About This Service

BigCommerce for Mid-Market and Enterprise Commerce at Scale

BigCommerce offers the flexibility of open-source commerce with the operational reliability of a managed SaaS platform — making it the right choice for merchants who need more than Shopify's constraints but do not want the infrastructure overhead of Adobe Commerce.

We build on BigCommerce's Stencil framework and headless capabilities to deliver storefronts that are fast, conversion-optimised, and deeply integrated with your commerce stack. BigCommerce's native B2B features, multi-storefront capabilities, and open API architecture make it particularly strong for complex multi-brand and B2B scenarios.

Our BigCommerce builds are engineered with the same discipline as our other enterprise commerce projects — custom Stencil themes, purpose-built integrations, performance-first configuration, and a documented deployment and testing process that gives you confidence in every release.

  • Custom Stencil themes and headless Next.js storefronts on BigCommerce backend
  • BigCommerce B2B Edition — buyer portals, shared wishlists, payment terms
  • Multi-storefront from a single BigCommerce admin — brands, regions, channels
  • Open API integrations — ERP, PIM, WMS, marketing automation, CRM

Real-World Impact

Use Cases in Production

Real deployment patterns — the specifics vary per client, but the structure stays the same.

B2B Wholesale Portal for a Consumer Goods BrandB2B Wholesale

B2B Wholesale Portal for a Consumer Goods Brand

The Challenge

A consumer goods brand selling through 1,400 retail stockists was managing B2B orders through a separate legacy system that required a dedicated account manager to process every order. Stockists had no self-service and no visibility of their account.

The Solution

BigCommerce B2B Edition implementation with a custom buyer portal. Account-specific pricing, net payment terms, order history, real-time stock visibility, and a re-order feature for repeat purchases. Integrated with the ERP for automatic order import and the WMS for live stock levels.

Outcomes
  • 82% of B2B orders shifted to self-service within 4 months
  • Account manager capacity freed — redirected to 200 new account acquisitions
  • Average order frequency increased from monthly to 2.3× per month
Multi-Storefront Architecture for a Retail GroupMulti-Brand Retail

Multi-Storefront Architecture for a Retail Group

The Challenge

A retail group with 5 distinct brands was running separate BigCommerce stores — each with separate themes, separate integrations, and separate maintenance overhead. The technology team was maintaining 5 essentially identical setups at 5× the cost.

The Solution

BigCommerce multi-storefront implementation with a shared integration layer and brand-specific Stencil themes. One ERP integration, one WMS integration, one Klaviyo integration — all shared across all 5 storefronts. Brand teams control content; engineering maintains one shared infrastructure.

Outcomes
  • Technology overhead reduced by 58% vs. running 5 separate stores
  • New brand storefront deployment time from 8 weeks to under 2 weeks
  • Unified customer data enables cross-brand loyalty and retention campaigns for the first time
Headless BigCommerce with Next.js StorefrontHeadless Commerce

Headless BigCommerce with Next.js Storefront

The Challenge

A fast-growth DTC brand needed a storefront that was faster than any SaaS-hosted frontend could deliver, with full control over the UI and content experience — but without wanting to manage a self-hosted e-commerce backend.

The Solution

Headless BigCommerce with a custom Next.js storefront hosted on Vercel. BigCommerce handles cart, checkout, product data, and order management via API. The frontend delivers edge-rendered pages with sub-second LCP, full CMS editorial control, and complete design freedom.

Outcomes
  • LCP of 0.9s on mobile — top 1% of e-commerce performance globally
  • Conversion rate improved 31% vs. the previous Stencil theme
  • Content team fully self-sufficient — product launches without engineering involvement
