Can I vibe code Ongoing Subscriptions?

CLONE — YOU CAN REBUILD THE FEATURE

What you actually pay Ongoing for is a turnkey admin UI, liquid theme integration for selling plans, and an out-of-the-box customer management portal. Shopify natively handles credit card vaulting, billing cycle execution, and tokenization through its Subscription Contracts GraphQL API. The app acts as an orchestration UI layer. Rebuilding this for a single store requires configuring Shopify Selling Plan Groups via GraphQL, listening to renewal webhooks, and hosting an App Proxy endpoint for customer subscription modifications.

Why this verdict

Shopify handles payment vaulting and card processing natively through its Subscription Contracts API. Ongoing Subscriptions provides an admin dashboard, discount configurations, and an embedded customer portal. Rebuilding a custom in-house subscription controller for a single store with Claude/Cursor requires executing standard webhooks and GraphQL mutations.

The one-shot build promptbuild it on Lovable

Build a custom, lightweight Shopify subscription management system using Next.js (App Router), TypeScript, and the Shopify Admin GraphQL API (2024-01 or newer).

1. DATA MODEL & SELLING PLAN CREATION:
- Construct an admin panel that uses `sellingPlanGroupCreate` GraphQL mutation to register selling plans (e.g., 'Deliver every 30 days - 10% off').
- Associate products or variants with the generated `SellingPlanGroup` IDs.
- Store local mappings in a Supabase Postgres database containing store_id, selling_plan_group_id, discount_percentage, and frequency_interval (DAY/WEEK/MONTH).

2. CUSTOMER PORTAL (SHOPIFY APP PROXY):
- Create an API route designed to run behind a Shopify App Proxy (`/apps/subscriptions/portal`).
- Verify the Shopify HMAC signature on all incoming proxy requests.
- Fetch active subscription contracts for the authenticated customer ID using `subscriptionContracts` GraphQL query.
- Render an interface letting customers perform 4 mutations: `subscriptionContractPause`, `subscriptionContractResume`, `subscriptionContractCancel`, and `subscriptionContractSkip` (advancing `nextBillingDate`).

3. AUTOMATED RENEWAL & BILLING CYCLE HANDLER:
- Implement a webhook endpoint listening for `SUBSCRIPTION_CONTRACTS_UPDATE` and `SUBSCRIPTION_BILLING_ATTEMPTS_FAILURE`.
- On payment failure, trigger an email alert via Resend API notifying the customer to update their payment method.
- Expose an endpoint to generate a payment update link using the `subscriptionContractUpdatePaymentMethodUrl` mutation.

4. OUT OF SCOPE:
- Do not build custom credit card vaulting or PCI compliance code; rely entirely on Shopify Payments native vaulting.
- Do not build multi-currency handling outside of standard Shopify Presentment Currencies.
- Avoid legacy REST APIs; strictly use Shopify GraphQL Admin API.

✓Subscriber transactional notification emails via Klaviyo or Resend

What you lose

×Turnkey setup with zero infrastructure to host or maintain
×Out-of-the-box Theme App Extensions for complex custom themes
×Pre-built edge-case handling for Shopify API version upgrades
×Pre-configured dunning schedules and automated credit card update prompts
×One-click migration scripts from Recharge, Bold, or Seal
