I love this feature of charging my customer's a "convenience fee" for using a credit card payment online.  When a customer pays with a credit card online, it will charge them the invoice amount + 3% (or whatever percent you choose) and QBO would automatically make an invoice for the convenience fee and mark the respective invoice and convenience fee invoice as paid.

Issue:  Starting around the beginning of March 2021, QBO stopped automatically making the convenience fee invoice.  In the attached picture, you can see that this customer made online payments with a credit card.  In February (blue circle), you can see a convenience fee invoice.  In March (red circles), it stopped and the payment is now considered an over payment.  Please fix this QBO!
