Shopify is a great platform. It removes enormous amounts of technical complexity. But that simplicity comes with constraints, and those constraints create specific, repeatable UX problems that cost Shopify stores real money every day.
The Dawn theme, which powers a majority of Shopify stores, has known issues with product variant selectors when multiple options are combined. Customers click a color, the size options update, but the selected size appears available when it isn't. Add to cart. Error. Frustration. Exit.
Since Shopify introduced Checkout Extensibility, the checkout flow has become harder to customize without Shopify Plus. Standard stores are locked into a specific checkout structure that may not match how your customers want to buy. And third-party apps installed to compensate for this often inject JavaScript that conflicts with each other, slowing the page and creating errors that only appear for specific browser and device combinations.
For European stores, these problems multiply. iDEAL is used in 60-65% of all Dutch online transactions, but the default Shopify checkout buries it under credit card options. GDPR cookie consent banners layer on top of product pages and interfere with session recordings. VAT-inclusive pricing display is legally required in the EU but Shopify's default pricing behavior was built for US markets.
These aren't abstract issues. They are specific, findable, fixable problems that show up in session recordings, in GA4 funnel data, and in checkout abandonment rates.
