BigCommerce web design: Stencil-native, conversion-built, mobile-first

BigCommerce web design is a different discipline than Shopify or Magento design. Stencil's template hierarchy, Page Builder behaviour, and BC's product page model each create design opportunities and design constraints. Below is what our design team ships on every BC engagement and how the work translates to revenue.

BigCommerce design considerations vs Shopify and Magento

Our 4-phase BigCommerce design process

1. Conversion audit and UX brief

Heatmaps, session recordings, GA4 funnel analysis. Identify drop-off points and PLP/PDP friction. Output is a conversion brief that drives every design decision.

2. Wireframes and prototypes

Figma wireframes for homepage, PLP, PDP, cart, checkout. Mobile-first. Validated against conversion brief and stakeholder input. Interactive prototype for stakeholder sign-off.

3. Stencil theme build

Custom Stencil theme built from wireframes. Handlebars templates, SCSS architecture, lazy-loaded sections, Core Web Vitals optimised. Integrated with BC Page Builder where editorial flexibility matters.

4. QA, launch, and iteration

Cross-device QA, accessibility audit (WCAG 2.1 AA), Lighthouse baseline. Post-launch we run a 30-day A/B testing sprint on the top 3 conversion points identified in the audit.
