BigCommerce Specialists · Stencil, B2B & Headless · 300+ Stores
White Label BigCommerce Development for Digital Agencies
Your agency wins the BigCommerce brief. We build the store – custom Stencil themes, B2B Edition, headless builds, and platform migrations – entirely under your brand. As AI tools help agencies pitch more complex eCommerce work, the challenge is always delivery. That is what we solve. 300+ BigCommerce stores delivered. Your clients never know we exist.
The White Label BigCommerce Agency
for Mid-Market and Enterprise Work
BigCommerce is the platform that enterprise and mid-market brands choose when they need more than Shopify's transaction-fee model allows, deeper native B2B features, true multi-storefront capability from a single backend, or the open API access that headless commerce requires. It is also the platform where agencies need genuine technical depth – Stencil theming is not Shopify Liquid, BigCommerce B2B Edition is a serious enterprise product, and the GraphQL Storefront API demands real implementation expertise. We have been building on BigCommerce since 2014. When your agency brings us in, you access that depth under your own brand without adding specialist headcount.
What We Deliver
White Label BigCommerce Services
From Stencil Theme to Live Store
Every BigCommerce engagement follows the same process: your brief, our build, your brand on every deliverable. Whether it is a custom Stencil theme, a B2B Edition setup, or a complex migration, your client never knows we were involved.
Custom BigCommerce Stencil Theme Development
We build fully custom BigCommerce themes using the Stencil framework – Handlebars.js templating, SCSS, and the Stencil CLI. Every theme is built from scratch to match your agency's Figma specification precisely, with BigCommerce Page Builder editability built in so your client can manage content, swap sections, and update the store without touching code. We do not use pre-built Stencil themes or marketplace themes as a starting point unless you specifically ask. Our developers use AI-assisted layout analysis during the Figma-to-Stencil handoff to identify conversion friction and accessibility issues before a line of Handlebars is written. The result is a theme that is fast, accessible, and genuinely maintainable by your client's team after handoff.
BigCommerce B2B Edition & Enterprise Commerce
BigCommerce B2B Edition is one of the most capable native B2B commerce products on the market, and it is where the platform genuinely separates itself from Shopify for enterprise work. We implement and customise B2B Edition for agency clients covering company account hierarchies with multi-buyer roles and permission levels, purchase order workflows and net payment terms for procurement teams, shared shopping lists and requisition management, quote management and negotiated contract pricing, tiered pricing by company, buyer group, or custom segment, and custom B2B portal interfaces that match your client's brand. B2B Edition projects require thorough scoping because the business logic varies considerably between clients – we scope in detail before any code is written, and we will flag complexity honestly rather than treating every enquiry as a standard project.
Headless BigCommerce with Next.js or Gatsby
BigCommerce's open architecture makes it a strong headless commerce backend. We build headless BigCommerce storefronts using Next.js or Gatsby on the frontend and the BigCommerce GraphQL Storefront API on the backend. Headless builds give your client full control over the frontend experience while BigCommerce handles the commerce layer – products, pricing, cart, checkout, and order management. Common use cases include high-traffic DTC brands needing sub-second page loads, multi-brand or multi-region storefronts with a shared backend, and content-rich experiences managed through a headless CMS like Contentful or Sanity alongside the BigCommerce commerce layer. We scope each headless BigCommerce project with care and will advise when a well-built Stencil theme would meet your client's actual requirements at lower cost and complexity.
BigCommerce Multi-Storefront Configuration
BigCommerce Multi-Storefront lets a single BigCommerce account power multiple distinct storefronts from one backend – an advantage for brands operating across regions, agencies managing several client brands on shared infrastructure, and businesses running separate B2B and B2C channels side by side. We configure multi-storefront setups covering independent Stencil themes per channel, separate URL structures and domain mapping, per-channel catalogue and pricing visibility with customer group assignments, per-storefront payment and shipping rules, and independent SEO and metadata configurations so each channel performs in organic search independently. We also advise on when multi-storefront is the right architecture versus separate BigCommerce accounts, because the answer is not always obvious and the wrong decision creates long-term maintenance complexity.
