You can pay a due invoice directly within your account.
Pay Your Invoice
If you have an invoice due in your account, you will automatically be directed to the Billing section of your account to process the payment.
If you are not automatically redirected to your account billing, you can click the account settings icon in the bottom-left corner of the dashboard and click "My Account."
At the top of the page, click the Billing tab.
On the Billing page, scroll down until you see a section labeled Invoices. Next to the invoice that is due, click the Pay Now button.
Enter the credit card details that you want to use to pay invoices moving forward.
Once you are done, click "Pay" - the amount due will be charged to your credit card.
What if I have multiple overdue payments?
If your account has multiple past due payments, you are responsible for paying all outstanding balances to bring your account back to current status. Each overdue invoice payment must be submitted separately just like all other invoices.
