Your Meta says 40 purchases. GA4 says 28. Your store says 19. Which number do you trust when you decide where to put the next $1,000? I'm a conversion tracking engineer. I find which number is lying, fix it at the source and prove the fix against your real orders and leads. The gap is rarely a rounding error. Browser-only pixels, iOS, ad blockers and duplicate tags drop or double count events. The ad platforms then optimize on bad data. I learned this on my own Shopify and WooCommerce stores, where the tracking had to work because it was my money. I built Meta CAPI with event_id deduplication there before I did it for clients. Here's what I fix and build. - Meta Pixel + Conversions API with deduplication, so each sale counts once - GA4 that matches your backend, with clean key events and purchase values - Google Ads conversions and Enhanced Conversions, plus Microsoft Ads - Google Tag Manager cleanup and server-side tagging - CRM and offline conversions: HubSpot, GoHighLevel and others send real sales and qualified leads back to Google Ads and Meta - Shopify, WooCommerce, Magento and custom checkouts - Mobile app attribution: Adjust, AppsFlyer, RevenueCat, iOS SKAN - Consent setup that keeps the signal you're allowed to keep - AI traffic: ChatGPT, Perplexity and Gemini visitors pulled out of Direct into their own channel Every job starts read-only. You get a short audit with your own numbers and a fixed price, and nothing changes until you approve it. Every fix is tested with real orders or test submits, with before and after numbers.
