Hello there, RegC.
You can add a vendor credit, then apply it to the bill.
Here's how:
- Click the Plus sign (+) icon.
- Choose Vendor Credit.
- Choose the same account used on the bill, then enter the deduction amount.
- Click Save and close.
Now, pay the bill, then add the credit. Here's how:
- Open the bill, then click Make payment.
- Under Credits, choose the Vendor Credit.
- Click Save and close.
On the Bill payment page, you will see how much was billed, and how much was paid. Please check the screenshot below.

Let me know if you need more help. Have a good one!
