Google Analytics 4 is not enough for ecommerce brands that want to make confident, revenue-driving decisions. It tracks traffic and sessions well. But it cannot show you why your ROAS dropped last Tuesday, which customer segments are actually profitable, or what your revenue will look like in 60 days. Those gaps cost real money.

GA4 was designed as a web analytics tool. Ecommerce is an operations problem. You need to know inventory exposure, contribution margin by channel, LTV by cohort, and churn risk by segment. GA4 gives you none of that, and patching it with exports, pivot tables, and Looker workarounds burns 10+ hours a week that should go toward growing the business.
