our call
Start with Bold Subscriptions — highest vibe code, weakest moat.
Bold Subscriptions
Bold Subscriptions used to be a massive engineering task when payment vaulting had to happen off-checkout. Today, Shopify's Subscription Contracts API handles PCI compliance, payment vaulting, and checkout logic natively. The app is mostly a UI and dunning orchestrator.
you can rebuild
- Subscription group creation (standard, prepaid, convertible options)
- Customer portal for pausing, skipping, and swapping subscription items
- Automated dunning retries and payment retry schedules
- Shopify Checkout integration via Subscription Contracts API
- Basic discount logic (percentage off, dynamic discounts)
what you lose
- ProsperStack native cancellation prevention integrations (unless built custom).
- Dedicated tier 1 enterprise migration assistance for moving off legacy gateways.
- Turnkey pre-built theme code snippets for older liquid themes without developer intervention.
- Multi-platform compatibility (e.g. unified dashboard if operating BigCommerce + Shopify simultaneously).
real moats
- Decade-long migration pipelines holding thousands of legacy billing tokens in custom vaults.
- Deep pre-built integrations with legacy tech stacks and custom Shopify theme installations.
- White-glove migration services handling enterprise data transformation from competitors.
Smartrr
While creating a basic recurring order generator is easy, building a production-grade subscription engine requires orchestrating Shopify's Subscription Contracts API, tokenized payment retries, and dunning cycles. A DIY solution risks silent billing failures, customer churn, and payment gateway compliance gaps.
you can rebuild
- Custom customer account portal for skipping or pausing renewals
- Product swap UI and bundle builder widgets
- Basic dunning email trigger notifications
- Order frequency schedule selector on product pages
- Custom discount codes applied to recurring cycles

- Pre-built integrations with Klaviyo, Gorgias, and Attentive subscription events
- Turnkey dunning/retries optimized for failed credit card tokens
- Built-in churn analytics and cancellation survey branching
- Ongoing maintenance against Shopify Subscription API breaking changes
real moats
