MFA New Supplier Registration

We utilize PaymentWorks to onboard all new domestic suppliers. Please work with your department contact or email iSupplyGW [at] gwu.edu (iSupplyGW[at]gwu[dot]edu) to be sent an invitation to register. Our iSupplyGW Supplier Registration Handbook provides detailed information on the steps for registering.

The University utilizes a procurement card or a Single Use Account (SUA) as our primary method of payment, at its sole discretion, for purchase order and payment transactions. Suppliers shall accept these expedited methods of payment upon the request of the University, and will do so at no additional charge to the University.
