Experienced GA4/Stape/GTM/WooCommerce Consultant

We are looking for an experienced Google Analytics 4 (GA4), Google Tag Manager (GTM), Stape.io, and WooCommerce Tracking Consultant to audit, overhaul, and fix a series of critical data discrepancies on our e-commerce platform. Currently, server-side and client-side data mismatch issues are causing severely inflated transaction values (e.g., a £0.19 test basket recording as £190,000) and massively distorted negative revenue figures in our refund reporting. We need an expert to completely clean up our data layer, fix our tag triggers, and ensure our Consent Mode is fully compliant and stable. Key Issues to Resolve Currency/Decimal Inflation: Investigate and resolve a critical issue where basket values are being multiplied/scaled incorrectly (e.g., missing decimal points converting £0.19 into 190,000 in GA4). Clean up the resulting historical distortion in refund data. Consent Mode V2 Configuration: Fix the current Consent Mode setup (currently set to automatic within GTM) to ensure proper, compliant, and conditional behavioral modeling. Duplicate Page Views: Eliminate duplicate page view tracking that occurs immediately after a user accepts the cookie banner. Broken 'Add to Cart' Triggers: Troubleshoot and fix the data layer event push for 'Add to Cart' actions, which is currently failing. E-commerce Object Triggers: Repair the broken e-commerce object triggers to ensure GA4 purchase/item schemas are populated accurately. Required Skills & Experience Deep WooCommerce Expertise: Complete understanding of the WooCommerce data layer, common tracking plugins, and how WordPress handles e-commerce hooks. Advanced GTM & Server-Side Tracking (Stape.io): Proven experience managing hybrid tagging environments, routing server-side events via Stape, and debugging server-to-client discrepancies. GA4 E-commerce Architecture: Expert knowledge of GA4 schemas, currency parameters, refund tracking, and cleaning up historical data anomalies. Consent Mode Mastery: Hands-on experience configuring advanced Google Consent Mode V2 alongside popular Cookie Consent platforms (CMP). Scope of Work Initial Audit: Review the existing client-side GTM container, Stape.io server-side container, and WooCommerce data layer setup. Immediate Fixes: Address the decimal inflation issue, duplicate page views, and broken e-commerce triggers as a priority. Validation & Testing: Run end-to-end purchasing tests to verify that net revenue, taxes, shipping, and item values match exactly between WooCommerce and GA4. Documentation: Provide a brief summary of the changes made so our internal team is aligned moving forward.
