What is Google Analytics 4?
Google Analytics 4 (GA4) is the latest version of Google’s free analytics tool that helps you understand how visitors use your website. Unlike the older Universal Analytics, GA4 tracks events instead of just pageviews, giving you deeper insights into customer behavior.
With GA4, you can see where users come from, how they interact with your WHMCS site, and what actions lead to conversions. It is designed for modern businesses with better reporting, AI-powered insights, and seamless integration with Google Ads. For WHMCS users, GA4 makes it easier to track the entire sales journey.
Why Use Google Analytics 4 with WHMCS?
- Track Complete Customer Journey: Monitor how visitors move from browsing to purchase on your WHMCS site.

- Cross-Device Tracking: See how users interact with your WHMCS site across mobile, tablet, and desktop.
- Future-Proof Analytics: GA4 is the new standard, replacing Universal Analytics for modern data tracking.
Prerequisites Before Google Analytics-WHMCS Integration
Before you connect WHMCS and Google Analytics 4, make sure you have the following in place:
- Google Analytics 4 Property: Create and set up a GA4 property in your Google Analytics account.
- Measurement ID: Copy the GA4 Measurement ID from your Data Stream settings.
- WHMCS Admin Access: Log in with admin rights to edit theme or template files.
- Template File Access: Ability to modify header.tpl or footer.tpl in your WHMCS theme.

How to Integrate Google Analytics and WHMCS?
Step 1: Create a Google Analytics Account
- Go to Google Analytics.
- Sign in with your Google account (or create one if you don’t have it).
- In the Admin panel, click Create Account.
- Give your account a name (e.g., “My Hosting Business”) and configure data-sharing settings as needed.
Step 2: Set Up a GA4 Property
- After creating an account, click Create Property.
- Enter your Property Name (e.g., “WHMCS Site”).
- Choose your reporting time zone and currency.
- Click Next and provide basic business details (industry and size).
- Finish setup to generate your GA4 property.
Step 3: Create a Data Stream
- Inside your new GA4 property, go to Data Streams.
- Choose Web and enter your WHMCS website URL.
- Give the stream a name (e.g., “WHMCS Stream”).
Step 4: Copy the GA4 Tracking Code
- Once your property is ready, Google Analytics will provide a global site tag (gtag.js) code.
- Go to Admin → Data Streams → Web Stream Details.
- Under Tagging Instructions, select Install manually.
Step 5: Insert Tracking Code in WHMCS Template
- Now you need to add the GA4 script into your WHMCS site so it loads on every page.
- Access your WHMCS files via cPanel, FTP, or File Manager.
- Navigate to the template folder:
- whmcs/templates/{your-template-name}/
- Open header.tpl (recommended) or footer.tpl file.
- Paste the GA4 code snippet just before the closing </head> tag in header.tpl.
- Save and re-upload the file if needed.
Step 6: Clear WHMCS Cache
- Sometimes WHMCS caches template files.
- Go to Utilities → System → System Cleanup in your WHMCS admin.
- Click on Empty Template Cache.
This ensures your new tracking code is active right away.
Step 7: Verify Tracking Installation
- After adding the script, check if GA4 is receiving data:
- Go to your GA4 dashboard → Realtime Reports.
- Open your WHMCS site in another browser tab.
- If integration is successful, you’ll see yourself as an active user in the Realtime view.
Alternatively, you can use the Google Tag Assistant Chrome extension to test.
That’s it! You’ve now connected WHMCS and Google Analytics 4.
Enabling Enhanced Measurement in Google Analytics for WHMCS
This is an optional step if you want to enable enhanced measurement in Google Analytics and WHMCS integration:
GA4 has built-in tracking for events like scrolls, outbound link clicks, file downloads, and site searches.
- In GA4, go to Admin → Data Streams → Web Stream Details.
- Scroll down to Enhanced Measurement and toggle it ON.
This allows automatic event tracking without additional code.
Setting Up Converstion Tracking for WHMCS in Google Analytics
If you want to make the most out of your WHMCS and Google Analytics integration, you should track the key actions, like:
- Client Registration → Track when a user creates a new account.
- Product Purchase/Order Completion → Add event code on the checkout success page.
- Invoice Payment → Track completed transactions.
For example, to track a purchase event, add this after your GA4 code on the order confirmation page:
<script>
gtag('event', 'purchase', {
transaction_id: 'ORDER_ID',
value: ORDER_AMOUNT,
currency: 'USD'
});
</script>Replace placeholders with WHMCS dynamic variables.

Advanced Google Analytics Integration in WHMCS
Once you have the basic GA4 code running, you can take tracking to the next level with advanced methods. These will give you deeper insights into how clients use your WHMCS site and where your revenue comes from.
1. Use Google Tag Manager (GTM)
Instead of placing GA4 code directly in templates, you can use Google Tag Manager:
- Create a free GTM account at tagmanager.google.com.
- Add the GTM container code in your WHMCS header.tpl file.
- Configure GA4 tags inside GTM (page views, events, conversions).
This makes it easier to add or update tracking without editing WHMCS files again.
2. Track Checkout Funnel Steps
WHMCS has multiple steps in the checkout process — from cart → checkout → payment → order confirmation.
Add custom GA4 events at each step to see where customers drop off.
Example event code for cart page:
<script>
gtag('event', 'view_cart', {
currency: 'USD',
value: CART_TOTAL
});
</script>Replace CART_TOTAL with WHMCS dynamic variables.
3. Track Registrations and Logins
- Understanding user sign-ups is critical for hosting businesses.
- Place a sign_up event on the client registration success page.
- Place a login event when users log in successfully.
<script>
gtag('event', 'sign_up', {
method: 'WHMCS Registration'
});
</script>4. Connect GA4 with Google Ads
If you run ads, linking GA4 with Google Ads gives better reporting:
- In GA4, go to Admin → Product Links → Google Ads.
- Connect your Ads account.
- Import conversion events from GA4 into Ads for smarter bidding and remarketing.
5. Create Custom Reports in GA4
Use Explorations in GA4 to build reports tailored for WHMCS.
Example: Track new vs. returning customers, revenue per service, or drop-offs during checkout.
Combine these insights with your sales data for stronger decisions.
