Review Procurement and Payment of Services Without a Purchase Requisition. This is a complete list of transactions that may be processed and payments made without a Purchase Order. If requested purchase is on this list, an Invoice Distribution Form may be submitted with invoice or price verification to Procurement Services for payment. Submit directly to the Foundation if utilizing a Foundation Invoice Voucher.

Responsible Party  Action 


Submits information on a Purchase Requisition listing Recommended Supplier. 

Process will be expedited if Department provides a written price quotation from the Recommended Supplier. 

If utilizing Grant accounts, documents must be approved by Grant and Contract Accounting within the Office of Sponsored Projects Administration.

If utilizing Foundation accounts, documents must be approved by SIU Foundation.

Department should know that purchases under the Small Purchase Maximum do not require bidding. However, due to the requirements of the Board of Trustees, Purchase Requisitions of $10,000 to $99,999.99 for non-professional services are encouraged to include comparative pricing. (Purchases over $99,999.99 will require Presidential approval up to $499,999.99 and purchases over $500,000 will require full Board of Trustees approval after the competitive process has been completed.) Buyer may competitively bid any Purchase Requisition at their discretion. 

Department should be aware that a Financial Disclosure form is required for any order or subcontract over $50,000. A Purchase Order cannot be issued until a completed Financial Disclosure has been received in Procurement Services.
