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.
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
