Hi there, EcoDKeesey.
Thank you for taking the time today to post in the QuickBooks Community. Unfortunately, at this time, the ability to pay off the entire outstanding invoice balance at once through the Pay Now button isn't available. Your customers will have to pay the invoices individually. However, I can see how this would be very beneficial to you and your customers alike, for that reason, I'm going to recommend to our product development team that this feature gets added to a future update to the product. You can view our QuickBooks Blogspot to see updates and changes made in product, as they're made. I'm also including a couple helpful articles below.
If you have any other questions, please post them here. I look forward to helping you with your QuickBooks needs and have a lovely Tuesday afternoon.
