Welcome to the CST Co. Payment Portal.

You may use this portal to make payment on your account using a credit card or through ACH. Please have the CST Co. account number (in subject line of email or the Re: xxxxxxx in the letter) and zip code ready to validate your account for proper application of your payment.

CST Co. uses Pay N Seconds, a third-party payment processor, specializing in secure bill payment options. To submit a payment through this service, simply click on the Click to Pay link below and you will be instantly directed to Pay N Seconds.


Credit Card:

As a third-party payment processor, Pay N Seconds charges a fee when using a credit card to make payments.


There is no charge to you for using ACH to make payments. Using ACH initiates a debit entry to your checking account. This is like writing a virtual check. Your payment will be deducted directly from your checking account.

If you would like to discuss your account with a CST representative, you may call us at 1-800-626-5873.
