our call

Start with Subkit — 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.
