  • These procurements must be processed through Purdue’s eProcurement system and issued a purchase order prior to delivery of goods or services.
  • Pricing currency from suppliers should be in USD (US Dollars).

Procurements of $9,999 and above (Formal Solicitation) 

  • These require that a formal competitive process be followed.
  • The formal solicitation involves publishing bid opportunities that include the solicitation number, date of opening, date of closing and the requirements of the University.
  • Purdue encourages inclusion of MBE/WBE/VBE vendors whenever possible.
  • All formal solicitations (bids and requests for proposals) are issued and received through Purdue’s eProcurement system.

There are two types of solicitation processes

The Accounts Payable Department is responsible for making payment to vendors for liabilities incurred by the University. Accounts Payable will issue payment within the established payment term upon receipt of all necessary documentation. Documentation required prior to making payment is as follows:

  • Purchase Order issued by the University or signed Contract.
  • Invoice from Vendor (reviewed for accuracy).
  • Payment authorization from the receiving department.

To assist Accounts Payable in making prompt payment, vendors are required to submit their invoices immediately following the delivery of goods or services. Items must be received in our system, by the ordering department, prior to payment being released.

Invoices should be submitted electronically via the Ariba network.

Invoices must match the purchase order, line for line, and must reference:

  • Appropriate purchase order and/or contract number.
  • Itemized quantities, utilizing the same unit of measure as listed on the purchase order.
  • Description of goods and/or services.
  • Unit prices and total price.

Discrepancies between the PO and the invoice can delay payment while being reviewed for approval. Vendors should direct all inquiries regarding payment status by email. Purdue University is a tax-exempt entity.

Purdue University’s available payment terms are as follows:

Automated Clearing House (ACH) Options

  • 3% discount for the payment within 10 days, Net paid within 45 days.
  • 2% discount for the payment within 20 days, Net paid within 45 days.
  • 1% discount for the payment within 30 days, Net paid within 45 days.
  • Net paid within 45 days, no discount.

Single Use Account: Pay immediately via Virtual Credit Card. View Purdue's purchasing terms and conditions.

Ariba Supplier Options

Ariba suppliers have three options available to submit their invoices electronically through Ariba. If one of the three options is not established by the supplier — and the supplier chooses to submit manual invoices — payment terms will automatically be net paid within 60 days, no discount.

  • Option 1: Integration - Allows the supplier to automate processes like purchase order and invoice data entry. The integration option is contingent on the supplier’s technological ability/capability. Typically, there is some form of cXML or EDI integration so that invoices send electronically to Purdue through the Ariba network. Suppliers can specify Online, cXML or EDI as their default routing method for invoices. This option is best suited for suppliers with over 200-250 invoices per year.

  • Option 2: Online Invoicing - Uses the supplier’s Ariba network account. Suppliers log into their account, identify a purchase order (PO) to invoice and click "process invoice." This will create the invoice and allow the supplier to review the pre-populated information before submitting the invoice. The invoice will send automatically to the buyer’s Ariba procure-to-pay (P2P) system through the Ariba network. This option is best suited for suppliers with limited technical ability who submit less than 200 invoices per year.

  • Option 3: PDF Invoicing - Allows suppliers to submit invoices through the Ariba network. This option is designed for suppliers who might not have the technological ability or capability to do a full integration. This option requires some setup prior to utilizing. Once setup is complete, the supplier has the ability to send digital invoices to a designated Ariba email address. Invoices process in the Ariba network and send to the buyer procure-to-pay (P2P) application. This option can be done as quickly as sending an invoice to Purdue's accounts payable department. The only difference is the email recipient address. This option is best suited for suppliers with 200+ invoices per year.
