Common questions about BigCommerce development

Short answers to the questions teams ask most often in our scoping calls. If you don't see your question, the contact form routes straight to the lead engineer for this service.

What does BigCommerce development include?
Custom Stencil theme builds, BigCommerce B2B Edition configuration, headless BigCommerce on Next.js or Astro, ERP and PIM integration, custom Page Builder widget development, Multi-Storefront for international, and Channels API integration for multi-channel selling. Built by experienced BC partner developers.
BigCommerce vs Shopify Plus: which should we choose?
BigCommerce gives you full URL control, more flexible API limits, and stronger B2B Edition pricing per tenant. Shopify Plus gives you tighter app ecosystem, Hydrogen for headless, and a unified B2B + DTC tenant model. We're platform-agnostic; the right choice depends on your B2B needs, integration stack, and team headcount.
How long does a BigCommerce build take?
Fresh Stencil builds: 8 to 16 weeks. B2B Edition builds: 10 to 18 weeks. Headless BC builds: 10 to 16 weeks. Replatforms to BigCommerce: 8 to 20 weeks depending on source. Theme refresh: 4 to 8 weeks. Discovery phase produces fixed-scope quotes.
Do you build headless BigCommerce stores?
Yes. Next.js 15 against BigCommerce GraphQL Storefront API, with Sanity or Contentful for CMS and Algolia or Typesense for search. Common pattern: BC as the back-end source of truth, Next.js front-end on Vercel or Netlify with edge caching. Sub-2-second LCP achievable on PDP and PLP.
Can you integrate BigCommerce with NetSuite or SAP?
Yes. Live integrations with NetSuite (via our dedicated NetSuite Connector), SAP B1, Acumatica, and Microsoft Dynamics 365 on production BC stores. Standard sync: customers, customer-group pricing, inventory, orders, fulfillment status. Custom middleware where a native connector doesn't exist.
What support do you offer after a BigCommerce build launches?
Three tiers: Essential (~20 hours per month, 8 business hour SLA), Growth (~40 hours per month, 4 business hour SLA, feature work included), Enterprise (80+ hours, 24/7 critical SLA, BFCM war room). Same team that built the store handles ongoing work for continuity.

BigCommerce development: Stencil, headless, B2B, and the full integration stack

BigCommerce development is a different discipline than Shopify or Magento development. Stencil's Handlebars templates, BC's GraphQL Storefront API, B2B Edition's quote workflows, and the platform's URL-control model each create design space and constraints. Below is the actual scope of work our BC development team ships, what platform each capability fits, and how we stage builds.

What's in a BigCommerce development engagement

Stencil theme work

Handlebars templates, SCSS architecture, lazy-loaded sections, Core Web Vitals optimization, and custom Page Builder widgets for the marketing team. Built from BC's Cornerstone theme or a fresh starter, not by retrofitting another platform's theme.

B2B Edition configuration

Company accounts, buyer hierarchy, price lists per customer group, payment terms, quote workflow, sales rep impersonation, and shopping lists. Out-of-box features configured to match your sales process, not custom-coded.

ERP and integration layer

Direct API integration with NetSuite (via our dedicated Connector), SAP B1, Acumatica, Microsoft Dynamics 365. CPQ tools, marketing tools, OMS. Tested on staging with synthetic orders before production cutover.

Headless front-end (when warranted)

Next.js 15 or Astro against BC GraphQL Storefront API, with Sanity or Contentful for CMS and Algolia or Typesense for search. BC stays the back-end source of truth; front-end ships on Vercel or Netlify with edge caching.
