- Enter the amount to Credit into Payment Amount.
- Select the Payment Method.
- If you are adding credit to the account and there are no invoices to be paid, you will receive the message below.
- Click Ok to continue.
- If you are also paying an invoice, the Invoice Selector will appear.
- Select the invoice and click OK.
- Initially, you will receive a warning that your invoice doesn't balance.