BigCommerce Platform Migrations
Moving to BigCommerce from another platform is a significant technical undertaking, and the common failure modes – data loss, broken redirect chains, post-migration performance issues, and SEO damage – are entirely avoidable with proper process. We handle BigCommerce migrations from Magento, Shopify, WooCommerce, Salesforce Commerce Cloud, Volusion, 3dcart, and custom-built eCommerce platforms. A migration covers product data with full option set, variant, and custom field mapping; customer records and order history; URL structure preservation with a complete 301 redirect map to protect organic rankings; product imagery and media migration; and a pre-launch technical and SEO audit before any live domain is touched. We run every migration on a staging store first and perform a full data integrity check before sign-off. If a migration has complexity that will affect timelines or cost, we tell you before the contract is signed.
BigCommerce API Integrations & Custom Scripts
BigCommerce's open API architecture is one of its genuine strengths over more closed SaaS platforms. We use the BigCommerce REST Management API, Storefront API, GraphQL API, and Webhooks to build integrations between BigCommerce and the external systems your clients' businesses depend on. Common integration work includes ERP and inventory management system sync, CRM connections for customer data and order history, PIM integrations for product data and media management, custom shipping rate calculators using the BigCommerce Shipping API, payment gateway integrations beyond the defaults, loyalty and rewards programme connectors, and real-time pricing engines that pull from external databases. Our AI-supported code review runs on every integration before deployment to catch security issues, API rate-limit risks, and data handling errors before they reach your client's live store.
BigCommerce Speed Optimisation & Core Web Vitals
A slow BigCommerce store loses conversions and search rankings. Stencil themes can be fast, but third-party scripts, unoptimised images, poor CDN configuration, and heavy widget stacks accumulate performance debt quickly. We run full Core Web Vitals audits covering Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint, then address the root causes: render-blocking scripts, unoptimised image delivery across product and category pages, Stencil template rendering inefficiencies, script injection from third-party apps, and CDN and caching configuration gaps. After optimisation, AI-powered performance monitoring tracks the live store automatically so regressions are identified before they affect your client's traffic and revenue.
BigCommerce Maintenance, Support & Retainer Services
A live BigCommerce store needs consistent technical attention after launch. Platform updates, Stencil compatibility patches, app conflicts, new product launches, seasonal promotional work, conversion rate optimisation, and A/B testing of product pages and checkout flows all require a team with knowledge of the original build. You sell the ongoing support contract to your client. We run it entirely under your brand. Retainer clients benefit from AI-powered performance monitoring that flags Core Web Vitals regressions, checkout funnel drop-offs, and crawl anomalies automatically so your account managers can deliver proactive updates rather than waiting for your client to report a problem. Our eCommerce SEO and GEO optimisation team covers BigCommerce-specific structured data, product schema, and AI search visibility alongside traditional organic performance.
Why Axis Web Art for BigCommerce
What Separates a Great
BigCommerce White Label Partner?
Real BigCommerce Depth. Not Just Platform Familiarity.
There is a meaningful gap between an agency that has built a few BigCommerce Stencil themes and one that has delivered 300+ stores across the platform's full feature range – custom Stencil theming, B2B Edition configuration, Multi-Storefront setup, headless GraphQL builds, and complex Magento-to-BigCommerce migrations. Our BigCommerce developers have been working on the platform since 2014. They understand the Stencil rendering pipeline, the BigCommerce API rate-limit model, the B2B Edition data architecture, and the practical implications of headless versus traditional Stencil for different client profiles. When your agency uses us, that depth goes out under your brand.
300+ stores · Stencil · B2B Edition · Headless · 2014AI Is Built into Our BigCommerce Delivery Process.
