BigCommerce Development: Stencil Themes, Headless & Custom Apps
From custom Stencil themes to fully headless storefronts and BigCommerce app development, we help merchants get the most out of BigCommerce's open, API-first platform.
Everything You Need on BigCommerce, In-House
Custom Stencil Themes
Bespoke storefronts built on BigCommerce's Stencil framework (Handlebars, Stencil CLI, Stencil CSS) tailored to your brand and catalog.
Headless BigCommerce
Fully headless storefronts on React/Next.js consuming BigCommerce's GraphQL Storefront API for total front-end flexibility.
BigCommerce App Development
Custom apps for the BigCommerce App Marketplace or private use, integrating deeply via the BigCommerce APIs.
B2B Edition & Wholesale
Custom pricing tiers, quote workflows, and B2B Edition configuration for wholesale and multi-buyer-group catalogs.
Multi-Storefront & Channels
Multi-storefront setups and channel management for merchants selling across brands, regions or marketplaces.
Migration to BigCommerce
Move from Magento, Shopify, WooCommerce or a legacy platform with full data migration and SEO preservation.
Custom Stencil Theme Development
We build custom BigCommerce themes on the Stencil framework — using the Stencil CLI, Handlebars templating and Stencil CSS/Sass — so your storefront reflects your brand exactly, not a modified default theme.
- Custom Handlebars templates & components
- Stencil CLI-based local development workflow
- Responsive, accessible, performance-tuned front end
- Theme editor-friendly configuration for your team
Headless BigCommerce on React / Next.js
BigCommerce's API-first architecture makes it a strong fit for headless builds. We build custom storefronts on React and Next.js, powered by BigCommerce's GraphQL Storefront API, when you need full control of the front end or a shared backend across multiple brands or regions.
- React / Next.js storefront architecture
- GraphQL Storefront API integration
- Composable commerce & multi-brand support
- Performance-first, SEO-friendly rendering
Custom BigCommerce Apps
From internal operational tools to apps listed on the BigCommerce App Marketplace, we build using BigCommerce's REST/GraphQL APIs, OAuth scopes and webhook system to integrate deeply and reliably with the platform.
- REST & GraphQL API integration
- OAuth, webhooks & single sign-on
- App Marketplace submission support
- Custom internal tools & automation apps
