Autoship with selling plans — Vicubites

01Problem

Repeat customers want food to arrive on a schedule without leaving the product page or creating a separate subscription.

03Decision

Shopify Subscriptions for billing and a custom selling plan picker in the theme, bound to the product form with the HTML form attribute so it works without JavaScript.

04Build

Shopify Subscriptions owns the contracts and billing; the theme owns the experience. The picker lists each delivery frequency with its per-delivery price taken from the variant’s selling_plan_allocations, so discounts configured in the app are always what the shopper sees.

Inputs sit outside the product form in the markup but submit with it through the form attribute. No script is needed to send selling_plan with the cart request, and the same contract is what any subscription app (Recharge, Skio, Loop) reads.

B2B buyers on the blended store get the standard buy box: Shopify doesn’t allow subscription purchases in a B2B context, so the picker renders only when customer.b2b? is false and the product has selling plans.

05Quality

Prices read from selling_plan_allocations, never recalculated in the theme
