Frequently asked questions

Why does Meta report more revenue than Shopify?
Meta uses view-through and click attribution windows that can credit the same sale multiple times across campaigns. A 7-day click + 1-day view window will almost always show higher revenue than Shopify's order count.
Which platform should I trust for true revenue?
Shopify is always the ground truth for actual orders placed and revenue received. Meta and GA4 show attributed revenue — their job is campaign measurement, not accounting.
Why does GA4 show less revenue than Shopify?
GA4 relies on browser-side tracking which is blocked by iOS privacy, ad blockers, and users who close the page before the tracking fires. Server-side CAPI typically recovers 20–40% of this lost signal.
