Marsello
Building a basic e-commerce loyalty widget and points ledger takes a few days. However, Marsello's core strength is bidirectional, real-time sync across physical POS hardware (Lightspeed, Square, Clover) and e-commerce platforms. Maintaining custom API integrations against third-party retail POS devices creates massive developer overhead.
