Going headless silently breaks conversion tracking and marketing-source data on Shopify Plus. Shopwright restores full, deduplicated attribution end to end — a one-time fix you own in your own codebase, not another monthly SaaS tax.
It's not a tagging mistake you can fix in settings. Your storefront and Shopify's checkout are separate surfaces that don't share cookies, so attribution never makes the hand-off. The tell: it affects 100% of orders, not intermittently. That's structural.
Purchases land as (not set) / Direct / Unassigned in GA4 and Meta. Pixels under-count, so the ad platforms optimize toward the wrong people — spending your budget against bad data.
Every order's utm_source / utm_campaign arrives empty inside Shopify itself. You can't see which campaign or ad actually drove each sale, so you can't cut losers or scale winners.
When the platforms optimize against incomplete data, a slice of every dollar is spent reaching the wrong people. Move the slider to see the rough scale on your spend.
Industry post-iOS signal loss commonly runs in the low double digits. This uses a conservative 15% illustrative mis-optimization rate — your actual figure comes out of the audit.
Most Shopify apps assume a Liquid theme and silently break on a custom front-end — the widget loads in the admin but never renders for your customers. The same engineering that fixes attribution keeps the rest of your stack working, available as an ongoing retainer.
Subscriptions (Recharge, Appstle), upsell engines (e.g. Rebuy), reviews and loyalty — wired into your headless storefront so they actually render and convert, not just work in the admin.
Core Web Vitals and checkout speed for a Hydrogen / custom front-end — plus the technical SEO headless quietly breaks: SSR, structured data, meta tags and crawlability, so Google sees what your customers see.
Theme updates, new ad channels, and platform changes quietly re-break attribution. Ongoing maintenance keeps it solid so you're never flying blind again.
Start with a sharp, fixed-scope fix — no open-ended hours. The retainer and advisory are there when you want them, never required.
Worth it? A full headless rebuild runs $80K+. Rented tracking SaaS like Elevar or Littledata bills $150–500/mo — forever. The fix is one-time, and you own it in your own codebase.
I built and maintain this exact pipeline — both conversion events and UTM capture — for an active Shopify Plus subscription-box brand, on a recurring retainer.
The fix is a documented, repeatable module. That's why it's quoted as fixed scope instead of open-ended hours — you know the price up front.
The work lives in your codebase. No perpetual per-month tracking tax, no vendor lock-in, no black box you can never leave.
A 20-minute look tells you whether attribution is broken and roughly what it's costing. No deck — a straight read on your setup.
