Investigation service to identify the causes of
revenue discrepancies between GA4 and Shopify,
including duplicate purchase events, missing
parameters, and incorrect event configuration.

Introduction

Small differences between platforms are normal, but large discrepancies often indicate tracking configuration problems.

These issues can affect:

• marketing attribution
• advertising optimization
• conversion reporting
• revenue analysis

This service investigates why GA4 revenue and Shopify revenue differ and identifies the source of the discrepancy.

Revenue differences between Shopify and GA4 often occur due to:

• duplicate purchase events
