Purchase Order Invoicing Requirements

The following criteria must be met in order for Accounts Payable to process an invoice and schedule payment per the terms specified on the purchase order (e.g. Net 30 days from date of invoice):

  • The document must be an invoice, NOT a quote, order acknowledgement, sales receipt, or packing list.
  • The invoice must bill Stanford University.
  • The invoice must include a "Remit to" address.
  • There must be a Stanford Purchase Order Number referenced on the invoice.
  • Invoices for amounts greater than $5,000 require departments to certify receipt of the goods or services (see Methods for Submitting Invoices to Accounts Payable below for department approval instructions).

Methods for Submitting Invoices to Accounts Payable

Ideally, suppliers submit invoices directly to Accounts Payable (AP), ensuring the most legible document and efficient processing. When suppliers send invoices to departments rather than to Accounts Payable, the department must forward the invoice to Accounts Payable using one of the methods outlined below.

Methods for Submitting Invoices to Accounts Payable
In Order of Preference Instructions and Department Approval
1.  Supplier mails invoice directly to AP at

Stanford University
Accounts Payable
3145 Porter Drive
Palo Alto, CA 94304
Mail Code: 8440

See Supplier Instructions for Submitting Invoices.

  • For invoices greater than $5,000, the requisition originator will receive an email notification requesting department approval.
2.  Department electronically uploads invoice (via the Requisition Purchase Order Query Tool)

See how to Upload Electronic File of Invoice to Accounts Payable.

  • When requisition originators or authorized approvers upload invoices, they will see a check box noting "Invoice approved for payment" which serves as department approval.
  • If someone other than the requisition originator or authorized approver uploads an invoice, the check box is not visible. Invoices greater than $5,000 will be placed on hold by Accounts Payable and the originator will receive an email notification with instructions to contact the Financial Support Center (3-2772) to release the hold by providing their approval to pay.
3.  Department mails original hard-copy invoice to AP at

Stanford University
Accounts Payable
3145 Porter Drive
Palo Alto, CA 94304
Mail Code: 8440

See Mail an Invoice to Accounts Payable for address and payment handling options.

  • For invoices of $5,000 or more, departments must indicate approval or they will be placed on hold by AP and the requisition originator will receive an email notification requesting department approval.

Notes:

  • Invoice images and payment status can be viewed using the Requisition and Purchase Orders Query tool. For instructions, see View Requisitions, Purchase Orders or Invoices.
  • Invoices for purchases made through Stanford's SmartMart Catalogs are electronically sent by the supplier to Accounts Payable for payment processing.