Our BigCommerce team integrates AI tools at every stage that matters for quality. AI-assisted layout analysis during the design-to-Stencil handoff surfaces UX friction, accessibility gaps, and mobile performance issues before templating begins. AI-supported code review runs on every Stencil theme, API integration, and custom script before deployment – catching security issues, performance problems, and API misuse that only surface in production when they cause damage. Live retainer stores benefit from AI-powered performance monitoring that flags Core Web Vitals regressions and checkout funnel drops automatically. And our GEO optimisation work structures BigCommerce product and category content so your clients appear in AI-generated search responses alongside traditional rankings. These are active tools in our workflow, not positioning claims.
AI in design · code review · performance · GEO SEOPure White Label. We Do Not Take Direct Clients. Period.
We work exclusively for agency partners. There is no direct client division, no parallel business, and no interest in building our own client list. Every developer, designer, and project manager on our team exists to deliver work under your agency brand. We sign an NDA before any project begins, operate using your email domain if required, use your project management tools, and have maintained that boundary without exception across 40+ agency partnerships since 2011. Your BigCommerce clients stay yours. No Axis Web Art branding ever appears in the work, and we have never made a pitch to an agency partner's client in 15 years of operation.
No direct clients · NDA from day one · Est. 2011Honest BigCommerce Scoping. We Tell You What Is Complex Before You Commit.
BigCommerce projects that go wrong almost always fail for the same reasons: migrations scoped without understanding the source platform's data complexity, B2B Edition implementations that did not account for the client's actual business logic, and headless builds started before the architecture was validated against the client's performance and content requirements. We scope every BigCommerce project in detail before development begins. If a Magento migration has product data complexity that will affect the timeline, we say so in the scoping phase. If a headless build is technically impressive but commercially unnecessary for your client, we tell you. That honest scoping is what makes your agency look reliable to your clients, and it is what keeps our agency partners returning.

Three Areas Where Our
BigCommerce Depth Shows
BigCommerce covers a broader feature surface than most agencies realise. Here are the three areas where our team's depth consistently makes the difference on complex projects.
Stencil Theme Development & Page Builder
We build Stencil themes from scratch using Handlebars.js, SCSS, and the Stencil CLI. Every theme is structured for BigCommerce Page Builder editability – sections and widgets are set up so your client can manage content, update layouts, and run promotional campaigns without developer involvement for routine changes.
For agencies with clients on older Blueprint themes, we also run theme modernisation projects – migrating from BigCommerce's legacy Blueprint framework to current Stencil architecture while preserving brand identity and any existing customisations. Stencil brings mobile performance, Page Builder support, and access to current BigCommerce features that Blueprint cannot support.
BigCommerce B2B Edition & Multi-Storefront
The two features that separate BigCommerce from Shopify at the mid-market and enterprise level are B2B Edition and Multi-Storefront. B2B Edition turns BigCommerce into a genuine wholesale and procurement platform – company hierarchies, purchase orders, negotiated pricing, and shared requisition lists. We configure and customise B2B Edition setups with the business logic that each agency client's specific use case requires rather than defaulting to the out-of-box configuration.
Multi-Storefront allows a single backend to power multiple branded channels. We configure per-channel Stencil themes, catalogue visibility, pricing, and domain mapping so each storefront behaves independently from the customer's perspective while remaining manageable from one BigCommerce admin.
Headless BigCommerce & API-First Commerce
BigCommerce's open API architecture is purpose-built for headless commerce. We build headless storefronts using Next.js or Gatsby connected to the BigCommerce GraphQL Storefront API for product data, cart, and checkout. Headless BigCommerce is the right choice when a client needs a React-powered frontend with full creative control, a content-first experience where a headless CMS like Contentful manages editorial content alongside the commerce layer, or a shared backend powering multiple branded storefronts.
We also build complex API integrations between BigCommerce and external business systems – ERPs, PIMs, CRMs, fulfilment platforms, and custom databases – using the REST Management API, Webhooks, and custom event-driven architectures. AI-supported code review covers all API work before deployment.
