same-law-different-platforms
Shopify and PrestaShop sit under exactly the same legal obligation: since June 2025 the European Accessibility Act requires e-commerce services to conform to EN 301 549 / WCAG 2.1 AA, with no micro-enterprise exemption for online shops. What differs is where the defects come from and who can fix them. Shopify concentrates control in a hosted theme layer with Liquid templates and an app ecosystem; PrestaShop gives you self-hosted core templates, a back office, and a marketplace of modules. The compliance work follows those architectures.
⚖️ Same Standard
EN 301 549 incorporating WCAG 2.1 Level AA applies to both. Payment providers and marketplaces increasingly ask merchants of either platform for documented conformance.
🎨 Theme Dominance
On both platforms the active theme controls nearly all rendered HTML — heading hierarchy, focus styles, contrast and form labels are theme decisions, not platform decisions.
🔌 Third-Party Risk
Shopify apps and PrestaShop modules both inject widgets (filters, reviews, popups) with wildly varying accessibility quality. Each needs its own review.
