Accounts Payable FAQ

Log in to the iSupplier portal and enter your invoice number, purchase order, invoice date, or invoice amount to check your invoice status.

The most common reasons why an invoice is not listed are:

  • Accounts payable has not received your invoice (see invoice instructions).
  • Your invoice was received, but the purchase order number was missing or incorrect.
  • You have billed against a purchase order that has already been billed and paid in full.

Invoices are generally paid at the price and quantity ordered, delivered, and billed. In some instances, the payment amount may be less than billed due to an item that was returned or a credit invoice offsetting your payment.

The most common reasons why invoices are on hold are:

  • PRICE: Unit price being billed is greater than unit price in the contract.
  • QTY REC: Quantity billed is more than quantity received. This occurs if you have billed more than the PO allows, or if the user has not yet entered a receipt.
  • IPM VERIFICATION HOLD: This invoice is a paper invoice and has not yet been matched by the AP analyst.
  • MISCELLANEOUS HOLD (AP): There is an item on your invoice that does not agree with the purchase order.


A receipt is a transaction created in the Oracle system when materials or services are indicated as having been received by the employee responsible for the order. An invoice cannot be paid until a receipt is entered in the system.

Go to the Accounts Payable Direct Payment Permits page, where you can print out a copy.

Invoice numbers are listed on your check stubs. You may also review payment details by logging in to iSupplier.

If you didn’t receive a check after two weeks, send an email to requesting a stop payment on the check. Once the stop payment is confirmed, we’ll issue a new check.
