Which of the following payment models is most commonly used for eCommerce businesses?

The one-time payment model is the most commonly used payment method for eCommerce businesses due to its simplicity and straightforwardness. When customers make a one-time purchase, they can immediately acquire a product or service without the need for ongoing commitments. This model allows businesses to easily set prices for individual items, making it intuitive for customers to understand and complete the transaction.

Customers typically prefer one-time payments for physical goods, digital downloads, and single-use services, as it eliminates the complexities and potential long-term commitments associated with subscription models. Moreover, the one-time payment approach facilitates faster transactions, as there is no need for recurring billing cycles, notifications, or renewals, which can sometimes complicate the customer experience.

In contrast, while recurring subscriptions are popular in certain subscription-based services, they aren't as universally applicable across all eCommerce sectors. Installment payments may appeal to customers purchasing high-ticket items but aren't the predominant model for the vast majority of online transactions. The freemium model applies to a different context, mainly in software or digital service industries, where users gain access to a basic product for free while paying for advanced features.
