GA4 Ecommerce Purchase Data Falling Short Compared to WooCommerce

Issue: My GTM and GA4 setup for WooCommerce captures only about half the purchase count and revenue compared to WooCommerce’s own reports. Why might this discrepancy occur, and how can it be fixed?

hey charile, seems like ga4 triggers are not firing sometmes properly after checkout. check your tag firing order and data layer setup. misconfiguratoin may be causing the missng transactions.

Hey Charlie31, I’ve been digging into a similar issue and had to wonder if there’s more going on than just tag misfires. For instance, could there be differences in how GA4 and WooCommerce attribute the purchase event? I’ve noticed that sometimes, settings like session timeout or even how refunds and cancellations are handled can create a gap between GA4 and backend reports. Have you had a chance to review the event sequencing in GTM closely to see if perhaps there’s a delay or a missing parameter being passed at purchase completion? I also wonder if the issue might be linked to timing differences and the way GA4 processes transactions as opposed to WooCommerce’s immediate captures. What’s your current setup for order confirmation? It might make sense to do a few test transactions while closely watching the network requests so you can pinpoint if any steps are being skipped or delayed. Keen to hear if you’ve seen similar patterns anywhere else or if any other WooCommerce users have insights into this kind of situation.

In my experience, similar discrepancies typically result from timing issues within the checkout process. Even when the tracking setup appears correct, subtle delays can prevent GA4 from recording every transaction accurately. I encountered this issue and resolved it by implementing a slightly delayed event trigger in GTM to ensure that the data layer had enough time to update. Additionally, verifying the consistency of currency formatting and tax information between the systems helped address some of the differences, making the GA4 data more aligned with WooCommerce reports.
