Open any e-commerce analytics tool's homepage and you'll see the words "real-time" somewhere above the fold. Almost none of them mean it. Amazon data syncs every 4 to 6 hours. Meta and Google ad spend lags by 1 to 3 hours before attribution settles. GA4 won't give you a finished number for 24 to 48 hours. Call that whatever you want, but it isn't real-time.
