Your WooCommerce Currency Switcher Is Corrupting Every Revenue Report

WooCommerce multi-currency plugins create silent revenue data corruption across every tracking platform. Currency switchers like WOOCS, Aelia, and WooPayments each handle currency differently in tracking events, causing GA4 to receive EUR while Facebook CAPI gets USD for the same purchase. GA4 compounds the problem by reconverting currencies at current exchange rates every time a report loads, creating phantom revenue fluctuations. 70% of eCommerce stores already have broken tracking, and adding multi-currency support makes it worse because most tracking plugins can’t distinguish between base currency, display currency, and settlement currency. Server-side tracking that accesses the WooCommerce order object directly is the only architecture that can send the correct currency to each platform independently.
