Filter invoices by Payment Method > External to narrow down your list to invoices eligible for payment that are flagged to be paid externally. Then select the invoice you want to mark as paid to view the detail screen. NOTE: Invoices or invoices of vendors flagged to be paid externally will never appear in the “Pay Invoice” grid.
At the top right of the screen, click on the “Paid Outside” button to open a memo window. Enter the payment date and enter any description or memo you see fit, then click on the “Submit” button. If you do not want to push this payment into your ERP, be sure to select the option at the bottom before submitting.
