Since you indicated that this receipt is NOT for an expense charged to a Remarq credit card, it must be an out-of-pocket expense paid by you using your own cash or personal card.
If you paid for the expense out of pocket (using your own cash or personal card), submit the receipt using the appropriate Break & Expense form so you can be reimbursed.
