our call

Start with Loop Subscriptions — highest vibe code, weakest moat.

Loop Subscriptions

You can easily build a custom Shopify subscription app that eliminates Loop's 1% transaction fee using native Shopify APIs in a few weeks. However, replacing Loop's deep app store integration ecosystem, white-glove migration scripts, and battle-tested dunning algorithms requires significant ongoing development.

you can rebuild

  • Basic recurring product subscriptions (Shopify Selling Plans integration)
  • Self-serve customer portal for skips, pauses, and product swaps
  • Basic cancellation save flows with pause/discount offers
  • Automated payment recovery (dunning retries)
  • Shopify Theme App Extensions for selling plan widgets on product pages

what you lose

  • Managed migration support to transfer active vaulted payment tokens from older platforms.
  • Out-of-the-box native integrations with marketing and support tools (Klaviyo, Gorgias, Attentive).
  • Dedicated Customer Success Manager and shared Slack support channel.
  • Gamified retention features like loyalty streak tracking and mystery rewards.
  • Built-in A/B testing infrastructure for cancellation flows.

real moats

  • Turnkey white-glove data migration pipelines from legacy systems like Recharge or Skio without subscription downtime or token loss.
  • Deep ecosystem integrations (Klaviyo, Gorgias, Smile.io, Attentive) built over years with dedicated webhooks and state syncing.
  • Battle-tested payment retry logic optimized against millions of historical transactions to maximize recovery rates.

SubscriptionFlow

If you process payments through Stripe or Braintree, their native subscription APIs eliminate the need for SubscriptionFlow. You only need a custom tool if you route recurring transactions across multiple disparate gateways simultaneously.

you can rebuild

  • Customer self-service portal (pause, upgrade, downgrade, cancel)
  • Automated dunning email schedules and retry logic
  • Discount and promo code engine for recurring items
  • Trial period conversion management
  • Basic MRR, ARR, LTV, and churn analytics dashboard

what you lose

  • Multi-gateway payment fallback routing across Stripe, Authorize.net, and PayPal
  • Turnkey two-way sync with accounting software like QuickBooks and Xero
  • Pre-built PCI-compliant hosted payment pages and vault token migration tools
  • Revenue recognition engine with deferred revenue accounting compliance
  • Turnkey sales tax calculation sync across Avalara and TaxJar

real moats

  • Tokenization lock-in across payment processor vaults
  • Turnkey integrations with legacy accounting ERP systems
  • Historical double-entry ledger audit trail functionality
