As part of the day to day life at a WooCommerce maintenance agency, we often hear from store owners about frustrating WooCommerce cart or checkout problems:

• A customer says the “Place Order” button didn’t work,
• The cart emptied itself unexpectedly
• The shipping options never loaded or were incorrect
• The payment method disappeared after selection or threw a non-descript error

The customer often didn’t catch the error and the logs didn’t record it either.

Of course, when we test, everything works perfectly, so what’s the deal?

The truth is, cart and checkout problems can be intermittent, browser-specific, device-specific, or even account-specific, making them nearly impossible to replicate in many cases. Without seeing exactly what happened for the customer in real time, you’re left guessing. You could spend 10 hours troubleshooting and pulling out your hair with no resolve.

After experiencing this a few too many times, our Woo agency started using two free tracking tools, Microsoft Clarity and Hotjar, to help us track what is happening on a site and what could be the caused.

1. Why WooCommerce Cart & Checkout Issues Are Tricky

WooCommerce’s cart and checkout pages are highly dynamic. They rely on:

• AJAX calls to update totals and load shipping rates
• Payment gateway APIs for card processing
• Custom JavaScript from themes and plugins
• Session handling from the server hosting environment

One slow API response, JavaScript error, bad custom code snippet or mobile display issue can cause a failed checkout, but it may only happen in specific scenarios (e.g., on iOS Safari, or with a certain shipping method). This is for better or worse, the downside of having complete control over your store and checkout (unlike Shopify checkout). You can create a completely unique customer checkout experience, but all of these variables mentioned can break or impact your checkout, even if they weren’t intended to run on the checkout pages. This is where real-world session recordings can often show you exactly what customers saw when things went wrong.

2. What Microsoft Clarity & Hotjar Bring to the Table

Microsoft Clarity

• 100% free, with unlimited recordings
• Session replays of every visitor
• Heatmaps showing clicks and scrolls
• Rage click and dead click detection
• Browser/device filters for pinpointing issues

We love Clarity for its full coverage and zero cost, perfect for ongoing monitoring a possibly problematic WordPress website.

Hotjar (Free Plan)

• Session recordings (limited daily)
• Heatmaps
• On-page surveys for direct user feedback

Hotjar is perfect for digging further into what likely caused a customer from completing checkout.

Our recommendation:

• Use Clarity for free, comprehensive technical troubleshooting
• Use Hotjar for more specific scenarios or as a secondary review

3. Setting Up Microsoft Clarity for WooCommerce

1. Sign up at clarity.microsoft.com and create a new project
2. Copy the provided tracking code
3. Add it to your WooCommerce site using a plugin like WPCode or you can use the official WordPress plugin
4. Wait for data, you’ll see session replays and heatmaps start populating quickly

4. Setting Up Hotjar for WooCommerce

1. Sign up at hotjar.com for a free account
2. Copy the tracking code
3. Add it to your site the same way as Clarity

5. How We Use These Tools at Inspry to Fix Elusive Checkout and Cart Bugs

When a client reports a hard-to-replicate problem, here’s our process:

1. Filter sessions in Clarity by /checkout or /cart to isolate relevant visits
2. Look for rage clicks or dead clicks on buttons
3. Watch session replays to see exactly what happened before abandonment
4. If needed, review Hotjar secondarily
5. Cross-reference findings with WooCommerce order data and error logs

Example: A recent WooCommerce maintenance client had customers reporting missing payment options. Using Clarity’s device filter, we saw it only happened on iPhones in portrait mode specifically. The culprit? A CSS overflow issue hiding part of the payment section, quickly fixed once identified.

6. Tips for Combining Both Tools

• Use Clarity for more continuous monitoring (since it records every session)
• Use Hotjar sparingly to avoid free plan limits
• Tag important Clarity recordings as “Bug” for developer follow-up
• Check browser/device breakdowns for patterns

7. Privacy and Hidden Data Considerations

Both Clarity and Hotjar typically mask keystrokes and sensitive data. This is to protect user’s privacy which is a good thing, but this does limit what you can see on the cart and checkout. For example, don’t expect to see specific customer’s billing or shipping information at checkout, those will be masked out. Typically though, it gives you enough information to replicate the issue. In addition, keep in mind that using these tracking tools are in fact capturing more speciifc customer data so you may wish to update your privacy policy and consider privacy laws when implementing on a WordPress website.

8. Page Loading and Speed Considerations

Tools like Microsoft Clarity and Hotjar add additional tracking scripts to your website, which can impact page load times and performance metrics such as Core Web Vitals. Similar to adding any marketing script, this minor performance hit is generally acceptable if the data you’re collecting provides meaningful value to your business. That said, we recommend disabling and removing these scripts when they are not actively needed, whether that’s after troubleshooting a checkout issue as in this example, or once a marketing analysis period has ended. Doing so helps keep your site lean and ensures the best possible loading experience for visitors.

Final Thoughts

We’ve seen Microsoft Clarity and Hotjar transform WooCommerce troubleshooting. Instead of guessing why a customer abandoned their cart, you can see exactly what happened and fix the problem fast. Better checkout experiences mean happier customers and more completed orders.
