RebillCart is in beta — feature availability may change before general release.
Getting StartedAdd the Storefront Widget

Add the storefront widget

RebillCart ships one theme app block that shows subscription options on your product pages. It automatically adapts to what a product offers — a plain “Subscribe & save” toggle, a curated monthly box, or a build-your-own-box picker — so you only ever add a single block per template.

Add the block in the theme editor

  1. In your Shopify admin, go to Online Store → Themes and click Customize on your live (or a duplicate) theme.
  2. Navigate to a product page template.
  3. Click Add block in the section where you want the subscription option to appear (typically just below price, above the Add to cart button).
  4. Choose the RebillCart Subscription Widget block.
  5. Save.

The block renders differently depending on what the product has attached to it:

The product has…Widget shows
A regular subscription plan onlyOne-time purchase · Subscribe & save (with frequency picker)
A monthly box plan onlyOne-time purchase · Monthly box (with “what’s inside” preview)
BothOne-time · Subscribe & save · Monthly box, all as one option group
NeitherNothing — the block stays hidden

Customize the look

From the same block’s settings panel in the theme editor you can change, without touching code:

  • Layout of the purchase options — classic list, cards, a comparison table, or tabs.
  • Frequency picker style — dropdown, pills, tabs, or cards, each showing real “Save X%” badges pulled from your plan’s actual discount (never a hand-typed label).
  • Row order — one-time first vs. subscribe-first, and box-first vs. box-last.
  • Colors, corner radius, and shadow to match your theme, plus a sandboxed Custom CSS field for anything the built-in controls don’t cover.
  • An optional benefits list and trust row under the subscribe option.

See the full Storefront Widget feature reference for every setting, and Customize the storefront widget for a walkthrough of the most common presentation changes.

Verify it works

Before pointing customers at it:

  1. Open the product page on your online store preview (not just the theme editor preview — test the real storefront).
  2. Select the subscribe option and add to cart.
  3. Complete a test checkout (Shopify’s test payment gateways  work in a development store) and confirm the order appears with a subscription contract.
  4. Check that the new subscription shows up under Subscriptions in the RebillCart admin.
