What is the Commercetools + Manhattan OMS integration

When Commercetools runs the storefront and Manhattan OMS runs fulfillment, the gaps show up fast – cancellations that don’t release inventory, “shipped” statuses that lag behind reality, and customer service stuck reconciling orders across systems instead of solving tickets. The Commercetools – Manhattan OMS integration connects checkout to order orchestration so orders, inventory signals, and fulfillment updates move between platforms in a predictable flow. It gives teams a single operational thread from cart to shipment, while keeping Commercetools focused on commerce and Manhattan focused on inventory and fulfillment execution. This setup fits if your eCommerce stack is headless and you need Manhattan OMS as the system of record for fulfillment across warehouses, stores, or 3PLs.

How the Commercetools Manhattan OMS integration works technically

• Orders created in Commercetools are transformed into Manhattan OMS order payloads, including customer, line items, pricing, taxes, discounts, and shipping details. 

• Inventory availability is synchronized from Manhattan OMS to Commercetools as ATP or location-specific stock signals, with safety stock and reservation rules handled in OMS. 

• Order state and fulfillment milestones (allocated, picked, packed, shipped, canceled, returned) are mapped to Commercetools order and shipment states for storefront and support use. 

• Event-driven messages or scheduled delta syncs route only changed orders and inventory records, with idempotency keys preventing duplicate processing. 

• SKU, UOM, and location identifiers are normalized between systems, and mismatched mappings are rejected with structured error logs for reprocessing. 

• Refund and return updates can be reflected back to Commercetools when Manhattan OMS confirms disposition, with payment actions kept in the payment service where applicable.

Frequently Asked Questions about Commercetools Manhattan OMS integration

How do you integrate Commercetools with Manhattan OMS for order routing and fulfillment status updates?

We connect Commercetools orders to Manhattan OMS via APIs and event-driven messaging, then map each OMS milestone back to Commercetools order states. You get consistent “allocated,” “picked,” “shipped,” and “canceled” signals across channels.

What data should sync between Manhattan OMS and Commercetools to prevent overselling and stockouts?

At minimum, sync ATP or available-to-sell inventory, reservations, releases, and shipment confirmations at SKU and location level. This keeps the storefront stock accurate even when stores, warehouses, and 3PLs are all fulfilling.

Can a Commercetools and Manhattan OMS integration support multi-warehouse, ship-from-store, and split shipments?

Yes – Manhattan can orchestrate complex fulfillment, while Commercetools receives split shipment IDs, tracking, and partial fulfillment updates. We align the data model so customer-facing statuses stay clear and support teams can trace every package.

How do you handle returns and refunds when Manhattan OMS is the fulfillment system and Commercetools runs checkout?

We pass return events and item conditions from Manhattan OMS into Commercetools, then trigger the right refund or exchange flow in your payment setup. The goal is one source of truth for return state, not spreadsheets.
