The Corporate Accounting vendor self-service website allows vendors to check on the status of their invoices, track the status of payments and validate purchase order numbers. It also provides contact information so that vendors can resolve invoices that are on hold or have an incomplete (I) status.

Vendors can use this site to obtain information and answers for commonly asked payment questions, including:

  • Where is my payment?
  • What is this check for?
  • Is this a valid purchase order (PO)?
  • How do I get a replacement check?
  • How do I update my address?
  • Why were funds withheld from my payment?

If the vendor self-service website states that a check has been issued but you have not received the check for two weeks, you may submit a Stop Payment form to have a check reissued. For additional information, see How to Stop Payment & Cancel Checks in Related Information.


All vendors who do business with UCLA can register at the vendor self-service website at no cost. Click on the "Register" button to enter your information and set up an account and password.

In order to complete the registration process, your taxpayer identification number (TIN) must be on file with Accounts Payable. If you encounter registration difficulties, a TIN for your company may not exist in our system. In this case, please complete a W-9 form and send it to Accounts Payable so that we may update our records.
