Conversion tracking silently breaks across storefront integrations, leaving agencies with no source of truth and week-long blind debugging

Summary

Agencies and store owners routinely lose AddToCart and Purchase events while PageView/ViewContent still fire — the platform's own test events look fine, the third-party analytics tool says otherwise, and old pixel IDs plus hand-pasted tracking code buried in theme.liquid quietly conflict with the native sales-channel integration. The result is over a week of guesswork: creating new pixels, disabling integrations, second-guessing which tool is lying, with no authoritative view of what is actually firing on the live storefront and no way to see when it stopped working. Nobody can tell the client why reported revenue doesn't match ad-platform numbers, so reporting and retainer conversations collapse into 'we're still investigating.' Existing tools each report only their own silo — platform admin, pixel events manager, tag manager, analytics — and none cross-check them against the live storefront to flag missing or duplicated events. This is unsolved for the multi-client, multi-platform agency case: there is no monitoring layer that verifies pixel/tag/event integrity per client store and surfaces a plain-language, client-ready finding.
