Shopify + Manhattan Active Omni (MAO) Integration
Manhattan Active Omni (MAO) is the enterprise OMS Shopify partnered with most deeply, and SDG implements it the way it was meant to be: MAO as the inventory and fulfillment source of truth, Shopify as the experience.
Manhattan Active Omni integrations in production
Robust Manhattan Active Omni integrations on Shopify, delivered for Barnes & Noble, Indigo Books & Music, Everlane, GAP, and Mattel.
The OMS Shopify built a native app with
Manhattan was the first enterprise OMS to build a native, co-developed Shopify app, with prebuilt flows for orders, inventory, payments, and fulfillment. Manhattan Active Omni (MAO) serves as the central source of truth for inventory, while Shopify is where customers engage and place orders, a clean separation that suits enterprise omnichannel retail.
How SDG integrates Manhattan Active Omni (MAO) with Shopify
We implement the native Manhattan Active Omni (MAO) Shopify integration and extend it to your operating model. Inventory is governed through Manhattan’s Available to Commerce (ATC) feature: you define Views that expose exactly the right segments to Shopify, separating wholesale from retail, surfacing on-hand and in-transit stock, and protecting inventory by channel, while threshold rules push near-real-time updates to the storefront via Shopify’s inventory APIs. Orders flow from Shopify to MAO through webhooks on creation, cancellation, and modification, and payment capture and refunds are orchestrated through Shopify’s orderCapture and refundCreate GraphQL mutations so financial records reconcile automatically. Shop Pay is supported even in external checkout through the Shop Pay Component.
Enterprise omnichannel without the guesswork
MAO is chosen by retailers with serious omnichannel complexity, and it rewards experienced hands. We bring that experience, with senior engineers owning the integration. Explore our integration practice or our migration approach.
Intelligent fulfillment that protects margin and conversion
Manhattan Active Omni (MAO) is built to orchestrate fulfillment, not just record it. It evaluates customer proximity, shipping cost, delivery preference, and real-time inventory across stores, warehouses, and 3PLs to source each order from the optimal location, applying available-to-promise logic and machine-learning-driven routing. Accurate, dynamic availability and dependable delivery promising lift conversion, while optimized routing and consolidation reduce shipping cost. Because the integration ships with pre-built connectors, data mapping, and business logic, you also avoid the heavy custom build that joining two systems of this scale usually demands, which is where Manhattan’s in-app Fulfillment Insights and Postgame Spotlight analytics earn their keep.
