Once you have recieved an Invoice in your email, follow the link provided, or on the menu bar, go to "Services" tab, and scroll all the way down to where you will see "Pay an Invoice". All that is needed from the invoice is:
- Customer ID
- Invoice #
(which can both be found at the top right corner of your Invoice.)
Once a payment is processed, a receipt and "paid" invoice will be emailed to you!
