Accounts Payable

The Accounts Payable Department is responsible for processing Correction Requests, IOTDs, ICDs, POs, Travel, Business Procurement Card Program and Vendor Maintenance requests.  Documents that come in for review and processing are handled based on a "first-in, first-out" basis.  We process hundreds of requests each week, and strive to process each document as quickly as possible.  Chrome River - Invoice is now LIVE!!!


The following resources have been assembled to assist end users with routine accounts payable processes. Additional information can be viewed by clicking on the plus sign in each section.

Account Code Guide - For ICDs

Use the guide to locate the appropriate account code for the good or service purchased. The guide is broken into three primary expenditure classifications: contractual services, commodities and capital outlay.  Within each classification is a detailed description used to code purchases accurately.

Chrome River - Invoice

Chrome River is WSU's new comprehensive Invoice system.  Departments can now begin entering direct pay invoices into Chrome River instead of using the paper ICD process.

All payments associated with a WSU purchase order will continue to be processed utilizing the paper ICD process.  This includes both partial and full payment against a purchase order.

The IOTD process for paying other WSU departments has not changed and will continue to be handled outside of the Chrome River system.

The quick reference guides below are designed to give a brief explanation on each topic with reference pictures to aid you in completing the invoice in Chrome River.
