This guide walks you through how to enable and configure these options in UpCart, and includes tips for customizing button text, display labels, and subscription plan formatting. When enabled, the module adds two interactive options to qualifying cart items:

These options appear as dropdowns or buttons next to each eligible product, allowing customers to easily change their purchase type before checking out.

When a product supports subscription plans, customers will see a prompt in the cart to upgrade their purchase. If your product has multiple subscription intervals, the customer can choose between them. They can also revert to a one-time purchase if you allow it.

By default, the upgrade button displays the Selling Plan Group Name, which is pulled directly from your subscription app. You can override this by editing the button label and removing the {{selling_plan_group_name}} variable if needed.

This setting controls how subscription intervals are shown in the dropdown. The text includes the {{selling_plan_name}} variable, which reflects the subscription frequency (e.g. “Delivered every month”). To edit this text, you’ll need to check the box labeled Allow Subscription Plan Options Text Override. This will unlock a field where you can enter your custom label.

This is the label shown when a customer chooses not to subscribe. The default is “One-time purchase.” To customize this label, make sure the Allow Subscription Plan Options Text Override box is enabled, then scroll to the text field directly beneath the Subscription Plan Options Text section.

If a product supports both subscriptions and one-time purchases, customers will also see the option to switch back. This is presented in the same dropdown used to select subscription plans.

To restrict customers from switching back to a one-time purchase, enable the Prevent Downgrades setting at the bottom of the Subscription Upgrades configuration. When this is checked, the “One-time purchase” option is removed from the dropdown entirely.
