Form: Interdepartmental Requisition and Invoice
Use of IRI
University personnel that do not have access to the Workday Internal Service Delivery may use the Interdepartmental Requisition and Invoice (IRI) form to requisition supplies and services provided by WSU supplier departments.
Approval to Charge
A department or unit must have prior approval from the Controller’s Office to charge for goods or services. In most cases, a prospective supplier department requests approval by completing a Service Center Application (see BPPM 30.15). A department cannot process IRIs as a supplier department unless a Service Center Application has been submitted and approved.
The IRI serves as an order and billing form.
The IRI is available in PDF format from Policies, Records, and Forms.
Departments may use the IRI to authorize a supplier department to set up a blanket requisition (see BPPM 70.06). This is desirable when the department makes regular purchases from the supplier.
WSU supplier departments may use IRIs to prepare monthly billings for departments who make blanket order purchases (see BPPM 70.06).
