Meta Ads Manager, GA4, and the store backend often report different conversion numbers.
I wouldn’t expect them to match perfectly because they use different tracking and attribution methods. However, if the gap is unusually large, here are the first things I would check.
First, compare the time zones, date ranges, and attribution windows.
Then test the purchase event. Make sure it fires after a completed order and doesn’t fire again when the confirmation page is refreshed.
If both Pixel and Conversions API are active, check whether event deduplication is working correctly. Missing or inconsistent event IDs may cause duplicate conversions.
It’s also worth checking UTMs, redirects, checkout domains, consent settings, and recent website changes. These can create tracking gaps without affecting campaign delivery.
For confirmed orders and revenue, I would use the store backend as the main reference. Meta and GA4 are still useful for understanding attribution and campaign performance, but the numbers will not always match exactly.
