our call

Start with Subflow — highest vibe code, weakest moat.

Subflow

Subflow provides a structured subscription layer, billing schedule engine, and customer portal. Stripe Billing API handles the underlying payment collection, card vaulting, and recurring logic natively. If you have custom web applications, building this around Stripe APIs is quick, but managing dunning edge cases and payment retries requires effort.

you can rebuild

  • Self-service customer subscription portal (pause, skip, swap, cancel)
  • Recurring billing cycle logic and automated renewal triggers
  • Transactional billing emails for successful payments and failures
  • Subscription plan setup (frequency, discount tiers, trial periods)
  • Basic MRR, active subscriber, and churn reporting dashboard

what you lose

  • Turnkey PCI-compliant hosted subscription checkout pages
  • Pre-integrated dunning management algorithms optimized for card retries
  • Native plug-and-play integrations with popular email service providers (Klaviyo)
  • Built-in support for physical box order generation workflows
  • Zero-code subscription setup for non-technical team members

real moats

  • Payment gateway credit card token lock-in and migration risk
  • Deep ecosystem integrations with fulfillment, tax, and marketing platforms
  • Involuntary churn reduction algorithms refined across millions of transactions
