CLONE — YOU CAN REBUILD THE FEATURE

When building a subscription app on Shopify today, you are not building a billing engine—Shopify already provides payment vaulting, PCI compliance, and automated charging infrastructure via its Subscription APIs. You pay SaaS fees mostly for an out-of-the-box customer management portal widget and automated email triggers for failed billing attempts. Rebuilding this requires registering selling plans via Shopify GraphQL, hosting a portal using Shopify App Proxies or Theme App Extensions, and listening to billing webhooks. You lose turnkey theme widgets and out-of-the-box dunning flows, but gain zero transaction markups and total UI control.

Why this verdict

Shopify's Subscription Contracts API manages payment method vaulting, billing schedules, and tokenized charges. Native Subscriptions is primarily a custom customer portal UI and an administrative wrapper around standard GraphQL endpoints.

The one-shot build promptbuild it on Lovable

Build a minimal, self-hosted Shopify Subscription Management application using Node.js, TypeScript, Express, and Prisma, leveraging Shopify's native Subscription Contracts API.

1. Architecture & Setup:
- Create a Shopify Embedded App using App Bridge and Node.js.
- Implement standard Shopify OAuth authentication and webhooks handling.
- Configure a Shopify App Proxy route at `/apps/subscriptions` to serve the customer portal UI inside the store's frontend theme.

2. GraphQL & Selling Plans:
- Create administrative routes to create and manage Shopify `sellingPlanGroup` entities using the Admin GraphQL API (`sellingPlanGroupCreate`).
- Store local mappings of `sellingPlanGroupId`, `sellingPlanId`, and Shopify variant IDs in PostgreSQL.

3. Webhooks & Contract Lifecycle:
- Register webhooks for `SUBSCRIPTION_CONTRACTS_CREATE`, `SUBSCRIPTION_CONTRACTS_UPDATE`, and `SUBSCRIPTION_BILLING_ATTEMPTS_FAILURE`.
- Store subscription contract states (active, paused, cancelled) in PostgreSQL for audit logging.
- When `SUBSCRIPTION_BILLING_ATTEMPTS_FAILURE` fires, trigger an email via Postmark containing a Shopify customer self-service portal link to update their payment method.

4. Customer Portal Endpoints (App Proxy):
- Implement verification logic for Shopify App Proxy requests using HMAC signatures.
- Expose `/api/portal/subscription/skip` to advance contract next billing date using `subscriptionContractSkip` GraphQL mutation.
- Expose `/api/portal/subscription/pause` and `/api/portal/subscription/resume` using `subscriptionContractPause` and `subscriptionContractAtomicRegister` mutations.
- Expose `/api/portal/subscription/swap` to update contract line items.

5. Out of Scope & Limits:
- Do NOT build card vaulting or PCI handling; rely entirely on Shopify Payment Customization and payment method tokens.
- Do NOT build custom checkout flows; rely on standard Shopify Checkout with attached Selling Plans.

What you keep, what you lose

The honest trade of rebuilding it yourself.

What you can actually replace

✓Recurring billing schedule generation via Shopify Subscription API
✓Customer self-service portal for pausing, skipping, and swapping items
✓Subscription discount rules and frequency selector widgets on product pages
✓Merchant admin dashboard for managing subscriber contracts
✓Basic cancellation flow with discount offer incentives

What you lose

×Pre-styled theme widgets compatible across hundreds of standard Shopify themes
×Turnkey dunning sequence engine with automatic payment retry schedules
×One-click migration tools for importing legacy subscription contracts from Recharge or Bold
×Pre-built analytics dashboards for tracking MRR, cohort retention, and churn reasons
×Native helpdesk integrations (e.g., Gorgias) for managing subscriptions in support tickets

Why people still pay — the real moats

Moats

— Deep ecosystem lock-in via Shopify Theme App Extensions across diverse merchant themes
— Historical contract state machine management across thousands of active store stores
— Turnkey automated dunning logic fine-tuned to maximize card retry recovery rates

Hard parts

— Synchronizing local app database states with Shopify Subscription Contract GraphQL webhooks in real time
— Securing customer portal endpoints via Shopify App Proxy verification without forcing separate customer logins
— Managing inventory allocations prior to executing automated recurring draft order charges
— Maintaining compatibility across frequent updates to Shopify Admin GraphQL API versions
— Handling edge cases around expired credit cards and sending frictionless update-payment links
— Supporting dynamic price updates across active contracts without invalidating customer permissions
— Calculating taxes and dynamic shipping rates accurately on scheduled recurring orders
— Managing customer support tickets related to failed draft order creation or inventory lockup

Native Subscriptions is primarily a custom customer portal UI and an administrative wrapper around standard GraphQL endpoints. An MVP takes roughly 1 weekend; matching the product properly is closer to 1-2 months, to build flexible portal widgets, robust dunning retries, and theme integration.

+How long does it take to rebuild Native Subscriptions?

A usable internal version: 1 weekend. A version you would sell or bet a business on: 1-2 months, to build flexible portal widgets, robust dunning retries, and theme integration, mostly spent on synchronizing local app database states with shopify subscription contract graphql webhooks in real time.

+What do you actually lose by leaving Native Subscriptions?

Pre-styled theme widgets compatible across hundreds of standard Shopify themes Turnkey dunning sequence engine with automatic payment retry schedules One-click migration tools for importing legacy subscription contracts from Recharge or Bold

+Is it legal to build a Native Subscriptions alternative?

Building a competing product with your own code is normal competition. Copying their code, trademarks, brand assets or scraping their platform is not. Use the prompt to build your own implementation of common features.
