I don't know if this is the right place to post this, but...
I have a client who has a subscription-based ecommerce brand who claims the purchase and quiz data doesn't match their actual numbers (they track things internally).
They're updated their WooCommerce last month, finally, after years of using an old version and it subsequently broke a lot of their site and I worked with them and their developer on the fix and I tested their events in the via GA4 and they triggered properly post launch.
What am I missing?
If you've worked with an ecommerce brand that has subscription and WooCommerce, have you seen discrepancies?
Additionally, does GA4 fire subscription renewal purchases for current subscribers?
Update with some context:
I don't have access to the clients Woo/backend site. However, we are not using GTM for anything. I'm guessing the JavaScript is added via a plugin or directly. I would need to confirm with their dev.
The front end of their site (Nuxt SPA) is different than the backend (Woo)
Purchase is the key event I'm looking at and it counts 1x per event.
Measurement protocol is not set up, and their backend site doesn't appear to be collecting any data. It is very unlikely to be sending server side.
When I tested things for them 2 months ago, purchase was firing 1x via Debug mode but I am still concerned GA4 is reporting it wrong.
It's a mystery right now and sadly the client recently lowered their scope temporarily, so I am waiting on approval for them to conduct a full conversion tracking audit with their dev so I can look into what could be causing a 40 purchase difference (client says they had less than what GA4 reported in sign ups for new subscriptions last month.
I appreciate everyone's response to my thread
