In most cases you can update your credit card details as follow:
1) If you received an invoice email, just click the link in the email which will take you to the GoCodes billing portal where you will be able to view the invoice and make your payment via your credit card. Make sure you check the 'Save Card' option if you want to use this card automatically for future payments.
2) If you are the current billing contact for your account, you can visit our billing portal here and signup/login to view all your estimates/invoices and maintain your payment card details.
