LEXCIS invoices are generated on a monthly basis. You may receive only one statement per month for your LEXCIS billed products and/or services. This invoice contains products and/or services you purchase from CenturyLink.

You may receive your LEXCIS billing one of two ways:

  • Paper - A paper LEXCIS invoice is generated which contains the products and/or services and the amount for each billable item and mailed to you. A supporting Monthly Detail Report that details the charges is also generated and mailed to you.

  • Automated - The LEXCIS invoice is generated and includes the quantities, rates, and descriptions of your products and/or services. In addition a pay stub will be sent to you for the return of your payment. This automated invoice is sent to you via email.


General dispute process activities are described in the Billing Information - Dispute Process.
