Accounting Representatives

Every Olin department has an Olin Accounting Representative who can advise you on processing department documents including Check Requests, Vendor Invoices, Purchase Orders, Reimbursements, Travel Advances and Travel Expense Statements.

Accounting Information System

The Washington University Accounting Information System (AIS) is a password protected online tool for ordering supplies from online catalogs and approving expenditures. Access to AIS requires Department Manager approval and training.


Washington University operates on a fiscal year from July 1 to June 30. Olin’s Accounting Department provides data and support to departments throughout the budgeting process.

Accounts Payable

Your Accounting Representative can advise you on the appropriate process for paying department invoices and reimbursements.  These processes include Check Requests, Purchase Orders, Inter Department Invoices (IDs), Travel Advances and Travel Expense Statements.


Washington University has strict policies that govern the purchasing process.  The Purchasing Department website offers a list of preferred vendors as well as online resources that facilitate making purchases.  For more information, please refer to the Washington University Purchasing website

Tracking Expenses

In order to maintain the integrity of various funding sources, account numbers are used to systematically classify accounts into an identifiable and logical order. For instance, funds or special report (SR) codes may be used to categorize or track different types of expenses.
