Why a partner, not a stopgap

A senior team for the whole build, not a patch for one ticket.

The cheapest BigCommerce help is also the most expensive when the store stalls at scale. We are the BigCommerce development agency brands hire when the platform is core to the business and the work has to be right. You get strategy, design, and engineering from one team, plus the BigCommerce development services to back it up, so the build ships and the numbers follow.

When to go headless on BigCommerce

Stencil or Catalyst (headless)? When a brand should make the jump.

BigCommerce open SaaS lets you build the storefront two ways: a hosted Stencil theme, or a Catalyst headless front-end on the same backend. Both are first-class. As a BigCommerce partner we are candid about the line, and we only point a brand at headless when the payoff is real, not because it sounds impressive.

Stencil (built-in)

Stencil is the native theme engine, Handlebars templates rendered by BigCommerce itself. You get a fast storefront, the page-level merchandising the admin exposes, and the Makeswift visual page builder, with no separate front-end to host or maintain. Most mid-market DTC and B2B stores ship here and run for years before headless earns its keep.

Best when
  • You want a fast build on a proven, hosted theme
  • Merchandisers need to edit pages without engineers
  • One storefront, standard catalog and content needs
Catalyst (headless)

Catalyst is the BigCommerce headless stack, a React and Next.js storefront querying the GraphQL Storefront API, with the catalog, cart, and checkout still run by BigCommerce. It buys you full control over the front-end, app-grade interactivity, and a content layer of your choosing, at the cost of a real engineering build and ongoing front-end ownership.

Best when
  • You need a bespoke, app-like storefront experience
  • A custom CMS or content workflow drives the front-end
  • Multiple brands or regions share one BigCommerce backend

We size Stencil against Catalyst on your real requirements as part of BigCommerce development services.

Why brands choose IWD

A BigCommerce partner you can keep for years, not a project.

The best agency relationships compound. The longer a senior team knows your store, your catalog, and your customers, the faster every next build ships and the more it returns.

  • A BigCommerce partner with real depth

    We are a BigCommerce partner agency with engineers who know open SaaS at the source level, from Stencil and the Checkout SDK to Catalyst, the GraphQL Storefront API, B2B Edition, and multi-storefront.

  • One senior team, full stack

    Strategy, design, development, and growth under one roof. No outsourcing, no junior bench, and no finger-pointing between vendors when something needs to move.

  • Sixteen years, 300+ brands

    We have shipped mid-market and enterprise DTC and B2B ecommerce since 2008, across high-volume consumer brands and complex wholesale catalogs that have to scale.

  • We stay for the growth

    About 94% of our clients keep us on after launch. The agency that builds your BigCommerce store is the one that keeps making it perform.

How we work together

A clear path from first call to measurable growth.

01

Discover

Stakeholder workshops, a technical and conversion audit, and competitor benchmarks. We map current-state pain to a clear definition of done.

02

Strategy

A phased roadmap, scope, and timeline. We recommend the path that ships value fastest, whether that is a rebuild, a replatform, or focused fixes.

03

Build

Two-week sprints, weekly demos, and a shared backlog. You meet the same senior engineers, designer, and PM every week of the build.

04

Grow

Post-launch performance, CRO, and roadmap work. We do not walk away once it is live. We stay to move the numbers that matter.

Questions, answered

What brands ask before choosing a BigCommerce agency.

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

Why hire a BigCommerce agency instead of a freelancer or in-house developer?

A single developer can close tickets, but a serious store needs strategy, design, senior engineering, and growth working together. As a full-service BigCommerce agency, you get that whole team without the cost and risk of hiring each role yourself, and without the work stalling when one person is out.

Are you a BigCommerce partner agency?

Yes. We are a BigCommerce partner agency with deep experience on the open SaaS model. We build with Stencil or a Catalyst headless storefront, wire custom checkout through the Checkout SDK, and ship B2B Edition and multi-storefront across mid-market and enterprise DTC and B2B.

What does a full-service BigCommerce agency engagement include?

Ecommerce strategy and roadmap, UX and conversion design, senior BigCommerce development, Catalyst and headless storefronts, B2B Edition, multi-storefront, replatforming, SEO, CRO, and ongoing growth. You can start with one of these or the whole journey.

Can you migrate our store to BigCommerce from another platform?

Yes. Replatforming is one of the most common reasons brands come to us. We carry over catalog, customers, orders, and SEO equity, plan the cutover in stages to de-risk it, and rebuild the storefront and integrations on BigCommerce the right way.

Do you build BigCommerce B2B and wholesale?

Yes. We build B2B on BigCommerce B2B Edition with company accounts, customer-specific price lists, quoting, and a buyer portal, running alongside DTC on the same backend. It is the same senior team across the consumer and wholesale sides of the business.

How do you scope and quote a BigCommerce engagement?

Every engagement is scoped to your business: where you are today, what you want to build, the number of storefronts, B2B requirements, and the work it takes to get there. You get a firm, itemized quote on the first call, with no long sales cycle, so there are no surprises before anything begins.
