Connect Shopify to Manhattan OMS to sync inventory, orders, and shipment updates across channels, reducing oversells and speeding up pick, pack, and delivery.
• Shopify order events (create, paid, canceled, address updates) are routed to Manhattan OMS via API or middleware, with idempotency keys to prevent duplicate submissions.
• Customer, shipping, tax, discount, and line-level attributes are mapped from Shopify to Manhattan order schemas, including split-ship and partial-cancel scenarios.
• Inventory availability is owned by Manhattan OMS; ATP and node-level quantities are synced to Shopify as sellable inventory or location stock, depending on store model.
• Fulfillment lifecycle updates from Manhattan (allocated, released, picked, shipped) are translated into Shopify fulfillments, including multi-package tracking numbers.
• Refund and cancellation decisions initiated in Manhattan are pushed back to Shopify with reason codes and line-level quantities to keep financial and operational states aligned.
• Delta-based sync sends only changed records; retries, dead-letter queues, and audit logs capture failures, payloads, and correlation IDs for traceability.

We connect Shopify order creation to Manhattan OMS APIs or middleware, then write back shipment, tracking, cancellations, and returns status to Shopify. The mapping covers line splits, holds, partial fulfillments, and exception flows.
Available-to-promise by SKU, location, and selling channel can be pushed to Shopify, including safety stock rules and backorder flags. Updates can run near real time or on scheduled intervals, depending on OMS limits and traffic.
Yes, Manhattan OMS can allocate across nodes, then the integration reflects split fulfillments and multiple tracking numbers back in Shopify. We also sync fulfillment events per line item so customer support sees accurate status.
Cancellation requests from Shopify can be validated in Manhattan OMS, then confirmed back to Shopify with the final outcome. For returns, we sync RMA status and refund triggers so Shopify stays aligned with OMS decisions.
Timelines depend on OMS scope, required flows (BOPIS, split, backorders), and whether you need middleware or a direct API build. scandiweb has delivered 50+ Shopify projects and handles the integration, QA, and go-live support.
