A hosted platform shouldn't mean a templated store. Our BigCommerce development services go past Stencil's default limits with custom theme engineering, headless architecture and deep API integrations, built to convert at enterprise volume.
BigCommerce's closed hosted system limits checkout customization and pushes stores toward unoptimized Stencil widget layers that slow pages.
Marketplace themes pile on heavy scripts. Mobile performance drops fast once a catalog grows past a few thousand SKUs.
Custom product options and enterprise ERP connections can strain standard API calls without expert-level code behind them.
As a BigCommerce development company, we don't build generic stores. We use the open-SaaS framework with optimized Stencil code, headless interfaces and deep API systems to grow conversions and keep stores secure.
From high-converting custom themes to advanced headless setups: secure, fast storefronts built for enterprise volume.
Avoid the risks of general web developers with a team that uses the platform's full infrastructure.
| Developer profile | Platform engineering | Project delivery |
|---|---|---|
| General web developer | Basic dashboard changes, marketplace app installs, surface-level CSS. | High risk of broken scripts, platform limit blocks and slow pages. |
| AdvertX BigCommerce expert | Stencil CLI local engineering, custom widgets, GraphQL APIs, headless architecture. | Scalable code, a fast checkout and clean data sync with your other systems. |
A general web developer can install a marketplace app. Few can work inside BigCommerce's Stencil framework or a headless build without hitting platform limits. That is where our BigCommerce development services start.
When you hire BigCommerce developers from AdvertX, you work with the Stencil CLI, GraphQL Storefront API, widget injection and API resource management, with no learning curve.
A custom Stencil theme, a headless build on React or Next.js, or a custom app linking your store to an ERP or CRM, each built with the right architecture.
Core Web Vitals targets are built into theme work from day one. We also build multi-region storefronts and native B2B company accounts, custom pricing and quote workflows.
Every theme upgrade or custom app goes through Git version control and staging before it touches your live store.
We don't quote a fixed price or timeline upfront; every BigCommerce development services project is scoped on a call. We commit to platform-native engineering, careful testing and storefronts built for real enterprise volume.

A dedicated BigCommerce developer works with the Stencil CLI, GraphQL Storefront API and headless architecture, layers a general web marketer usually can't touch. That prevents broken scripts and slow pages as a store grows.
BigCommerce headless development separates the front end (React, Next.js or Gatsby) from BigCommerce's commerce engine. You get faster pages, more flexible content and easier multi-storefront management than a standard Stencil theme allows.
Custom BigCommerce app development covers private, business-specific apps and public marketplace apps, connected through secure APIs to ERP, CRM and WMS systems, built to sync data cleanly within API limits.
Speed is handled at the Stencil code level: script optimization, Core Web Vitals targets built into the theme from the start, and GraphQL-based headless setups for stores that need very fast pages.
Yes. Big Commerce B2B functionality covers company accounts, custom pricing and quote workflows, which we set up and extend through the platform's native B2B tools and APIs.
Yes. A BigCommerce dropship app usually syncs supplier inventory, routes orders automatically and updates stock in real time. We build it as a custom app that fits your supplier workflow.
It depends on how much API-level customization and native B2B or multi-storefront capability you need. BigCommerce offers deeper backend flexibility; Shopify leans toward simplicity. See the BigCommerce website examples above, and we can walk through more on a call.
