When Shopify, Google Ads, Meta, GA4, or your CRM disagree, the expensive mistake is hiring someone to “fix tracking” before the actual break is defined. I help ecommerce brands and agencies isolate mismatched conversion events and turn the issue into a repair-ready proof packet. Best fit: • Shopify purchases not matching Google Ads • Meta Purchase events missing, duplicated, or not attributing • GA4 / GTM ecommerce events firing inconsistently • Agencies needing a client-safe tracking issue summary • Founders who need to know whether paid media data is safe to trust Send me the disputed conversion path. I’ll tell you whether it is safe, broken, repair-ready or inconclusive.
