Discounting an Open Order
During the payment process, open orders can accept discount codes. In the Payment Wizard, when paying an open order, note the Promo Code field at the bottom of the page.
Enter the discount code into the Promo Code field and click Apply. Once applied, the discount amount will be noted on the line item, the total amount will be adjusted, and you can proceed to make a payment.
Note: Staff and non-staff users have the ability to discount an open order.
