BigCommerce Partner Agency

The BigCommerce agency that scales you without the overhead.

You chose BigCommerce to grow without enterprise licensing and a permanent IT department, and your agency should work the same way. We are a BigCommerce partner whose senior engineers and strategists do the work directly: builds, migrations, and growth with no junior bench and no layers of process between you and the people shipping it.

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.

BigCommerce B2B Edition

BigCommerce B2B Edition, set up for how your wholesale buyers actually order.

B2B Edition is the native wholesale layer for BigCommerce. It adds company accounts, a buyer portal, quoting, shared shopping lists and an invoice portal to the same store that runs your direct-to-consumer site, so one catalog and one backend can serve both channels. Turning it on is the easy part. The work that decides whether wholesale buyers adopt it is mapping your accounts, prices and payment terms onto it, and connecting it to the ERP that already holds those rules. That is the part a BigCommerce agency should own, and it is where most of our B2B Edition time goes.

What B2B Edition gives you natively

BigCommerce documents these as core B2B Edition features. Together they cover the day-to-day buying experience a distributor or manufacturer needs, without a third-party B2B app stacked on the theme.

  • Company accounts with multi-level hierarchies, buyer users and custom roles and permissions
  • A Buyer Portal where buyers manage orders, quotes, invoices, addresses and saved lists
  • Sales staff quoting with custom products, shipping rates and discounts
  • Shared shopping lists and buy again for repeat orders
  • A Quick Order Pad: add by SKU, from past orders, or by CSV upload
  • An Invoice Portal with company-specific payment terms, plus purchase orders and per-company payment method visibility
  • Masquerade, so your sales reps can place orders on behalf of consenting companies
Where the engineering goes

The native features handle the storefront side. A B2B Edition launch succeeds or stalls on the data and workflows around them, and that is where we spend the build.

  • Mapping ERP customers, contract pricing and terms onto companies, customer groups and price lists without creating an unmanageable number of variants
  • Syncing orders, invoices, credit status and inventory with the ERP, which usually stays the system of record
  • Migrating existing wholesale accounts and users so buyers can sign in and reorder on day one
  • Shaping the Buyer Portal, which BigCommerce publishes as open source, around your brand and buyer workflows
  • Keeping DTC and wholesale experiences distinct on one storefront or across multi-storefront
  • Punchout and EDI connections when your largest accounts order from their own procurement systems

We scope B2B Edition against your real account structure, price rules and ERP before anything is configured. See our BigCommerce B2B services for the wholesale build in detail, or compare platforms in Shopify Plus B2B vs BigCommerce B2B Edition.

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. Many brands start small: they hire BigCommerce developer capacity from our senior team first, then grow into the full engagement.

  • 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.

  • Eighteen 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.

What is BigCommerce B2B Edition?

B2B Edition is the native wholesale feature set for BigCommerce. It adds company accounts with buyer roles and permissions, a Buyer Portal, sales staff quoting, shared shopping lists, a Quick Order Pad with CSV upload, and an Invoice Portal with company-specific payment terms, all on the same backend as your DTC store. Existing BigCommerce merchants request it through their BigCommerce account team.

Do we still need an ERP integration with B2B Edition?

In most wholesale businesses, yes. B2B Edition gives buyers the tools to order, but contract pricing, credit limits, invoices and inventory usually live in the ERP. We connect the two so prices and terms in the Buyer Portal match what the ERP will bill, and orders flow back without rekeying.

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.
