ECommerce Partners

About

ECommerce Partners is an ecommerce development agency for B2B and DTC brands, certified on Shopify Plus and as a BigCommerce BigDev partner. Founded in 1998 in a downtown Manhattan office, the agency ran out of New York's tech corridor for nearly two decades before going fully remote, with headquarters now in Tenafly, New Jersey and developers, project managers and designers across the U.S. and Europe. Over 25+ years the team has launched 100+ stores, completed 50+ platform migrations and powered more than $2B in GMV for clients including Chantecaille, QC Supply, C.O. Bigelow, Sabon, PayJoy, KOL Foods and Eberjey.

The work centers on complex commerce. Shopify Plus builds use Shopify Functions, checkout UI extensions, Shopify Flow automation and multi-store setups, while Shopify B2B projects add company accounts, customer-specific pricing and catalogs, payment terms and quick-order forms. The agency also publishes its own B2B Pro Portal app on the Shopify App Store so wholesale customers can manage their own users and locations. Migrations from Magento, BigCommerce and WooCommerce are delivered with zero data loss and SEO preserved, including catalogs of 50,000+ SKUs, and ERP integrations connect stores to NetSuite, SAP, Microsoft Business Central and AS400 systems with real-time sync.

BigCommerce is a genuine practice rather than a footnote, with custom Stencil themes, API and ERP integrations and Open Checkout work for brands that need full control of their checkout and payments. Four principles shape every engagement: the team both builds and consults, senior people lead every project with no bait-and-switch, relationships are long term with most enterprise clients staying 5+ years, and the focus is on mid-market and enterprise brands doing $3M+ online where ecommerce is the operation, not a side channel. New projects can start with a free concept design.

For brands using Zigpoll, ECommerce Partners can build post-purchase, on-site and B2B account surveys into a Shopify Plus or BigCommerce storefront as part of a build or migration, so wholesale buyers and retail customers alike have a direct channel for feedback once the new store is live.
