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.
