BigCommerce Development for Growing and B2B Stores

BigCommerce development is a good match for merchants who have outgrown a simple storefront but do not want to run their own servers. BigCommerce is a hosted platform with a strong API, native multi-storefront support and a dedicated B2B Edition, which makes it popular with wholesale brands, manufacturers and retailers running several catalogs.

As a BigCommerce development company and agency, we build and extend stores for those merchants. That covers custom themes, headless front ends, integrations with ERP and inventory systems, and migrations onto the platform. We start every project by understanding how you sell, because catalog structure, pricing rules and checkout requirements decide most of the technical choices.

Our BigCommerce Development Services

• Stencil theme development: custom themes or heavy customization of BigCommerce's default Stencil theme, using Handlebars templates, SCSS and the Stencil CLI, with Page Builder regions so your team can edit layouts.
• Headless storefronts with Catalyst: Next.js storefronts built on Catalyst, BigCommerce's open-source headless framework, for brands that need full front-end control and content from a separate CMS.
• B2B Edition setup: company accounts, buyer roles and permissions, shared price lists, quote requests and purchase order payments for wholesale customers.
• Multi-storefront: several storefronts, brands or regions run from one BigCommerce back end, each with its own theme, catalog visibility and settings.
• Integrations: ERP, PIM, inventory, shipping and marketing tools connected through the REST Management API, GraphQL Storefront API and webhooks.
• Checkout customization: changes to the checkout through BigCommerce's Checkout SDK and open-source checkout, kept within what the platform supports.
• Custom apps: private and public apps that extend the control panel or connect systems, covered on our BigCommerce app development page.
• Ongoing care: theme updates, script reviews, app checks and fixes after launch through our BigCommerce maintenance plans.
• Migrations to BigCommerce: moves from Magento, WooCommerce and other platforms, with products, customers and orders transferred and every old URL redirected.

How We Deliver BigCommerce Development

1. Discovery (1 to 2 weeks). We review your catalog, pricing rules, customer groups, integrations and current platform. We map which requirements BigCommerce handles natively, which need an app, and which need custom work, so there are no surprises mid-build.
2. Catalog and URL plan (about 1 week). We decide how variant options, modifier options, categories and brands should be set up, and define the URL structure. BigCommerce lets you customize product and category URL patterns, so we plan them to match your existing site where it helps preserve search traffic.
3. Design and build (4 to 8 weeks). Templates are designed in Figma, then our BigCommerce web developers build them as a Stencil theme or a Catalyst storefront in Git, with preview stores for review. We use your real product data from the start.
4. Integration and data (2 to 4 weeks, alongside the build). We connect your ERP, inventory and marketing tools, migrate data, and test order flow end to end, including tax, shipping, payment capture and refunds.
5. Launch and handover (launch week, then 2 weeks of monitoring). We launch with 301 redirects, GA4 ecommerce tracking and a Merchant Center feed checked, then monitor orders and Search Console. Your team gets training on the control panel and any B2B tools.

Steps overlap, so a typical Stencil build runs 8 to 12 weeks end to end. B2B Edition, multi-storefront and Catalyst projects take longer, and discovery sets a firm schedule.

BigCommerce Development Deliverables and Launch Checks

• Requirements map. Every requirement marked as native, app or custom, with the reason, so nothing is built that the platform already does.
• Catalog and URL specification. Option and modifier setup, category tree, brand pages and URL patterns, plus a redirect map from your old platform.
• The theme or storefront in your repository. A Stencil theme or Catalyst app in Git, with build and deploy steps documented.
• Working integrations. ERP, inventory, shipping and marketing connections tested with real orders, plus notes on which system owns each field.
• Tracking and feeds. GA4 ecommerce events, Script Manager entries with consent categories, and a Merchant Center feed checked for errors.
• Training and guides. Page Builder, B2B Edition and order handling guides for your team.

At launch we check that test orders flow through payment, tax, shipping and the ERP, that old URLs redirect to the right new pages, that GA4 purchase counts match BigCommerce orders, and that the Merchant Center feed is approved. In the weeks after, we watch Search Console coverage, Core Web Vitals and order sync errors. Those are the measures we hold ourselves to; sales results depend on more than the build, so we do not promise them.

Stencil or Catalyst: Which Storefront Fits?

For most merchants, a well-built Stencil theme is the right answer. We only recommend headless when the benefits clearly justify the extra cost and maintenance.

