C Spire offers online bill payment options through the Pay Bill and Express Pay links, as of 2015. The Pay Bill options requires logging in to an account, while Express Pay does not.
To pay a bill, visitors to CSpire.com should click on Pay Bill or Express Pay, both located under the My Account heading. Pay Bill brings up a sign-in screen, where the customer enters a user name and password. He then enters his payment information and submits a one-time payment.
From the Express Pay screen, the customer enters the mobile number on the account, his account number, and either the last four digits of his Social Security Number or his tax ID number. He then enters his payment information and submits a one-time payment.
Other payment options include Autopay, phone payments, mail payments and in-person payments. To set up Autopay, the customer logs in on CSpire.com and clicks Enroll in Autopay. He enters his payment information, and C Spire bills that payment source for every bill.
The customer calls the number on the website to make phone payments. For mail payments, the customer mails a check or money order to the address provided with his bill. For in-person payments, C Spire offers a store locator on its website.
