CRM

Customer relations management (CRM) software as a product category encompasses a vast
array of software offerings, by no means all of which are designed around the needs of telecommunications
service providers.
The term most commonly refers to software used in call centers by sales agents and
telemarketers, though it can also include software for facilitating online transactions involving
sales, modifications of services, and service requests.
CRM will normally tie in with billing software and will also communicate with a central
database of customer profiles and subscription information.
