Log into your account on the portal and select invoices.
Select “Past Due” and check the specific invoices you would like to apply your invoice credit to.
Select “Make a Payment.”
Ensure the “Apply Invoice Credit” box is checked.
Select “Pay with Credit.”
This will apply the credit to the selected unpaid invoices.
If the credit amount does not cover the entire amount due, then you can select other payment options such as ACH or credit card to pay the balance.
