Add subscription sign-up option at checkout

The merchant would like the ability to let customers subscribe directly at checkout, rather than only from the product page or widget. This feature would give customers a seamless opportunity to convert a one-time purchase into a subscription just before completing their order.

This improvement would make subscriptions more visible and convenient, helping merchants increase subscription adoption while making the experience smoother for customers. Adding the option to subscribe at checkout could significantly boost conversion rates and recurring revenue.
