Shopflo

Building a custom checkout UI and cart drawer with AI takes under two weeks. However, Shopflo's primary moat lies in its cross-merchant address auto-fill network via phone OTP and deep local payment gateway failover orchestration. Rebuilding the frontend is trivial, but matching their conversion lift network is not.

you can rebuild

  • Slide-out cart drawer with dynamic progress bar
  • Post-purchase upsells and cross-sell modals
  • Custom checkout UI theme customizer
  • Basic discount code validation and cart application
  • Order confirmation page widgets and order tracking UI

what you lose

  • Cross-merchant network of pre-saved shopper addresses indexed by mobile OTP
  • Automated payment gateway failover and payment routing logic
