Accounts receivable

ARBI stands for accounts, receivable, billing and invoicing, and refers to the accounts receivable module used in PeopleSoft. ARBI is used by campus departments to create invoices, which are then posted to their financial statements and mailed. Our office assists with monitoring, aging and reconciling receivables as well as the collection of payments. This section describes how the accounts receivable process works at the University, how to locate ARBI customers and how to process invoices.


Our campus is proud to offer training for all aspects of the ARBI process. Classes are offered on a wide range of topics and available both online and in-person. For information on ARBI training, please refer to our ARBI training section.

When should I use ARBI?

ARBI is used for invoicing individuals and entities that exist outside of the University. ARBI is not intended for student billing, inter-departmental or inter-campus billing.

Why use ARBI?

  • Revenue is posted to your financial statements when the invoice is created.  The invoice is documented in PeopleSoft.
  • Administration is performed by our office – We will collect and process payments, make sure everything has posted correctly, send past due notices, age and reconcile receivables.
  • Customers can pay by credit card (Visa, MC, Discover and American Express) with no fee to them or to your department
  • Departments do not have to process or deposit payments (unless they prefer to).  There is a payment coupon with instructions as part of the invoice created.
  • Accounting Services will notify the billing department and send past due notices.
  • Invoices which are not paid can be sent to the University’s collection agency if deemed appropriate by the billing department.
  • No cost for postage, printing, mailing or accounting services to the billing department.
