- Automated Klaviyo and Attentive custom profile property sync
- Tokenized 1-click cart pre-fill link generation
- One-time purchase to subscription upgrade links
- Replenishment conversion reporting dashboard
what you lose
- Pre-packaged Klaviyo email and SMS flow templates
- Cross-merchant benchmark data for default repurchase intervals
- Turnkey integrations with major Shopify subscription apps (Recharge, Skio, Loop)
- Hosted dynamic reorder portal widgets
- Automated cross-sell SKU recommendation engine

Sticky.io
Basic recurring billing logic using Stripe is easy to build with AI, but Sticky.io handles multi-MID processing, cascade routing, card account updates, and PCI vaulting. Migrating vaulted payment tokens away from a custom setup when gateways decline transactions is a compliance nightmare.
you can rebuild
- Basic subscriber portal for pause, skip, and swap
- Subscription catalog and discount code management
- Recurring order schedule generation
- Basic email notifications for upcoming rebills
- Standard churn reporting and dashboard metrics
what you lose
- Multi-MID and gateway cascade routing engine
- PCI Level 1 compliant token vaulting outside of standard gateways
- Visa/Mastercard Account Updater (VAU/ABU) integration for expired cards
- Sophisticated decline recycling and smart dunning sequences
- Built-in chargeback protection software integrations
real moats
- PCI-DSS compliant payment token vault across multiple gateways
- Pre-built integrations with merchant processing gateways and fraud tools
- Historical transaction routing data for decline optimization
