Some e-commerce companies employ the approach of combining one-time purchases and subscriptions to increase revenue growth and consumer engagement. Businesses can adapt to various client preferences and boost income by giving customers the choice to buy a good or service as a one-time purchase or as a subscription. Combining one-time purchases and subscriptions can help e-commerce organisations expand their revenue, increase client lifetime value, and decrease churn. Businesses may increase customer happiness and engagement by giving customers a variety of buying options.
