The Upgrade & Save Checkout Extension is a Shopify Plus checkout extension that lets customers convert one-time purchases to subscriptions or modify existing subscriptions at checkout. We built a checkout UI extension that shows subscription upgrade options during the purchase flow. This is for Shopify Plus merchants who want to increase subscription adoption at the point of highest intent—right when customers are buying. Customers see subscription options at checkout, can upgrade with one click, and save money immediately. Higher subscription conversion rates, more predictable revenue, and better customer value without post-purchase friction.
