View directions with screen prints on how to use Gateway for looking up payment status. Alternatively, here's a quick list:
Pull up your Purchase Order in Gateway.
Click on the “Invoices” tab.
Click on the invoice in question.
Now that you’re viewing your invoice in Gateway, look for “Pay Status in “AP Information” on the right side of the screen.
If the status is Payable: This means AP has marked the invoice as “ok to pay”. PeopleSoft has queued up the invoice to send out a check.
If the status is In Process: Click on the “Approvals” tab, to see where in the process your invoice is. You will see which step the invoice is in, by looking for the word “Active”.
