BigCommerce is a cloud-based e-commerce SaaS company that provides an enterprise-grade platform for building and operating online stores across B2C and B2B channels. Its architecture supports API-first and headless builds, while offering hosted storefront and checkout capabilities.

Platform modules

Core features include storefront themes, catalog and inventory tools, promotions, cart and checkout, SEO, and analytics. BigCommerce supports multi-brand and international expansion through Multi-Storefront (multiple storefronts managed from one control panel) and robust developer APIs for custom experiences.

B2B and ecosystem

B2B Edition adds company accounts and a Buyer Portal, quoting workflows, and controlled payment options (e.g., purchase orders).

An app marketplace and integrations connect to ERP, accounting, marketing, and fulfillment tools.
