Which ecommerce analytics tool has the fastest setup time?

Tools that connect through native app-store integrations, like Trivas on Shopify, go live the same day. Warehouse-first platforms or tools that need custom attribution modeling, like Northbeam or some Polar Analytics configurations, typically take one to four weeks. That's the honest answer to which ecommerce analytics tool has the fastest setup time, and the variable that decides it isn't brand reputation or feature count.
