BigCommerce is one of the few eCommerce platforms built natively for both B2B and DTC sales. Brands that have chosen BigCommerce are often more operationally complex than typical Shopify stores — selling wholesale and direct-to-consumer simultaneously, managing multiple storefronts, or running headless commerce setups.This complexity demands a 3PL that can match it.**B2B + DTC From One Inventory**The core BigCommerce fulfillment challenge is running two fundamentally different order types from the same inventory. A B2B purchase order from a retail account needs routing guide compliance, EDI documentation, and freight delivery. A DTC order needs same-day shipping in branded packaging.3PLCity supports both from one inventory pool. B2B orders route to our wholesale team with appropriate carrier selection, documentation, and retail compliance. DTC orders route to our standard pick-and-pack line with your brand spec. Real-time inventory allocation prevents overselling into wholesale commitments.**Multi-Storefront Support**BigCommerce's multi-storefront feature lets brands run multiple websites from one backend — different brands, different regions, different customer segments. We connect all storefronts to one inventory with separate packing specs and reporting per storefront.**EDI for Wholesale Customers**BigCommerce B2B brands often have retail accounts that require EDI — electronic data interchange for purchase orders (850), advance ship notices (856), and invoices (810). We process EDI transactions for major retail partners through our EDI connections.**Headless BigCommerce**Running BigCommerce headless with a custom frontend? Our integration operates at the API level, not the storefront level — compatible with any frontend framework or custom build.
