Most "real-time" claims in e-commerce analytics are marketing copy, not an architecture decision. A tool syncs your Shopify and Amazon data once an hour, slaps a lightning bolt icon on the dashboard, and calls it real-time. It isn't. Real-time e-commerce analytics with AI means something specific: data latency measured in minutes, not hours, paired with a system that actually tells you what changed and why, instead of just displaying a number that refreshed slightly faster than before.
