How can a traditional business modify its IT systems to focus more on subscribers and monetize customer relationships over time?

The shift from traditional business models to subscription services presents several challenges to existing IT systems and practices. Traditional IT systems are typically designed around stock keeping units, not subscribers. In a subscription model, the system needs to identify and track subscribers to monetize customer relationships over time. It needs to conduct rapid price testing for new offerings, facilitate easy sign-up, upgrade, and renewal processes for customers, handle sales to both individuals and large enterprises, cope with high-volume recurring payments, and measure recurring revenue. These requirements can pose significant challenges to traditional IT systems and practices.
