CSPs are increasingly focusing on business customers, especially small businesses, which represent a large but previously underserved market. As a result, spending on business services-related OSS/BSS systems is growing faster than overall OSS/BSS spending. Specifically, spending is shifting from network-oriented to more customer-oriented systems that better support the specialized needs of businesses. This includes adding functionality for billing, customer care, and service fulfillment focused on the enterprise market. While large enterprises remain an important revenue source, small and medium businesses collectively represent the majority of businesses and addressing their needs through enhanced automation and self-service capabilities will be key to future growth for CSPs.
