CSG Systems International has inked a billing deal with Comcast Cable. The expansion and extension of the contract is for providing residential billing services to Comcast Cable through June 30, 2019.

Currently, CSG provides its pre-integrated customer care and billing solution to nearly two-thirds of Comcast’s existing residential customers. The expanded contract provides the framework for Comcast to consolidate its residential business onto CSG’s billing solution.

Initially under the new agreement, Comcast plans to add approximately 2.3 million residential customers onto the CSG billing solution in early 2015, with the opportunity for additional customer account migrations to CSG as part of any future consolidation or standardization.