Who We Work With
The BigCommerce Partner Built for
Agency Capacity, Not Competition
eCommerce Agencies Pitching BigCommerce
You have landed a BigCommerce opportunity – or want to start winning them – but your team's primary experience is on Shopify or WooCommerce. We are your BigCommerce development arm. You quote, manage the client, and present the work under your brand. Your agency has always done BigCommerce. No one needs to know the build team was external.
Digital Agencies with Enterprise eCommerce Clients
Your agency manages marketing, strategy, or design for enterprise clients who operate on BigCommerce. Every time there is a technical requirement – Stencil customisation, B2B Edition configuration, a new API integration, or a Multi-Storefront setup – you either turn it down or send it to a team you are not fully confident in. We handle the BigCommerce technical work so you retain the full client relationship and the complete scope.
Agencies with BigCommerce Migration Projects
You have a client moving from Magento, Shopify, WooCommerce, or Salesforce Commerce Cloud to BigCommerce. Migrations of this scale involve real data complexity – product variants, customer history, order records, URL structures, and SEO continuity. You need a team that has handled this before, not one learning on your client's project. We have migrated dozens of stores to BigCommerce and will scope the data work honestly before any contract is signed.
Agencies Winning BigCommerce B2B Contracts
You have a B2B or wholesale client who has chosen BigCommerce because of B2B Edition, or you are pitching one and need confidence that the technical delivery is solid. B2B Edition is a genuine enterprise product and its configuration requires understanding the client's business logic before a single setting is touched. We have built 30+ B2B and enterprise BigCommerce projects. We scope B2B Edition work in detail and deliver it to a standard that makes your agency look exceptional to the client.
Agencies Scaling BigCommerce Work in the AI Era
AI tools help you scope BigCommerce projects faster and pitch with more confidence than your team size has historically allowed. The pipeline grows faster than your BigCommerce development capacity. You are winning work you need external help to deliver. That is exactly what we are built for. You keep using AI to win more BigCommerce work. We build every project, on time, under your brand, with the technical depth the platform requires.

How It Works
From Brief to Live BigCommerce Store.
Five Steps. Zero Friction.
Share your BigCommerce project brief – Figma files, spec document, or a plain-English overview. We ask the right scoping questions and return a clear proposal within 24 hours. Complex B2B Edition or migration scopes get a detailed breakdown before any commitment.
We sign a mutual NDA before any project files or client information are shared. Confidentiality is not negotiable or an optional add-on. It is the first step of every engagement we have run since 2011.
We assign a dedicated BigCommerce developer, designer, and project manager within 48 hours. For B2B Edition or headless builds, the assigned developer has specific experience on those project types from day one.
We build to your spec using your preferred tools. AI-supported code review runs on every Stencil theme, API integration, and custom script before you see it. Staged milestones, clear progress, and fast turnaround on feedback.
Every deliverable goes out under your agency name. No Axis Web Art branding, no direct client contact, no footprint in the work. Your client receives a polished BigCommerce store. Your agency takes the credit.
What Agency Partners Say
Heard from the Agencies
We Work Behind
"Axis Web Art has been an exceptional white label agency partner for us. They delivered a complex Shopify Plus build exactly on spec and on time. Our client had no idea we had a partner team involved – which is exactly what we needed. We will be working with them on every future project."
"We have used several white label development partners over the years. Axis Web Art stands apart – the communication is proactive, the code quality is consistently high, and they understand what it means to work under our brand. They feel like an extension of our own team, not a vendor."
"Reliable, skilled, and completely invisible to our clients – that is everything we ask for in a white label agency. The Axis Web Art team handled a full WooCommerce migration for one of our most demanding clients. Delivered clean, on time, and without a single revision request."
"The level of professionalism and technical depth at Axis Web Art is impressive. We brought them in on a WordPress build with tight timelines and multiple stakeholders. They navigated the complexity with ease, communicated clearly at every stage, and delivered work that genuinely impressed our client."
