BigCommerce Storefront Design & Front-End

BigCommerce web design that is built to convert, engineered to load fast.

A storefront that looks good but sells slowly is costing you orders every day. We are a senior BigCommerce design team and BigCommerce partner that pairs conversion-led design with real front-end engineering on Stencil or headless with Catalyst, so the same team that designs your store also builds it, accurate and fast. Sixteen years in, with no junior bench and no handoffs.

Why brands come to us

When the storefront looks fine but the numbers say otherwise.

Most BigCommerce stores leak revenue in the same places: a homepage that does not earn the scroll, product pages that bury the reasons to buy, and a front-end that crawls on mobile. We are the BigCommerce design team brands call when the stock-theme phase is over and the storefront has to pull its weight. We pair conversion-led design with senior front-end engineering, so the design ships, loads fast, and moves the numbers.

What our BigCommerce design team builds

Storefront design and front-end engineering, from a single template to a full custom theme.

Whatever the store needs, the same senior team handles design and build end to end on Stencil or Catalyst. Every engagement is scoped to your roadmap, not a fixed package.

Two ways to build

Stencil theme or Catalyst headless?

BigCommerce is open SaaS, so the storefront is yours to shape either way, with no platform transaction fees on the plan side. The real choice is design freedom against build effort. A Stencil theme moves fast and stays easy to edit; a headless front-end on Catalyst trades that simplicity for total control. We design conversion-led storefronts on both, and recommend headless only when the experience genuinely calls for it.

Stencil (built-in)

Stencil is BigCommerce's native theme engine, built on Handlebars templates. We design and build custom Stencil themes tuned for conversion and Core Web Vitals, then wire Makeswift so your team can edit pages with no code. You get a distinct, fast storefront on the platform's own rendering, which keeps the build simpler to launch and easier to maintain. Design freedom is high across layout, components, and merchandising; the one boundary is that the front-end still renders the BigCommerce way.

Best when
  • You want a custom storefront on a faster timeline
  • Marketing needs no-code editing with Makeswift
  • Conversion and Core Web Vitals are the priority
Catalyst (headless)

Catalyst is BigCommerce's React and Next.js headless framework. We design and engineer the front-end as its own application, pulling catalog and checkout through the Storefront APIs, which hands you total control over the experience, the animation, and the routing. The tradeoff is more build effort and a front-end your team maintains as code rather than editing in a theme. We reach for it when the storefront design needs to go beyond what a Stencil theme can render.

Best when
  • The experience needs total front-end control
  • You want a React and Next.js storefront
  • Your team can own a headless front-end as code

We pair the design with the right build in a design and engineering consult.

Why IWD

Design and front-end from the same senior team, kickoff to launch and beyond.

Most BigCommerce redesigns go sideways for one of two reasons: the design is gorgeous but the front-end build cannot match it, or the agency vanishes once the store goes live. We built IWD to do the opposite.

  • Design and engineering, one team

    What we design is what we ship. Designers and front-end engineers work side by side on Stencil and Catalyst, so your storefront lands accurate and fast, with nothing lost between the mockup and the live store.

  • Built to convert, engineered to load fast

    Every design decision answers to two questions: does it help the customer buy, and does it keep the store fast? We design for Core Web Vitals and conversion together, because beauty that loads slowly does not sell.

  • Senior team, no junior bench

    You work with the people doing the work. We do not pass your BigCommerce storefront to a training program and disappear once it goes live.

  • We build, then we stay

    Most clients keep us on after launch for conversion testing, new features, and growth. The team that designed it is the team that keeps improving it.

How we work

A clear path from audit to a storefront that earns its keep.

01

Audit

We review your current storefront, analytics, and funnel to map where the design is leaking conversions and which templates are worth redesigning first.

02

Design

Wireframes and high-fidelity design for the templates that matter, shaped around your brand and your buyers. You see the direction before any code is written.

03

Build

Front-end engineering in two-week sprints with weekly demos. The same senior team ships the design on Stencil or Catalyst, accurate, fast, and ready for your catalog.

04

Optimize

After launch we test, measure, and refine. We tune Core Web Vitals and run conversion experiments so the storefront keeps earning, not just looking good.

Questions, answered

What merchants ask before they commission a BigCommerce redesign.

The questions we hear most before a redesign starts. If yours isn't here, just ask.

Do you design a custom BigCommerce theme or start from a Stencil base theme?

Both paths are on the table, and we recommend the one that fits your goals and timeline. For brands that need a distinct storefront we design and build a fully custom Stencil theme. When speed matters, we start from a strong Stencil base theme and rework it into something that looks bespoke and converts like it.

Can you redesign our existing BigCommerce store without rebuilding everything?

Yes. We often start with a focused redesign of the templates that move revenue, like the homepage, category, and product pages, then extend from there. We audit the current store first and document what is costing you conversions before touching the design.

How long does a BigCommerce web design project take?

A focused redesign of the key revenue templates lands in three to five weeks. A full custom Stencil theme design and front-end build runs eight to fourteen weeks depending on scope. You get a real timeline in week one, tied to the templates and features your store actually needs.

Can non-technical staff edit pages after the design ships?

Yes. We set up Makeswift, the visual page builder for BigCommerce, so your marketing team can edit content, build landing pages, and update sections with no code. We design reusable blocks so the store stays on-brand long after launch.

Do you handle both the design and the front-end development?

Yes, and that is the point. Design and front-end engineering live with the same senior team, on Stencil or headless with Catalyst, so what gets designed is what gets shipped, accurate and fast, with no handoff gap between the mockup and the live store.

Do you design for headless BigCommerce and B2B?

Yes. We design and engineer Stencil themes, build headless storefronts on Catalyst when the brand needs them, and handle B2B storefront design including company accounts, price lists, and quoting, with the same senior team across all of it.
