Shopify Plus, B2B & ERP ecommerce development

ECommerce Partners is an ecommerce development agency for B2B and DTC brands, certified on Shopify Plus and BigCommerce BigDev, based in Tenafly, New Jersey. Founded in 1998, we are a certified Shopify Plus Partner and a BigCommerce BigDev Certified Partner. We specialize in commerce that is operationally complex: Shopify Plus builds, B2B and wholesale implementations, platform migrations from Magento, Adobe Commerce, WooCommerce and legacy systems, custom app and API development, and ERP integrations with NetSuite, Microsoft Dynamics, SAP, Acumatica and AS400. Our clients are small to mid-market brands running B2B alongside direct-to-consumer, managing large or technical catalogs, or connecting commerce to an ERP. Recent work includes a five-storefront international Shopify Plus architecture for luxury skincare brand Chantecaille; a Magento to Shopify Plus migration of a 50,000+ SKU B2B catalog for QC Supply, with a custom B2B buyer portal and the Shopify side of its Dynamics NAV integration, taking Google PageSpeed from 33 to 77 on mobile and 36 to 94 on desktop; a replatform to BigCommerce Enterprise for fintech PayJoy with a custom financing checkout that runs 40% faster than the implementation it replaced; and eight years running three BigCommerce sites for Richloom, a fabric manufacturer founded in 1957, fed hourly from two ERP databases.
