BigCommerce Development Services — Custom Stores Built to Convert
LampProgramming is a BigCommerce development agency specialising in custom Stencil theme development, BigCommerce app integrations, headless BigCommerce builds, and platform migrations from WooCommerce, Magento, and Shopify. We build BigCommerce stores for ecommerce businesses that need performance, scalability, and full control over the buying experience — not a template.
We build enterprise-ready BigCommerce stores that scale — from custom Stencil themes and headless Vue.js storefronts to complex ERP integrations and platform migrations. Serving the USA, Canada, and Australia.

Whether you're launching, migrating, or scaling on BigCommerce — we have the expertise to deliver.
Custom Stencil Theme Development
Bespoke BigCommerce themes built with Stencil and Handlebars.js — fast, responsive, and built to match your brand rather than a generic template.
Headless BigCommerce (Vue.js)
Decouple your storefront from the BigCommerce backend using Vue.js and the GraphQL Storefront API for maximum flexibility and performance.
App & Integration Development
Connect BigCommerce to your ERP, CRM, accounting software, fulfilment systems, and custom internal tools via REST and GraphQL APIs.
Platform Migration to BigCommerce
Move from Shopify, Magento, WooCommerce, or any other platform with full data migration, SEO redirect mapping, and zero downtime cutover.
B2B BigCommerce Development
Customer-group pricing, quote workflows, purchase order support, and custom catalogue visibility rules for B2B and wholesale operations.
Maintenance & Retainer Support
Ongoing development support, theme updates, performance monitoring, and new feature delivery under a predictable monthly retainer.
Custom BigCommerce Theme Development (Stencil)
Your storefront's theme is the first thing customers judge — and the first thing that affects conversion rate, load speed, and search rankings. We build custom BigCommerce themes using Stencil, BigCommerce's official theming framework, and Handlebars.js templating. That means no off-the-shelf theme constraints: every product page, category layout, cart, and checkout step is built around how your customers actually shop, not a generic template's assumptions.
A Stencil build from LampProgramming includes responsive design across every breakpoint, Core Web Vitals-optimised markup and asset loading, accessible markup that meets WCAG standards, and a component structure your team can extend without breaking the theme on the next BigCommerce platform update. It's one part of a broader ecommerce development engagement for stores that need more than a new theme skin — if you're outgrowing a purchased Stencil theme's limitations, we can rebuild it as a custom theme without losing your catalogue or SEO equity.
BigCommerce App & API Integrations
BigCommerce's app marketplace covers a lot of ground, but most growing stores eventually need something the marketplace doesn't offer — a specific ERP connection, a custom pricing rule, or a workflow that spans multiple systems. We build custom integrations using BigCommerce's REST and GraphQL APIs to connect your store to the tools that actually run your business.
That includes ERP and inventory systems, accounting platforms like Xero and QuickBooks, shipping and fulfilment tools like ShipStation, email and loyalty platforms like Klaviyo and LoyaltyLion, tax automation through Avalara, and custom internal tools built specifically for your operations. Every integration is built to survive BigCommerce API version updates and documented so your team isn't dependent on us for every future change.
BigCommerce Migration Services
Moving an established store to BigCommerce is a data-integrity problem before it's a design problem. We handle full platform migration projects from Shopify, Magento, WooCommerce, and custom-built platforms — including product catalogues, customer accounts and order history, content and blog data, and every URL that currently ranks in search.
301 redirects are mapped before launch, not after, so a store leaving Shopify development constraints like transaction fees doesn't lose its search rankings in the process. We run the new BigCommerce store in a parallel environment for testing, coordinate the DNS cutover for minimal downtime, and monitor rankings and traffic for 60 days post-migration to catch anything that needs adjustment early.
Headless BigCommerce Development
Headless BigCommerce separates your storefront from BigCommerce's backend commerce engine, letting us build the frontend in React, Vue.js, or Next.js while BigCommerce continues to handle products, inventory, pricing, and checkout through its GraphQL Storefront API. It's the right call when you need frontend performance and design flexibility that a Stencil theme can't deliver, or when your brand needs a storefront experience closer to a custom application than a traditional ecommerce template.
We've built headless BigCommerce storefronts for B2B wholesale platforms handling customer-group pricing and quote workflows, and DTC brands that needed sub-2-second load times across every device. Headless isn't the right fit for every store — we'll tell you honestly during discovery if a Stencil theme will serve you just as well for less investment.
BigCommerce SEO & Performance Optimisation
Ranking on BigCommerce depends on more than good copy. We handle the technical side of BigCommerce SEO — meta title and description templates across product and category pages, structured data (Product, Offer, and Organization schema) so listings are eligible for rich results, clean URL structures that survive migrations and category restructuring, and collection page optimisation so your highest-value pages aren't thin, duplicate, or buried three clicks deep.
On performance, we optimise image delivery, defer non-critical JavaScript, audit third-party app scripts that are often the real cause of a slow storefront, and fix Core Web Vitals issues that affect both rankings and conversion rate. A fast, well-structured BigCommerce store converts better and costs less to acquire customers for — which is usually a bigger lever than another round of ad spend.
Why Choose LampProgramming for BigCommerce Development
There's no shortage of agencies that list BigCommerce as one of six platforms they support. We don't — our developers work in Stencil, the BigCommerce API, and BigCommerce's B2B Edition specifically, which means fewer surprises mid-project and fewer workarounds after launch.
Every engagement starts with a fixed-price quote after a free discovery call, not an open-ended hourly estimate. We document every integration and theme decision so your team isn't locked into us for routine changes, and retainer clients get a dedicated developer who already knows their store rather than whoever's available that week. Whether you're a merchant in BigCommerce Los Angeles or anywhere else in the US, Canada, or Australia, the process is the same: a clear scope, a fixed price, and a store built to actually convert.

Why BigCommerce for Your Ecommerce Business?
BigCommerce is the platform of choice for high-growth B2C and B2B merchants — here's why.
No Transaction Fees
Unlike Shopify, BigCommerce charges zero transaction fees on any payment gateway — a significant saving for high-volume merchants.
Enterprise B2B Features
Native B2B edition with customer group pricing, quote management, purchase orders, and corporate account structures — no expensive apps required.
Open SaaS Architecture
BigCommerce's open APIs and headless capabilities give developers full freedom to build custom storefronts while keeping commerce logic on a stable SaaS platform.
No Platform Lock-in
Because BigCommerce is API-first, your front-end can be rebuilt or migrated independently without touching your catalogue, pricing, or order data.
Strong Multi-Currency & Multi-Storefront
Manage multiple brands or regions from a single BigCommerce backend — with dedicated storefronts, currencies, and pricing per channel.
Robust Native Catalogue Management
Advanced variant rules, product modifiers, complex option sets, and faceted search built in — ideal for merchants with large or complex catalogues.
