Meta shows $200k, GA4 $150k
- Meta Ads, Google Analytics 4 and Shopify often credit different revenue totals to the same campaign because each platform counts conversions differently. - Google Analytics 4 can use data-driven or last-click attribution, while Meta includes click-through and view-through windows that usually report more conversions. - Shopify says GA4 tracks events; Google and Meta say attribution settings and reporting windows change results.

Meta, Google Analytics 4 and Shopify can all show different revenue numbers for the same campaign, even when they are looking at the same store. (facebook.com) (support.google.com) (help.shopify.com) The split starts with attribution, the rule each platform uses to decide which ad gets credit for a sale. Google Analytics 4 lets admins choose attribution settings for key-event reports, and those settings can change both historical and future reporting. (support.google.com 1) (support.google.com 2) Meta says its Ads Reporting can differ from third-party tools because platforms detect, define and calculate conversions differently. Meta also reports results inside selected attribution windows, including view-based and click-based credit. (facebook.com 1) (facebook.com 2) Google Analytics 4 works differently. Google says its attribution reports can use a data-driven model that distributes credit across touchpoints, while Google Ads conversions based on Analytics key events still use last non-direct click for eligible Google Ads reporting. (support.google.com 1) (support.google.com 2) Shopify adds another layer because it is the commerce system recording actual orders, refunds and checkout events. Shopify says GA4 on Shopify tracks ecommerce events automatically after setup, but merchants still need to configure tags and migrations correctly. (help.shopify.com) (help.shopify.com) The result is that one sale can be counted in more than one place, or missed in one place and counted in another. Meta may claim a purchase after an ad view, GA4 may assign fractional or last-click credit, and Shopify may only show the completed order. (facebook.com) (support.google.com) (help.shopify.com) Tracking setup also changes the totals. Shopify app listings and implementation guides now pitch server-side tracking, first-party data collection and Meta Conversion API connections as ways to recover signals lost to browser limits and privacy rules. (apps.shopify.com) (apps.shopify.com) (apps.shopify.com)) That is why marketers increasingly separate three questions: what the ad platform claims, what the analytics platform attributes, and what the store actually booked. The numbers are related, but they are not designed to be identical. (facebook.com) (support.google.com) (help.shopify.com) When those numbers diverge, the dispute is usually not whether a sale happened. The dispute is which system gets to say it caused it.
