Custom Amount Payment

I cannot find somewhere for a customer to make a custom payment on the newest version. I believe the old version allowed them to make a payment, but this one I can’t find. I have a customer that we trade out work for internet credit, and the amount due is less than the invoice amount. How can I pay off just the amount due?

Good day
