CHECKS RUN DAILY · ALERTS THE DAY IT BREAKS

Your store says
100 orders.
GA4 says 82.

Somewhere between the sale and your analytics, orders go missing. TrackGap tells you which ones, what they were worth, and whether it is actually broken — or just someone declining cookies.

Shopify knows what sold.
GA4 knows what it saw.

TrackGap sits between those two numbers and shows you exactly where they stopped matching — and which part of the gap is worth fixing.

One screen. The whole answer.

The big number is the share of orders that never reached your analytics. Under it, the same gap split by cause — because half of it is usually consent, and that part you cannot fix.

The revenue figure is the sum of the missing orders as your store recorded them — not an estimate from ad spend you typed in.

It is not just you

Posts from the Shopify Community forum. There are over a hundred threads like these.

Each week is so different — about 10 – 20% of orders are missing. Asked Shopify support but they say it's a problem with Google.

community.shopify.com

Last year we sold 348 of a specific product, but in GA4 it's only saying that we sold 54.

Actual orders: 2,961. Thank-you page views in GA4: 1,129. That's a gap of nearly 3×.

How it works

Install it, connect GA4, done. Nothing goes into your theme.

STEP 01

Reads your orders

Straight from Shopify, server-side. Adblockers and consent banners cannot touch this one.

STEP 02

Checks what arrived

Pulls the transactions GA4 actually recorded and matches them by order ID, one at a time.

STEP 03

Works out why

Broken tag, declined consent, duplicate events, or a value sent without shipping. These are very different problems.

STEP 04

Sends them back

Where there is consent and an identifier, the missing conversion goes back to GA4 with its original source. Where there is not, we say so instead.

Setting it up takes minutes
1
Install from Shopify Approve order and pixel permissions in the standard flow.

Official Shopify and Google APIs. No theme code to paste or maintain.

Not another audit tool

Audit tools load your site and check whether the tag fires. That is useful — and it is not the same question.

If you need to know whether your tracking plan is correctly implemented, use an audit tool. If you need to know whether yesterday's orders arrived — that is this.

Why this exists

I run measurement for around eighty e-commerce stores. The same thing kept happening: a client's numbers stopped matching, and finding out why meant exporting orders, pulling GA4 transactions and diffing them in a spreadsheet — every time, by hand.

One store had been sending every purchase to GA4 twice since April. Revenue looked 13,000 € higher than it was, and nobody noticed for four months. Another had a conversion action in Google Ads that recorded nothing for 38 days straight while the store kept selling.

Neither was hard to find once you knew to look. That is the whole point of this app: it looks, every day, so you do not have to.

Rather not fix it yourself?

TrackGap finds the problem. Fixing it usually means going into GTM, consent mode or server-side tagging — which is what I do for a living.

Shopify tracking gaps, explained

The questions merchants ask before installing.

Why do Shopify orders and GA4 transactions not match?

Common causes include declined analytics consent, blocked or broken purchase tags, duplicate events, processing delays, and order values sent without shipping or tax. TrackGap matches orders by ID so these causes can be separated.

Does TrackGap modify my Shopify theme?

No. TrackGap uses official Shopify APIs and a Shopify web pixel extension. There is no theme code for the merchant to install or maintain.

Can TrackGap recover missing GA4 conversions?

Yes, when the visitor granted the required consent and a valid GA4 client identifier is available. TrackGap does not send conversions when consent is declined or cannot be demonstrated.

What customer data does TrackGap store?

TrackGap does not request customer names, email addresses, postal addresses, phone numbers, or payment details. It uses order IDs, values, timestamps, traffic sources, and pseudonymous analytics identifiers needed for reconciliation.
