👉 The subscription fluid, often referred to as the "fluid model," is a flexible pricing strategy where users pay for access to services or features based on actual usage rather than fixed monthly or annual plans. This model allows users to subscribe only for the amount of service they need, paying as they go and scaling up or down according to their usage. For example, a streaming service might charge based on the number of hours watched or the number of devices accessed. This approach provides cost savings for users who only occasionally use premium features and offers businesses a more predictable revenue stream, as they can adjust their pricing based on demand. The subscription fluid aims to enhance user experience by offering tailored access and flexibility while maintaining profitability for service providers.
