What is a common revenue model in e-commerce where users pay a fixed amount periodically to access products or services?

The common revenue model in e-commerce where users pay a fixed amount periodically to access products or services is known as the Subscription Model.

Here's a step-by-step explanation:

1. The Subscription Model is a business model where a customer must pay a recurring price at regular intervals for access to a product or service.

2. This model is commonly used in various industries including digital media, software, and e-commerce.

3. In e-commerce, this model is often used for products that are consumed regularly and can be replenished, such as food, personal care products, and household items. It's also used for services like digital streaming platforms, online learning platforms, and more.

4. Customers typically subscribe to the service, and the payment is automatically deducted from their account periodically (monthly, quarterly, annually, etc.).

5. This model benefits businesses by providing a predictable and recurring revenue stream. For customers, it offers convenience and often cost savings.

6. Examples of companies using this model include Netflix, Amazon Prime, and Spotify.
