Start with Subflow — highest vibe code, weakest moat.

Skio

If you are a single Shopify merchant paying thousands in transaction fees, you can easily build a custom customer portal and cancellation flow on top of Shopify's native APIs using AI. Rebuilding the entire enterprise suite with zero-downtime migration, deep Klaviyo integrations, and payment recovery logic is significantly harder.

you can rebuild

  • Passwordless customer portal for skipping, swapping, or pausing subscriptions
  • Build-a-box dynamic bundle selector UI
  • Multi-step cancellation flow builder with deflection offers
  • Basic subscription creation using Shopify Selling Plan API
  • Automated email notifications via Klaviyo webhook integrations

what you lose

  • Dedicated human migration engineering team to move subscription billing tokens securely without customer dropoff.
  • Pre-built, maintained integrations with dozens of DTC stack tools (Klaviyo, Postscript, Gorgias, Triple Whale, Fondue).
  • AI-driven payment retry timing optimization for recovering failed recurring credit card transactions.
  • Bundled 1-way and 2-way SMS subscription management capabilities (SkioSMS).
  • Turnkey no-code visual flow builders for customer retention and dynamic build-a-box bundles.

real moats

  • Deep ecosystem integrations with Klaviyo, Gorgias, Recharge (parent), Yotpo, and Shopify Flow.
  • Data advantages in churn prediction, automated payment retry timing optimization, and retention benchmarking across 1,000+ brands.
  • Dedicated onboarding and migration services that migrate tens of thousands of active subscription tokens with zero customer disruption.

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
