Overview

BigCommerce storefronts, engineered honestly

EcomLabs builds and customizes BigCommerce stores end to end. We work in Stencil themes, tune PDP and PLP layouts, refine category UX and make sure the storefront stays fast as your catalog grows.

We're engineers first, so we're upfront about what BigCommerce does well and where it constrains you — especially around checkout. You get a store that fits the platform's strengths instead of fighting them.

Built on Stencil
Real theme development in Stencil — not just template tweaks — so your storefront is structured, maintainable and yours to extend.
Catalog-ready UX
PDP, PLP and category navigation designed to handle large, faceted catalogs without slowing shoppers down.
Honest about limits
We tell you upfront where BigCommerce's checkout and platform constraints apply, so there are no surprises mid-project.

Process

How we deliver

  1. Discover & scope

    We map your catalog, goals and constraints, flag the platform limitations early and agree a scope with clear milestones.

  2. Design & build

    We build the storefront in Stencil with clean, documented code, focusing on PDP, PLP and category experience.

  3. Launch & QA

    Cross-device QA, performance and accessibility checks, then a controlled launch with monitoring.

  4. Support & iterate

    Post-launch support and a roadmap of improvements based on real store data.

FAQ

BigCommerce Development

Can you fully customize the BigCommerce checkout?
Partly. BigCommerce's hosted checkout is more constrained than platforms like Shopify Plus. We customize what the platform allows — styling, Optimized One-Page Checkout options and available APIs — and we're clear upfront about what isn't possible.
Do you build themes from scratch or customize existing ones?
Both. We build custom Stencil themes and also extend or clean up existing ones, depending on your budget, timeline and how far the current theme can be taken.
Will my team be able to maintain the store?
Yes. We write structured, documented Stencil code and set up the theme so your team can manage everyday content and catalog changes without touching core templates.
