Broken cart & checkout flows
Verify add-to-cart, checkout, and payment actually complete end to end — the exact steps an uptime ping never touches.
A broken checkout doesn't show up as downtime. It shows up as lost revenue.
NorthDuty watches your store like a QA engineer: it walks the real buying journey — add to cart, checkout, payment, confirmation — and flags broken buttons, blank pages, JS errors, and visual regressions that uptime checks never catch. Every silent failure between a customer and the Buy button becomes an alert to you, not an abandoned cart.
Your uptime monitor says the store is up. Your customers say they can't pay.
The product page returns a 200, so the uptime tool stays green — but a theme update hid the add-to-cart button, a payment script failed to load, or a discount field throws an error on mobile. Nothing is technically 'down', and yet orders quietly stop. By the time you spot the dip in sales, you've already lost a day of revenue.
Stores break in ways uptime checks can't see: a third-party app conflict, an expired script, a layout regression after a theme change, or a checkout step that fails only on certain devices. NorthDuty runs the actual purchase journey on a schedule and verifies it completes — so a broken funnel surfaces as an alert in minutes, not as a confused email from a customer who couldn't check out.
What NorthDuty catches across your storefront
The failures that cost you orders almost always pass an uptime check.
Failed payment & third-party scripts
Catch a payment widget, tag, or app that silently fails to load or throws a JS error and quietly blocks purchases.
Theme & app-update regressions
Visual diffing flags missing buttons, broken layouts, and hidden CTAs the moment a theme edit or app install changes the page.
Peak-season & promo readiness
Going into a sale or Black Friday, confirm the funnel still works under your new promo, banner, and discount-code setup before traffic hits.
Why ecommerce teams run NorthDuty
Stop finding out about a broken funnel from a drop in your sales dashboard.
- Monitor the full buying journey — product, cart, checkout, payment, confirmation — not just whether a page loads
- Catch broken add-to-cart and checkout steps that uptime tools miss, before customers abandon
- Get alerted the instant a theme edit, app, or script breaks a key page or flow
- Protect mobile checkout specifically, where many silent failures only appear on certain devices
- Validate the store before a promo, launch, or peak-season traffic spike
- Watch product pages and PDP templates for blank pages, missing prices, and broken images
How to roll NorthDuty out on your store
Start with the one journey that makes you money, then expand coverage.
1
Add your checkout journey first
Record the path that drives revenue: product page, add to cart, checkout, and payment confirmation. This is the flow you can't afford to have break.
2
Add product & category templates
Monitor your highest-traffic PDP and collection templates for blank pages, missing prices, broken images, and JS errors.
3
Wire alerts to where you work
Route alerts to email or Slack so a broken funnel becomes a ticket in minutes — before it becomes a day of lost orders.
4
Lock it down before every sale
Re-run the checks after each theme change, app install, or promo setup, and especially in the run-up to peak-season traffic.

Answers to common questions about this website monitoring use case.
How is this different from the uptime monitoring I already have?
Uptime tools confirm a page responds. NorthDuty verifies customers can actually buy — that add-to-cart works, checkout completes, payment scripts load, and nothing broke visually since your last theme or app change. Most lost-order incidents pass an uptime check.
Does it work with Shopify, WooCommerce, and other platforms?
Yes. NorthDuty monitors the live store in a real browser, so it works regardless of platform — Shopify, WooCommerce, Magento, BigCommerce, or a custom build. It watches the pages and journeys your customers actually use.
Can it catch problems that only happen on mobile?
Yes. Many checkout failures only appear on certain devices or viewports. NorthDuty runs journey and visual checks that surface mobile-specific breaks like hidden buttons or overlapping fields.
What should I monitor first for my store?
Start with the single journey closest to revenue: product page to add-to-cart to checkout to payment. Then add your top product and category templates, and any pages tied to promotions.
Can it help me prepare for Black Friday or a big sale?
Yes. Before peak traffic, NorthDuty validates that your checkout, discount codes, and promo pages still work after the changes you made to prepare — so you find issues during setup, not during your busiest sales hours.
