Be able to pay any amount you choose. Invoice $75 but you want to pay $150.
Your invoice says you owe $75 this week but you know you have a balance and want to pay extra. Be able to choose the amount you want to pay even if it’s over the invoice amount.

TOTALLY AGREE TOTALLY. My business has a very busy season and so easy to miss such payments before they went to QuickBooks billing, I was able to prepay more than I was billed for so I was not behind when so busy. Most industries have those very busy times.
