Diff Agency

What Diff Agency does

Diff Agency is a Montreal-headquartered digital commerce agency founded in 2011, operating as Shopify's longest-standing partner agency and holding Shopify Platinum Partner status. The firm delivers a five-pillar professional services portfolio: Tailored Commerce Builds (Shopify Plus builds, headless Hydrogen implementations, modular theme architecture, and migrations from Salesforce, Adobe Commerce, BigCommerce, WooCommerce, and Magento), Integration Solutions (ERP, OMS, PIM, CRM, 3PL, POS, subscription, and payment/tax integrations), UX/UI Design (research, mobile-first and accessibility-first interfaces, design systems), Growth & Analytics (CRO, A/B testing, analytics setup, full-funnel optimization), and Bespoke Application Development (custom OMS, customer portals, dashboards, fraud monitoring, loyalty platforms, B2B portals).

The technology stack is anchored in Shopify Plus, with deep capability across Shopify Hydrogen for headless commerce, Shopify Subscriptions API, Shopify B2B, and Shopify POS. Differentiation comes from 200+ custom Shopify apps built, 60+ ERP integrations (SAP, Microsoft Dynamics AX, NetSuite and others), and reusable architectural patterns such as multi-region Shopify deployments and modular component libraries. Technology partners include Algolia, Bloomreach, Yotpo, Recharge, Contentful, Nosto, Loop, Gorgias, Acquia, Adobe Experience Manager, Webflow, and Ordergroove, providing an integrated commerce stack rather than proprietary AI.

Commercially, Diff operates as a bespoke professional services firm with project-based and likely retainer pricing; no public pricing is disclosed. Go-to-market is direct enterprise field sales supplemented by Shopify partner referrals. The customer base spans 150+ enterprise brands across fashion and apparel (Kith, Tommy John, Gorjana, Fashion Nova, Gymshark, Rocky Brands), home and furnishing (Boll & Branch, Tonies), food and beverage (Sakara Life, DAVIDsTEA, Wild Fork), retail (Giant Tiger), professional services (BDO), and entertainment (Lionsgate). In 2025, the agency was acquired by VML, part of WPP, integrating Diff into a global commerce and marketing network while preserving its Shopify specialization.
