Frequently Asked Questions

What aspects of an ecommerce site should be tested before a major sale?
Before peak events like Black Friday or product launches, you should test: checkout and payment flows under load, inventory and stock management accuracy, basket and discount code logic, search and filtering behaviour, and page load performance. We run load tests that simulate 10x your normal traffic to find bottlenecks before they cost you sales.
Can you test Shopify, Magento, or custom ecommerce platforms?
Yes. We test across all major platforms including Shopify, Magento, WooCommerce, and bespoke ecommerce builds. Our approach is platform-agnostic and starts with your user journeys, not the platform.
Do you test third-party integrations like payment providers and shipping APIs?
Yes. We test end-to-end integrations including payment gateways (Stripe, PayPal, Adyen), shipping providers, loyalty programmes, and marketing automation hooks. Integration failures are one of the most common causes of checkout abandonment.
How do you check the checkout conversion funnel?
We test each step of the funnel from product page through basket, guest and registered checkout, payment, and confirmation. We flag UI friction, confusing error messages, and missing validation that cause drop-off, as well as technical defects.
