BuyUSI transforms the way goods and services are purchased at The University of Southern Indiana (USI) by providing campus employees with an electronic procurement system that is easy to navigate and intuitive to use, resulting in an easier and faster procurement process. It is the single-entry point where faculty and staff at USI can shop for most of their campus-related purchases. BuyUSI saves money by using negotiated discounted prices from USI. It can track what you purchase and how much you spend on these purchases, improving our ability to negotiate volume discounts.

Use BuyUSI when ANY of the following apply to a purchase:

  1. The payment is $5,000 or more
  2. The item is from a Catalog Vendor (e.g., Amazon)
  3. It is for Chartered Buses, Construction, Contracts/Agreements, Food Catering via Sodexo (Non-Travel), Furniture Items, IT Equipment/Supplies/Software, Medical Equipment/Supplies, Office Supplies, Printing Supplies, or Scientific Equipment/Supplies

Note: If the vendor will not take a Purchase Order (PO), then contact Procurement.

Amazon is a Catalog Vendor in BuyUSI. Therefore, Amazon purchases are to be made in BuyUSI, and the PCard is NOT to be used.

Important: If you use your USI email address for a personal Amazon account, then you MUST set up a second Amazon account using a personal email address BEFORE using the Amazon Catalog in BuyUSI. View the instructions on how to set up a second account.

Do you need a chartered bus for a trip or an event? USI has partnered exclusively with Timi's Tours to meet our chartered bus needs.

  1. Request a quote from Timi's Tours:
  2. Enter a Purchase Order in BuyUSI for Timi's Tours if you decide to use them


Will you also need to enter a Pre-Approval (PA) in Chrome River?

  • Yes, if there will be additional travel expenses (e.g., lodging, registration)*
  • No, if the chartered bus is the only trip expense

*Include a note on the PA that a chartered bus is being used for the trip. Do not include the Bus/Shuttle expense tile on the PA.

Invoices should be issued AFTER a Purchase Order (PO) has been placed in BuyUSI.

Invoices MUST reference a valid university PO number.

Departments should NOT ask for an invoice before a PO.