Is BigCommerce Better Than Shopify?

Neither is better across the board. BigCommerce is often the stronger choice for B2B selling, multi-storefront setups and catalogs with many product options, while Shopify usually suits direct-to-consumer brands that want the largest theme and app ecosystem and the least technical upkeep.

Payment costs are one concrete difference: BigCommerce does not add its own transaction fee when you use a third-party payment gateway, while Shopify charges one unless you use Shopify Payments. BigCommerce also lets you change product and category URL patterns, which helps when migrating a store with established rankings. If your store is simple and consumer-focused, our Shopify development team is usually the faster route.

BigCommerce Details We Plan Around

• Plan limits tied to sales. BigCommerce plans are linked to your trailing twelve-month online sales, so a growing store can be moved to a higher plan. We factor this into platform cost comparisons.
• Options versus variants. Variant options create SKUs with their own stock and price, while modifier options do not. Getting this wrong makes inventory and feeds unreliable.
• Third-party scripts. Tracking and app scripts should go through Script Manager with the right placement and consent category, not pasted into templates.
• App overlap. Many features are already native. We check before adding an app, since each one adds cost and often front-end weight.

BigCommerce Build Mistakes We Correct

• Theme edits made in the control panel's file editor. Changes with no Git history are overwritten or lost when the theme is updated.
• Using modifiers for real variants. Sizes or colors set up as modifier options cannot hold stock or appear correctly in Google Shopping feeds.
• Tracking pasted into templates. Pixels hardcoded in theme files fire twice once an app adds the same tag, and ignore consent settings.
• Migrations without a redirect map. Old product and category URLs return errors, and the store loses search traffic it already earned.
• Customer groups doing B2B work. Wholesale pricing stretched across customer groups and discount rules when B2B Edition would handle companies, buyers and price lists properly.

BigCommerce Development Services by Business Type

• Manufacturers and wholesalers. B2B Edition with company accounts, price lists, quote requests and purchase orders, connected to the ERP for stock and invoices.
• Retailers with large or configurable catalogs. Variant and modifier planning, product filtering, and bulk data imports that keep thousands of SKUs accurate.
• Multi-brand groups. Several storefronts from one back end, each with its own theme and catalog visibility, so one team manages stock and orders.
• Brands moving off Magento. A hosted platform with fewer servers and patches to manage, while keeping strong APIs for integrations.
• Content-led brands. Catalyst storefronts paired with a headless CMS when editorial content carries the brand.

How to Choose a BigCommerce Development Company

Before comparing BigCommerce development companies, list the parts of your store that are hard: B2B pricing, integrations, migration or headless. Ask each BigCommerce development company how they would handle those specifically, whether they build Stencil themes, Catalyst storefronts or both, and how they test integrations with real order data. Check that the store, repositories and any hosting will be in your name, and that they will tell you when a native feature makes an app or custom build unnecessary.

A short checklist to use in those conversations, whichever agencies are on your list:

1. Ask to see how they plan variant and modifier options before importing products.
2. Ask how theme code is managed. Stencil CLI and Git should be standard, not the control panel editor.
3. Ask how B2B Edition will be configured for your companies, buyer roles and price lists, if you sell wholesale.
4. Ask for their redirect and URL plan if you are migrating, and how they will check it after launch.
5. Ask how tracking will be added through Script Manager and how consent categories will be set.
6. Ask what support looks like in the first weeks after launch and who handles it.

Merchants Our BigCommerce Development Services Suit

A good fit if you:

• Sell to both wholesale and retail customers and need B2B features without running your own servers.
• Run several brands or regions and want one back end for all of them.
• Are moving off Magento and want a hosted platform with strong APIs.
• Already use BigCommerce and need custom theme work or integrations.

Probably not a fit if you:

• Run a small direct-to-consumer store with a simple catalog, where Shopify development is often quicker and has a larger app ecosystem.
• Need deep custom logic across the whole stack, where Magento development or WooCommerce gives more code-level control.

BigCommerce Development Pricing

BigCommerce projects start with a paid discovery sprint that maps requirements, integrations and data migration, and its fee is credited to the build. The build is then quoted at a fixed price, and ongoing work can continue on a monthly retainer. BigCommerce plan fees and apps are billed to you directly.

The main cost drivers are Stencil versus Catalyst, the number of unique templates, B2B Edition setup, how many storefronts are involved, the integrations to build or test, and the volume and condition of data to migrate from your current platform.
