But the original order total was already authorized. So I needed to first find the new item. Then add it to the order. And finally authorize another payment for the new balance on the order.
It's slick how AC7 handles it. Just pull up the order line items and search for the item to add it to his order. Then pull up payments and add a second payment for the remaining balance of his order.
Took like 2 minutes to do it all with the customer on the phone.
Me a happy merchant
