Bundles thrive on simplicity, offering customers curated product combinations at attractive prices. However, certain purchase options, such as subscriptions, pre-orders, or try-before-you-buy (TBYB) programs, introduce layers of complexity that bundles may struggle to accommodate.
Subscriptions involve recurring payments and automated deliveries, which may clash with the one-time purchase model of bundles. Because of this, subscriptions and similar purchase options are not supported with Zenbox.
When a subscription step is included in a bundle, Shopify rejects the checkout request and returns a 422 Unprocessable Entity error.
Common causes
Subscription step added to the bundle
The bundle includes a subscription or recurring payment option that Shopify cannot process alongside a one-time purchase.
Other unsupported recurring options
Pre-orders, TBYB, or similar recurring programs may also cause the same error, as they rely on a different purchase flow that is incompatible with bundles.
How to fix
Edit the bundle.
Remove the Subscription step or any unsupported recurring option.
Save and refresh the bundle.
Test the checkout flow again.
