If you have multiple charges, you can pay all charges with one credit card transaction.
The last step of the registration process is the “Review and confirm” page. If a charge is involved, it will display two buttons:
“Invoice me” – Generates a charge only. Use this when you aren’t ready to pay yet. It will add the charge to the transaction.
“Pay online” – Generates a charge and starts the payment process. Use this when you are ready to pay.
When you click on either button a running total of your charges will be displayed in a small window in the lower right corner of your browser. This window will be displayed any time you have outstanding charges and you are logged in.
