Vendors
The Comptroller's Business Office is located at College Place Uptown, 100 S. Fell Ave, Suite F, Room 238. Our office handles the creation of, updates to, and management of vendor records that Illinois State University uses for Purchasing and Accounts Payable activities. We ensure that every company or individual that is paid has an accurate, complete and approved vendor record in the system.
It is critical because it ensures payments are directed to the correct vendor and address, supports 1099 tax reporting compliance, prevents duplication of vendors, protects against fraud or unauthorized payments, and keep our AP processes running smoothly.
Maintained information typically includes:
- Vendor Identification: Name/ID/Status
- Addresses: (Mailing/Ordering/Remittance)
- Payment Details: Check or ACH
- Tax Information: Taxpayer ID (TIN), 1099 Eligibility and Reporting Flags
- Contact Info: Names, Email Address, Phone Numbers
- Institutional Controls: Use Restrictions, Approval Status, Notes/Comments for Internal Users
