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.
Stay AI
You can replace Stay AI's core subscription portal, skip/swap logic, and basic cancellation flows with an AI-generated app in a couple of weeks. However, matching their automated reinforcement-learning save flows, churn prediction models, and zero-touch migration services requires serious custom ML data engineering and ongoing operations.
you can rebuild
- Customizable drag-and-drop customer portal (swap, skip, pause, delay)
- Cancellation survey flows and retention save offers
- Bundles and build-your-own box UI
- Gamified digital punch cards and loyalty milestones
- One-click add-on upsells inside the customer portal
what you lose
- Proprietary reinforcement-learning models for dynamic retention save offers
- Turnkey white-glove migration team to transfer raw contract data from legacy platforms
- Dedicated human subscription growth strategist
- Pre-configured multi-channel integrations (Attentive, Postscript, Gorgias, Rebuy)
- Benchmarked retention analytics compared against industry-wide DTC cohorts

- Reinforcement learning models trained across hundreds of DTC subscription brands
- High-touch, human-led white-glove migration services and dedicated growth strategists
