FAQ

GA4 Ecommerce Tracking — Frequently Asked Questions

GA4 ecommerce requires a minimum set of events to populate the ecommerce reports: view_item, add_to_cart, begin_checkout, and purchase. For a complete funnel including refunds and product list performance, you should also implement view_item_list, select_item, add_to_wishlist, remove_from_cart, and refund. Each event requires specific parameters — item_id, item_name, price, quantity, and currency at minimum. You can find the complete specification in the GA4 ecommerce event schema.
Yes. Shopify has a native GA4 integration via the Google & YouTube sales channel, but it often produces incomplete or duplicate data. For accurate, complete GA4 ecommerce tracking on Shopify, we implement a custom data layer and GTM container that captures all required events with the correct parameters — including checkout steps that Shopify's native integration frequently misses.
Revenue discrepancies in GA4 ecommerce are almost always caused by one of three things: duplicate purchase events firing multiple times for one transaction, missing the deduplication logic that prevents double-counting, or the purchase event firing before the order is confirmed (on the 'place order' click rather than the confirmation page). A proper implementation includes transaction_id deduplication and fires the purchase event only after backend order confirmation.
Yes — and the most powerful way to do it is via the GA4 BigQuery export. This gives you raw event-level ecommerce data with unlimited retention, which you can query with SQL and connect to Looker Studio for custom revenue dashboards. The direct GA4 connector works for standard reports but is limited by sampling and data retention windows.
