Subscription pricing models are a type of business model in which customers pay for access to goods or services through predetermined, regular payments. This type of pricing can be used for products ranging from physical goods like subscriptions to magazines and newspapers, to digital products such as streaming video and audio services. In this model, customers receive ongoing access to the product or service they have subscribed to, while the company providing it earns ongoing income. For companies adopting subscription-based pricing, the advantages include a predictable, reliable stream of revenue, better customer retention, and improved customer relationships.
