Thank you for joining the thread, @TSOSNJ.
I'll share some insights to help clear things up for you.
You are receiving this error message because bill pay can currently only pay bills for the total amount of the bill. Discounts and credits must be applied ahead of time:
- For Credits, we can first apply for the bill credit in the pay bills screen, then change the amount to pay to zero and save it.
- For discounts, go to the bill where the discount will be applied. Insert a discount account or item(s) to apply to the bill and save.
You may refer to this article for more details: Pay bills online from QuickBooks Desktop.
You can also look into these steps if this works for you.
- On the Pay Bills screen. Under the Set Credits button, you'll see a Payment section.
- The payment method in the drop-down list has to be Schedule Online Payment
- Change the method to Check, and you'll be able to apply for credit.
